对西非南萨赫勒和苏丹气候带58个地点的长期日降雨量数据进行的分析表明，降雨开始日期与生长季节长短之间存在着重要关系。降雨早发病，相对于计算的平均数据的发病为一个给定的位置，导致在一个较长的生长季节。生长季节长度的概率早，正常和延迟开始下雨已经计算了所有的位置。这一分析在作物规划和灾害规划方面具有重要的应用，并形成了易受干旱影响的西非“反应农业”或“对天气敏感的作物管理策略”等概念的第一步。
Analysis of long-term daily rainfall data for 58 locations in the Southern Sahelian and Sudanian climatic zones of West Africa showed that a significant relationship exists between the date of onset of rains and the length of the growing season. Early onset of rains, relative to the computed mean data of onset for a given location, resulted in a longer growing season. Probabilities of growing season lengths for early, normal and delayed onset of rains have been computed for all the locations. This analysis has important applications in crop planning as well as disaster planning and forms an initial step in concepts such as "Response Farming" or "Weather-responsive Crop Management Tactics" for drought-prone West Africa.
