Abstract
A field experiment was conducted during kharif season (2022) at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.). The treatments consisted of 3 levels of Phosphorous (30, 40, 50 kg ha-1) and 3 levels of micronutrients (Zn-0.5%), (B-0.5%) (Fe-0.5%). The experiment was laid out in Randomized Block Design with 10 treatments and replicated thrice. The results reported that the application of 50kg ha-1 Phosphorous + 0.5% Zinc (treatment -7) recorded maximum plant height (160.7 cm), Maximum plant dry weight (74.60 g plant-1), No. of corns per plant (1.77), corn length (19.3 cm), corn yield (10.06 t ha-1), green fodder yield (28.43 t ha-1). Maximum gross return (1,20501.00 INR ha-1), net return (77,444.00 INR ha-1) and B:C ratio (1.80) were recorded in (treatment -7) that is with 50 kg ha-1 Phosphorous + 0.5% Zinc.
