Influence of Different Residue Retention and Nutrient Levels on Crop Productivity of Soybean (Glycine max L.) under Conservation Agriculture

During the kharif season of 2020-22, a field experiment with soybean in soybean-wheat cropping system was conducted at ICAR-Indian Institute Soil Science, Bhopal, (M.P.) to assess effect different levels crop residue retention treatments and nutrient doses on growth parameters, physiological indices, yield attributes, profitability soybean. The laid out Factorial Randomized Block Design (FRBD) comprised 16 combinations 4 level (0%, 30%, 60% 90%) (N1-RDF (120:60:40 kg N, P2O5 K2O ha-1), N2-75% N+100% ha-1, N3-75% P2O5+100% N N4-75% K2O+100% ha-1) 3 replication under ongoing CRP-CA (Consortium Research Platform Conservation Agriculture). result showed that indices as well yield, attributes were significantly higher 90% than other reside treatment. (90%) resulted 16% grain 16.88% stover 17.55% then without Among 100% RDF better all stages. Significantly seed (1226 (2274 yields recorded any management practices.
