ABSTRACT

​

A field experiment was conducted during Zaid 2022, at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (UP). The treatments consist of three levels of potassium and three levels of zinc 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 (208.6 cm) and dry weight (34.3 g/plant) were recorded significantly higher with the application of 50 kg K/ha and 15 kg Zn/ha and yield attributes viz., ear head length (24.7 cm), number of grains per ear head (2498.3), grain yield (3.93 t/ha), straw yield (7.78 t/ha) and harvest index (50.4 %) were recorded significantly higher with the application of 50 kg K/ha and 15 kg Zn/ha. The maximum gross returns (₹98,250/ha), net returns (₹70,656/ha) and benefit cost ratio (2.56) were gained with the application of 50 kg K/ha and 15 kg Zn/ha.
