ABSTRACT

The aim of present study was the production of liquid nitrogen fixer biofertilizer using selective and optimized media. Nitrogen containing products which helps to increase germination rate, increase production rate with growth of plants. Field inoculation of plants with Azotobacter and Rhizobium after cultivation of experimental plants it is noted that 20-40 kg nitrogen remain back which benefits for further plantation and reduce use of 25 % chemical fertilizers. Due to the function of Azotobacter and Rhizobium in nitrogen fixation and to their probable biotechnological applications, there are few challenges in developing an effectual approach for the selective isolation of these micro-organisms from soil. During this study experimental plants of chickpea Cicer arietinum shows that the growth of plant is better than normal growth and it increase yields.
