Discusses inter-institutional collaboration undertaken in order to overcome the waterlogging constraint on vertisols of highland Ethiopia. Presents vertisol technology package for increasing crop and livestock productivity, and implemented by the joint project; good seedbed preparation, an animal...


Tedla, A.[Vertisol technology for smallholder farmers in Ethiopia]Vertisol technology for smallholder farmers in Ethiopia

Discusses the traditional and potential cropping systems for the highlands of Ethiopia. Traditional Vertisol management methods of these soils fail to overcome waterlogging problems, and therefore croping practices vary from place to place to suit the length of time left after the water is natura...


Tedla, A.Mohamed-Saleem, M.A.[Cropping systems for Vertisols of the Ethiopian highlands]Cropping systems for Vertisols of the Ethiopian highlands

This paper ilustrates the principle determining cropping systems for Vertisols by reviewing work in the highlands of Ethiopia. The types of cropping systems that can be applicable in the different Vertisol environments are briefly described. These cropping systems include single cropping; multipl...


Berhe, KahsayTedla, A.Mohamed-Saleem, M.A.[Cropping systems for Vertisols in the Ethiopian highlands]Cropping systems for Vertisols in the Ethiopian highlands

Since 1986 the Joint Vertisol Project (JVP) which involved a number of national and international research and Development institutions in Ethiopia gave high priority to developing alternative management practices for increased and sustainable food and feed production in highland vertisols. The J...


Tedla, A.Asamenew, G.[Food and feed production strategies for Vertisols in the Ethiopian highlands]Food and feed production strategies for Vertisols in the Ethiopian highlands

Presents and discusses the effects of animal power use for improved soil surface drainage on food and feed production on the vertisols of the Ethiopian highlands. Examines the on-farm technology validation programme at ILCA; describes crop/livestock interactions in these vertisol areas; highlight...


Asamenew, G.Jutzi, S.C.Tedla, A.McIntire, John M.Ikavalko, E.[Improved draught power use for increased food and feed production on Ethiopian highland vertisols]Improved draught power use for increased food and feed production on Ethiopian highland vertisols

Discusses intermediate technology for increased food and feed production from deep black clay soils (vertisols) in the Ethiopian highlands. Presents examples of improved soil/water/nutrient management on vertisols discussing tillage and animal powered surface drainage and its effect on crop yield...

Mamo, T.Tedla, A.Erkossa, Teklu[The effect of undersowing wheat with clovers on wheat grain yield, total crop residue yield and nutritive value of straw and fodder grown on Vertisols in Ethiopia]The effect of undersowing wheat with clovers on wheat grain yield, total crop residue yield and nutritive value of straw and fodder grown on Vertisols in Ethiopia
Sahile, G.Tedla, A.[The effect of weeding practices on grain yields of Durum wheat under two drainage conditions of a Vertisol in the Ethiopian highlands]The effect of weeding practices on grain yields of Durum wheat under two drainage conditions of a Vertisol in the Ethiopian highlands

Outlines an economic evaluation of an improved surface drainage technology, using the broad-bed-maker (BBM) on-farm in four different vertisol areas of the Ethiopian highlands. Presents data on crops and number of areas covered for the on-farm drainage technology, on cost structure of the BBM, an...
