Conservation tillage structures were followed via farmers in lots of nations to unravel the matter of land degradation and declining water productiveness. Direct software of such tillage platforms has now not been attainable between resource-poor, smallholder farmers in semi-arid parts of Ethiopia. difficulties akin to the inability of rainfall, the prices of herbicides and implements, and the detailed cultivation wishes of the crop tef, that can no longer be planted in rows, have constructed locally-adapted conservation tillage structures. This booklet considers conventional tillage structures and the result of checks conducted on acceptable conservation tillage implements and platforms for smallholder farmers in semi-arid areas of Ethiopia. the conventional tillage enforce, the Maresha Plough, and the comparable tillage platforms have been pointed out as being the most explanation for repeated and cross-ploughing, resulting in land degradation and diminished water productiveness. converted implements have been came across to be appropriate for conservation tillage platforms whereas being easy, gentle and reasonable. different types of tillage platforms constructed for maize and tef have been discovered to lessen floor runoff, raise availability of water to plants and raise yields.
