Abstract

An investigation was conducted on farmer’s field with an objective to study the “Residual effect of post-biomethanated spent wash on properties of soil solum and yield of Pearl millet” in the jurisdiction of Padmashri Vitthalrao Vikhe Patil Sahakari Sakhar Karkhana, Pravaranagar, Taluka-Rahata, Dist. Ahmednagar during 2007-08. Ten farmers from factory area of Pravaranagar and Gogalgaon village were selected, where spent wash was applied @ 70-75 m3 ha-1 before kharif season. Soil profiles were dug in the treated farms at harvest of the crop to study the residual effect of post biomethanated spent wash application on soil profile characteristics. The untreated fields were selected, adjacent to treated fields, where no spent wash was applied and were treated as control check to assess the effect of spent wash treated profiles in comparison to untreated soil profiles. The effect of spent wash application was assessed for pearl millet which was grown as test crop. The result revealed that post biomethanated spent wash was neutral in reaction with high concentration of soluble salt. The application of post biomethanated spent wash showed improvement in bulk density, hydraulic conductivity and water retention, while no residual effect on soil texture was observed. Slight build-up of salinity with distillery effluent application. The application of distillery effluent showed improvement in properties of soil. The Mean Weight Diameter (MWD), saturated hydraulic conductivity, water retention, field capacity and available water content were significantly higher, while bulk density (BD) and penetration resistance of the surface soil were significantly lower.
