Abstract
The variability of rainfall in space and time is such that, even in climates that are classified as humid, crop yield losses due to limited water availability can occur. In these circumstances the effect of a dry spell can often be minimized through the use of supplemental irrigation. However, in semi-arid regions not only is rainfall limited, but supplementary water resources are often absent, too, and irrigation of agricultural crops is possible only in restricted areas. Thus, agricultural production in these areas is based mainly on rainfed agriculture.
