Quality and economics of cowpea as influenced by genotypes, phosphorus levels and liquid based PSB

Abstract

A field experiment was conducted to evaluate the quality and economics of cowpea genotypes to phosphorus levels and liquid based PSB during kharif 2019 under rainfed condition at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad. Among the genotypes, the genotype DC-15 recorded significantly higher seed protein content, protein yield and B:C ratio (23.84%, 292.50kg ha-1 and 2.11, respectively) over other genotypes. Whereas, the application of 75 kg P2O5 ha-1 + liquid PSB @ 4ml kg-1 seeds recorded significantly higher seed protein content, protein yield and B:C ratio (23.81%, 320.54 kg ha-1 and 2.27, respectively) over other phosphorus levels. Among the interactions, DC-15 with the application of 50 kg P2O5ha-1+ liquid PSB @ 4ml kg-1 seeds recorded significantly higher seed protein content (25.10%)over the control and other treatments. The percent increase in seed protein was 17.95% over the control.Further, the genotypeDC-15 with the application of 75 kg P2O5ha-1+ liquid PSB @ 4ml kg-1 seeds recorded significantly higher protein yield and B:C ratio (351.22kg ha-1 and 2.47)over the control and other treatments.
