Farmers in Asia like to grow cassava because the crop will tolerate long dry periods and poor soils, and will produce reasonable yields with little inputs. Most farmers realize, however, that cassava production on slopes can cause severe erosion, while production without fertilizer inputs may lead to a decline in soil productivity. Research has shown that cassava yields can be maintained for many years with adequate application of fertilizers, and that there are various ways to reduce erosion.

Coordinated formal efforts to generate technologies for enhancing agricultural development in Ethiopia was mainly rooted in formal research and development institutions up to very recently. A number of improved technologies have been generated wlth the efforts made so far and the superiority of some of the technologies over the traditional practices has already been proved, at least for the major commodities.
