Abstract

Combined inoculation of Rhizobium and ‘Phosphate-solubilizing’Pseudomonas striata orBacillus polymyxa with and without added chemical fertilizer on chickpea yield and nutrient content was studied under greenhouse conditions. While the single inoculation of Rhizobium increased the nodulation and nitrogenase activity, the ‘phosphate-solubilizers’ increased the available phosphorus content of the soil. Combined inoculation of Rhizobium andP. striata orB. polymyxa increased the above parameters and also the dry matter content, the grain yield and nitrogen and phosphorus uptake significantly over the uninoculated control. The inoculation effects were more pronounced in the presence of added fertilizers. The possibilities of saving half the dose of N and replacing superphosphate with rockphosphate and inoculation with ‘phosphate-solubilizers’ are discussed.
