Draft Requirement of Bullock Drawn Mouldboard Ploughs in Sandy Loam Soil of Coastal Odisha

Experiments were conducted in the soil bin to measure 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 (10 and 15 cm) and two speeds (1.25 km/h and 2.0 km/h). The results indicated that ploughing depth had more pronounced effect on the draft of different ploughs than the forward speed. The down size OUAT MB plough was found suitable for a pair of bullocks of body weight of about 400–450 kg (small size bullocks) which can develop a draft of 400–450 N. The other three test ploughs were found suitable for the bullock pair with total body weight of about 700 kg (medium size bullocks) developing a draft of 600–650 N.
