Impact of Organic Manure, Inorganic Fertilizers and Bioinoculants on Production and Economics of Wheat (Triticum aestivum L.)

Field trials were undertaken to investigate the impact of integrated nutrient management on wheat yield and economic aspects during the Rabi season of 2021-22 and 2022-23. The experimentation took place at the student's instructional farm of Chandra Shekhar Azad University of Agriculture & Technology in Kanpur. The study encompassed 11 treatment combinations, organized in a randomized block design with three replications. These treatments involved varying combinations of inorganic fertilizers, organic manure, and biofertilizers. The cultivation of wheat variety HD-2967 was carried out in accordance with the suggested agronomic practices. Based on the outcomes derived from the investigation, it can be deduced that among the various productivity parameters, the treatment labeled as T10 [100 % NPK + S40 + Zn5 + Fe10 + Azotobacter + PSB + 5 ton FYM] exhibited the highest grain yield of 48.60 and 49.93 quintals per hectare, straw yield of 63.15 and 67.53 quintals per hectare, and biological yield of 111.75 and 117.46 quintals per hectare across both years of experimentation. For economic factors, the treatment T10 also yielded the highest gross returns of ₹ 1,40,190 and ₹154,632 during the first year (2021-22) and second year (2022-23) of the experiment, respectively. Moreover, the treatment T7 [100 % NPK + Zn5] showcased the maximum benefit-cost ratio (B:C ratio) of 2.26 and 2.31. It is noteworthy that the highest costs of cultivation were observed in the treatment T10, amounting to ₹ 53,805 in the first year and ₹ 55,561 in the second year. This treatment encompassed a combination of 100 % NPK, S40, Zn5, Fe10, Azotobacter, PSB, and 5 tons of FYM.
