Abstract

A field experiment was conducted during Zaid season (March to June; Summer season crop) of 2022 at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj, Uttar Pradesh, India to determine the “The effect of phosphorus and molybdenum on the growth and yield of summer Cowpea (Vigna unguiculata L.)”. The results showed that the treatment 9 [Phosphorus (50 kg/ha) + Molybdenum (2 kg/ha)] recorded significantly higher plant height (73.43 cm), higher number of nodules per plant (17.66), higher plant dry weight (23.07 g/plant), higher crop growth rate(18.87g/m2/day) maximum number of pods per plant (15.10), maximum number of seeds per pod (14.67), higher seed index (16.03 g), higher seed yield (1550.27 kg/ha) and   higher stover yield (1615.50 kg/ha) and higher harvest index (49.05%) was recorded in  treatment 8 [Phosphorus (50kg/ha) + Molybdenum (1.5kg/ha)]. Similarly, maximum gross return (94954.8 INR/ha), higher net return (65670.3 INR/ha) and highest Benefit Cost ratio (2.24) was also     recorded in treatment 9 [Phosphorus (50kg/ha) + Molybdenum (2kg/ha)] as compared to other treatments.
