通过连续两季（2003/04和2004/05）在苏丹Gedarif州北方地区机械化耕作区的变性土上进行的田间试验，研究了耕作方式对土壤水分和高粱产量的影响。试验的耕作方法有：凿耕（0.20 m）、犁板耕（0.20 m）、圆盘耙耕（0.09 m）、宽水平圆盘耕（0.07 m）和免耕。结果表明，不同耕作方式对土壤油分水分含量无显著影响。宽水平圆盘犁与其他耕作处理相比，两季产量稳定。免耕和凿耕均显著提高了第一季高粱产量，联合收割机d分析表明：结果表明，免耕法在高粱生产中是可行的。
A field experiment was carried out for two consecut ive seasons (2003/04 and 2004/05 ) in the vertisols of the mechanized rainfed agricu ltural sector in the Northern region of Gedarif state, Sud an, to assess the effects of tillage methods on soil moisture content and sorghu m grain yield. The tested tillage methods were; chisel plowing ( 0.20 m), moldboard plowing ( 0.20 m), disk harrowing ( 0.09 m), wide level disk plowing ( 0.07 m) and zero-tillage. The results revealed no significant difference in s oil moisture content among the different tillage methods. The wide level disk plowing resulted in a consistent yield throughout the two seasons compa red to other tillage treatments. Zero tillage and chisel plowing resulte d in a significantly higher sorghum grain yield in the first season and combine d analysis. It is concluded that, zero-tillage is promising and justi fiable for the production of rainfed sorghum.
