Effect of Potassium and Boron on Growth, Yield and Economics of Cowpea

The treatments consist of Potassium (40, 50, 60 kg/ha) and Boron (0.6, 0.8, 1.0 kg/ha) along with control. The experiment was layout in Randomized Block Design with ten treatments each replicated thrice. Application of Potassium 60kg/ha and Boron 1.0kg/ha (treatment 9) in cowpea was recorded significantly higher Plant height (49.41cm), more number of nodules/plant (29.23), maximum plant dry weight (18.02g/plant), maximum no. of Pods/plant (15.4), seeds/pod (11.67), higher Test weight (21.83 g), Seed yield (1.26 t/ha), stover yield (3.62 t/ha), harvest index (35.29 %), higher gross returns (INR 63,000.00/ha), net return (INR 40,133.00/ha) and benefit cost ratio (1.76) was obtained in the treatment 9 [Potassium 60kg/ha + Boron 1.0kg/ha].
