Abstract: An experiment was carried out in the Demonstration Farm of the Faculty of Agriculture, University of Khartoum, at Shambat, during the winter seasons of 1992/93 and 1993/94. The objective was to study the effects of irrigation water regimes on growth, yield and quality of the potato crop. Watering regimes used in the experiment were 500,600,700 and 800 mm per growing period in 1992/93 season and 240, 320, 400, 480, 560 and 640 mm per growing period in 1993/94 season. The Parshall Flume measuring device was used for the application of the required water regimes. The results showed that stem emergence was delayed by low water regimes. Vegetative growth and yield components responded positively to the increasing water regime up to 600 and 560 mm in 1992/93 and 1993/94, respectively. Highest (800 mm) and lowest (240 mm) watering regimes were associated with the lowest total and marketable yields. The highest yield of 17.9 tons/ha. was obtained by the watering regime 600 mm per season. Less water regimes (240­-500mm) were associated with low yield and high tuber infestation as a result of soil cracking and exposure of tubers to pests primarily potato tuber moth. It is concluded that the optimum irrigation water regime for the potato crop under Shambat environment ranges from 560 to 600 mm per season applied in 8 to 10 irrigations, depending on the prevailing climatic conditions.
