Abstract

Interaction between Azospirillum brasilense and the 'phosphate solubilizing bacteria' Pseudomonas striata and Bacillus polymyxa, and their influence on yield, nutrient uptake and acetylene reduction activity of sorghum were studied in a sandy loam alluvial soil under greenhouse conditions. Results showed a significant increase in the yield level of sorghum due to combined inoculation over single inoculation indicating a positive interaction between the 2 groups of bacteria. The yields were further enhanced markedly by the application of 40 kg N as urea and 60 kg P2O5/ha as rock phosphate together with inoculation treatments over fertilizer alone or inoculation without fertilizers. The possibilities of saving 40 kg N and replacing the entire quantity of superphosphate with rock phosphate plus inoculation of A. brasilense and P. striata or B. polymyxa together are discussed
