An on-farm trial, in which a wheat-clover mixed cropping treatment was compared with un-fertilised (control) and N-fertilised (23 kg N ha (-1)) pure wheat treatments, was conducted at Ginchi (2200 metres above sea level (m asl)) and Deneba (2600 m asl) in the Ethiopian highlands. Compared with th...

The West African Semi-Arid Tropics (WASAT) is characterized by a monomodal rainfall pattern, and based on the amount of annual rainfall it can be divided into three ecologies: Sahel, Sudan and Northern Guinea savannahs. The major soil groups of the WASAT are Alfisols, Inceptisols and Entisols and...

Understanding the problems of grazing land in vertisol areas and seeking long-lasting solutions is the central point where mixed crop livestock is the second stay for the majority of the population. In order to understand this, the current study was conducted at two sites, one with 0-4% slope and...

The two years on-farm tillage research during the 1999 and 2000 cropping seasons in Ethiopian highland Vertisol area demonstrated the importance of adapting cultural practices into participatory trials. The minimum tillage package could be an effective intervention for soil conservation due to th...

Investigates the effects of improved surface drainage on the productivity of Vertisols in a wheat-and-chickpea cropping trial conducted in 1987 at ILCA;s Debre Zeit research site in the Ethiopian highlands. Chickpea plots were subjected to four irrigation treatments, viz, no irrigation, irrigatio...

Land degradation is one of the major problems related to low productivity in Ethiopia. Vertisols are potential agricultural lands but are underutilized due to waterlogging during the rainy season and are prone to soil erosion due to the traditional practices of planting crops at the end of the ra...
