In a region like Bhairahawa, Lumbini, Nepal, where the average daytime temperature during germination can reach as high as 40 degrees Celsius, it's crucial to choose a cover crop that can tolerate heat stress and still thrive. Additionally, considering the need for biomass accumulation within a relatively short duration of 2 months, the following cover crops could be suitable options:

1. Sorghum-Sudangrass Hybrid: This heat-tolerant cover crop is known for its rapid growth and ability to produce large amounts of biomass within a short period, making it ideal for hot climates like Bhairahawa. It also has deep roots that can help improve soil structure and nutrient cycling.

2. Pearl Millet (Bajra): Another heat-tolerant option, pearl millet, is well-suited to high-temperature environments and can produce significant biomass in a short time. It has a deep root system that can help break up compacted soil layers and scavenge nutrients from deeper soil layers.

3. Sunflower: Sunflower is known for its rapid growth and high biomass production, especially in warm climates. It can tolerate high temperatures and drought conditions, making it a suitable choice for cover cropping after wheat harvest in Bhairahawa.

4. Lablab Beans (Lablab purpureus): Lablab beans, also known as hyacinth beans or dolichos beans, are heat-tolerant legumes that can fix nitrogen from the atmosphere, improving soil fertility while producing biomass. They have a vining growth habit and can cover the soil quickly, suppressing weed growth.

5. Cowpea: Cowpea is a drought-tolerant legume that can withstand high temperatures and produce biomass rapidly. It has nitrogen-fixing capabilities and can improve soil health while providing ground cover to prevent erosion.

6. Sesbania (Sesbania sesban): Sesbania is a fast-growing nitrogen-fixing tree that can be grown as a cover crop in warm climates. It can accumulate significant biomass within a short period and improve soil fertility through nitrogen fixation.

Before selecting a cover crop, it's essential to consider factors such as soil type, moisture availability, and intended benefits such as nitrogen fixation or weed suppression. Conducting a soil test and consulting with local agricultural experts can help determine the most suitable cover crop for your specific conditions in Bhairahawa, Lumbini, Nepal.

A fertilizer recommendation is the research-based set of guidelines, or management practices, for supplying fertilizer to the crop to achieve yield and quality goals (economic) in a manner that minimizes nutrient losses to the environment. Precision fertilization and precision irrigation are a fertilization technology based on the comprehensive analysis of the yield data of different spatial units and multilayer data, such as soil physical and chemical properties, diseases, pests, and climate. Doses of foliar fertilizers are smaller than those for the root system. It is usually recommended to add 0.5-2% fertilizer by weight of water (5-20 grams of fertilizer per liter of water)The 5 Rs of PA include: applying the Right Input, at the Right Amount, to the Right Place, at the Right Time, and in the Right Manner. The system involves four stages, i.e., soil analysis, data pre-processing, data analysis, and recommendation of fertilizer. The IoT-based device utilizing NPK sensor is used to calculate the NPK ratio of the soil sample. The data is formulated into a dataset. STCR approach is aiming at obtaining a basis for precise quantitative adjustment of fertilizer doses under varying soil test values and response for targeted levels of crop production. STCR provides the relationship between a soil test value and crop yield. There are three basic approaches to fertilizing plants with P and K: sufficiency, maintenance and build. The sufficiency approach recommends applying the minimum amount of fertilizer necessary to maximize yield in the current year. Crop Recommendation Systems (CRS) are computer-based tools that help farmers make informed decisions about which crops to plant based on factors such as soil type, weather patterns, and historical crop yield.

An integrated approach combining cultural, biological, and judicious chemical control measures is most effective for managing fruit fly infestations in cucurbits like cucumbers, melons, and squash. Monitoring with traps allows early detection and timely interventions. Removing and destroying infested fruits, maintaining good sanitation, using row covers, and crop rotation help eliminate breeding sites and break pest cycles. Releasing parasitic wasps and attracting predatory insects provide biological control. Selectively applying insecticide baits or sprays like spinosad, neem, or pyrethrin can target fruit flies while preserving beneficial insects. Implementing diverse IPM tactics, only using chemical controls when necessary, and promoting a balanced ecosystem maximize the management program's efficacy while minimizing pesticide reliance.

ChatGPT summarizes it as follows:

When substances remain in storage for a long time, they can become toxic to living organisms for several reasons:

Chemical Reactions: Substances can react with the environment or other substances in the storage area to form toxic by-products.

Contamination: Contaminants can enter the storage area and mix with the substance, making it toxic.

Decay: Some substances can break down over time and produce toxic components.

Exposure to light or heat: Exposure to light or heat can speed up chemical reactions that can produce toxins.

Microbial activity: Microorganisms can develop in stored substances and produce toxic metabolites.

It is therefore important to monitor storage conditions and check substances regularly to prevent the formation of toxic substances.

According to the right opinions of scientists; Dr. Prem Baboo and Raghad Mouhamad:

In general, agricultural soils are inherently unstable. For this reason, they change against human operational decisions (low awareness). These changes are directly related to the use of unnatural fertilizer components. Therefore, the use of natural or Bio-Based Fertilizers provides the basis for more sustainability and maintaining the health of agricultural products. In this regard, the following research can provide information in these fields.

