International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad Conclusion The reasons for this were lack of NSA mandate, lack of induction program with nutrition topic, lack of resources, manpower, knowledge and awareness, lack of commitment, responsibility, lack of collaborations with other institutions, low availability or use ICE/ICT material and administrational problems. Immediate action is needed to train the EAS staff on nutritional concepts to achieve the Sustainable developmental goals (SDGs). References Gomez, M. I., Barrett, C.

Intercropping in maize with short duration legumes, oilseeds and others has potential to obtain high productivity and profitability at low water use without reducing its own yield (Sharma et al., 2013) Intercropping provides insurance against crop failure or unstable market prices. Inclusion of legumes in a system as intercrop, not only supplement nitrogen to the base crop but also increases the amount 877 | Page Institutional and policy innovations for accelerated and enhanced impacts

A field experiment was carried out at research farm <strong>of</strong> Advanced Centre for Dryland<br />

Agriculture, Sher-e-Kashmir University <strong>of</strong> Agricultural Sciences and Technology <strong>of</strong> Jammu at<br />

Rakh Dhiansar during Kharif, 2020. Experiment comprises <strong>of</strong> nine treatments viz: - Maize,<br />

Cowpea, Green gram, Marrigold, Blackgram, Maize + Cowpea (1:1), Maize + Greengram<br />

(1:1), Maize + Marrigold (1:1), Maize + Blackgram (1:1) were tested in randomized block<br />

design under sandy loam soil having slightly acidic in nature, well drained low in carbon,<br />

(0.22), low in available nitrogen (162 kg ha -1 ) and potassium (102 kg ha -1 ) and medimum in<br />

available phosphorous (14.4 kg ha -1 ). Maize, Cowpea, Black gram, Green gram and Marigold<br />

were sown under different cropping sequences as per technical programme given during Kharif<br />

2020 and the recommended package and practices were followed as per the crop sown.<br />
