Conservation Tillage Systems and Water Productivity - by Melesse Temesgen Leye

By Melesse Temesgen Leye

Conservation tillage platforms were followed by means of farmers in lots of nations to resolve the matter of land degradation and declining water productiveness. Direct software of such tillage structures has no longer been attainable between resource-poor, smallholder farmers in semi-arid components of Ethiopia. difficulties comparable to the shortcoming of rainfall, the prices of herbicides and implements, and the certain cultivation wishes of the crop tef, which may no longer be planted in rows, have built locally-adapted conservation tillage structures. This e-book considers conventional tillage structures and the result of assessments performed on applicable conservation tillage implements and platforms for smallholder farmers in semi-arid areas of Ethiopia. the normal tillage enforce, the Maresha Plough, and the comparable tillage structures have been pointed out as being the most explanation for repeated and cross-ploughing, resulting in land degradation and decreased water productiveness. changed implements have been came upon to be appropriate for conservation tillage structures whereas being easy, gentle and cheap. sorts of tillage platforms built for maize and tef have been chanced on to minimize floor runoff, bring up availability of water to vegetation and bring up yields.

Example text

As a result soils planted to tef are more compact than those planted to maize at both Wulinchity and Melkawoba. Field 2 and 3 are two different fields where maize was grown the previous year. It is also evident from the results that soils at Wulinchity especially those planted to tef are harder than those at Melkawoba. This could be due to textural differences, as determined earlier, soils at Wulinchity being heavier than those at Melkawoba. 25 m in order to disrupt the plow pan created by the traditional Maresha cultivation system.

In 1968, the Chilalo Agricultural Development Unit (CADU) started research on several types of tillage implements while the Institute of Agricultural Research (IAR) began activities on improving the traditional implements in 1974. However, none of these efforts were successful in developing prototypes acceptable by Ethiopian farmers (Goe, 1987). The major reasons behind the reluctance of farmers to adopt the newly Research Background 17 introduced implements were the fact that they were too heavy and expensive (Goe, 1987).

However, the traditional oxen drawn implement, the Maresha plow, has been found to force farmers to undertake repeated and cross plowing, which causes land degradation (Chapter 3). Therefore, there is a need to come up with improved implements that can undertake conservation tillage systems without being too expensive, too heavy and too sophisticated for the resource poor smallholder farmers in semi-arid regions of Ethiopia. , 2001). These implements were developed as attachments to the mould board plow frames that are too heavy and unaffordable by smallholder farmers in Ethiopia (Goe, 1987; Temesgen, 2000).
