Abstract:
The aims of our study were to enhance growth, yield and disease control of chickpea by various combinations of microbial strains (Mesorhizobium, Azotobacter chroococcum, Pseudomonas aeruginosa and Trichoderma harzianum). Pseudomonas and Trichoderma showed positive IAA (indole-3-acetic acid) production, phosphate solubilisation and antagonistic activities against Fusarium oxysporum and Rhizoctonia solani as compared to other strains. In two year investigations, tetra-inoculants have shown significant growth attributes, yield and phytopathogen growth inhibition followed by tri-inoculants than control. Therefore, tetra-inoculants (Mesorhizobium-Azotobacter-Pseudomonas-Trichoderma) may be used as efficient biofertilizer and bio-control agent for chickpea production (Cicer arietinum L.) in eastern Uttar Pradesh.
