Abstract: A field experiment was conducted to assess the effect of tillage on soil physical properties and yield of soybean at agronomy farm Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during Kharif season of 2011-12. The experiment was laid out in randomized block design with five tillage treatments replicated four times. The tillage treatments constituted of conservation tillage (one harrowing by blade harrow), conventional tillage (one ploughing + one harrowing by tyne cultivator + one harrowing by blade harrow), very deep tillage (one subsoiler + one ploughing + one harrowing by tyne cultivator + one harrowing by blade harrow), shallow tillage by tractor (one tyne cultivator + one blade harrow), shallow tillage by bullock (one ploughing by MB plough + two harrowing by bakhar). The other intercultivation practices were kept common as recommended. Significant differences were observed for the soil physical parameters when various tillage treatments were compared with each other during the course of present investigation. The values of soil physical properties like dry bulk density, penetration resistance (cone index) were found to be the significantly lowest in very deep tillage treatment comprising of sub soiling. Similarly, the values of other physical parameter viz., soil porosity and hydraulic conductivity were increased to a level of significance in treatment where sub soiling was undertaken. The values of yield attributes and yield of soybean were increased in treatment of sub soiling as compared with other tillage treatments. Thus, it can be concluded that under the rainfed soybean with the package of tillage operations including one sub soiling + one ploughing +two harrowing can give the highest crop yield and improves the soil physical properties of Vertisols.
