Abstract

This study was conducted at Dongola Research Station Farm (DRSF), Northern State during 2004-2005 and 2005-2006 seasons. Two irrigation methods (main plots); Furrow and Basin and three wheat varieties (subplots); Wadi Elneel, Condor and Elneelain were tested in split plot design with four replications. The objective was to determine the best irrigation method (IM) or water management method (WMM) and the best wheat variety/ varieties in terms of water-application efficiency (WAE), water productivity, harvest index (HI) and grain yield. The results showed that the best water management method was Furrow irrigation system in terms of most of the water management parameters studied. The analysis of variance showed a highly significant difference among varieties in terms of grain yield; However, Elneelain out-yielded the other two varieties, Condor and Wadi Elneel. It also showed relatively high values of water- application efficiency, water productivity and harvest index. The results revealed a non- significant difference between the irrigation systems in terms of the grain yield produced. In both seasons, the amount of irrigation water applied in the Basin system was comparatively higher than that in the Furrow system by 10 and 14% in the first and the second season respectively. Both irrigation methods showed high values of consumptive-water-use during the flowering and dough stages. Elneelain performed better in the upper terrace soils than the other two varieties.