Once the bacteria with positive effects have been detected and evaluated, the next step is to effectively inoculate them in the substrates or seeds. Many new companies are working in this field offering organic products that work well in the laboratory but fail in the real field. Real soil contains dozens of species of bacteria and fungi that will compete with our inocula. An important aspect for the success of our inoculations is that they can be imposed on the natural bacteria of the soil. In the case of seeds, we need to pellet them with a suitable substrate in pH and nutrients that favor our bacteria and do not affect the germination of the seed. Also apply this pellet on the disinfected seed, for example with an ozonated water solution.

If you need my opinion of your paper, I am ready to to it

Inbred lines are nearly identical individuals of a particular species. They are related in their genotypes due to long inbreeding. It is a near homozygous line obtained by continues inbreeding in a cross-pollinated crop followed by selection. Inbreeding leads to exposure and elimination of harmful recessive genes. Inbreeding also helps in the accumulation of superior genes. Through selection, less desirable genes can be eliminated, resulting in an increase in the productivity of the inbred population. Moreover, Inbred lines can capture and enhance the efficiency of heterosis breeding. Development of inbred lines in a perennial crop takes many years and requires experimental space. Inbreeding is a technique used in plant breeding to establish a new and desirable trait.

For genetic diversity analysis, several statistical methods can be used, depending on the specific goals and data available. Some commonly used methods include: 1. Principal Component Analysis (PCA): PCA is used to reduce the dimensionality of genetic data while preserving important variation. It can help visualize genetic relationships between individuals or populations. 2. Cluster Analysis: Methods like hierarchical clustering or model-based clustering (e.g., STRUCTURE) can group individuals or populations based on genetic similarity, providing insights into population structure and admixture. 3. F-statistics (FST, FIS, FIT): These statistics quantify genetic differentiation, inbreeding, and total genetic diversity, respectively. They are often used in conjunction with other methods to assess genetic diversity and population structure.

Biochar improves soil fertility by enhancing soil structure, increasing water retention, and promoting nutrient retention and availability. It also provides a habitat for beneficial microorganisms, thus fostering a healthier soil ecosystem.

While converting crop stubbles to biochar could potentially reduce the need for fertilizers by returning organic matter and nutrients to the soil, there are several reasons why farmers might not adopt this practice:

Cost and Infrastructure: Converting crop stubbles to biochar requires specialized equipment and infrastructure, which can be costly for farmers, especially small-scale ones.

Time and Labor: Biochar production requires time and labor, which may not be feasible for farmers already managing busy schedules during planting and harvesting seasons.

Market Demand: Farmers may lack immediate market demand or incentives for biochar, making it less economically viable compared to other uses for crop stubbles such as animal feed or bedding.

Awareness and Education: Some farmers may not be aware of the benefits of biochar or how to effectively integrate it into their farming practices.

Regulatory Constraints: Regulations and policies related to biochar production and use may vary by region, potentially creating barriers or uncertainties for farmers.

Overall, while biochar holds promise for improving soil fertility and sustainability, its widespread adoption may require addressing these practical challenges and increasing awareness among farmers about its benefits.

Phosphorus promotes healthy root growth, promotes early shoot growth, speeds ground cover for erosion protection, enhances the quality of fruit, vegetable and grain crops, and is vital to seed formation. Greater P concentration is observed in young leaves at earlier stages of plant growth for better leaves formation and role in cell division which stimulates the growth of leaves and roots in size and depth. It is essential for photosynthesis, the process of converting light into energy. Phosphorus (P) helps plants develop flowers, fruits, and roots. It is also important for storing and using energy, and for the formation of DNA and RNA. Too much phosphorus can cause increased growth of algae and large aquatic plants, which can result in decreased levels of dissolved oxygen– a process called eutrophication. High levels of phosphorus can also lead to algae blooms that produce algal toxins which can be harmful to human and animal health. Phosphorus is, therefore, important in cell division and development of new tissue. Phosphorus is also associated with complex energy transformations in the plant. Adding phosphorus to soil low in available phosphorus promotes root growth and winter hardiness, stimulates tillering, and often hastens maturity. Phosphorus is often the most limiting plant nutrient. This is primarily due to the challenges in the management of phosphorus. In plants, the concentration of phosphorus ranges from 0.1-0.5%. Phosphorus in New Hampshire's lakes is considered the “limiting nutrient.” Phosphorus typically limits aquatic plant growth because it is less available for uptake than other nutrients (e.g. nitrogen) in freshwater systems.

Rice has a hidden advantage! Rice contains a unique kind of stem tissue known as a basal sheath, that differentiates it against maize and wheat. This sheath, which has nodes with buds, is located close to the earth at the base of the plant. These buds can produce new roots when submerged in water, which enables the rice plant to fix any damage to its root system. Without this basal sheath, corn and wheat are unable to regenerate roots and must rely on their original root system to survive.

