Studies on draft requirements of bullock drawn mouldboard ploughs in sandy loam soil of coastal Odisha
Author(s): MK Ghosal and N Mahapatra
Abstract: The draft requirements of four types of mouldboard ploughs namely CAET, Downsize, Implement factory and Heavy soil mouldboard ploughs in sandy loam soil at two depths (100 mm and 150 mm), two speeds (1.25 kmph and 2.0 kmph), soil moisture conditions (in the range 10-11 %, wet basis) and soil resistance (in the range of 800-1000 kPa) were studied in OUAT, Bhubaneswar during 2016. The Downsize mouldboard plough was evaluated only at 100 mm depth due to its small size. The results indicated that ploughing depth had more pronounced effect on the draft of the above ploughs than the forward speed. The Downsize OUAT MB plough was found suitable for a pair of bullocks of body weight of about 400-450kg i.e. for small size bullocks which can develop a draft of 400-450N. The other three test ploughs were found suitable for the bullock pair with total body weight of about 700kg i.e. for medium size bullocks developing a draft of 600-650 N.
