The quantitative response of groundnut to a wide range of temperature, humidity, and soil-water deficits is discussed in relation to the climate of the s2048emi-arid tropics (SAT). Information obtained from controlled-environment facilities is used to provide a model applicable to the SAT. The consequence of irrigation and rainfall distribution on crop phenology and the general relation between phenology and yield are also discussed. The limited information on daylength responses suggests that genotypic variation is an important factor. Humidity or saturation deficit does not have a direct effect on crop phenology and would probably influence phenology via the water-depletion rate in the soil. Delays in the start of the rainy season reduce the length of the growing period which may result in lower yields. Agroclimatological factors which affect crop phenology may also have a major influence on growth processes, e.g., in partitioning of dry matter to pods by temperature. Therefore, studies of phenology and growth processes should be integrated in crop-weather investigations.
