Abstract

The field experiment was conducted during kharif 2020 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj, Uttar Pradesh, to study the response of plant growth regulators and micronutrients on growth, yield of Cowpea (Vigna unguiculata L.). The treatments consist of seven plant growth regulators (Superzyme gold, Root master. Superzyme, Boost, Americana, Sea bomb) and one micronutrient (Microl-F), and one respective control was used. The Experiment was designed in Randomized Block Design consists of eight treatments each replicated thrice. It was observed that T3 Superzyme 900 ml/ha foliar spray at 25 and 45 Day after sowing was recorded as best treatment for obtaining growth and yield attributes such as plant height (122.72 cm), number of branches per plant (5.90), pods per plant (11.60), seed yield (903.03 kg/ha), stover yield (1423.33 kg/ha). While net returns (90,514.50 INR/ha) and B:C ratio (2.0) were also observed with the application of Superzyme 900 ml/ha foliar spr
