Abstract
Field experiment was conducted during 2009 (August to December) in the Research and
Development farm of M/s. Bannari Amman Sugars Distillery Division Ltd., Ealur, Erode to find
out the optimum dosage of biomethanated distillery spentwash (BDS) and its effect on soil
fertility and yield of maize. Different doses of BDS along with inorganic chemical fertilizers
were assessed in maize (cultivar COH (M) 5). The soil nutrient parameters viz., pH, EC, organic
carbon, exchangeable cations and macro nutrients were estimated at vegetative, flowering
and post harvest stages along with and dry matter production, cob, grain and stover yields
of maize. The results of the field experiment revealed that the application of BDS @ 100 kilo l
per ha with recommended dose of NPK significantly increased the soil nutrient availability
and yield parameters of the maize crop over recommended dose of fertilizer control.
