Effect of Bioinoculents on Growth, Yield and Fibre Quality of Cotton under Irrgation

Field experiment was conducted at Marathwada Agriculture University, Parbhani (M.S., India) to study the effect of bioinoculents on cotton. A co-cultured formulation of Azospirillum, Phosphorus solubilizing bacteria (PSB) and Pink Pigmented facultative methylotrops (PPFM) was used as bioinoculants in cotton. Plant Growth Parameters of shoot and root, Yield Parameters and fibre quality parameters were determined. Better growth and high yield of cotton was obtained by using bioinoculents. Inoculation of Azospirillum, PSB and PPFMs along with chemical fertilizers resulted in to the significant increase in growth parameters of cotton. The superiority of Surat strain of Azospirillum + PSB + PPFM was evident at all the fertilizer level. The uses of bioinoculents are beneficial in improving the fibre quality up to some extent.
