Farmer participatory tillage trials were conducted in a highland Vertisol area of Ethiopia during the 1999 and 2000 croppingseasons. This participatory initiative clearly demonstrated that incorporating farmers’ knowledge, ideas and preferences couldimprove the wheat production package. A traditional practice of Chefe Donsa farmers—applying ash from their homesteadsto their fields to enable early-sown crops to withstand frost—led to the verification of the yield-enhancing effect of inorganicpotassium fertilizer on wheat. Farmer adoption of a minimum tillage production system increased the gross margin of wheatproduction by US$ 132 per hectare—based on 1999 prices—relative to the traditional flat seedbed system. The minimumtillage system was characterized by a much lower level of soil manipulation relative to the traditional flat seedbed system,and, as a consequence, markedly reduced the total human labor and draft oxen requirements for wheat production. Thus, theminimum tillage system could be an effective intervention for soil conservation due to early-season vegetative cover of thesoil surface. Also, the early crop harvest associated with the minimum tillage system was highly beneficial for small-holderfarmers—since the early harvest coincided with the cyclical period of severe household food deficits and high grain prices inlocal markets.
