The soil was sandy loam in texture, low in available N and medium in available Pand K. The experiment consisted of eight treatments for cotton viz; control, 50% RDF, 100% RDF, Mungean Intercrop Incorporation (MII), FYM, 50% RDF + MII, 50% RDF + FYM and 50% RDF + FYM + Mil. For succeeding sunflower, each plot of cotton was taken as main plot and it was divided into three sub-plots, wherein three levels of fertilizer viz; 0, 50% and 100% RDF were applied. The trial in cotton was laid out in Randomized Block Design and that of Sunflower in Split Plot Design with three replications. Growth parameters yield attributes and yield of cotton were significantly influenced by nutrient management practices. Highest values of dry matter production per plant, bolls per plant, boll weight and seed cotton yield were observed with combined application of 50% RDF + FYM + Mungbeam Intercrop Incorporation. N management practices on cotton left behind a marked effect on growth, yield attributes and yield of succeeding sunflower crop. However, direct effect on N application to sunflower was more pronounced than that of residual effect. 收起
