Tillage one of the keystone land management practice which impinges soil ecology by altering soil physicochemical conditions. To scrutinize the modification soil physicochemical properties and microbial activity under different tillage systems, a trial was performed in an organically grown wheat crop for a time-lapse of two seasons (Rabi) 2017-18&2018-19 at student's research farm, Punjab agricultural university, Ludhiana. It encompassed three types of tillage systems alternating with paddy straw mulch (6t/ha). As it was a short-term study, the disparity in soil conditions among treatments was sparse, but treatments recorded statistically significant (p>0.05). Microbial counts (total viable count, Azotobacter count, and phosphate solubilizing microbial count) and phosphatases activity (acid and alkaline phosphatases) were pronounced in zero tillage supplemented mulch plots at 90 and 125 DAS (days after sowing). CT (conventional tillage), DT (Deep tillage) supplemented with mulch also recorded better microbial and phosphatase activity compared to control with the progression of first to the second year. Soil Electrical conductivity (E.C), available potassium and phosphorous declined with the concatenation of first to second year irrespective of tillage plots and growth stages. However, Soil texture, pH, were insignificant (p< 0.05). Altogether, it surmises that conservation agriculture conducive in the case of restoring soil health.
