Varitel response of wheat azospirillum spp
Soil samples from ten villages in Pravara area (Tahasil Rahata Dist.Ahmednagar) were collected. From these localities ten different strains of Azospirillum were isolated, purified and were labeled as A1,A2,—-A10.These strains individually and in mixed combination were further treated to wheat varieties viz HD2189,Mohan wonder,496, Trimbak and 2123.Sowing of seeds was done in 1×1 sq.m field plot at row spacing 22.5 cm in Randomize Blok Design. Crop productivity was measured interm of height, number of tillers and number of leaves. Out of ten strains, A2, A4, A5, A6 individually proved significantly effective over the control, however A2+A4+A6 strain combinations was proved highly significant over the control and individual strain for the growth and development in all wheat varieties. Variety HD2189 was showed significant response to mixed combination over the other verities.
