Abstract:

Tillage is the basic operation in agriculture and its energy represents a considerable portion of the energy utilized in crop production. The objective of this study was to reduce the energy requirement for soil preparation. Performance evaluation of different type of tillage tools were studied by using a tool carrier in vertisol condition. According to the objective, shallow sweep and reversible shovel were tested in the field. Each tool was attached to the tool carrier and hitch with the help of tractor. To achieve the proper depth of operation, 200 kg weight was kept in the centre, above the tool carrier. Tool carrier was also operated at fixed speed (2.12 km/h).  It was found that, for both the tillage tools unit draft is inversely proportional to the depth of operation. Minimum unit draft was observed for shallow sweep (25.45, N/cm2). Statistical analysis reveals that tool shape had significantly different responses to the unit draft. The performance index of sweep was higher, i.e. 55.77, 51.08, 57.56% than that of shovel. The sweep was superior over shovel, although shallow sweep gave satisfactory results.
