Abstract
Potential evaporation far exceeds mean annual rainfall in four years out of five over more than 90 percent of East African land area (Dagg et al. 1970). In most areas, the frequency and persistence of favorable water balances are determined by the rainfall within the bimodal pattern and the water holding capacity of the soil profile. Success in efficient exploitation of rainfall and soil water for reliable production of seasonal food crops, therefore, depends largely on choosing the date of planting to coincide with the onset of the rains and on breeding drought escaping varieties to fit the rainfall seasons in different areas (Dagg, 1965).
