Abstract
A field experiment was conducted during Kharif 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The treatments consist of three levels of zinc and three levels of boron and one control was used. The experiment was laid out in Randomized Block Design with ten treatments each replicated thrice. The results showed that growth parameters viz., plant height (116.77 cm), number of tillers per hill (31.13), dry weight (106.07 g/hill) and yield attributes viz., number of effective tillers per hill (9.53), number of filled grains per panicle (129.33), test weight (15.87 g), grain yield (5.57 t/ha) straw yield (8.77 t/ha) and harvest index (38.44 %) were recorded significantly higher with the application of zinc 15 kg/ha along with boron 6 kg/ha. Maximum gross returns (155166.77 INR/ha), Net returns (102889.22 INR/ha) and benefit cost ratio (1.97) were also recorded in treatment-9.
