Abstract
 
These experiments were conducted at El- Kharga and El-Dakhla Oases  (latitude 25.45 and 25.48 oN respectively) at the governrate of New Valley during the fall/winter seasons of 1996/1997 and 1997/1998.  Two potato cultivars (Draga and Diamant) were planted and irrigated using the trickle irrigation system at two irrigation regimes (30 and 60 min daily = 840 and 1680 m3/ season). The sprinkler irrigation system was tested at 30 min daily level (1680 m3/ season) vs the drip irrigation regimes  at Dakhla location only. The strong winds resulted in an irregular distribution of the sprinkled water.  That lead to an even  potato plant growth and a low total and marketable yield. Some physical and chemical characteristics of the soils and water of the two locations were conducted. The combined analysis of variance over the two seasons indicated that the use of the trickle irrigation system at 60 min. resulted in improving the yield of the tow potato cultivars. Sowing Diamant cv. resulted in more yields, than Draga cv. at the two locations. However, the water use efficiency was higher in the 30-min irrigation regime and it is advisable to be used there to increase the cultivated land and total yield. Finally the Dakhla location was superior to the Kharga location which may be due to differences in soil fertility and water quality.
