Abstract:
An experiment was conducted during Rabi and Kharif season (2018-2020) to study the “Effects of integrated nutrient management on dry matter accumulation on rice-wheat cropping system” in the agriculture research farm department of Agronomy, Banaras Hindu University, Uttar Pradesh. The experiment was laid out in split-plot design having four nutrient levels of NL0=control, NL1= 75% recommended nutrients dose (RND) of nitrogen (N), P2O5 and K2O, NL2= 100% RND of N, P2O5 and K2O, NL3= 100% RND of N, P2O5 and K2O + 5kg iron +5kg zinc in main plot and nine combination of compost (C1=carpet waste, C2=pressmud, C3=bagasse) and biofertilizers (BF1= Pleurotus sajor-caju, BF2= Azotobacter chroococcum, BF3= Trichoderma viride) i.e. C1+BF3, C1+BF2, C1+BF1, C2+BF3, C2+BF2, C2+BF1, C3+BF3, C3+BF2, C3+BF1 assigned in sub plot. The treatment combinations were replicated three times and allocated at random in each replication. The result shows that the application of different nutrient levels with a combination of compost and biofertilizers increased the biomass accumulation of wheat and wheat. In the case of wheat, at 60 DAS the treatment combination NL3 and C1BF1 was superior in biomass accumulation over other treatment combinations. However, at 90 DAS the treatment combination NL3 and C1BF3 was found better accumulation of biomass than that of other treatment combinations. Similarly, in residual crop rice, the treatment combination NL3 and C1BF3 found higher biomass accumulation as compared to other treatment combinations at 60 and 90 DAS.
