Abstract
Six genetically diverse varieties of wheat (Triticum aestivum L. em. Thell), viz., C-306, PBW-343, WH-283, WH-542, WH-147 and WH-711, were inoculated with two strains of Azotobacter chroococcum, namely, Mac27 and HT-54, to evaluate the differential response of wheat varieties to the inoculated strains on plant growth attributes under green house condition. Pot (filled with 5 kg sandy loam soil) experiment was conducted in completely randomized block design with three replications and three fertilizer treatments — 0 kg N ha–1, 90 kg N ha–1 and 120 kg N ha–1. Observations were recorded on individual plants for plant height, seed yield, total nitrogen content and total biomass. Variety C-306 showed best response towards both the strains of A. chroococcum. Strain Mac-27 showed better response as compared to HT-54.
