A field experiment was conducted at Research cum Instructional Farm, IGKV, Raipur during kharif 2017 and 2018 to evaluate the performance of organic sources city compost with integrated nutrient management on growth, yield and economics of scented rice varieties. The five treatments of INM viz. No fertilizer (N1), 75% RDN through city compost + PSB + Azotobacter + BGA (N2), 75% RDN through FYM + PSB + Azotobacter + BGA (N3), 50% RDN through city compost + 50% RDN through chemical fertilizers (N4) and 50% RDN through FYM + 50% RDN through chemical fertilizers (N5), where in sub-plotscented rice variety was taken i.e. Chhattisgarh Dubraj selection-1 (V1), Jawaphool (V2) and TCDM-1 (Trombay Chhattisgarh Dubraj Mutant-1) (V3) were tested in split plot design with 5 main plots and 3 sub plots in 3 replications. Chickpea variety JG-130 was taken as test crop during the course of investigations with 5 residual of kharif and direct effect of nutrient management in Rabi season i.e. No fertilizer (RN1), 75% RDN through city compost + PSB + Azotobacter + BGA (RN2), 75% RDN through FYM + PSB + Azotobacter + BGA (RN3), 50% RDN through city compost + 50% RDN through chemical fertilizers(RN4) and50% RDN through FYM + 50% RDN through chemical fertilizers (RN5), where in sub-plotdirect effect of nutrient management was taken i.e. No fertilizer (T1), Rhizobium + PSB + Trichoderma (T2), andRhizobium + PSB + Trichoderma + 25:60:0 N, P2O5 and K2O kg ha-1 through chemical fertilizer (T3) with the variety of chickpea JG-130. The residual effect of city compost and FYM in combination with biofertilizers applied in kharif rice, the direct application of Rhizobium + PSB + Trichoderma+ 25:60:0 N, P2O5 and K2O kg ha-1 (T3) through chemical fertilizer in rabi chickpearesulted significantly highest yield, growth parameter, seed yield, stover yield, harvest index, protein percent, and protein yield and it was comparable with Rhizobium + PSB + Trichoderma (T2).
