Influence of Phosphorus Levels on Green Fodder Yield and Quality of Fodder Cowpea Genotypes

Abstract

A field experiment was conducted to assess the impact of phosphorus levels viz., 30, 60 and 90 kg/ha on the performance of diverse genotypes of fodder cowpea viz., MFC 08-14, IL-1177, UPC-9202, UPC-5286 and Bundel Lobia-1 under advance varietal trial during kharif season, 2012. The genotype IL-1177 recorded a maximum green fodder yield of 28.2 t/ha which is 16.7 % higher than UPC-9202, 13.5% higher than UPC-5286 and 6.7% higher than Bundel Lobia-1. Application of 90 kg P 2 O 5 /ha had strikingly enhanced the green fodder yield to 27.0 t/ha. Cowpea genotype IL-1177 with application of 90 kg P 2 O 5 /ha was found to be profitable.
