Abstract

Three rhizospere bacterial strains were collected from chickpea and three strains found to be potential against Fusarium oxysporum and identified through 16s rRNA sequencing as Pseudomonas spp, E. cloacae and P. chlororaphis. The present study was conducted during 2019-2020 and 2020-2021 at Department of Molecular Biology and Genetic Engineering, RTMNU, Nagpur, Maharashtra, to evaluate the effects of PGPR with biocontrol activity on biochemical parameters under in vivo conditions in chickpea KWR-108 genotype under drought. The pooled data of two experiment results recorded T7 (A+B) PGPR treatment with consortium of Pseudomonas spp. and P. chlororaphis ranged highest in chlorophyll ‘a’ with 25.75 (mg/g). In chlorophyll ‘b’ highest recorded with 44.82 (mg/g) in T7 (A+B), whereas in total chlorophyll content highest ranged between 10.86 (mg/g) in T8 (A+C) with consortium of Pseudomonas spp. and E. cloacae. In carotenoid content, the highest value reported in T7 (A+B) with 36.21 (
