Two field experiments were carried out at Belkas district, El-Dakhlia Governorate during 2008/2009 and 2009/2010 seasons to evaluate quality and yields of five sugar beet varieties namely (LP11, LP12, LP13, Demapoly and Kawemira) under three harvesting dates (175, 190 and 205 days after sowing). Results can summarize as the following: 1. Delaying harvesting dates from 175 to 205 days after sowing led to significantly increases in root fresh weight, root and sugar yields/fed, as well as, significantly improved juice quality (sucrose%, Extraction sugar% and Extractability%). Moreover, impurities (K, Na and αamino N %) were significantly decreased with delaying harvest date at 205 days from sowing. 2. Results revealed the clear superiority of Kawemira variety in root fresh weight/plant, root and sugar yields/fed. waile, LP 12 and/or Demapoly varieties had the highest value for sucrose, extraction sugar and extractability percentages in one or both seasons. 3. Interaction between harvest dates x varieties had insignificant effect on all studied traits in both seasons. 4. Under the conditions of this study, Kawemira, P 12 and Demapoly varieties were the proper varieties for El-Dakhlia Governorate environment.

Background: Endometrium examination by Ultrasound is commonly used to assess the endometrial receptivity during in vitro fertilization (IVF) treatment. Aim of the work:To evaluate the role of pulsatility index (PI) of uterine artery blood flow during IVF-ET cycles in prediction of pregnancy rate.

Two field experiments were carried out Sakha Agricultural Research Station, Kafr El-Sheikh Governrate, during 2009/2010 and 2010/2011 seasons to evaluate three sugar beet varieties (Kawemira, Carolla and Farida) under two sowing dates (15 th October and 15 th November), and two harvesting dates (180 and 210 days from sowing date). Results can be summarize as the following: 1. Sowing sugar beet on 15 th Oct. attained the highest values of root length and diameter, root and top fresh weight/plant, sucrose %, Total Soluble Solids %, purity %, root and sugar yields t/fed. 2. Sugar beet vaieties were differed in the stydied characters: Carolla variety was superior in root and top fresh weight/plant, sucrose %, TSS %, purity %, root and sugar yields/fed. 3. Delaying harvest date up to 210 days from sowing gave the highest root dimension (length, diameter), root fresh weight/plant, root yield/fed and the best quality (sucrose %, TSS %) root and sugar yields/fed. 4. A significat interaction between sowing dates and harvesting dates gave the highest values of sucrose %, root and sugar yields/fed in both seasons, root diameter in the first season and total soluble solids in the second season only. 5. Results cleared that significantly interaction between harvesting dates and varieties in root fresh weight/plant Carolla variety gave the highest value of root fresh weight/plant at harvesting date 180 days from sowing. Generally, it could be recommended that sowing sugar beet variety Carolla on 15 th Oct. with delaying harvesting date up to 210 days from sowing under Kafr El-Sheikh conditions to obtain the higher sucrose % and root and sugar yields/fed.

Two field experiments were carried out in a sandy soil at El-Qureen, Sharkia Governorate Egypt during 2009/2010 and 2010/2011 seasons to study the response of some multigerm sugar beet varieties i.e., Top, Sultan and Kawemira to foliar spray at 60 and 75 days from sowing with three levels of compost tea (0.0, 1.5 and 2 L/fed/300 L water). The experimental treatments were allocated in a split plot manner with four replications.The obtained results showed that foliar spraying with compost tea at the level of 2.0 L/fed significantly increased root length, diameter, fresh weight/plant, sucrose%, purity%, root and sugar yields/fed in both seasons. While, it decreased root mineral contents (N, Na and K%) as compared with zero treatment (control) or 1.5 L/fed level of compost tea.Sugar beet varieties significantly differed for root length, diameter, fresh weight/plant, sucrose%, purity% and root and sugar yields/fed, root mineral contents. Kawemira variety surpassed the other two varieties Sultan and Top in most studied traits in both seasons.The interaction between foliar spraying with compost tea the at level of 2.0 L/fed and Kawemira variety recorded the highest values for sucrose%, root and sugar yields/fed in both seasons. Generally, it could be recommended that sown Kawemira, Sultan and Top varieties, respectively, sprayed with 2.0 L/fed compost tea to obtain the highest sucrose%, root and sugar yields/fed and yield quality in a sandy soil at El-Qureen, Sharkia Governorate.

The major goal was to study the response of five multigerm sugar beet varieties namely; Oscar poly, Desprez poly N, Pleno, Nejma and H poly to three nitrogen fertilizer levels, i.e., 100, 120 and 140 kg N/fed.The obtained results revealed that Desprez poly N variety significantly increased in growth traits, i.e., root diameter, root fresh weight and sugar yield/fed, while Nejma variety significantly surpassed in sucrose% and root yield/fed, and reduction in impurities% in both seasons.Application of 140 kg N/fed. maximized yield productivity, represanted by improved average root weight, root and sugar yields/fed. However, juice impurities were increased as nitrogen level was increased from 100 to 140 kg/fed. On the contrary, a gradual reduction in sucrose% has been detected with the increase in nitrogen level over 120 kg/fed.The interaction between Desprez poly N variety and nitrogen fertilization up to 140 kg N/fed. recorded the highest values in root and sugar yields/fed. Under the conditions of this study productivity of sugar beet varieties could be maximize by supply sufficient nitrogen fertilization levels from 120 to 140 kg N/fed. Key words: Sugar beet genotypes, Different nitrogen levels and In newly reclaimed soils INTRODUCTIONSugar beet ranks the second sugar crop after sugar cane crop over all the world where it provides about 40% of the world sugar production. All sugar beet genotypes cultivated in Egypt are imported from foreign countries, so, it is preferable to evaluate them under Egyptian conditions especially under newly reclaimed soil to select the best suited ones. The varital differences in gen make up expression may be throw some light on their relative importance and behavior through the growing season. Osman et al (2003) showed that sugar beet Kawemira cultivar was superior in sucrose%, root, top and sugar yields/fed compared to cultivars Top, Lola, and Pleno. Aly ( 2006), Azzazy et. al. (2007) and El-Sheikh et. al. ( 2009) found significant differences among sugar beet varieties varied significantly for root fresh weight/plant, root and sugar yields/fed, while root length and diameter as well as sucrose and purity% did not differ significantly. Sugar beet variety KWS-9422 gave the highest root and sugar yields/fed. Enan et. al. (2009) revealed that sugar beet varieties differed significantly in all studied traits in both seasons. Sugar yield in the 1 st season, Farida variety gave a significant increase for sugar yield, juice quality, sucrose and purity% while it recorded the lowest values of impurities (Na, K and N%). Abd El-Aal et. al. (2010) detected significant variation in yield productivity and root quality among the varieties. Kawemira and Gloria varieties gave the
