Abstract: 

A pot experiment was conducted to evaluate the effect of soil and lignite mine effluent, both were already treated with the bacterial consortium (Bacillus subtilis + Pseudomonas stutzeri + Pseudomonas alcaligenes), on growth and yield of paddy (ADT-36). Paddy cultivated on bioremediated soil irrigated with biologically treated effluent showed increased growth rate viz., plant height (67.2 cm), the number of tillers/hill (13.50) and total leaf area (60.02 cm2 /plant). Yield attributing values of paddy plant were also higher in treated soil irrigated with biologically treated effluent. Higher levels of chlorophyll (1.620 mg/g fr.wt)), starch (7.798mg/g fr.wt in root, 12.099 mg/g fr.wt in shoot) and amino acids (0.590 mg/g fr.wt,in root, 0.394 mg/g fr.wt.in shoot)content were also recorded. These values were lower in the paddy, cultivated in untreated soil irrigated with raw effluent.
