Social impact

Impact

1

Integrated farming systems for small and marginal farmers in IGP

Irrigated as well rainfed areas in IGPs

Round-the-year employment opportunities, improved income, and also the livelihood

There was an increase in income of more than 100% and up to 6 times increase in food production

2

Crop diversification in rice-wheat system

Rice-wheat growing areas of 12 Mha in IGP

 

Development of resilience and assured income and lesser cost of production. Ensuring social security by minimizing the risk in production

Lesser use of pesticides, better management of biotic and abiotic stresses, increased income ranging from 20-35% from different crop diversification modules

3

Sub-surface drip fertigation in a maize-based system

In irrigated areas of IGP regions

Better management of crop production, timely farm operations, lesser drudgery in farm activities

Increase nutrient use efficiency by up to 80%, lesser nutrient losses, and better crop yield, enhancing the farm income

4

Organic and natural farming

In low input use areas and on the bank of Ganga

Quality food and lesser or no toxic chemical residue in edible items lead to better soil, plant, and human health and quality of social life.

The improved agronomic interventions in terms of different organic nutrient sources and crop diversification enhanced crop yield and also the farmer's income. However, the natural framing interventions lead to enhanced income in low-input used areas. The jeevamrait, beejamrat, achchhadan, whapsa also improve soil microbial activities and better resilience and hence better crop growth and overall economics.

Integrated crop management (ICM)

~ 3.0 Mha covered under CA in India

Machinery use makes CA-based ICM a more viable option than conventional practices. Also, synergistic effects of the ICM components are reflected in complimenting the supply of nutrients besides conserving soil fertility.  Likewise, these practices upheld enhanced environmental quality compared to conventional ICMs, attributable to lower fuel, labor, and better socio-economic life.

Our long-term results outlined that the residue retained CA-based ICMs (ZT direct seeded rice-ZT wheat) had a positive impact on the system yields (10-14%) and farm economics (19-22%) than CT practices.  CA-based ICM modules saved 8-12% water and increased the system water productivity by14-16% more than the CT-transplanted rice and wheat. In maize-wheat rotation, adoption of CA-based ICM practices had 16.5-22.9% greater maize grain equivalents than that of the CT-based ICMs

Neem coated Urea

Across the Country

Neem-coated urea technology is adopted by the fertilizer industry in India and from 1st Sep 2015, 100% of urea produced is neem-coated urea.

IARI's Neem coated urea technology saves 5kg urea for each bag sold in the Country every year which leads to soil health improvement, a reduction in usage of plant protection chemicals, and an increase in crop productivity.

Efficient natural resource management through the adoption of conservation agriculture

Two major innovations—the development of new-generation farm machinery and effective herbicides—have reshaped crop production practices. These advancements have rendered traditional plowing obsolete for tasks such as sowing, fertilizer placement, and weeding. Modern farm machinery enables precise seed and fertilizer placement at optimal depths, even in fields with standing or loose crop residues. This facilitates effective residue mulching, which conserves soil moisture, regulates temperature, and suppresses weeds. The introduction of innovative herbicide molecules has further transformed weed management, reducing the reliance on mechanical weeding and encouraging minimal soil disturbance. Combined, these technologies have made CA the fastest-adopted agricultural practice globally, including in India, where labor scarcity, soil degradation, declining productivity, rising input costs, and low farmer income necessitate a shift from conventional systems.

 

·           Residual contribution of P through mineralization

·           The sub-surface placement-based approach of P fertilization

·           Designing the crop rotation prioritizing mycotrophic plants like legume and maize, favoring the establishment of AM fungi

·           Maintaining a favorable moisture regime in soil.

 

·        Awareness of not using urea as surface broadcasting under residue retained condition increased NUE.

·        Sub-surface placement, band placement or point placement of urea is advisable depending upon the crop and this leads to increased crop productivity.

·        Split the N dose according to the crop need and soil condition.

·        Coated fertilizer or slow-release fertilizer can be a better option for reducing the loss of N.

·        Facilitate better drainage in the field or avoid water stagnation. For crops like rice in the CA system, alternate wetting and drying-based irrigation strategies should be followed.

·        Under residue retained condition, give preference to NO3 fertilizers instead of NH4-based fertilizers.

·        Include a legume component in the crop rotation.

·        Under heavy weed pressure, recommendation of not to apply N fertilizer. First, managing the weeds, then only going for fertilizer application helped in increased farm productivity and also income.

Developing precision management protocols for predominant cropping systems under irrigated and rainfed conditions

Water, Nutrient, and other non-monetary inputs and their usage in different crops were optimized. The nano-fertilizers were found effective in enhancing nutrient-use efficiency and saving chemical fertilizer doses up to 25-30%.

 

Precision water management ensures substantial savings (up to 35%) due to deficit irrigation scheduling and water-saving practices including the use of crop residues and cover and intercropping. Also, nutrient losses were reduced and NUE increased due to innovative nutrient sources, refined methods of applications, etc.

The cost of production was reduced, and this helped increase the net farm income from the farming.

Weed management protocols for major cropping systems

Weed dynamics, productivity and resource-use efficiency of pigeonpea-wheat cropping system as influenced by weed management, develop viable weed management option in maize-wheat cropping system, Weed and pest dynamics under CA-based cropping system

, weed management options for higher productivity of cotton

 

Weed causes maximum yield loss in different crops and is the main reason for low farm income. The different improved agronomy for crops and cropping systems were developed to enhance resource use efficiency and ultimately make the agri-food system suitable in the long run.

The weed management protocols were disseminated to farmer fields to address various weed problems. There was clear impact on crop and farm productivity, the resilience was built up in major cropping systems under diverse scenarios under IGPs.
