“…Under the environmental conditions of Egypt, there is a general agreement that early planting of sugar beet during September-October results in the highest sucrose % as well as root and sugar yields per unit area (Lielah et al 2005, Nasr and Abd El-Razek 2008and Safina et al (2012 obtained higher root and sugar yields from sugar beet sown on October 10 th compared to that planted on November 10 th . Other studies found that planting sugar beet through October markedly increased weight of roots, sugar content as well as root and sugar yields, compared with beets sown in November Ghareeb et al 2013, Mahdi et al 2013, Ntwanai and Tuwana (2013, El-Mansuob and Mohamed (2014) and Hossain et al (2015) mentioned that sowing sugar beet on 15 th October significantly increased sucrose, Na, K, alpha amino-N, sugar lost to molasses and extractability %, purity% as well as top and root yields. Aly and Khalil (2017) found that sugar beet planted on October 1 st had higher values of root fresh weigh/plant, root and sugar yields/fed as well as the percentages of sucrose, corrected sugar, quality index and lower significant impurities compared with that sown on November 1 st .…”

In order to investigate the effect of nitrogen fertilizer levels, sowing date and harvesting age on growth yield and root quality of sugar beet. Four field experiments were conducted at Mallawi Research Station, El-Minia Governorate during 2015/2016 and 2016/2017 seasons. Sugar beet sown at two dates (the 1 st of September and October) fertilized with three nitrogen levels (80, 100 and 120 kg N/fed.) and harvested at three ages (180, 195 and 210 days after sowing). The results showed that all studied traits of sugar beet were significantly affected by sowing date in both seasons. The highest values of root length, diameter, root fresh weight, as well as α-amino N, Na, K, sugar lost to molasses, root and corrected sugar yields were obtained by delaying sowing date from September 1 st to October 1 st . On the contrary, an higher sucrose, quality and corrected sugar percentages were detected in beets sown earlier in September. Raising nitrogen fertilization level from 80 to 100 and 120 kg N/fed. resulted in a gradual and significant increases in root fresh weight, root length and diameter, root yield, sugar lost to molasses and corrected sugar yield in both seasons. While, alkalinity coefficient and quality percentages were decreased. The highest sucrose and corrected sugar percentages were recorded by applying 100 kg N/fed. The studied traits were markedly influenced by plant age at harvesting in both seasons. Root length and diameter, root fresh weight and yield/fed, sucrose, quality, corrected sugar percentages and corrected sugar yield/fed. were increased gradually with increasing plant age at harvest from 180, 195 to 210 days, in both seasons, while Na, sugar lost to molasses and alkalinity coefficient were decreased. Under these conditions of the present work, sowing sugar beet on October 1 st , with nitrogen fertilization at rate of 120 kg N/fed. and harvested at 210 days from sowing could be recommended to obtain the highest root yield/fed., while harvesting it after 195 or 210 days to get the highest sugar yield/fed.

“…Highly significant differences among the genotypes were detected for all studied traits except for fresh weight of foliage. The differences between genotypes may be due to their genetic makeup (El-Sheikh, 2007;Ghareeb et al, 2013).…”

This study was conducted to evaluate six fodder beet genotypes for their resistance to infestation under naturally infected root-knot nematode, Meloidogyne incognita during the 2015/2016 and 2016/2017 seasons in Nubaria region, El-Behera Governorate, Egypt. Highly significant differences among the genotypes were detected for all studied traits except for fresh foliage weight. The relative susceptibility to root-knot nematode parameters (gall index, gall size, gall area and damage index) indicated that two fodder beet genotypes Beta Rozsa and Jamon were considered as the best with high yield and resistant reaction to M. incognita; in contrast Starmon genotype had highly susceptible reaction while Jary, Mnro andVorosch genotypes had moderately resistant. Fodder root yield was positively and significantly correlated with root weight; meanwhile, it was negatively and significantly correlated with damage index and gall index, respectively. These findings indicate that selection for root weight and infestation involved in this study affected the variability of root yield. Stepwise multiple regression linear analysis for fodder beet yield showed that root weight per plant, gall index, number of leaves per plant and dry weight per plant were the most important contributing traits to root yield (R 2 = 94.76%). Hence, the selection among these traits would be accompanied by high yielding and more effective for the improvement of fodder root yield in the same conditions.

Farmers usually rely on various fertilizers to enhance the yield and productivity of crop species. However, these fertilizers are likely to affect performances and qualities traits of crops. To bring out the interaction between agricultural inputs and carrots characteristics, we studied their effect on yield attributes and chemical composition in three varieties of Daucus carota L.. Some yield parameters and chemical components of carrot roots were determined. Carrot's sweetness was also measured using a hedonic test. Fertilizers had a signifi cant effect (p<0.05) on both yield attributes and chemical components except moisture content. The results show that chemical components were signifi cantly different between carrot varieties. Interactions between fertilizer treatment and variety were signifi cant for most yield and chemical characteristics. Yield, carbohydrates and carotenoids were signifi cantly higher when using chicken manure as fertilizer. Compost fertilizer enhances important reducing sugars. Treatment using NPK fertilizer induced more proteins and iron. Calcium level was high when using either compost or chicken manure as fertilizer. Better Sweetness was obtained when using chicken manure. Chicken manure or compost; used alone or associated with NPK fertilizer increased agronomic and nutritional characteristics and in carrots.
