The distillery spent wash contained all necessary elements and biofertilizer microbes (Rhizobia, Azospirilla, Azotobacter, and phosphobacteria) to support the growth of plants. Application of the spent wash, as it is without dilution, did not cause deformities and derangement of plant metabolism. The successful use of distillery spent wash as a liquid fertilizer for augmenting crop productivity in C3 and C4 plants has been demonstrated.
