Abstract: Tillage by effecting soil conditions through manipulating its physical and chemical properties and influencing the availability of nutrients. Traditional practices are intensive tillage that leads to a negative impact on crop productivity and soil properties. Conservation agriculture including tillage reductions, better agronomy, and improved varieties, showed positive result on soil and plant health. Higher yield of crops reported under furrow irrigated raised bed (FIRBS) system followed by no tillage (NT) and conventional tillage (CT). Tillage practices may also influence the distribution pattern of soil organic carbon (SOC). It was observed higher SOC concentration in the surface layers in no tillage than conventional tillage. Zero tillage (ZT) treatment showed significantly higher macro and micronutrient levels in their available form than the other treatments. Mostly researchers reported higher dissolve organic carbon (DOC) under conventional tillage over the conservational tillage. Humus content was significantly affected by different tillage practices and reported higher under ZT and RT.
