Optimizing nutrient management through an integrated plant nutrient supply (IPNS) system

This activity aims to promote soil conservation and better organic matter management. It encourages the inclusion of legumes in cropping systems and rotations as grain, forage, or green manure crops. The initiative identifies socio-economic constraints in the adoption of IPNS at community level and appropriate policy interventions and improvements. Nitrogen contributing Sesbania as green manure is being promoted in several tank command and influence areas of MIPs. Seed production of Sesbania is also being promoted in Kharif fallows or in orchards as a second crop.

Outcome

• On field pilot of IPNS at community level taking 50 farmers’ plots in three districts. The field trials aimed at nutrient use optimization
• Dhaincha as green manure, locally produced compost, and vermicompost were developed and promoted in all the trial locations
• INM intervention results more than 56% yield improvement in Blackgram, 47% in Greengram and 37% in Sesame and Maize and 14% in Groundnut in INM trial plots over Farmer practice fields in Rabi 2023
