Following the industrial revolution in the nineteenth century, agricultural machinery and tractors became available for tillage operations. Different types of tillage systems have different tillage depths and capacity to change soil physical properties that affect the crop yield and quality. Important soil physical properties such as bulk density, penetration resistance, water infiltration, hydraulic conductivity and soil compaction are affected by tillage. A study on the effect of various tillage methods on soil compaction was conducted during Rabi season of 2013-14 at village Ladwa, Hisar, Haryana (India). Experiment compared the yield, plant and soil parameters of no tillage and tillage with rotavator + subsoiler. Higher soil resistance was found in zero tillage (T1) as compared to treatment rotavator + subsoiler (T2). However, the soil resistance increased steadily after 30days after sowing (DAS) and 90 DAS and it almost approached the initial soil resistance level, as it was before tillage after 90 DAS. Higher infiltration rate was found in sub-soiler treatment because of the obvious reason. Better plant establishment have been found in the treatment where sub-soiler has been used due to better moisture availability, increased water infiltration rate and increased root growth. Since, many soil parameters were in favour of the treatment rotavator + sub-soiler (T2), significant increase in the yield was also found in treatment rotavator + sub-soiler (T2).
