Long term use of Maresha plow, a conventional plow pulled by oxen, has resulted in the formation of a restrictive layer thereby limiting water movement and aeration as well as root zone penetration in the soil profile. Several studies have shown that improved tillage practices can positively affe...

Different types of problems are to be tackled by West African breeders to make important improvement on the West African varieties. The most important are those that directly concern the morphology and physiology of the rice varieties. The first major change should be the reduction in height, and...

Irrigation has a large potential to increase agricultural output and yield per unit area. However, the long term sustainability increased production, together with degradation of the soils (and associated water bodies) in irrigated areas may be irreparably damaged by inappropriate watering schedu...

Draught animals have been used in Ethiopia since the third millennium B.C. It has been confined to land preparation and seed covering using the traditional implement 'maresha', pulled mainly by a pair of oxen under a ridged neck yoke. Even though research to replace the 'maresha' and to develop m...
