In field experiments (1991 and 1992) with soybean under rainfed condition on Vertisol, seed, total dry matter yields and phosphorus contents in different plant parts at various stages increased with the use of Pseudomonas striata alone and in conjunction with superphosphate and rock phosphate. Seed treatment with P. striata inoculant further enhanced the yields and phosphorus content (%) of soybean when applied in conjunction with phosphate fertilizers but maximum increase and P content was with rock phosphate as compared with superphosphate.