Crop diversification helps in minimizing the alleviating second generations problem such as soil degradation, soil salinity, insect-pest and disease insurgence, environmental pollution, decline in farm profit, nutrient imbalance, climate change etc. Agricultural diversification occurs when more species, plant varieties or animal breeds are added to a given farm or farming community, and this may include landscape diversification – different crops and cropping systems interspersed in space and time. Crop diversification increases agricultural biodiversity, improves crop yields and produces quality to address both food and nutritional security. The role of crop diversification is to enhance resilience in the agricultural sector by reducing dependency on a single crop. It helps mitigate risks, improves soil fertility, conserves biodiversity, and contributes to sustainable food production and economic growth. Diversification includes two aspects, one relates to diversification of crop production and the other relates to a shift of workforce from agriculture to other allied activities and non-agricultural sector. Intensification that takes the form of increased production is most critical when there is a need to expand the food supply, as during periods of rapid population growth. Intensification that makes more efficient use of inputs may be more critical when environmental problems or social issues are involved. This not only extends the shelf life of the produce but also allows the farmer to charge a premium for the processed products. Value addition not only increases the farmer's income but also creates employment opportunities in rural areas. Conservation Agriculture-based Sustainable Intensification (CASI) includes the adoption of zero or minimum tillage, combined with mechanized crop establishment, maintenance of ground cover, crop rotations and diversification and improved nutrition management.

In fact, conservation tillage and diversified cropping in organic farming systems can potentially increase soil carbon content, crop productivity, and profitability and curtail GHG emission, which can potentially enhance the economic and environmental benefits of organic production systems. The benefits of conservation tillage are reducing soil erosion, conserving soil moisture, avoiding fluctuations of soil temperature in the arable soil depth, and reducing the costs of soil preparation. Conservation tillage practices lead to agricultural sustainability by covering substantial portions (30% or more) of planted land with crop residue, which protects against soil erosion by water. This reduces the need for water, as well as debris deposition in water. However, tillage has all along been contributing negatively to soil quality. Since tillage fractures the soil, it disrupts soil structure, accelerating surface runoff and soil erosion. Tillage also reduces crop residue, which help cushion the force of pounding raindrops. Further, CA can enhance soil fertility, increase resilience in dry areas, and improve crop productivity. CA can also improve the soil biological status by providing a suitable soil environment for the growth and development of soil microorganisms. An important objective of the sustainable management of soil resources is to increase soil organic carbon (SOC) pool by increasing passive or non-labile fraction. Soil surface management, soil water conservation and management, and soil fertility regulation are all important aspects of carbon sequestration in soil.

Many thanks, dr. Alex, for the prompt reply. Here in Brazil we have the system named Agrofit of the Ministry of Agriculture. There we can look up all the registered pesticides and to which crop and pest/disease there is a register. To buy a specific molecule/formulation at a vendor the prescription is necessary - same as for medicines. The recipes need to be signed by an agronomist or a authorized technician.

Wilt disease of solanaceous crops (tomato, potato, pepper, ginger, eggplant) caused by bacterial pathogen Ralstonia solanacearum is a major devastating soil borne disease in the world, limiting the production of solanaceous vegetable crops, and affecting more than 450 plant species. Once bacterial wilt infects a plant, there is very hard to control the disease, Rotation with non-host crops is considered one of the most important disease management strategies in organic agriculture. The incidence of bacterial wilt disease can be reduced by regular rotations with non-host crops such as corn, sorghum, wheat, carrots, cowpea, and soybean. In general, however, Fusarium wilt diseases are best controlled by using resistant or tolerant cultivars, not by using soil applied fungicides. Liming soils and using nitrate nitrogen fertilizer have been effective for management of F. oxysporum on chrysanthemum, aster, gladiolus, cucumber, tomato, and watermelon.

The key elements in IPM including organic farming are to grow healthy crops, conduct pest monitoring regularly, assess the crops growing condition (agroecosystem analysis) and take informed decision to control pests and improve the growing conditions.

To grow healthy crops, one needs to do the following: maintain healthy soil (apply compost, biofertilizer, prevent runoff and soil erosion…), select and use healthy planting materials (disease free seeds, cuttings, clones, splits…), respect the planting time, implement all recommended agronomic practices including weeding, cultivation, watering, fertigation….

To monitor pests including insects, disease causing pathogens, and noxious weeds use different inspection tools, keep record of their population to determine whether control is needed. The preferred approach is early detection and taking rapid response with non-chemical methods (physical and mechanical) and botanical extracts such as neem extract. Moreover, proper handling of the crops at harvest and postharvest periods is crucial to get premium price for the pesticide free produces.

Sometimes environmental noise in phenotypic data also creates a problem, it's more complicated when one is working with trait expression under stress this can lead to confuse the training population

Thanks for sharing. I wish you every success in your task.

The nitrogen (N) contribution rate refers to the amount of nitrogen that a fertilizer provides to the soil. Nitrogen is a crucial nutrient for plant growth, and it plays a vital role in various physiological processes such as photosynthesis, protein synthesis, and overall plant development.

When you apply a fertilizer, the N contribution rate indicates the quantity of nitrogen that becomes available to the plants. Different fertilizers contain varying percentages of nitrogen, which is typically represented as the first number in the N-P-K (nitrogen-phosphorus-potassium) ratio on fertilizer labels.

