Integrated nutrient management showed significant influence on productivity and nutrient uptake of blackgram. Application of 25% RDF+FYM 2.5 tonnes/ha along with <i>Rhizobium</i>+PSB registered maximum improvement in seed yield (1 342 kg/ha) which was 18.2% higher than 100% RDF. Treatment receiving 75% RDF with vermicompost 0.63 tonnes/ha gave maximum N and P uptake. Residual effect of integrated nutrient management practices was also equally effective in improving the yield and nutrient uptake of mustard. Application of FYM 5 tonnes/ha along with <i>Rhizobium</i>+PSB recorded the highest seed yield of mustard (1 642 kg/ha), followed by treatments receiving 25% RDP+vermicompost 1.25 tonnes/ha with <i>Rhizobium</i>+PSB (1 600 kg/ha) and 25% RDF+FYM 2.5 tonnes/ha with <i>Rhizobium</i>+PSB (1 594 kg/ha). Similar trend was also observed for N and P uptake. Maximum net returns (Rs 50 342/ha) with B: C ratio (3.2) was obtained from treatment receiving 25% RDF+FYM 2.5 tonnes/ha with <i>Rhizobium</i>+PSB. 收起
