Effect of nitrogen and zinc on growth and yield of sorghum (Sorghum bicolor L.)

A field experiment was conducted during kharif 2024 at the crop research farm, Department of Agronomy, SHUATS, Prayagraj (U.P.) to study the effect of nitrogen and zinc on growth and yield of sorghum (Sorghum bicolor L.). The experiment was laid out in a Randomized Block Design with three replications. Two factors was considered Nitrogen at three levels (60,80,100 kg/ha), and Zinc at three levels (10,20,30 kg/ha). The results revealed that the combined application of Nitrogen at 80 kg/ha and Zinc at 20 kg/ha significantly improved higher Plant height (147.47 cm), Length of ear head (26.40 cm), Grains/Ear head (923.62), Test weight (29.95 g), Grain yield (33 kg/ha 00.53), Harvest index (40.84%), were recorded. Higher gross returns (Rs. 1,48,295.14/ha), net return (Rs. 1,05,704.69/ha) and benefit cost ratio (2.48) were also recorded with this treatment combination.