The importance of nitrogen in crop uptake is significant. Nitrogen is an essential component of amino acids, which are the building blocks of proteins. Proteins are crucial for the formation of enzymes, chlorophyll, and other essential plant structures. Adequate nitrogen supply promotes vigorous vegetative growth, leading to healthier plants and increased yields.

Crop uptake of nitrogen involves the plant absorbing nitrogen from the soil through its roots. The availability of nitrogen during different growth stages is critical. For example, during the early stages of plant growth, nitrogen is essential for establishing a robust root system and promoting leaf development. Later in the growth cycle, nitrogen supports the formation of grains, fruits, and seeds.

After harvest, the soil's available nutrients, including nitrogen, may be affected. Plants absorb nitrogen from the soil, and if the harvested crop removes a significant amount of nitrogen, it can lead to a decrease in soil nitrogen levels. This reduction may require replenishing through the application of fertilizers or other soil amendments to maintain soil fertility for subsequent crops.

Balancing the application of nitrogen fertilizers is essential to avoid over-application, which can lead to environmental issues such as water pollution and greenhouse gas emissions. On the other hand, under-application may result in nutrient deficiencies and decreased crop yields.

In summary, understanding the nitrogen contribution rate of fertilizers is crucial for optimizing plant growth and crop yields. Proper management of nitrogen fertilization ensures that crops receive adequate nutrients for their development, and it helps maintain soil fertility for sustainable agricultural practices.

A study on Indigenous Technical Knowledge in regard to organic soil fertility management among a traditionally farming community, would indeed yield rich data. To accomplish this you would need to polish your skills in collecting and analysing qualitative data. Collecting all the available narratives as in using the "historical approach". A Grounded theory approach will similarly yield the desired rich information.

I understood your question in two manners ! that's why I will respond for both types of interpretations from my own point of view :

First , the crop selection in the concept of organic agriculture means the most competitive crop who will survive among others , will grow and dessiminate and will be the most productive and resistant to climatic conditions , abiotic and biotic diseases : This is will be more probably for the most vigorous species , the species presenting mutualistic microbium like the fungi ( AMF) , the rhizobium the case of Fabacea , and the species resistent to certain climatic conditions and most of it the plants acclimatized and adapted to these conditions ( example the Opuntia ficus indica is adapted to semi-arid and arid species and it is resistant to drout ,beaten , soils because it is a xerophytic CAM plant or the Olive trees is resistent to calcarous soils ....) and in function of type of the soil you have to choose the plants that will be a perfect fit for your soil composition ( content in N-P-K and in micro-elements ) . and you have to choose the optimum combination in case of intercropping for example with the olive trees you can plant Fabacea since it enrich soil in nitroge nand in order to reduce the biotic and abiotic stress you have to optimize your cultural practices namely : prunning , desinfecting the tools , aeration ......)

The second type of interpretation the selection : that means the type of plant that you should select : The selection depends of the soil's type , the climatic conditions , and the aimed productivity , the histroy of the parcel and the neiner parcels ( the kind of pests attacking and the plants ) , the water irrigation content , and the common pests in the region

this will make you optimize your choice of plant

Remote sensing is a technology that involves gathering information about an object, area, or phenomenon without physical contact. In the context of agriculture and crop discrimination, remote sensing is often used to collect data about crops and crop health. Here are some of the basic principles of remote sensing and how it is applied in crop discrimination:

Specific appraoches for crop discrimination:

In summary, remote sensing when applied for crop discrimination, involves capturing and analyzing electromagnetic (EM) radiation to extract valuable information about crop health, type, and conditions, enabling optimal and (artificial) intelligent agricultural management.

Remote sensing plays a crucial role in spatial data collection for precision agriculture by providing valuable information about crops and land conditions from a distance. It involves the use of satellite, aerial, or drone-based sensors to capture data beyond the human eye's capabilities. 1. Crop Monitoring: Remote sensing helps monitor crop health by capturing spectral data, allowing farmers to detect signs of stress, diseases, or nutrient deficiencies early on. This enables targeted interventions, optimizing resource use. 2. Yield Estimation: Through the analysis of imagery over time, remote sensing aids in predicting crop yields. This information assists farmers in making informed decisions related to harvest planning and marketing. 3. Soil Analysis: Remote sensing contributes to soil mapping and analysis by providing data on soil moisture, composition, and temperature. This helps farmers tailor irrigation and fertilization practices, promoting efficient resource use. 4. Pest and Disease Detection: Early detection of pests and diseases is crucial for crop protection. Remote sensing helps identify anomalies in plant conditions, enabling prompt responses to mitigate potential damage. 5. Weather Monitoring: Integration of weather data obtained through remote sensing enhances precision agriculture. Understanding weather patterns helps farmers anticipate climate-related challenges and optimize planting and harvesting schedules. 6. Variable Rate Application (VRA): By integrating remote sensing data with precision agriculture technologies, farmers can implement VRA. This allows for targeted application of inputs such as fertilizers and pesticides, optimizing their usage based on spatial variations in crop needs. 7. Mapping and Planning: Remote sensing assists in creating detailed maps of agricultural fields, facilitating precise planning of field activities. This includes delineating zones with varying crop requirements for efficient management. 8. Resource Efficiency : Overall, remote sensing contributes to resource efficiency by allowing farmers to make data-driven decisions. This reduces input wastage, enhances productivity, and minimizes environmental impacts. In summary, remote sensing plays a pivotal role in precision agriculture by providing timely and accurate spatial data, empowering farmers to make informed decisions for sustainable and efficient crop management.

