Abstract:
At STCR Farm, IGKV Raipur (C.G.), during the Kharif season of 2021 and 2022, field experiments were done to investigate the nutritrient requirements for targeted production of maize in a Vertisol of the Chhattisgarh plain. The treatments included various combinations of N (0, 60, 120, 180 kg ha^-1), P (0, 30, 60, 90 kg ha^-1), and K (0, 30, 60, 90 kg ha^-1), each at 4 levels. All of the strips had three levels of organic source (FYM) overlaid on them (0, 5, and 10 t ha^-1). 1.62 kg of N, 0.33 kg of P₂O₅, and 2.09 kg of K₂O were needed to create one quantal of yield of maize in order to meet the yield target.
