Abstract

Cowpea [Vigna unguiculata (L.) is the most widely cultivated pulse crop of India. Deficiencies of micronutrients viz., Zn and B are a common problem in cowpea. Foliar Application is very effective to correct the micronutrient deficiencies in pulses, but it is too laborious. The Present Research was held at Research Farm, Department of Soil Science and Agricultural Chemistry, SHUATS, Prayagraj a field experiment was undertaken in the Zaid season 2021, With 9 treatments and 3 replications, the experiment was set up in a Randomized Block Design (RBD) results includes, the physico-chemical properties ranged optimum range and the available Zinc was found 0.46 to 0.38 in 0-15 mg kg-1 cm depth and 0.33 to 0.23 mg kg-1 in 15-30 cm depth. Available Boron was found 0.62 to 0.53 mg kg-1 in 0-15 cm soil depth and 0.36 to 0.29 mg kg-1 in 15-30 cm depth. Post-harvest available Zn and B content registered lower. This might be due to the antagonistic effect of Zn on B. And may be attributed to the fact that by the foliar application at 4th and 6th week, maximum nutrient was readily used up by the plant parts.
