Abstract: Field experiments were conducted to assess the optimum dilution of Post Methanation distillery Effluent (PME) to utilise as an organic nutrient source for growing rice and wheat crops. Dilution levels of distillery effluent significantly affected the biomass production as well as grain yield of rice and wheat crops. Levels of organic carbon and NPK were significantly higher in effluent treated soils. The crop performance and yield with distillery effluents alone were overall less than that produced by distillery effluents with chemical fertilisers, probably on account of failure of the effluents to supply balanced nutrition to the plants for achieving their potential growth capacity.
