Abstract
Two field experiments were conducted during 2011/2012 and 2012/2013 seasons at Nubariya region, Behera governorate, Egypt (Latitude = 30°37'33.43"N, Longitude = 30° 2'2.49"E), under overhead sprinklers irrigation to find out the relative importance of nitrogen fertilizer on the quantitative and qualitative parameters of six sugar beet varieties and spread of Cercospora leaf spot . The experiment included 18 – treatment which were the combination between six sugar beet varieties viz. Cesira, Ferancesca Univers, Glorias, Panther and Kawemera and three nitrogen levels (60, 80 and 100 kg. N. /fed.) The results obtained showed that: Results given pointed out that increasing nitrogen level from 60 to 80 and 100 kg N. /fed. Significantly increased severity % of Cercospora beticola on sugar beet leaves. Concerning the influence of the examined varieties on severity % of Cercospora beticola, the collected observation clearly show that there was a significant difference between the tested varieties with respect to their effectiveness on severity % of Cercospora beticola. The highest degree of attack rate occurred in 33.44 % and 34.88 for variety panther in the 1st and 2nd season respectively and the lower degree of attack was 17.66 and 18.55 % for the variety Cesira in the same tested seasons respectively. The results pointed out that increasing nitrogen application was accompanied by increase in the values of Peroxidase, Polyphenoloxidaese and Catalease. Moreover,sugar beet variety cesira had a higher susceptibility to Cercospora beticola , where that the values of excreted amount of free phenols, Conjugated phenols and total phenol enzymes 68.429 ,141.156 and 209.584 corresponding 49.980 ,121.858 and 171.838 for sugar beet variety Francesca. It is also clear that adding 80 kg.N./fed. Was enough to attained relative and significant increase over the lowest one (60 kg.N/fed.) and /or the highest levels (100 kg.N/fed.) for top and root yields in the 1st and 2nd seasons. Also, sugar beet varieties Cesira, Francesca, Univers and Panther over passed Panther and Kawemera sugar beet varieties in respect to tops yield /fed. The studied growth criteria significantly differed by the studied varieties, In this respect sugar beet variety Cesira attained the highest root dimensions while sugar beet variety Univers recorded the highest root fresh weight/plant and variety Panther produced the highest leaves fresh weight/plant. Application of 80 kg N. /fed. Was enough to produce the highest values of root dimensions, leaves and root fresh weight/plant. Neither the examined varieties nor the studied levels of nitrogen affected the percentages of TSS, sucrose and purity%. The examined varieties differed with in this respect to N, K an alfa amino nitrogen %, however the lowest values of these measurements was recorded with the lowest value of nitrogen (60 kg N./fed).
