Using a linear programming model based on data from smallholdings in the Ethiopian highlands, this paper evaluates the farm level economic efficiency of cow traction and the traditional oxen-pair. Cow traction farm technology has the potential for increasing the net income of farmers at the…
Some of the papers in this report deals with nutrient management; land, soil and water management; grain, fodder and residue management; and technology validation and transfer. The other papers looks into development of coordinated research efforts; distribution and importance of Ethiopian…
This chapter reviews relevant Vertisol properties, experimental results and the overall experience of the project on this subject. There are several types of drainage problems in Vertisols whose magnitude may vary from site to site. Drainage improvement is discussed in relation with camber beds…
In 1986, ILCA carried out informal surveys at Dogollo and Inewari in order to understand the farming systems. Such surveys were also conducted by the Institute of Agricultural Research (IAR) at Ginchi in 1986 and by the Alemaya University of Agriculture at Ada/Debre Zeit in 1988/89. This was…
This chapter describes the distribution, use and importance of Vertisols in Ethiopia and indicates the study sites of the Joint Vertisol Project. Land and soil features are examined with particular reference to parent materials and landscape features, soil characterisation (colour, texture and…
Vertisols and soils with vertic properties are an important soil group in the Ethiopian highlands. Poor drainage, soil, water and nutrient erosion are the most serious problems on highland Vertisols. Due to their high moisture- storage capacity, they have high production potential and this…
Fourty eight mature Ethiopian Menz ewes were used to investigate the effect on nutrition on oestrous and ovarian activity in tropical sheeA control group was fed on hay alone and a high nutrition group received an additional 400g per ewe per d of a concentrate feed providing 263 g crude protein/…
The Borana plateau of southern Ethiopia: synthesis of pastoral research, development and change, 1980-91 summarises results from work conducted by 40 people in the southern Ethiopian rangelands between 1980 and 1991. The first chapter reviews rangelands and rangeland development in Ethiopia. The…
Studies were conducted among pastoralists on the Borana Plateau in 1986-89. Household surveys described seasonal milk production and allocation, marketed supply of dairy products, incidence of calf morbidity and mortality and human consumption of dairy products and grain. The efficiency of…
This study is part of a larger study on dairy marketing in Ethiopia, and concentrates on the producers'end of the marketing chain. Specifically, the markets of first sale used by dairy producers were identified and the marketing patterns of three categories of dairy producers (intra-urban,…
