Effect of sulphur and zinc on growth and yield of cowpea (Vigna unguiculata L.)

Abstract

A research trial was conducted at Crop Research Farm (CRF) of Department of Agronomy, SHUATS, Prayagraj, (U.P) in kharif season with an objective to check the response of sulphur and zinc on growth and yield of cowpea. Data of growth and yield characters of the crop were recorded. Randomized Block Design was implemented for the experiment with 10 treatments replicated thrice. The Treatments consisted of 3 levels of Sulphur (25, 30, 35 kg ha-1) and zinc (5, 10, 15 kg ha-1) with Cowpea var. Kashinidhi. The results reported application of Sulphur 35 kg ha-1 + zinc 15 kg ha-1 achieved highest plant height (58.6 cm), plant dry weight (34.11 g/plant), nodules/plant (25.9), pods/plant (17.1), seeds/pod (9.8), seed yield (1423.27 kg ha-1), stover yield (3201.9 kg ha-1), maximum gross returns (INR 1,06,745.14 /ha), net returns (INR 73,245.14 /ha) and Benefit Cost ratio (2.19) were attained in (T9) that is with 35 kg ha-1 Sulphur along with 15 kg ha-1 Zinc.
