| This study was carried out to verify the experimental data of sugar beet in Kafr El-Sheikh Governorate in connection with the climate change from point of view. In particular, sowing date, and other bed-water relations. Therefore, this investigation sets out to analyze the climatological change in Kafr El-Sheikh Governorate (middle north Nile Delta) for a period of 30 years (1972-2002) to find out the impact effect of climate change on several scenarios of sowing date, how much water to be applied. what the suitable interval between irrigations and prediction of yield reduction at different growth stages under different water supply. The sowing dates of sugar beet under study are: 1“ Oct, 1St Nov. and 1St Dec, respectively. The main findings can be summarized as: (D Rainfed agricultural resulted in yield reduction of 35.6 and 76.1% for 1-51 Oct, 31.7% and 33.7% for 1'”t Nov. and 65.7% and 96.6% for 1" Dec. at mid and late season, respectively. is. rainfall is not sufficient to produce sugar beet in the studied area. — CE) Under shortage water supply, of water regime net irrigation 160.0 mm for 151 Oct. and irrigation intervals of 40 days resulted in yield reduction of 10.8% at late season stage. While for 1‘t Nov. net irrigation of water regime 279.9 mm and interval of 40 days resulted in yield reduction of 5.6% at the same stage. Whereas, net irrigation for 1'“ Dec. 475.9 mm and irrigation interval is 30 days resulted in yield reduction of 9.1% for the same stage. (D Under adequate supply of water, i.e. no yield reduction i.e. at mid and late-season, for 1llit Oct. minimum net irrigation 245.0 mm and irrigation interval 21days. for ‘1st Nov. minimum net irrigation 375.0 mm and irrigation interval 20 days and for 15t Dec. minimum net irrigation 502.4 mm and irrigation interval 20 days are the adequate to get the maximum yield with no reduction on it as well as no water losses could be obtained. | ||||
