EFFECT OF DISTILLERY INDUSTRY BYPRODUCTS ON NUTRIENT AND ENHANCED YIELD OF CUMBU NAPIER HYBRID GRASS

Abstract

Distillery spentwash is a nutrient rich liquid organic waste obtained from molasses based distillery industries after biomethanation process and it is the carrier of huge amounts of nutrients and organic matter. A field investigation was carried out during 2009 to 2010 at Research and Development Farm of M/S Bannari Amman Sugars Distillery Division Ltd, Ealur, Sathyamangalam, Erode to assess the performance of cumbu napier hybrid grass by utilizing distillery industry byproducts viz., distillery spentwash, biocompost and spentwash ash. Treatments involved are distillery spentwash @ 37.5 and 50 kilo litre per ha at full and split dose, biocompost @ 5.0 tonnes per ha and spentwash ash @ 400 kg per ha with recommended dose of fertilizers and the parameters were assessed at 12th , 26th , 39th and 52nd weeks after planting (1st, 3rd, 5th and 7th harvest). Results of the field experiment revealed that the application of spentwash @ 50 kilo litre per ha at full dose with recommended dose of nitrogen and phosphorus increased the quality parameters, nutrient parameters and green fodder yield over recommended dose of fertilizers.
