| Abstract | ||
| Two field experiments were carried out at Belkas district, ElDakhlia 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 α- amino 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, LP12 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, P12 and Demapoly varieties were the proper varieties for El-Dakhlia Governorate | ||
