International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities
during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
Results
Pooled data revealed that significantly taller plant (66.82 cm) with higher aerial dry matter
(685.38 g/m 2 ), nodule number/plant (43.19) andseed yield (2320 kg/ha) were recorded with N5
treatmentand the lowest values were obtained under N1, whereas,seed oil content(20.15%) was
highest in 100%RDF.Interaction effects showed that variety PS 24 and nutrient treatment N5
(V3N5)excelled others in terms of plant height (73.81 cm), aerial dry matter (767.09 g/m 2 ), nodule
number/plant (51.21) and seed yield (2601kg/ha). Maximum seed oil content (21.18%) was
obtained with V2N1 combination. Highest gross return (Rs.75,448/ha), net return (Rs. 42,994/ha)
and benefit-cost ratio (2.32) was obtained with V3N5.
Conclusion
The PS 24 variety along with application of 1. 5 t/ha vermicompost plus 75% RDF and 25 ZnSO4
kg/ha can be recommended for Kharif soybean under rain-fed condition in new alluvial zone of
West Bengal.
