Impact of distillery spentwash irrigation on the production of quality additive graminacious forage crops on livestock digestibility

Author(s): S Chandraju, Bhuvan P
Abstract: Graminacious forages namely; Napier Grass (Pennisetum Purpureum Schumach), Guinea Grass (Panicum Maximum Jacq) and Signal Grass (Brachiaria Brizantha) were cultivated and irrigated with distillery spentwash of different proportions. The distillery spentwash i.e., primary treated spentwash (PTSW), 1:1, 1:2 and 1:3 distillery spentwash were analysed for plant nutrients such as nitrogen, phosphorous, potassium (NPK) and other physical and chemical parameters. The plants were cultivated by irrigation with raw water (RW), 1:1, 1:2 and 1:3 distillery spentwash in the prepared pots. The impact of distillery spentwash on proximate principles for quality forage (Crude protein, Neutral detergent fibre, Acid detergent fibre and Total digestible nutrient) i.e., forage digestibility for livestock were analysed. It was observed that good nutrients uptake in case of 1:3 spentwash and requirements of livestock digestibility components were observed when compared with 1:1, 1:2 spentwash and raw water irrigations. This could be due to the maximum absorption of NPK by plants at more diluted condition of spentwash. This concludes that the diluted spentwash can be conveniently used for the effective cultivation without using any external fertilizers. Hence, spentwash serves as a liquid fertilizer, eco-friendly irrigation medium and without adverse effect on environment and soil.
