The mean net returns in soybean + pigeonpea intercropping system was recorded as Rs. 36695/ha as against mean sole soybean net return of Rs. 24778/ha in farmers practice. The BC ratio and RWUE was also higher in soybean: pigeonpea intercropping system as compared to sole soybean crop. During 2014 and 2015, despite of more than 50% deficit rainfall, the intercropping system sustained even in prolonged dryspell during 2015. The dryspell was occurred at flowering and pod filling stage of soybean and vegetative stage in pigeonpea. In-situ moisture conservation through broad bed & furrow (BBF) in soybean: The data on. crop yield, net return, BC ratio and RWUE under BBF technology as compared to farmers practice is presented. 244 | Page Climate resilient agriculture for risk mitigation
International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad Comparison of BBF technique with farmers practice for soybean Soil type Intervention Mean Seed yield kg/ ha Light to medium black soil Stover yield /ha kg Net returns, Rs./ha BC ratio RWUE, kg/ha-mm BBF 1337 1847 19733 1.62 2.166 Farmers practice 1122 1433 14384 1.46 1.79 Above table indicated that due to use of BBF technology, the yield increase was recorded. Similarly, the net returns, BC ratio and RWUE was found to be higher in BBF technique as compared to farmers practice. This BBF technique was proved as climate resilient technique under changing climate. Well and bore well recharging model: An Experience in NICRA Village A National Innovations on Climate Resilient Agriculture (NICRA) project in being implemented on farmers field at village Babhulgaon Tq.Dist.Parbhani. Open well and bore well recharge technology was demonstrated on 10 and 7 farmers field through participatory mode respectively. The pre-& post monsoon water levels in the wells were monitored. Also, the aquifer characteristic viz. transmissivity and specific yield were determined. Accordingly, the ground water recharge was determined. The Recharge wells recorded higher ground water potential as compared to un-recharged wells. Conclusion Preparedness like adoption of climate resilient crops and varieties, adoption of in-situ and ex-situ moisture conservation techniques i.e. Broad bed furrow sowing method, conservation furrow, farm pond, recharging of well and bore wells and intercropping system plays a crucial role in dryland agriculture for sustaining crop productivity. The Broad Bed and Furrow sowing technique (BBF) was found to be most efficient climate resilient technology under variable climatic conditions over a period of 5 years with respect to yield enhancement and thereby the increased net returns. Also, BBF technique resulted in more moisture conservation as reflected by mean soil moisture status.
