COMPARATIVE ANALYSIS OF SECONDARY TILLAGE TOOLS IN VERTISOL
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 61
Abstract
Tillage is the basic operation in agriculture and its energy represents a considerable portion of the total energy utilized in crop production. Performance evaluation of different types of tillage tools was studied by using a tool carrier in vertisol condition. The tools include shallow sweep, right side sweep, left side sweep and heavy duty sweep. split plot design was used to study the performance evaluation of different types of tillage tools. Each tool was attached to the tool carrier and put in lower hitch position of the tractor. For maintain the proper depth of operation, 200 kg weight was kept in the center of the tool carrier. Tool carrier was also operated at fixed speed (2.12 km/h). It was found that, for all the tillage tools unit draft was inversely proportional to the depth of operation. Minimum unit draft was observed for heavy duty sweep i.e. 14.35 N/cm2 followed by shallow sweep, right side sweep, left side sweep (i.e. 15.43, 25.45, and 23.58 N/cm2). Statistical analysis reveals that tool shape had significantly effect on the unit draft. From the results, it can be concluded that heavy-duty sweep showed maximum performance index i.e. 70%. Also heavy duty was found superior over other tools, although shallow sweep gave satisfactory results in respect to field capacity and energy requirement.
