Abstract
The field experiment was conducted during rabi season, 2022 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj (U.P) to study the “Response of Nitrogen and Phosphorus on Growth, Yield and Economics of Fodder Maize (Zea mays L.)". The results showed that treatment 9 [Nitrogen (100 kg/ha) + Phosphorus (50 kg/ha)] recorded significantly higher plant height (164.67 cm), maximum number of leaves/plant (15.24), maximum plant dry weight (75.81 g), maximum stem girth (3.33 cm), higher green forage yield (47.90 t/ha), maximum moisture content (84.02 %) and maximum crude protein content (7.57 %) compare to other treatment. The maximum gross return (119750.00 INR/ha), maximum net return (83883.77 INR/ha) and highest B:C ratio (2.33) was also recorded in treatment 9 [Nitrogen (100 kg/ha) + Phosphorus (50 kg/ha)] as compared to other treatments.
Keywords: Fodder maize, nitrogen, phosphorus, growth, yield and economics
