Abstract
Zinc (Zn) is an important element of thousands of proteins in plants, but excessive amounts are poisonous. It can be employed for catalytic, regulatory, and structural activities in cocatalytic sites (for example, superoxide dismutases, purple acid phosphatases, and metallo—lactamases). Cowpea (Vignaunguiculata L), a member of the fabaceae family, is a robust crop produced primarily in semi-arid regions ,also both in tropical and subtropical areas as a source of vital protein .In its strategic growing locations, it has enormous sociocultural and economic significance. Because of its great nutritional value and accessibility to the poor, it is also known as poor man's meat, and it serves as a cornerstone in guaranteeing food security. To achieve the goal of the study, a pot experiment was conducted in the net house of the Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, to gauge and analyse the ‘Effect of Zinc Application on Growth, Yield, and Quality of Cowpea in Zinc Deficient Soil'. Bulk of soil samples were taken from zinc deficient location in Uttar Pradesh's Narayanpur block of Fattepur village and cowpea crop was planted in 2020 with varying doses of zinc and RDF (60:30:30) comprising of nine treatments, replicated thrice with the goal of evaluating growth parameters in response to zinc application. Zinc in soil has a practical impact on nutrient transformation, metabolism, and use in cowpea. Based on the results of the experiment, it was inferred that the effect of soil application of Zn @ 7.5 mg kg-1 (T7) in the trial was most successful in producing higher growth and yield attributing features in cowpea beyond which it adversely affected the yield and growth parameters.
