Effect of plant growth-promoting Streptomyces sp. on growth promotion and grain yield in chickpea (Cicer arietinum L).

ABSTRACT: The physiological and molecular responses of six strains of Streptomyces sp. (CAI-13, CAI-85, CAI-93, CAI-140, CAI-155 and KAI-180), with their proven potential for plant growth-promotion (PGP) in rice were studied to understand the mechanisms causing the beneficial effects. In this investigation, those six strains were evaluated for their PGP capabilities in chickpea in the 2012-13 and 2013-14 post-rainy seasons. All of the Streptomyces sp. strains exhibited enhanced nodule number, nodule weight, root weight and shoot weight at 30 days after sowing (DAS) and pod number, pod weight, leaf area, leaf weight and stem weight at 60 DAS in both seasons over the un-inoculated control. At chickpea crop maturity, the Streptomyces strains had enhanced stover yield, grain yield, total dry matter, pod
