Abstract A field experiment entitled “the yield performance of soybean and its economics under different tillage practices” was conducted at Research Farm, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during kharif season of 2013–14. Soil was clayey in texture with high amount of potash (337 kgha−1) and moderate in phosphorus (18.44 kg ha−1) and low in nitrogen (194 kg ha−1), slightly alkaline in nature. The experiment was laid out in randomized block design with five tillage treatments replicated four times. The tillage treatments constituted of (1) Zero tillage, (2) Conventional tillage (one ploughing+one harrowing by tyne cultivator+one harrowing by blade harrow), (3) Very deep tillage (one subsoiler+one ploughing+one harrowing by tyne cultivatior+one harrowing by blade harrow), (4) Shallow tillage by tractor (one tyne cultivator+one blade harrow), (5) Shallow tillage by bullock (one ploughing by MB plough+two harrowing by bakhar). The net plot size was 9.6 m x 9.6 m. Sowing of soybean (var. JS-335) was undertaken during 28th June, 2013. The other intercultivation practices were kept common as recommended, except at Zero Tillage, where no intercultivation was carried out. It is revealed that the values of plant growth, yield attributes and yield of soybean were significantly increased with treatment of subsoiling+ploughing+two harrowing as compared to other tillage treatments. The yield increase due to subsoiling+ploughing+two harrowing over zero tillage treatment was to the tune of 77%. Significantly highest values of gross monetary returns (GMR), net monetary returns (NMR) and benefit cost ratio (B.C) were recorded with very deep tillage treatment consisting of subsoiling+ploughing+two harrowing.
