Zero Tillage or Reduced Tillage: The Key to Intensification of the Crop?Livestock System in Ethiopia
Numerous methods are available for increasing crop and livestock production in the Ethiopian highlands. Both national and international research institutes have developed technologies that are technically appropriate for these conditions. Examples of such technologies are the broad-bed maker for vertisols and cow traction (Zerbini, Woldu, and Shapiro 1999) and use of a single ox to pull the plow (Ouwerkerk 1990). However, farmers’ adoption of these technologies has been very limited, and farming is still characterized in most areas by low input use and limited use of improved technologies.
