Abstract
Two field experiments were carried out in Tamiya AgriculturalResearch Station at Fayoum Governorate for the two successive growingseasons of 2008/ 2009 and 2009/2010 to study yield and quality of sugarbeet as affected by sowing dates included two sowing dates i.e. 15th July and15th November and some macro and micro nutrients treatmentsEach sowing date included 24 - treatment which were the combinationbetween three concentrations of foliar application micro nutrition (Fe, Mn,Zn and B) (0.5, 1.0 and 1.5 cm3 /L), two phosphorus rates (22.5 and 30 kgP2O5 /fed), two nitrogen rates (80 and 100 kg. N /fed) and two N- applicationmethod.Treatments were arranged in a split plot design with four replications.Foliar nutrient treatments were allocated in the main plots, whereas, thecombination between phosphorus rates, nitrogen application method andrates were distributed in the sub plot area. The results showed that:Sucrose in both seasons and purity percentages in the 2nd season weresignificantly increased when sugar beet was sown on 15th July, meanwhile,non of the examined concentration of foliage compound as well asphosphorus level and nitrogen application method attained any significanteffect on these characters. However, increasing the applied nitrogen let tosignificant decrease in sucrose % in both seasons of the 2nd sowing date (15thNovember). Moreover, purity % was not affected by nitrogen level in the 1stseason and in the 1st sowing date in the 2nd season. Meanwhile in the 2ndsowing date of the 2nd season, purity %was reduced significantly byincreasing in nitrogen level up100 Kg. N /fed.Tops yield was not affected by sowing dates, however root and sugaryields were significantly affected by sowing dates. Root and sugar yieldsignificantly increased in the 1st sowing date. Also foliage compoundtreatments affected root and top yields in both seasons. On the other hand,sugar yield insignificantly affected by foliage compound treatments.Increasing phosphorus application significantly increased tops and rootyield in both seasons, whereas sugar yield significantly increased with theincrease in phosphorus level in the 1st sowing date of the 2nd season. Drillingmethod of nitrogen application significantly increased tops yield in bothseasons, however increased root yield significantly in the 2nd sowing date ofthe two seasons. Also sugar yield was significantly increased by drillingnitrogen in the 1st season only.Increasing nitrogen rates let to significant increase in tops and rootsyield in both seasons, meanwhile, this increase was statistically for sugar yield in the 1st sowing date of the 1st season and in the 2nd sowing date of the2nd season.Based upon the obtained results and under this conditions, it could berecommended by the 1st sowing date and using nutrients compound (Fe, Mn,Zn and B) by 1.5 cm3 /L, 30 KgP2 O5 and 100 Kg.N/fed. by drilling method.
