Abstract:

Use of nitrogen fixing and phosphate solubilizing microorganisms (biofertilizers) has become an important aspect of pulse crops production technology. The efficiency of these microorganisms differs widely in accruing the benefits of their application in crops. Ten Mesorhizobium isolates having various plant growth promoting (PGP) traits including phosphate solubilization were screened for their symbiotic efficiency in terms of root nodulation, plant dry matter production, nitrogen and phosphorus content and nitrogen fixation by chickpea plant in a field experiment during 2015-16. The isolates showed considerable variations in the symbiotic performance by producing nodule number from 17.3 to 21.8 plant-1, nodule dry weight from 68.0 to 76.1 mg nodule plant-1 and plant dry weight from 2.74 to 3.53 g plant-1 at 60 DAS registering significant increases over the uninoculated control. The shoot and root length at 60 DAS due to inoculation of different isolates also varied significantly and were higher than the uninoculated control. The different isolates accumulated 92.8 to 127.1 mg more nitrogen plant-1 indicating fixation of 34.3 to 68.6 mg nitrogen plant-1 over the native population at 60 DAS. Mesorhizobium isolate CR-53 was found most promising and followed by the isolates CR-3 and CR-40 in symbiotic performance, nitrogen accumulation and fixation in chickpea. The results suggested that Mesorhizobium isolates having different PGP traits could be a better option for obtaining the benefits of inoculation and improving pulse production.
