A comparison of conventional and conservation tillage implements used for crop production in Omusati region of Northern Namibia

Experiments were conducted to test and compare the performance of four tillage implements (two for Conventional Tillage (CV) and two for Conservation tillage (CT) used by farmers in Omusati conditions of Namibia. The two CV implements are the animal drawn plough and the tractor drawn disc harrow whilst the two CT implements are the animal drawn and the tractor drawn ripper furrowers. The parameters evaluated were draught force, draught power, effective field capacity, field efficiency, average depth and width of cut during the various operations. The research design was a randomised complete block design. Results showed that there are significant differences (p = <0.001) in mean depth, draught and effective field capacity among the tillage methods. They show that draught requirements vary with implement type, speed of operation and depth of operation
