The present study was based on two experiments: one carried out in pot under natural condition and other carried out in field. In potted plant the effects PGPRs and Rhizobium leguminosarum have been studied on the growth, yield parameters and N2 fixation of chickpea under natural condition. Kinetin was found to be the most affective in increasing growth parameter and nitrogen fixation of chickpea. Application of Rhizobium inoculum, generally increased growth yields components and Nitrogen fixation. The pattern of response to hormone and Rhizobium inoculum was consistent in the three consecutiv...
The present study was based on two experiments: one carried out in pot under natural condition and other carried out in field. In potted plant the effects PGPRs and Rhizobium leguminosarum have been studied on the growth, yield parameters and N2 fixation of chickpea under natural condition. Kinetin was found to be the most affective in increasing growth parameter and nitrogen fixation of chickpea. Application of Rhizobium inoculum, generally increased growth yields components and Nitrogen fixation. The pattern of response to hormone and Rhizobium inoculum was consistent in the three consecutive years. It would suggest that that both the efficiency and the longevity of the nodules favorably affected by kinetin application. A three-year chickpea-wheat rotation study in fields was carried in a well-drained sandy soil to quantify nitrogen fixation by chickpea and determine its residual N effects on soil N-fertility and yield of following wheat crop. Continuous chickpea crop and its rotation with wheat enhanced N fertility level of the soil. Our results support the strategy of using legumes in rotation with wheat in the arid region forenhancing soil N-supply and increasing wheat yield.
