ترجمة الملخص

The study was carried out in the Agricultural Scientific Researches Center in Hama , Ghab and Idleb on four cultivars of sugar beet : tow cultivars of Mono germ ( Sember & Atena )and tow cultivars of Multigerm ( HM10 & Mezano Ao poly ) . These cultivars were planted in the Autumn date on three times 1/10 & 15/10 & 1/11 . under the effect of five rates of nitrogen fertilization ( 0, 100 ,150 ,200,250 Kg N /hectar) in Agricultural Season2009-2010 and 2010-2011 in order to study the following :1-A study of the effect of the farming location in the percentage of Bolting in sugar beet .2-A study of the effect of the quantity of the nitrogen fertilization in the percentage of Bolting in sugar beet .3-A study of the effect of the timing of planting of the Autumm date in the percentage of Bolting in sugar beet .4-A study of the effect of the (Multi germ and Mono germ) in the percentage of Bolting in sugar beet .5-A study of the effect of the Phenomenon in the productive and technological specification of the sugar beet.6-A study of the effect of the differentiated experiments process in the productive and technological specification of sugar beet (non bolted) in the different locations of experiment.- showed an existence of the impact of the location and cultivar and the date planting and nitrogen fertilization on the percentage of Bolting where this percentage of bolting had increased in the early time of planting by1/10 and this percentage had arranged between the mean of the tow Seasons :12.25% in Hama location and 18.97 % in Ghab location , 25.07% in Idleb , however the percentage of Bolting had been decreased at the planting date 15/10 up to (12.12 , 3.46 ,5 %)in the location of Hama , Ghab and Idleb in consequence . In addition that this bolting Phenomenon at the late planting date 1/11.-Percentage of bolting was increased in cultivars when increasing the rate of added nitrogen fertilization in comparison with the moderate nitrogen fertilization where the percentage of the rate of the high nitrogen fertilization (250 kg N / ha) the average of the tow seasons 7.88% in Hama location and 10.28% in Ghab and 19.88% in Idleb location , where the percentage of bolting ranged between 4 –6.635 unfertilized process by nitrogen in the above three locations.-the cultivars were differentiated as of the resistance of bolting for Gentic factores and it was found that the tow cultivars (( Sember & Atena )( Mono germ)are more resistant to the bolting of the Multi germ cultivars ( HM10 & Mezano Ao poly ) . where the percentage of Bolting was ranged in both cultivars of Mono germ from 4.2 –9.25 % against 7.47 –15.54 % in the tow cultivars of the Mono germ in different above locations.-the productive and technological cultivars of the bolting sugar beet plants roots are deceased in comparison with the healthy plants , where the mene of the weight of the roots in the bolting plants was decreased in of 27.10% , 26.62 % and 36.97 % in the locations of Hama , Ghab and Idlab in consequence , and the percentage of decrease in the bolting roots weight in the mean of tow Mono germ cultivars amounted to 35.49% against 26.35 % in the tow cultivars of Multi germs studies in the mean of the tow seasons.-The sugar percentage was decreased in roots and sugar percentage in juice sucrose in the bolting roots , and the percentage of the sugar decrease in roots juice amounted in location to 24.75% and the juice locations, and the values of locations of Ghab amounted to 16.35 % and 85.095 for the tow above indicators on consequence.-As well as , Hama location was significantly superior over Ghab and Idlab by the productive percentage of the roots and actual sugar quantity and the values amounted to 92.40 ton /ha and 11.98ton /ha on consequence.-The Mono germ cultivars during the mean of the tow seasons wear superior on the multi germ in ranged of purity and the actual quantity of juice and the values amounted to 85.22 ton/ha , 16.75% , 11.24 ton /ha on consequence.-The date 1/11 was superior significantly on the tow dates 1/10 and 15/10 in regard of the productive percentage of roots (91.15 ton /ha) and the actual sugar quantity (11.93 ton /ha).-The high nitrogen fertilization process was superior (250 kg/ha) significantly on the other process of the nitrogen fertilization used in the productivity of roots (95.08 ton /ha) and the actual quantity of sugar (11.23 ton/ha) .The study concluded to that there is bolting phenomenon , taking in consideration not to exaggerate in the nitrogen fertilization over 200 kg/ha more preferable to concentrate of the planting of Mono germ cultivars , being superior under all the studies indicators over the Multi germs.
