Effect of biogas digest on soil physicochemical properties under chickpea cultivation in clayey soils

Abstract

A field experiment was conducted during Rabi, 2018 in clayey soils, at Agricultural College Farm, Bapatla, to study the ‘Effect of biogas digest on soil physico chemical properties under chickpea cultivation in clayey soils. Reduction in pH & Electrical conductivity (EC) of the soil was observed at all the stages of the crop with the application 100 per cent recommended dose of phosphorus (RDP) through biogas digest along with microbial consortium (T10). Significantly higher soil organic carbon of 0.91, 0.86 & 0.72 g kg-1 was recorded at vegetative, reproductive and harvest stages of the crop with T10 and application of 100 per cent RDP through biogas digest (T9). The cation exchange capacity (CEC) and percent base saturation is also recorded superior in application of organic manures and microbial consortium over other treatments.
