Under laboratory conditions, sterilized OIW (a problematic waste of oxalic acid industries of Madhya Pradesh) allowed Rhizobium to multiply at both the temperatures (ambient, i.e. ranging from 7.5 to 30°C during the course of studies and 40°C) up to 90 days as compared with lignite. Nodular mass, grain yield and nitrogen content of shoot of soybean were also substantially increased by the bioinoculant developed from sterilized OIW.
