Abstract
Rhizobium is well known nitrogen fixer and Pseudomonas is known for Biological control. In present study screen the impact of co-inoculation of Pseudomonas and Rhizobium strains on seed germination, seedling plant height and seedling biomass of Maize plant. Twenty–twenty Plant growth promoting Rhizobium and Pseudomonas were selected for present study. Interaction study of Rhizobium and Pseudomonas were analysed. Only Pseudomonas PSB2, Pseudomonas PSB17, Rhizobium RSB4, Rhizobium RSB16 did not inhibit growth of each other. Therefore, they were selected for pot experiment. Nine treatments such as Treatment 1: Pseudomonas PSB2, Treatment 2: Pseudomonas PSB17, Treatment 3: Rhizobium RSB4, Treatment 4: Rhizobium RSB16, Treatment 5: Rhizobium RSB4 + Pseudomonas PSB2, Treatment 6: Rhizobium RSB16 + Pseudomonas PSB2, Treatment 7: Rhizobium RSB4 + Pseudomonas PSB17, Treatment 8: Rhizobium RSB16 + Pseudomonas PSB17, Treatment 9: Control (without bacteria) were prepared for pot experiment. Results suggested that all bacterized enhanced seed germination and plant growth parameters such as root length, shoot length, root weight and shoot weight. Maximum root length and shoot length was observed in co-inoculation of Rhizobium RSB4 + Pseudomonas PSB2 by 83.87, 60.71% more as compared to control. We concluded that co-inoculation of Rhizobium and Pseudomonas improves plant growth activity in Maize.
