降雨波动、干旱和干旱是苏丹雨养农业发展的主要制约因素。近年来，高粱的产量和产量一直在急剧下降。这主要是由于缺乏适当的土壤和降雨管理做法。据设想，在苏丹的普遍条件下，可以通过采用简单的集水技术来改善这种情况，目的是提高和维持小块(约50公顷)高粱的产量。在此基础上，研究了不同就地集水技术对高粱作物土壤含水率、产量及产量构成因素的影响。试验处理为等高坎(CR)、平坎(TR)、垄沟(RF)和宽平圆盘(WLD)。结果表明，集水技术具有较好的保水效果，从而提高作物产量。
Rainfall fluctuations, dry spells and drought are the main constraints for rain fed agriculture development in Sudan. In recent years the yield and productivity of sorghum have been declining drastically. This is mainly attributed to the lack of appropriate soil and rainfall management practices. This situation is envisaged can be improved under the prevailing conditions of Sudan by adopting simple water harvesting techniques with the intention of raising and sustaining sorghum productivity of the small holdings (about 50 ha). Accordingly a study was conducted to investigate the effect of some in-situ water harvesting techniques on performance of sorghum crop with respect to soil moisture content, yield and yield components of sorghum crop. Treatments tested were contour ridge (CR), tied ridge (TR), ridge furrow (RF) and wide level disc (WLD). The results showed that water harvesting techniques resulted in better moisture retention and hence crop yield.
