    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 followed by one-time detailed formal farm surveys at Dogollo, Inewari and Ginchi in 1988/89. This chapter mostly presents the results of these formal surveys.

    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 depth-to-root-restricting layer). Distribution of Vertisols along the 12 physiographic regions of Ethiopia is described, the major agro-ecological zones of Ethiopia is listed, and distribution of Vertisols and their associations in Ethiopia is shown.

    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 existing levels of farmers' resources.

    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 vertisols and locations of study sites; a survey of the farming systems of Vertisol areas of the Ethiopian highlands, and modifying the management of vertisols. The report ends with a discussion on retrospect and prospects of the Joint Project on Vertisols management.

    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, broadbeds and furrows, field depressions, perched watertable, open ditches, height of beds, soil erosion and supplemental irrigation. The need for water shed development projects is also examined.

    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 potential remains underutilised because of the difficulty of managing these soils. This paper summarises available information on chemical properties, N, P and mineralogy.

    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/kg dry matter and 10.5 MJ metabolisable energy/kg dry matter. Half the ewes in each group interacted with harnessed vasectomized rams to detect oestrous, which was also verfied by weekly plasma progesterone assays. Ram presence did not depress feed intake or liveweight gain.

    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 second chapter is an introduction to the Borana plateau: natural resources and pastoral society. The next three chapters deals with vegetation dynamics and resoruce use, Borana household economy, and livestock husbandry and production.
