Abstract:

A long-term field experiment was carried out in alluvial soil with conservation agriculture practices like Zero tillage (ZT), Permanent bed (PB) and Conventional tillage (CT) to see the impact on Physico-chemical Properties of soil under rice based cropping systems. After completion of 7th cycle of experiment (2018), soil samples were collected from each plot and analysis processes were executed. The results obtained from the study show that the conservation agricultural practices increased the organic carbon 0.47 to 0.71%, cation exchange capacity 9.76 to 13.04 [cmol (p+) kg-1], available-N 150.52 to 175.67 kg/ha available P2O5 150.52 to 175.67 kg/ha, available K2O 202.40 to 245.63 kg/ha and available S 14.66 to 22.84 mg/kg of soil. It was further observed that after 7 years of experimentation, a build-up of organic carbon upto 30% (0.69%) and 26% (0.67%) from the initial value (0.53%) due to zero tillage and permanent bed respectively were observed. Among the cropping systems, Rice-Lentil system sustained the soil physico-chemical properties to a greater extent compared to Rice-Wheat and Rice-Maize systems. Retention of crop residue and minimum disturbance of surface soil under conservation agriculture increases the organic matter content leading to enhanced crop nutrition and sustain the soil health.
