In kharif 2022, a field experiment was conducted at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (UP) to determine the “Effect of Phosphorus and foliar application of iron and zinc on growth and yield of cowpea (Vigna unguiculata L.).”  The findings showed that treatment-9 (Phosphorus 75 kg/ha + Fe-0.5 % + Zn-0.5 %)  significantly increased plant height (75.57 cm), plant dry mass (17.66 g/plant), crop growth rate (5.97 g/m2/day), higher number of pods/plant (14.76), higher number of seeds/pod (10.52), seed yield (1.25 t/ha), stover  yield (2.81 kg/ha), gross  return (79,219.00 ₹/ha), net return (54,092.46 ₹/ha) and also, the maximum B:C ratio (2.15) was taken captive in treatment-9 (Phosphorus 75 kg/ha + Fe-0.5 % + Zn-0.5 %) in comparison to different treatments.

Keywords    Cowpea, Phosphorus, Iron, Zinc, Growth parameters, Yield attributes, Economics.
