Abstract

Enhancing production sustainably in oilseeds has been a challenge for the technologists and policy planners. This study focuses on the efforts made through various technological interventions on farmers’ field under Cluster Frontline Demonstration (CFLD) in increasing production of soybean [Glycine max (L.) Merr.] crop. A total of 27,069 CFLDs on soybean crop were conducted (2018–22) across the country using improved crop varieties (47) and recommended practices (RP). This study aimed to compare the performance of enhanced soybean varieties over farmers' practices (FP). Most of these CFLDs were carried out using variety KDS-726. Four of these 47 varieties (KDS-726, JS 20-34, JS 20-69, and KDS-753) accounted for approximately 49.5% of the demonstrations. Under RP, the cultivars PS-1225 and PS-1235's showed highest and lowest yielding capacities, respectively. Under RP, the extent of difference in yield between the highest and lowest was 213.4%. All the soybean cultivars grown under RP could result in increasing the yield above FP ranging from 1.65 (PS-1225) to 136.8% (VL Soya-77). Under RP and FP, the cost of cultivation for the various soybean cultivars ranged from ₹30,665 to ₹27,074/ha, respectively. Sikkim Pahenlo Bhatmas-1 (₹79,850/ha) and JS 95-60 (₹58,756/ha) showed the highest net returns while MACS-1407 (₹18,250/ha) and PS-1024 (₹6,630/ha) recorded lowest net returns for RP and FP, respectively. Under RP, SYI (sustainable yield index) ranged from 0.61 (MAUS-158) to 0.99 (MAUS-612) while under FP, it ranged from 0.27 (RVS 2001-4) to 0.99 (JS 97-52). Varieties under RP consistently displayed greater SVI (sustainable value index) values than FP in terms of net returns. The key insight suggested that improved soybean varieties have been instrumental in increasing yield and bridging the yield gap.
