Effect of Phosphorus on Cowpea (Vigna unguiculata L. Walp): A review

Abstract

Genotypes and phosphorus levels of other legume crops were also studied and included in the review. It has been seen that plant height of cowpea increased with application of 40 kg P2O5/ha and 90kg P2O5/ha. 40 kg P2O5/ha and 80 kg P2O5/ha recorded significant increased on number of branches per plant. Number of leaves per plant, dry matter accumulation and days to first flowering is enhanced by 90kg P2O5/ha, 60 kg P2O5/ha and 40 kg P2O5/ha respectively. However cowpea different yield attributes are influenced by 75 kg P2O5/ha, 60 kg P2O5/ha, 50 kg P2O5/ha, 60 kg P2O5/ha, 70 kg P2O5/ha, 80 kg P2O5/ha and 30 kg P2O5/ha with substantial increase in the growth of different parameters respectively. Hence, application of phosphorus equally influences the growth and yield components of cowpea genotypes.
