EFFECT OF PHOSPHORUS, SULPHUR AND PHOSPHATE SOLUBILIZING BACTERIA ON YIELD COMPONENTS, YIELD AND QUALITY OF CLUSTERBEAN [CYAMOPSIS TETRAGONOLOBA (L.) TAUB.]*

A field experiment was conducted during the rainy (kharif} seasons of 1999 and 2000 on loamy sandsoil. Theapplication of 30kg P205ha−1 significantly increased the number of podsperplant, seed per pod, length of pod, test weight, seed yield, straw yield, biological yield, gum yield, protein content in seed and straw, total uptake of N, P and S. The pods per plant, seeds per pod, protein content, gum yield and total uptake of N, P, and S significantly increased up to 60 kg S ha−1 whereas the length of pod and test weight increased significantly upto 40 kg S ha−1. The seed inoculation with PSB significantly increased all the yield components. seed and straw yield, biological yield, protein content in seed and straw, gum content and total uptake of N. P and S over the uninoculated control. The seed yield was found to be significantly and positively correlated with yield components and total uptake of N, P, and S.
