“…This effect was due to the pronounced effect of nitrogen fertilizer levels on root yield (Table 3). These results are in line with those reported by Abo-Shady et al (2011), Osman (2011, Sarhan et al (2012), Seadh (2012), Abdou (2013) and Abdou and Badawy (2014).…”

“…Khalil (2010) found that increasing nitrogen levels from 80 to 100 and 120 kg/fad significantly increased root length, root diameter, root fresh weight/plant, root yield and the percentages of Na, K and alpha-amino nitrogen and sugar loss to molasses. Abo-Shady et al (2011) found that increasing nitrogen fertilizer levels from 75 to 90 and 105 kg N/fad caused significant increase in root, sugar and top yields as well as Na, K and alpha-amino nitrogen in root contents and sugar loss in molasses in both seasons. On the contrary, they added that sucrose, purity, extractable sugar percentages and alkaline coefficient recorded low averages in both seasons.…”

Two field trials were conducted during 2012/2013 and 2013/2014 seasons at El-Manyal Village, Talkha District, Dakahlia Governorate, to study the effect of plant distribution sowing patterns and nitrogen fertilizer levels on yield and quality of sugar beet, "cv. Kawemira". The obtained results indicate that: 1-Sowing distribution patterns had significant effects on all studied characters over the two seasons, except for root diameter in the second season The studied sowing patterns (28, 24 and 20 or 35, 30 and 25 cm between hills in the two sides of terrace (mastaba) led to significant differences on the most of the studied characteristics in both seasons. Sowing beet seeds in both sides of terrace 80 cm width at 25 cm distance between hills led to significant increase in yields of roots, gross sugar and white sugar (t/fad) as well as the percentage of the extractable white sugar. 2-Increasing nitrogen fertilizer levels from 80 to 100 and 120 kg N/fad, significantly increased root fresh weight (g), root diameter, sugar loss percentage, the yields of root, gross sugar, white sugar and lost sugar/fad in both seasons besides root length (cm) in the second season. On the other side, it significantly decreased root gross sugar and extractable white sugar percentages in both seasons. Generally, it could be concluded that sowing sugar beet seeds at 25 cm apart between hills on the two sides of terrace (mastaba) 80 cm width and adding 120 kg N/fad is recommended to maximize its productivity and quality under the environmental conditions of Dakahlia Governorate.

“…In other words, increasing nitrogen fertilizer level significantly increased impurities parameters and decreased sucrose, purity and extractable sugar percentages which could be attributed to reasons that high levels of nitrogen fertilizer increased non-sugar substances such as protein, amino acids and other substances which lead to decreasing sucrose (%), purity (%) and extractable sugar (%) as explained by Gobarah et al (2010). These results are in accordance with those reported by Ramadan et al (2003), Geweifel et al (2006), Abou-Shady et al (2011), Osman (2011 and Omar and Mohamed (2013) who indicated that increasing N-levels had a significant negative effect on sugar beet quality. In addition, Mekdad (2015) stated that, increasing nitrogen fertilizer level up to 140 kg N/fad., significantly increased SLM, K, Na and alpha amino N percentages whereas nitrogen fertilizer level had no significant effect on purity (%).…”

“…In this respect, Geweifel et al (2006) revealed that, increasing nitrogen fertilizer level from 96 to 210 kg N/ha significantly increased sugar beet top, root and sugar yields and decreased sucrose percentage under sandy soil conditions in Egypt. Furthermore, many investigators reported that increasing nitrogen fertilizer levels up to 150 kg N/fad., resulted in significant increase in sugar beet yield and its components (Seadh, 2008;Abou-Shady et al, 2011;Osman, 2011;Abdou, 2013;Awad et al, 2013;El-Sayed, 2013), on http:/www.journals.zu.edu.eg/journalDisplay.aspx?Journalld=1&queryType=Master Zagazig J.

In order to investigate the effect of four nitrogen fertilizer rates i.e. 35, 70, 105 and 140 kg N/fad., and four compost rates i.e. 0, 2, 4 and 6 t/fad., and their interactions on yield and its attributes as well as quality of sugar beet (Beta valgaris L.) variety Top, grown in sandy soil under drip irrigation system. Two field experiments were conducted at the Agricultaral Researsh Station, Fac. Agric., Zagazig Univ., at El-Khattara Region, Sharkia Governorate, Egypt during the two successive winter seasons of 2011/2012 and 2012/2013. Regarding to the combined analysis of the both seasons, it could be noticed that increasing N fertilizer level from 35 to 140 kg N/fad., significantly increased root diameter, fresh top weight/plant, fresh root weight/plant, Na (%), K (%), alpha amino-N (%), top, root and recoverable sugar yields/fad. Root length and sugar loss in molasses percentage (SLM%) were responded only to 105 kg N/fad. The highest averages of sucrose and extractable sugar percentages were obtained by application of either 35 or 70 kg N/fad. Whereas, purity percentage significantly decreased with each increase in nitrogen fertilizer levels. Results clearly revealed that increasing compost rates up to 4 t/fad., significantly increased root length and diameter, fresh top weight/plant, fresh root weight/plant, Na (%) and SLM (%). The highest top, root and recoverable sugar yields as well as alpha amino-N (%) were achieved by application the highest rate of compost (6 t/fad.). The highest averages of sucrose, purity and extractable sugar percentages were obtained by the control treatment. In addition, the interaction between nitrogen fertilizer and compost rates significantly affected root length and diameter, fresh top weight/plant, fresh root weight/ plant, purity percentage, top, root and recoverable sugar yields/fad. It could be summarized that N-fertilizer level of 105 kg N/fad., with application of compost at 6 t/fad., could be applied for maximizing sugar production and minimizing soil pollution by reducing the application of N-fertilizer.

“…Adding100 kg N fed -1 recorded the highest value of sugar yield (4.18 ton/fed) and caused a decrease in pol% by 5.74 and 16.89%, and Na, K, and alpha amino-N% compared with the control (80 kg N fed -1 ). Also Aboshady et al, (2011) reported that the application of N-at the rate of 105 kg N/fad. gave the highest root, top and sugar yields as well as Na , K, alpha amino-N and sugar loss in molasses.…”

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..
