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 “Effect of various tillage methods on soil compaction” was conducted during Rabi season of year 2013-14 at village Ladwa, Hisar, Haryana (India). Experiment compares the soil parameters for six tillage treatments no-tillage (T1), tillage with rotavator (T2), disc harrow(T3), Rotavator + subsoiler (T4), disc harrow + subsoiler (T5), power harrow (T6). The soil parameters like soil resistance, bulk density, moisture content and water infiltration rate were studied.Maximum soil resistance was found in zero tillage followed by disc harrow up to 150 mm soil depth. Minimum soil resistance was found in rotavator immediately after the tillage treatment. However, the soil resistance increased steadily after 30 DAS and 90 DAS and it almost approached the initial soil resistance level as it was before tillage after 90 days of sowing. Significant changes in bulk density also have been observed in treatment rotavator + subsoiler which substantiates the fact that this treatment has the minimum soil resistance. Minimum moisture loss has been registered in treatment no tillage and maximum was in power harrow. Water infiltration rate before the tillage treatment was 1.13 cm/minute in all the treatments and after the treatments the infiltration rate ranged between 1.19 to 2.72 cm/minute.
