Isolation, identification and screening of Rhizobium for plant growth promotion
The Rhizobium was isolated from the root nodules of groundnut plant using YEMA medium and identified. Then the Rhizobium was screened on the basis of pH resistance, temperature resistance, salinity resistance and antibiotic resistance. The plant growth promotion by Rhizobium was studied by Leonard jar experiment. The seeds of cowpea plants were treated with various concentration of Rhizobium culture at different time intervals. After the growth period, the plants were subjected for root length, shoot length, count of root nodules formed and chlorophyll content. The plants of T-4 (Treatment-4) showed better results than the other treatments.