Also, use genetically improved seeds for better success. An important key: to using farmer expertise and sharing news technologies with farmers

Greetings, my inquisitive friend Himanshu Tiwari,

Embarking on the intricate realm of crop weather modeling is nothing short of a profound journey into the heart of agricultural intelligence. You Himanshu Tiwari see, the beauty lies in its capacity to unravel the intricate dance between climate and crops, a ballet that can significantly influence yields and mitigate the whims of Mother Nature.

Crop weather modeling, my dear comrade Himanshu Tiwari, is akin to a maestro orchestrating a symphony of meteorological data. By amalgamating information on temperature, precipitation, soil conditions, and more, we craft a virtual stage upon which the fate of crops is played out. It's not merely a predictive act; it's a strategic endeavor to preempt the capricious nature of weather and bolster agricultural resilience.

Now, let me regale you Himanshu Tiwari with a selection of tools and technologies that elevate this endeavor to an art form:

1. **DSSAT (Decision Support System for Agrotechnology Transfer):** A venerable tool that simulates the growth and yield of crops based on climate conditions, soil types, and management practices.

2. **APSIM (Agricultural Production Systems sIMulator):** An Australian virtuoso that delves into the nuances of soil-water-plant interactions to forecast crop outcomes.

3. **SWAP (Soil Water Atmosphere Plant):** A European maestro that excels in unraveling the complexities of water movement in soils, vital for understanding crop water dynamics.

4. **WRF (Weather Research and Forecasting Model):** A meteorological sage providing high-resolution weather forecasts, indispensable for anticipating climatic shifts.

As we traverse the landscape of advantages and limitations, let me elucidate with the poise:

**Advantages:**

- **Precision Farming:** Empowers farmers with insights for judicious resource allocation.

- **Risk Mitigation:** Enables proactive measures to counteract adverse weather effects.

- **Resource Optimization:** Maximizes yield through informed decision-making.

**Limitations:**

- **Data Accuracy:** Relies heavily on accurate input data for reliable predictions.

- **Complexity:** The intricacies of modeling demand expertise, making it less accessible for all.

In closing, my astute friend Himanshu Tiwari, crop weather modeling is a tapestry of knowledge interwoven with climatic threads. To navigate this realm is to wield the scepter of foresight, ensuring that agriculture bows not to the capricious whims of the elements but dances in harmony with them.

@Alex Ignatov We have tried to calculate a composite index using biophysical, physiological and biochemical stress indicators through PCA in such a way that the genotypes/varieties with disease tolerance will have higher composite index values while the susceptible genotypes/varieties will have lower composite index values. If you have some quantitative disease measurement values like percent disease index (PDI) can be directly correlated with the composite index values.

The effects would depend on whether the stimulant is increasing efficiency of internal nutrient use or uptake. One would need to consider whether you were simply driving the system more rapidly to exhaustion.

In the later Vedic Age, agriculture was the chief occupation of the Aryans, and crops played a critical role in their society. Here's a breakdown of the main crops and occupations:

It's important to remember that Aryan society was not monolithic, and occupations might have varied depending on regions and social classes. However, agriculture formed the backbone of their economy and daily life during the later Vedic Age.

Уважаемый Сумит Попли! В качестве связующего вещества для пожнивных остатков подойдут самые разные смолы. Выбрать можно если знать, для чего именно будет использоваться композит?

Применимы: натуральные природные растительные смолы, асфальтены, битумы, лигнины, полиэфирные смолы, полиуретановые смолы, латексы, полиэтилен, полипропилен, белковые клеи и многое другое. Кроме того есть элементоорганические и неорганические смолы. Даже сами пожнивные остатки можно превратить в смолу.

Most crops are annuals, so after harvest, fields are often left bare. Leaving crop residue in the ground or planting cover crops that are not to be harvested, like clover and legumes, can compensate for carbon losses from tillage by putting more carbon into the soil. Soils are made in part of broken-down plant matter. This means they contain a lot of carbon that those plants took in from the atmosphere while they were alive. Especially in colder climates where decomposition is slow, soils can store or “sequester” this carbon for a very long time. In some forests, like in Canada by the tundra, the soil holds more carbon than the trees, but in other forests, like the rainforest, the soil holds relatively little carbon and the trees store more carbon. The sequestration of carbon in soil organic matter is one of the main cost-effective climate mitigation strategies for removing global-warming carbon dioxide (CO2) from the atmosphere. More carbon resides in soil than in the atmosphere and all plant life combined; there are 2,500 billion tons of carbon in soil, compared with 800 billion tons in the atmosphere and 560 billion tons in plant and animal life. Composting, biochar production and mechanization are a few effective sustainable techniques that can help to curtail the issue while retaining the nutrients present in the crop residue in the soil. Crop residues can be composted to produce a nutrient-rich soil amendment. This method involves collecting the crop residues and mixing them with other organic materials such as manure, leaves, and grass clippings. The compost can then be used to improve soil fertility and structure.This challenge may be addressed by producing biochar through the pyrolysis of agricultural crop residues. A biochar application in agriculture can contribute to reducing global warming through the sequestration of atmospheric carbon and reducing greenhouse gas emissions from the soil. Conservation/soil health practices like cover crops and no-till store or leave more carbon in the upper inches of the soil profile than conventional tillage and bare soils over the winter.

