Abstract
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.
