“…Differences among sugar beet varieties for LAI, top and root fresh and dry weight and total dry weight were also detected by Mohamed (2008). Ouda (2009) showed that root length and diameter of the variety Lados were significantly higher than Athose poly. Also, Al-Labbody (2003) found differences among sugar beet varieties in root length and diameter.…”

Two field experiments were carried out at the Agricultural Experiments Desert Station, Faculty of Agriculture, Cairo University in Wadi El-Natroon, El-Beheira Governorate, during 2008/2010 seasons, to study the response of three sugar beet varieties, i.e. KWF1436, Swello and Faraha to compost (CM) and Mineral-N fertilizer and their combinations, at five treatments : 4 tons fed -1 of (CM), 4 tons fed -1 of (CM) +80 kg N fed -1 (100% N), 4 tons fed -1 of (CM) +60 kg N fed -1 (75 % N), 4 tons fed -1 of (CM) + 40 kg N fed -1 (50 %N) and 80 kg N fed -1 (100 % N) on growth attributes of sugar beet under drip irrigation system. The obtained results revealed that the tested sugar beet varieties significantly differed in all the traits under study except for, top dry weight in the 1 st season and root diameter in the 2 nd one. KWS1436 variety was superior to the other two varieties in chlorophyll a and b in both seasons. The highest leaf area index (LAI), root length and diameter, top and root fresh and dry weight, total dry weight were obtained by Faraha variety in both seasons. Application of 80 kg N fed -1 (100 % N) significantly increased the content of chlorophyll, a and b in beet leaves and gave the highest LAI and top dry weight in both seasons and the highest root length in the 1 st season. Combination of CM + 80 kg N fed -1 , recorded the highest content of carotenoids in beet leaves, root fresh and dry weight and total plant dry weight in both seasons and root diameter in the 1 st season. Various interaction orders among the two factors affected significantly all traits except for top fresh weight in the 1 st season.

“…El-Hinnawy et al (2003) showed that the genotypes significantly differed in root and sugar yields. Also, Ouda (2009) evaluated two sugar beet varieties (Athos poly and Lodos) and reported that, Lodos variety surpassed Athos Poly in top, root and sugar yields.…”

“…Sugar beet variety KWS-9422 gave the highest root and sugar yields. Ouda (2009) tested two sugar beet varieties (Athos poly and Lados) and found that, Lodos variety surpassed Athos Poly in top, root and sugar yields. On the other hand, Omar (2007) indicated that sugar beet varieties had no significant effect on root and sugar yields in two seasons.…”

Two field experiments were carried out at the Agricultural Experiments Desert Station, Faculty of Agriculture, Cairo University in Wadi El-Natroon, El-Beheira Governorate, during 2008/2010 seasons, to study the response of three sugar beet varieties, i.e. KWS1436, Swello and Faraha growing in sandy soil to compost (CM) , Mineral-N fertilizer and their combinations, at five treatments : 4 tons fed -1 of (CM), 4 tons fed -1 of (CM) +80 kg N fed -1 (100% N), 4 tons fed -1 of (CM) +60 kg N fed -1 (75 % N), 4 tons fed -1 of (CM) + 40 kg N fed -1 (50 %N) and 80 kg N fed -1 (100 % N) on yield and quality of sugar beet under drip irrigation system. The obtained results revealed that sugar beet varieties differed significantly in all studied traits in both seasons except for, sugar yield, purity % and sugar losses to molasses (SLM) % in the 1 st season only. KWS1436 variety surpassed the other two varieties in sucrose %, extractable sugar % as well as sugar yield, also, it gave the highest root yield (28.81 ton fed -1 ) and purity in the 1 st season. Swello variety recorded the highest root yield (29.96 ton fed -1 ), in the 2 nd season. In combination treatments, increasing N levels from 40 to 80 kg N fed -1 significantly increased top, root and sugar yields and sucrose %, in the two seasons. Combination of CM + 80 kg N fed -1 (100 % N), produced the highest extractable sugar % (15.53 %) in the 1 st season and increased root yield by (11.42 and 3.16 % ), sugar yield by (13.62 and 5.22 %) in the 1 st and 2 nd seasons, respectively and sucrose % by (2.08 %) in the 1 st season, as compared with adding 80 kg N fed -1 (100% N) alone. Combination of CM + 60 kg N fed -1 increased sucrose % by (4.13 %) as compared with 80 kg N fed -1 alone in the 2 nd season. Compost alone gave the highest purity and Alkalinity coefficient (AC) % and the lowest impurities (K, Na and Alpha-amino N %) and SLM% in the 2 nd season. Various interaction orders among the two factors affected significantly all traits under study. According to this investigation, to gain high sugar yield of sugar beet, KWS1436 fertilized by 4 tons compost + N level of 80 kg N fed -1 (100% N) is recommended under saline sandy soil conditions of Wadi El-Natroon and similar areas..