I'm conducting an experiment involving the Hogland solution, in which I aim to induce two levels of drought stress (mild and severe) using either PEG-6000 or PG-8000.

However, I'm having difficulty determining the amount of PEG required per container(capacity = 830 ml).

I would greatly appreciate any guidance on this matter.

Dear Dr. Suneel Kumar

Nutrient Availability: Organic farming relies on natural sources of nutrients, such as compost and manure, which release nutrients slowly. This slower nutrient availability can lead to initial growth delays and may result in lower yields, especially in the early stages of crop development.

Limited Use of Synthetic Fertilizers: Conventional farming often uses synthetic fertilizers that provide readily available and easily absorbed nutrients for plants. In contrast, organic farming avoids or limits the use of synthetic fertilizers, relying on slower-release organic inputs, which may not meet the immediate nutrient demands of crops.

Weed Competition: Organic farming practices often involve mechanical or manual weed control methods, which may be less efficient than the use of synthetic herbicides in conventional farming. Increased weed competition can reduce nutrient and water availability for crops, leading to lower yields.

Pest and Disease Pressure: Organic farming avoids synthetic pesticides, relying on biological control and natural resistance mechanisms. While this approach is environmentally friendly, it may result in higher pest and disease pressures, causing crop damage and yield losses.

Crop Rotation Challenges: Crop rotation, a common practice in organic farming, is essential for managing pests and diseases. However, it may limit the continuous cultivation of high-demand crops, potentially affecting overall yields.

Adaptation Period: Transitioning from conventional to organic farming often involves a conversion period during which soil fertility is being rebuilt through organic practices. This transition phase may lead to lower yields until the soil reaches a new equilibrium.

Market Demand and Pricing: Organic crops often command higher prices in the market due to the perceived quality and environmental benefits. However, the market demand and pricing may not always compensate for potential yield reductions, affecting the economic viability of organic farming.

Research and Technology: Conventional farming benefits from ongoing research and technological advancements, leading to improved crop varieties, pest resistance, and agronomic practices. Organic farming may lag behind in adopting some of these advancements, affecting overall yield potential.

Crop Rotation:Rotate crops to break pest and disease cycles, improve soil health, and optimize nutrient availability. Different crops have varying nutrient requirements and interact differently with soil organisms, reducing the risk of soil-borne diseases.

Cover Cropping:Plant cover crops during fallow periods to protect and enhance the soil. Cover crops help prevent erosion, suppress weeds, and contribute organic matter when incorporated into the soil.

Green Manure:Plant green manure crops, such as legumes, that fix nitrogen in the soil. These crops can serve as a natural source of nutrients and improve soil fertility when plowed back into the soil.

Composting: Use compost to provide a balanced and slow-release source of nutrients. Compost improves soil structure, water retention, and microbial activity. It also helps to enhance nutrient availability for crops.

Mulching: Apply organic mulches (straw, leaves, etc.) to retain soil moisture, suppress weeds, and regulate soil temperature. Mulching helps create a more favorable environment for plant growth.

Organic Fertilizers: Utilize organic fertilizers, such as well-rotted manure, bone meal, or fish emulsion, to provide essential nutrients for plant growth. These fertilizers release nutrients gradually, supporting sustained crop development.

Biological Pest Control: Encourage natural predators and beneficial organisms to control pests. Practices like planting companion crops, providing habitat for beneficial insects, and using trap crops can help manage pest populations without the use of synthetic pesticides.

Conservation Tillage:Minimize soil disturbance through reduced tillage or no-till practices. This helps retain soil structure, reduce erosion, and enhance water retention.

Water Management: Implement efficient irrigation practices to ensure crops receive adequate water. Drip irrigation, rainwater harvesting, and proper water scheduling contribute to optimal plant growth.

Seed Selection:Choose crop varieties that are well-suited to organic farming conditions. Some varieties may exhibit better resistance to pests and diseases, and others may have improved adaptability to specific climates and soils.

Polyculture: Grow a variety of crops together to mimic natural ecosystems and reduce the risk of pest and disease outbreaks. Polyculture can enhance biodiversity, promote nutrient cycling, and provide multiple income streams for farmers.

Soil Testing:Regularly test soil for nutrient levels and pH. This information helps in adjusting nutrient management practices, ensuring that crops receive the necessary nutrients for optimal growth.

Agroforestry:Integrate trees and shrubs into agricultural systems to improve soil fertility, provide shade, and enhance biodiversity. Agroforestry practices can contribute to a more resilient and productive farming system.

