Description This dataset contains, field trials were conducted for two cropping seasons in 2012–13 and 2013–14 at ICRISAT, Patancheru. The experiment was laid out with three replicates and sub-plot sizes of 4 x 3 m rows in ridges in a randomized complete block design (RCBD) under irrigated condition. The Streptomyces strains (CAI-13, CAI-85, CAI-93, CAI-140, CAI-155 and KAI-180) were grown individually on starch casein at 28°C for 4 to 5 days. Seeds of Chickpea variety ICCV 2 (duration 90 days) were treated individually with a Streptomyces strain (108 CFU per ml) for 45 min and hand sown on Oct 2012 in the first year and Nov 2013 in the second year Streptomyces strain was applied once in 15 days, from the sowing day, on the soil close to the plant until the flowering stage. The Chickpea crop was harvested manually. Samplings were done at 30 DAS, 60 DAS and at crop maturity. On the sampling day, plant underground and aerial parts were harvested separately with care to eliminate border effects in each plot. During both the seasons of 2012–13, 2013–14, Chickpea growth performance was measured in terms of nodule number, nodule weight, root weight and shoot weight at 30 DAS; plant height, pod number, pod weight, leaf area, leaf weight and stem weight at 60 DAS; and stover yield, grain yield, total dry matter (TDM), 1000 seed weight, pod weight, seed number and seed weight at crop maturity. Also, at crop maturity, rhizosphere soil samples were collected from top 0 to 15 cm soil and analysed for total nitrogen, available phosphorous, organic carbon, microbial biomass carbon and dehydrogenase activity.
