“…In this manner, Amin et al (2013) and Mahmoud et al (2014) revealed that, increasing nitrogen fertilizer level up to 100 kg N/fad., significantly increased root and sugar yields/ fad., also produced the highest sugar beet growth traits, but decreased sucrose percentage. In addition, many researchers reported that increasing nitrogen fertilizer levels up to 150 kg N/fad., gave a significant increase in sugar beet yield and its components (Abou-Shady et al, 2011; Osman, 2011; Abdou, 2013; Awad et al, 2013;El-Sayed, 2013), on the opposite, increasing nitrogen fertilizer level decreased significantly quality traits i.e. sucrose and purity (%).…”

Two field experiments were carried out at the experimental farm (Ghazala Village), Faculty of Agriculture, Zagazig University, Sharkia Governorate, during 2016/2017 and 2017/2018 seasons to study the influence of three planting densities, (28000, 35000 and 46666 plants/fad.) three levels of N fertilizer (80,100 and 120 kg/fad.) and two levels of potassium fertilizer (24 and 48 kg k 2 O/fad.) on yield and its attributes as well as quality of sugar beet grown in clay soil. Results of combined analysis illustrated that, decreasing planting density from 46666 to 35000 or 28000 plants/ fad., significantly increased root length, root diameter and fresh root weight g/plant; on the other hand the highest planting density (46666 plants/fad.) produced higher sucrose, extractable sugar percentages, sugar and recoverable sugar yields/fad., than low or medium densities. Raising N fertilizer levels significantly affected yield and its attributes as well as quality of sugar beet. Where, the results of the combined analysis indicated that, each increment of nitrogen fertilizer level from 80 up to 120 kg N/fad., cm was accompanied with a significant increase in root length, root diameter, fresh root weight/plant, root and recoverable sugar yields/fad., but significantly decreased sucrose (%). Data of combined analysis also revealed that application of 48 kg K 2 O/fad., significantly increased root yield attributes i.e., root length root diameter (cm), fresh root weight g/plant, sucrose, extractable sugar percentages, as well as, root and recoverable sugar yields ton/fad., compared with supply of 24 kg K 2 O/fad. Interactions between the studied factors (according to the combined analysis) indicated that the highest root yield (ton/fad.) was achieved when sugar beet was sown with the highest plant density of 46666 plants/fad., and fertilized with 120 kg N/fad. As well as, the highest value of root diameter (cm) was achieved under the application of 120 kg N/fad., and addition of 48 kg K 2 O/fad., while, the interaction between planting densities and potassium fertilizer levels had no significant effects on all studied traits.

Two split trials with four replications were conducted at the Bangar El-Sukar region, Burg El-Arab, Alex. Governorate, Egypt during 2018/19 and 2019/20 seasons to study the effect of two nitrogen sources fertilizers (ammonium sulphate 20.6% and urea 46%) with three rates (80, 100 and 120 Kg N/ fed.) on growth, yield components and quality characters and nitrogen use efficiency of sugarbeet grow on a clay loam soil. Results showed that significant differences were reported between sources of nitrogen fertilizer in the most plant growth characters, yield components, quality parameters and impurity parameters as well as nitrogen use efficiency (NUE) in the two seasons. Beet plants fertilized with ammonium sulphate as compared with urea significantly exceeded root and top fresh weight, root length, root diameter, leaf area index and total dry matter accumulation per plant as growth parameters, roots, top, gross sugar and white sugar as yield components, percentage of gross sugar, white sugar, quality index as quality parameters and NUE for yields of roots, gross sugar, white sugar and loss sugar in both seasons, and chlorophyll "a" in first season only. On contrary, also, ammonium sulphate significantly decreased concentrations of K, Na, α-amino-N as impurities and loss sugar% as compared with urea in both seasons. Application of different rates of nitrogen fertilizer in the two seasons, significantly affected all tested traits, except loss sugar yield and quality index in the first season only. Application of 120 Kg N/fed. rate recorded the highest values of all tested plant characters, photosynthetic contents, yield components, quality parameters and NUE for gross sugar and white sugar yields. . In addition, the same nitrogen rate produced the lowest values for all impurity parameters measured (K, Na, α-amino-N and AC), loss sugar percent, NUE for roots and loss sugar yields in the both seasons. The interaction between sources and rates of nitrogen fertilizer were significant effect on root length and fresh weight/ plant in first season only, root diameter, chlorophyll "b", gross sugar yield/ fed. , all quality parameters and NUE for loss sugar yield in the second season only. However, in the two seasons, roots, top and white sugar yields/ fed. and all impurities as well as NUE for roots, gross sugar and white sugar yields were significantly affected by the interaction between sources and rates of nitrogen fertilizer. In general, application ammonium sulphate fertilizer at the rate of 120 Kg N/ fed. was recommended because it recorded the highest root characterse, chlorophyll "b", most yield components and quality traits as well as NUE for gross sugar and white sugar yields, and the lowest loss sugar yield, loss sugar%, NUE for roots yield and all impurities traits.

“…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.