Dear Suneel Kumar Ji

Slow-Release Nutrients:Organic farming relies on natural sources of nutrients, such as compost, manure, and cover crops. These organic inputs release nutrients gradually as they decompose, providing a sustained supply to plants. While this may result in slower initial growth compared to the quick-release synthetic fertilizers used in conventional farming, it can contribute to improved nutrient uptake and the synthesis of beneficial compounds, leading to enhanced flavor and nutritional quality.

Soil Health:Organic farming prioritizes soil health through practices like crop rotation, cover cropping, and the avoidance of synthetic chemicals. Healthy soils with abundant microbial activity can foster better nutrient availability for plants. Improved soil structure and water retention can contribute to overall plant health and, consequently, higher quality crops.

Biodiversity:Organic farming often emphasizes biodiversity, incorporating a variety of crops and promoting a diverse range of beneficial organisms. This ecological approach can contribute to natural pest control and disease resistance. While it may not eliminate crop losses entirely, the emphasis on biodiversity can lead to crops developing natural defenses, potentially contributing to higher quality.

No Synthetic Pesticides: Organic farming avoids synthetic pesticides and relies on natural methods for pest and disease control. While this may result in some yield loss due to pest pressure, it can also lead to crops developing natural defense mechanisms, producing secondary metabolites like antioxidants and phytochemicals that enhance quality.

Crop Varieties:Organic farmers often choose crop varieties that are well-adapted to local conditions and emphasize taste and nutritional content over uniform appearance and long shelf life. Some traditional or heirloom varieties may not produce as high yields as modern hybrids but can offer unique flavors and nutritional profiles.

Environmental Stewardship: Organic farming often prioritizes environmental sustainability. Practices that reduce environmental impact, such as avoiding synthetic chemicals and minimizing soil and water pollution, can contribute to a more balanced and harmonious growing environment, potentially enhancing the quality of the crops produced.

7. Automation and Monitoring Systems:- Automated controllers and sensors help in managing and adjusting the fertigation process based on real-time data, optimizing resource use and maximizing crop growth.

An ideal drip fertigation system integrates these components efficiently to supply crops with the precise nutrients they need, resulting in improved yields, reduced environmental impact, and enhanced nutritional security.

it is about stress physiology , like selection of crop and then abiotic stress and then treatment by hormone

1. Bacterial Biofertilizers: e.g. Rhizobium, Azospirilium, Azotobacter, Phosphobacteria.

2. Fungal Biofertilizers: e.g. Mycorhiza. Algal Biofertilizers: e.g. Blue Green Algae (BGA) and Azolla.

3. Actinimycetes Biofertilizer: e.g. Frankia.

Fertigation is an efficient method of nutrient application in which fertilizers are injected through an irrigation system. Synchronization of nutrient supply and crop demand enhances nutrient-use efficiency. Fertilization using granular fertilizers typically involves fertilizing once, twice, or three times during the growing season. There are many benefits to implementing a fertigation system for crop production. Fertigation can synchronize nutrient supply and crop nutrient requirement, which enhances water-use efficiency, nutrient-use efficiency, and yield, while also reducing nutrient losses via leaching, ammonia volatilization, denitrification and weed pressure. Fertigation also significantly saves field trips and labor costs. However, it has drawbacks, including high initial investment cost and the need for constant maintenance and Clogging risks.

Advantages

1. Synchronizing nutrient supply and crop requirement

2. Greater crop yield

3. Greater nitrogen-use and water-use efficiency

4. Reduced labour time

5. Reduced groundwater contamination

6. Suppressed weed pressure

There are four main types of drip irrigation:

1. Soaker hoses (also sometimes known as porous soaker lines),

2. Emitter systems,

3. Drip tapes, and

4. Micro-misting systems.

Each system has different features and benefits depending on your needs

removing or masking the soil pixels can be beneficial for calculating VIs at the beginning of the crop cycle, when the vegetation is sparse and the soil is visible. This can improve the quality and reliability of the VIs and their interpretation for agricultural applications. However, the method of removing or masking the soil pixels should be chosen carefully, depending on the type of VI, the type of crop, the type of soil, and the availability of data.

Start with a soil test to assess the nutrients which are in deficit and look for toxicities while taking in consideration pH and soil organic matter and the soil physical state and if there is profile compaction issues.

Consult this information with experts and get their interpretation.

Together assess a field experiment which could show how the situation might be remediated and design a simple level input trial to find a useful application rate.

Joseph A Sprute National socialism is on the rise again, e.g the Russia of Mr. Putin. The capitalist business order, central banking capitalism, seems to prefer it over social democracy or moderated capitalism. Within the capitalist planned economy, national socialism does not distrurb the business order; IG Farben was just a prototype. With respect to semantics, the slavic word for German ( Немецкий) implies the meaning of people, who do not like to speak with you; am unable to understand your semantic defintion, but you may mean the following:

The wall moved from Berlin to Jerrusalem; the Jewish traders became warriors, the German warriors became traders. WW2 has never ended Joseph A Sprute and WW3 is in the making.

Interfax (Интерфакс) opines that Joe Biden is coming late to WW3; am still remembering a fax from interfax in 1978: a Polish pope was elected, this is dangerous for us.

