Influence of Zinc and Boron on Yield and Economics of Cowpea

“A field experiment was conducted at Crop Research Farm, Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Prayagraj, UP, during the autumn season of 2022 on sandy loam soil. The experiment was carried out in Randomized Block Design supplemented by Zinc (10, 15, 20 kg/ha) and Boron (1, 1.5, 2 kg/ha)”. The variety Kashi Nidhi was used and sown in July 2022. The results revealed that the crop supplemented with 20 kg/ha Zinc + 2 kg/ha boron increased significantly in yield parameters viz., no. of pods per plant (19.7), no. of seeds per pod (15.6), seed yield (1.28 t/ha) and stover yield (2.43 t/ha). This treatment also showed a positive effect on economics viz., gross returns (84029.00 INR/ha), net returns (56369.00 INR/ha) and B: C (1:2.03).
