Two field experiments were carried out at Sakha Agricultural Research
Station Farm during the two successive winter seasons of 2004 and 2005 using
sugar beet (Beta vulgares) to asses the effects of seedling methods. phosphorus
fertilizer management and sprayinq v, .tr. some nutrients on the yield. Split spilt plot
design was used With four replicates. The plot area was 27 m² Tne main plots were
assigned to two seedling methods 1- manual seedling, and 2- mechanical seedling.
The sub plots were assigned to two regimes for phosphorus fertilizer applicanon 1-
application of the recommended phosphorus fertilizer as one dose before the
seedling and 2- application of the phosphorus as two equal doses. the first before the
seedling and the second one month after sowing. The sub sub plots were asslgred
to four nutrient spraying 1- water as control. 2- rnaqnesium (300 mg L") as MgSO •.
3- boron. as boric acid and 4- boron + magnesium The obtained results can be summarized as follows: The manual seedling gave higher root yield than the mechanical seedling. but the
differences were not significant. The highest top yield was obtained with the mechanical seedling The increases
were statistically highly significant.       3     The highest sugar percent was recorded with the manual seedling method and
the increases were highly significant       4     Splitting the phosphorus fertilizer caused Insignificant Increase in the root yield
and significantly decrease in the top yield. Spraying with boron significantly increased Ihe rool yield in the first season and
highly significant in the second season. Meanwhile. spraying With MgSO.
reduced the root yield and increased top yields in both seasons Splitting the phosphorus fertilizer Significantly reduced Na% in the juice and
InSignificant reduce of K% in the juice.
