Effect of Biomethanated Distillery Spentwash on Quality and Nutrient parameters of Maize Grown on Entisol

Abstract

A field Experiment was carried out during 2009 in the farmer’s field at Sathyamangalam, Erode with the objective to assess the effect of liquid distillery effluent as irrigation water on grain quality (reducing sugars, protein and starch) and nutrient uptake (N, P, K Ca, Mg, Zn, Cu, Fe and Mn) of maize. Treatments consisted of 50, 100 and 150 kilo l per ha of the biomethanated distillery spentwash along with recommended dose of fertilizers with and without potassium. Results of the field experiment revealed that the application of biomethanated distillery spentwash @ 100 kilo l per ha with recommended dose of NPK or NP (without K) significantly increased the grain protein content and nutrient uptake of maize over recommended dose of fertilizers.
