ABSTRACT
Studies were conducted over a period of three years (2011 to 2013) at the Ogongo Campus of the University of Namibia (UNAM), to compare the differences between tractors and animaldrawn implements both using conventional and Namibia Specific Conservation Tillage (NSCT) technologies. Two conventional tillage (CV) treatments (i.e. tractor-drawn disc harrow (TDH) and animal-drawn mouldboard plough (AMP) were compared to two NSCT treatments (tractor-drawn ripper furrower (TRF) and animal-drawn ripper furrower (ARF). There were four specific objectives. The first objective is to compare the field performances of the two technologies each for the NSCT and CV on (i) depth of cut, (ii) width of cut, (iii) draught of the power source (iv) efficiency and (v) effective field capacity under Ogongo conditions. NSCT technologies (TRF and ARF) performed better than CV technologies (TDH and AMP) on depth of cut in all the three years. Though the NSCT technologies also resulted in higher draught forces than the CV technologies, however, the specific draught of NSCT technologies were better across the three seasons showing that they were more energy efficient than CV technologies. Tractor drawn tillage methods resulted in lower specific draught than animal-drawn tillage methods across the three years. ARF performed better than AMP in the last two years.
