The experiment was conducted to study the integrated nutrient management for high productivity and net returns in lentil. Results revealed that nodulation was significantly (Pâ‰¥0.01) enhanced in treatments comprising of Rhizobium and phosphate solubilizing bacteria (PSB) along with recommended dose of fertilizer (RDF), farmyard manure (FYM) and vermicompost. Treatments comprising of Rhizobium + PSB along with RDF, 50% RDF, FYM and vermicompost showed higher nodule dry weight as compared to the treatments without biofertilizers. Pods plant-1 was highest in RDF + Rhizobium + PSB. Combination of different organic sources with RDF resulted in significantly (Pâ‰¥0.001) higher grain yield than RDF only. RDF + 5 t ha-1 FYM resulted in 26.3 and 6.7 per cent higher grain yield over control and RDF alone, respectively. RDF + Rhizobium + PSB recorded the highest net returns (Rs 40321 ha-1) and B:C ratio (3.78). It can be concluded that supplementing the recommended dose of nutrients (12.5 kg N + 40 kg P2O5 ha-1) with 5 t ha-1 FYM or 2 t ha-1 vermicompost or Rhizobium + PSB inoculation help in obtaining high grain yields and net returns in lentil.