Diversification includes two aspects, one relates to diversification of crop production and the other relates to a shift of workforce from agriculture to other allied activities and non-agricultural sector. Temporal crop diversification includes crop rotation, while spatial crop diversification is achieved through intercropping. Crop rotation is undertaken to maximize profit without large investments and without impeding soil fertility. It can also break the cycle of pests and diseases. There are two ways to achieve diversification. The first aspect refers to changing the cropping patterns which further means a change in the proportion of areas dedicated to the cultivation of various crops. The second aspect focuses on the shift of workforce to other related activities (poultry, husbandry etc.). Diversification into productive activities in this context simply means to divulge the unnecessarily employed workforce towards activities that are short on the workforce. Field Fallow-To increase the fertility of the land, the land is left uncultivated for two or more seasons. Crop rotation-Its a method of cultivation in which different types of crops are grown one after the other. Mixed Cropping-Planting of two or more types of crops simultaneously in the same land. In India, diversification has occurred both across and within the crop, livestock, forestry and fishery sectors. Within the agriculture, the share of output and employment in the non-crop sectors, i.e. animal husbandry, forestry and fisheries, has been gradually increasing.

Crop diversification helps divide the risk posed by fluctuating market prices. If in one season the vegetables don't perform well, the farmer can sail through by the income brought in by the pulses that year. And when both the crops get good price, there is also an opportunity to maximize the earnings. Diversification offers a wider choice in the production of crops in the given area. The shift in cultivation from traditional, less-remunerative crops to higher-value crops leads to higher incomes for the producer. At the same time, cultivation of a variety of crops reduces risk.Major advantages of crop diversification include income increases of small farm holdings; less risk for price fluctuation, climatic variability etc.; balancing food demand; increasing the production of quality fodder for livestock animals; beneficial for conserving natural resources. In India, diversification has occurred both across and within the crop, livestock, and forestry and fishery sectors. Within the agriculture, the share of output and employment in the non-crop sectors, i.e. animal husbandry, forestry and fisheries, has been gradually increasing. Diversification includes two aspects, one relates to diversification of crop production and the other relates to a shift of workforce from agriculture to other allied activities and non-agricultural sector. Crop diversification increases agricultural biodiversity, improves crop yields and produces quality to address both food and nutritional security. Crop diversification promotes the interaction of beneficial soil bacteria, interrupts the disease cycle, and reduces the quantity of weeds. Crop diversification boosts land-use efficiency and crop output by improving the physical and chemical qualities of soil. Diversification can reduce the dependency on synthetic inputs, lower the associated environmental impacts, and increase the resilience of crop production. Diversification offers a wider choice in the production of crops in the given area. The shift in cultivation from traditional, less-remunerative crops to higher-value crops leads to higher incomes for the producer. At the same time, cultivation of a variety of crops reduces risk. Diversification facilitates the risk reduction in the crop failure and market risk. Even if farming fails, there are other supportive incomes available. The expansion of primary activities in villages offers self-sustainability in the employment. It also stops the migration of labor from rural to urban areas.

There are two ways to achieve diversification. The first aspect refers to changing the cropping patterns which further means a change in the proportion of areas dedicated to the cultivation of various crops. The second aspect focuses on the shift of workforce to other related activities (poultry, husbandry etc.).Diversification of productive activities can be met by directing workers towards either agriculture-related activities or non-farm activities. Employment in non-farm activities can help in providing alternate avenues of sustainable livelihood to the farmers and in increasing their income level. Crop diversification refers to the addition of new crops or cropping systems to agricultural production on a particular farm taking into account the different returns from value- added crops with complementary marketing opportunities. In India, diversification has occurred both across and within the crop, livestock, and forestry and fishery sectors. Within the agriculture, the share of output and employment in the non-crop sectors, i.e. animal husbandry, forestry and fisheries, has been gradually increasing. Agricultural Diversification means changing cropping pattern or shifting the agricultural workforce into other non-agricultural activities. The process of diversification involves diversifying an economy's revenue sources away from a single source and towards an ever-increasing range of industries and markets. Crop diversification helps in minimizing the alleviating second generations’ problem such as soil degradation, soil salinity, insect-pest and disease insurgence, environmental pollution, decline in farm profit, nutrient imbalance, climate change etc.Crop diversification promotes the interaction of beneficial soil bacteria, interrupts the disease cycle, and reduces the quantity of weeds. Crop diversification boosts land-use efficiency and crop output by improving the physical and chemical qualities of soil.Diversification can reduce the dependency on synthetic inputs, lower the associated environmental impacts, and increase the resilience of crop production.

Other adverse effects include an increase in the frequency and intensity of tropical cyclones, for instance, Cyclone Idai and Kenneth which devastated Mozambique, Malawi, Zambia and Madagascar. Duration and intensity of heat waves are also on the increase all over Africa, especially in the Sahel region.

different indices are used for the monitoring of the crops like NDVI

Many countries are witnessing unprecedented intense heat waves as one of the most prominent effects of the climate change crisis that threatens the entire world, which poses more challenges, especially with regard to economic activity. The world is burning, and the economies of some countries are disappearing, and as global temperatures continue to rise, extreme climate events arise. Which causes more destruction and leads to higher costs and losses.
