A field experiment was conducted during the kharif seasons of 2022 and 2023 at Farmers' Field in Kishorpur village, Kanpur Dehat, under the supervision of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur. The site lies in the alluvial belt of the Indo-Gangetic plains in central Uttar Pradesh, known for its fertile soil, ideal for agricultural research. There are 12 treatment combinations involved varying integration of macronutrients, i.e., N, P, K & S, micronutrients, i.e., Zn, organic manure, i.e., FYM and biofertilizers, i.e., BGA with three replications of randomized block design (RBD). The cultivation of Kalanamak variety, i.e., Kalanamak Kiran was carried out in accordance with the suggested agronomic practices. It can be concluded from the findings that the two-year results are consistent with the T7 (100 percent RDF + 25 percent N FYM + S @ 40 kg ha-1 + ZnO @ 5 kg ha-1 + BGA @ 10 kg ha-1) showed the highest values of economics parameters, i.e.,maximum cost of cultivation ₹49715 & ₹50414, gross returns of ₹145983 & ₹152878 and net return of ₹96268 & ₹102464 during the first year and second year, respectively, followed by treatment T6. The study shows that BGA, Zn, and S improve grain yield and enhance the economic viability of Kalanamak rice cultivation. It emphasizes that integrated nutrient management, combining biofertilizer and balanced fertilization, optimizes economic returns.
