| Abstract | ||||
| Two field studies were conducted in 2012/2013 and 2013/2014 growing seasons at Nubaria city Alexandria Governorate, Egypt during the two successive seasons, using sugar beet cultivar pleno to asses the effects of planting methods, phosphorus fertilizer management and spraying with some nutrients on sugar beet yield and quality. Split- split plot design was used with four replicates. The plot area was 27 m2. The main plots were assigned to two seedling methods 1- Manual planting, and 2- Mechanical planting. The sub plots were assigned to two times for phosphorus fertilizer application:- 1-Application of the recommended phosphorus fertilizer as one dose before the planting 2- Application of the phosphorus as two equal doses, the first before the planting and the second one month after sowing. The sub- sub plots were assigned to four nutrient spraying 1- Water as control, 2- Magnesium (400 mg L-1) as MgSO4, 3- Boron, (150 mg L-1) as boric acid and 4- Spraying with solution contain 150 mg L-1 boron + 400 mg L-1 magnesium. The obtained results can be summarized as follows:- Mechanical planting method, application of phosphorus fertilizer at two equal doses and spraying with B + Mg for sugar beet planting gave the highest values of root length, root fresh weight, root yield, sugar yield and sucrose % where as root diameter and top yield gave the highest values with manual planting and addition phosphorus fertilizer at one dose during land preparation, while addition some nutrients had no effected on top yields at two growing seasons. On the other hand migration coefficient not affected in both seasons by factors under study. Impurities values were affected significantly by manual planting and addition phosphorus as one dose in both seasons while, some nutrients not affected on impurities values in both seasons and recorded the highest values. Quality % and extractable sugar (ton/fed.) recorded the highest values in both seasons when sugar beet plants were sowed mechanically and phosphorus was added at two equal doses where as, addition B + Mg alone or mixture not affected on these traits in the first seasons only. | ||||
