Cultivation of cerealrnforages namely; Maize (Zea mays), Bajra (Pennisetum Glaucum) and Oats (Avenarnsativa) was made by irrigation with distillery spentwash of differentrnproportions. The distillery spentwash i.e., primary treated spentwash (PTSW),rn1:1, 1:2 and 1:3 distillery spentwash were analysed for plant nutrients such asrnnitrogen, phosphorous, potassium (NPK) and other physical and chemicalrnparameters. The plants were cultivated by irrigation with raw water (RW), 1:1,rn1:2 and 1:3 distillery spentwash in the prepared pots. The impact of distilleryrnspentwash on proximate principles for quality forage (Crude protein, Neutralrndetergent fibre, Acid detergent fibre and Total digestible nutrient) i.e.,rnforage digestibility for livestock were analysed. It was observed that goodrnnutrients uptake in case of 1:3 spentwash and requirements of livestockrndigestibility components were observed when compared with 1:1, 1:2 spentwashrnand raw water irrigations. This could be due to the maximum absorption of NPKrnby plants at more diluted condition of spentwash. This concludes that therndiluted spentwash can be conveniently used for the effective cultivationrnwithout using any external fertilizers. Hence, spentwash serves as a liquidrnfertilizer, eco-friendly irrigation medium and without adverse effect onrnenvironment and soil.
