abstract
A field experiment was conducted during kharif season of 2023 at Crop Research Farm Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Sciences and Technology. To determine “Effect of nitrogen management on growth and yield of sweetcorn”. The results revealed that treatment 4 [(75%) Nitrogen through Vermicompost + (25%) Nitrogen through Urea] recorded significantly higher plant height (134.57cm), higher plant dry weight (108.12g), maximum number of cobs/plant (1.83), maximum number of grain rows/cob (18.17), maximum number of grains/row (24.4), highest cob yield (6.47 t/ha), highest green fodder yield (14.90 t/ha), maximum gross return (131360.00 INR/ha), maximum net return (89860.00 INR/ha) and highest B:C ratio (2.17) was recorded in treatment 4 [(75%) Nitrogen through Vermicompost + (25%) Nitrogen through Urea] as compared to the other treatments was found to be productive as well as economically feasible.
