Abstract

                                A field experiment was conducted during 2009 to 2011 at Research and Development farm, M/s. Bannari Amman Sugars Distillery Division Ltd., Ealur, Erode to assess the performance ofcumbu napier hybrid grass by utilizing distillery industry byproducts viz., distillery pentwash,biocompost and spentwash ash. Treatments involved are distillery spentwash @ 37.5 and 50kilo l 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 cuttings). Results of the field experimentrevealed that the application of distillery spentwash @ 50 kilo l per ha at full dose with recommend dose of nitrogen and phosphorus increased the physiological parameters, green fodder yield and soil biological properties and decreased the biochemical parameters over recommended dose of fertilizers.
