The experiment was done in randomized block design (RBD) with three replication and nine treatments. Treatments were T1: Control, T2: 100% RDF (18:48:0 kg t ha-1), T3: 100% vermicompost (3.00 t ha-1), T4: 75% RDF + 25% vermicompost (0.75 t ha-1), T5: 50% RDF + 50% vermicompost (1.5 t ha-1), T6: 25% RDF + 75% vermicompost (2.25 t ha-1), T7: 75% RDF + 25% vermicompost (0.75 t ha-1) + biofertilizers (Rhizobium + PSB), T8: 50% RDF + 50% vermicompost (1.5 t ha-1) + biofertilizers (Rhizobium + PSB) and T9: 25% RDF + 75% vermicompost (2.25 t ha-1) + biofertilizers (Rhizobium + PSB). Based on the experiment investigation, it was found that integrated nutrient management had significant effect on the growth parameters (plant height and dry matter accumulation), yield attributing characters (number of branches per plant, number of pods per plant and number of seeds per pod), yield (grain yield, straw yield and biological yield), NPK content in seed and straw, NPK uptake in grain and straw, NPK content in soil after harvest, net returns and benefit-cost ratio of chickpea. Among the different treatments maximum value of these parameters were recorded in the treatment with integration of 75% RDF + 25% vermicompost (0.75 t ha-1) + biofertilizers (Rhizobium + PSB) which in most of the cases was at par with 75% RDF + 25% vermicompost (0.75 t ha-1) and 100% RDF (18:48:0 kg t ha-1) but significantly higher to rest of the treatments and the minimum success was obtained in control. While the 100 seed weight and harvest index data were found to be non-significant. Treatment with 100% vermicompost has more K in soil after harvest. Also treatment with 100% RDF has more N and P in soil after harvest.EnglishThesis
