Experiments were conducted on field (2014) for knowing the effect
of nitrogenous fertilizers (Ammonium Nitrate, Urea, Ammonium
Sulfate) in increased concentrations with
two ways of fertilization (Scattered, local) in growth of the young
Beet plan
ts class Dita (dry weight, density rooty, content of soil and
plant from nitrogen) under condition of soil and climate in Deir
Ezoor.
The study included the reality of marketing crop sugar beet in Syria in general, and
in al ghabb 's area , in particular, has shown results that the problems and difficulties of
marketing sugar beet back to the non-compliance of farmers date of Agr
iculture
appropriate and space devoted to the cultivation of the crop sugar beet and assessed by the
General Authority to manage and develop Al Ghabb's area, in addition to the failure of the
extension units in turn supply the deadline cards provide timely and sufficient quantities to
farmers as a result of the process control system of favoritism in the distribution of cards
supply extension units.
In addition to the low energy manufacturing to the sugar mill, and its inability to
absorb the quantities produced in excess of the agricultural plan, along with breakdowns
lab frequent result gave the mechanisms used in it, and the need for frequent maintenance,
and low efficiency of some sections of the lab, and the control system favoritism determine
the degree of sweetness, as shown by the results Search also "high production and
marketing costs for sugar beet crop and is higher than its price.
Polymyxa betae is an important vector of many viral diseases and
widespread in Syria. It was necessary to determine the host rang of Syria's
isolate of the P. betae in the local plant species and their role as alternate host to
P. betae, as well a
s its role to transfer the P. betae to sugar beet cv. 186
dicotyledonous and monocotyledonous plant species were collected during the
years 2007 - 2010 from sugar beet fields with a focus on Rhizomania infected
fields regardless the planted crop. 10 dicotyledonous and two
monocotyledonous plant species were positively tested with naturally infection
of Polymyxa spp. In addition, 106 dicotyledonous and monocotyledonous plant
species kindly provided by the BASF AG (Germany) were tested in soil infected
with Syrian isolate of P. betae only. After microscopic examination only 23
dicotyledonous plants species belong to 10 families were positively tested with
P. betae. This study showed for the first time the infection of Cabbage, Brassica
oleracea and Radish, Raphanus sativus with P. betae. All Weeds were infected
with Syrian isolate of P. betae were able to transfer it to the roots of sugar beet.
Some of weed species which show in Literature that potentially-infected with P.
betae did not infect with Syrian isolate.
