Over 80 percent of Kenya’s population derive, their livelihood from agriculture and related enterprises. Unfortunately only 15% of the land area receives 800 mm or more annual rainfall, and most of this land is already under intensive agriculture, (Figure 1). The remaining land area is classed as marginal in varying degree for unirrigated agriculture as a result or low and erratic rainfall. Nevertheless, it supports an estimated 4 million people out of a total of 14 million. At the current rate of growth, it is estimated that the resident population in marginal land! will increase :.e to over 10 million by the year 200o,plus substantial immigration from the high rainfall areas where land for tillage is now a major limiting factor. The task of feeding such a population will constitute a' major economic and social problem for the government unless viable farming systems for the dry lands can be developed. A major component of such a farming system is the development of a cropping system that maximises water use efficiency on the farm. This is the background of the research project reported in this paper
