STUDY OF DIFFERENT TILLAGE TECHNIQUES UNDERSOYBEAN-WHEAT CROP ROTATION IN CONSERVATION AGRICULTURE

Under conservation agriculture besides conservation tillage (no-tillage and minimum tillage, at least 30% of the previous crop residue on the soil are maintained under regular crop rotation. Experiment was conducted during Kharif and Rabi season at the research farm of Central Institute of Agricultural Engineering, Bhopal in Madhya Pradesh on soybean-wheat crop rotation. In this regards, the operation wise selection of different animal drawn implements under no tillage and minimum tillage practice were made and compared to traditional practice for soybean and wheat crop. The productivity of conventional tillage and minimum tillage was found at par for wheat crop. Conservation agriculture with no-tillage practice saved 20% in cost and 12% energy as compared to conventional tillage. Benefit of conservation agriculture requires to be ascertained by conducting a few more experiments trails for soybean crop.
