摘要： Aims: the sugar mill based distillery effluent has become a challenge for environment protection. It is necessary to deal with this effluent eco-friendly and cost-effectively. Methods and results: The sugar mill based distillery effluent was used to mix with other fertilizers to form liquid fertilizer, which was applied to sugarcane. The experiment was conducted in randomized block arrangement with three duplications. The rates of the liquid fertilizer were 7.5t/ha, 15t/ ha and 22.5t/ ha, which increased the yield of the sugarcane by 2.4t/ha, 5.915t/ha and 7.543t/ha respectively with rate of growth of 3.29-10.34%, and increased the yield of sugar by 0.99t/ha, 1.165t/ha and 1.368t/ha respectively with rate of growth of 10.18-14. 07%. The economic benefit from applying the liquid fertilizer to sugarcane was very significant. It should be an effective approach to address the sugar mill based distillery effluent to apply directly the liquid fertilizer made from effluent on sugarcane field provided thetransportation issue can be tackled well. Significance of the Study: Using the distillery effluent as fertilizer resource, Liquid fertilizer changes the waste into valuable use. Application of liquid fertilizer can increase soil organic matter, improve soil physical and chemical characteristics, upgrade soil fertility, and it is helpful for building good soil ecosystem and sustainable sugarcane production.
