The study was carried out in apple orchard and at the laboratories of Agricultural
Scientific Research Center, and Pome and Grapevine Division in Sweida (GCSAR),
Syria, during the growing seasons of 2015 and 2016 to study the effect of organic
res
idues, and boron and zinc addition on some soil characters, fruit set ratio and
some fruits qualitative traits in Starking delicious apple cultivar in Sweida.
This research was carried out during 2014 - 2015. The research aimd to describe
some chemical characteristics of the river's water used for irrigation, chemically compare it
with the Syrian Standards Specifications in terms of salt quantity and qua
lity and Cd and B
concentrations, water samples were taken from four observation points along the river:
A (domestic), B (industrial), C (mixed) and D (estuary), also Soil samples from the river
edges were also analyzed. The findings revealed that the EC value in B was 0.61 mg/l i.e.
less than those of others, with significant difference 0.72, 0.74, 0.73 mg/l, respectively.
The study also showed a significant increase in B and C concentration by 0.48 and 0.49
mg/l, respectively, compared with A and D by 0.4 mg/l each. A significant increase in Cd
concentration was noticed for B, C and D by 0.73, 0.88 and 0.75 mg/l vs. A 0.67 mg/l.
However, Cd concentration in the river water in all seasons and sites was excessive and
higher than the permissible limit for water discharge into seas estimated at 0.05 mg/l,
whereas the other parameters were lower than the permissible limits according to the
Syrian Standards. The effect of water pollution on soil showed a significant increase in EC
for B by 1.01 dS/m than others. The increase was also more significant in subsurface layer
than surface one by 0.45 and 0.62 dS/m, respectively. In addition, the findings
demonstrated a significant increase in Cd for C (2.67 mg/kg) than other points. The
increase in Cd concentration was more significant in the surface layer (2.648 mg/kg) than
the subsurface one (2.631 mg/kg), and this concentration was lower than the normal range
of soil content from Cd (3 ppm).
the experiment was conducted under Syrian coastal conditions to investigate (Vicia
fabaL.), the effect of boron and zinc foliar fertilization on faba bean,either individually or
in combination, by increased rates (0, 0.25, 0.50, 0.75, and 1 kg boro
n / has boric acid, and
zinc at a rate of 0, 0.375, 0.750, 1.125, and 1.5 kg / ha as zinc sulfate). where fababeans
were plantedin plastic pots(15L) in )2013/11/10(and )2014/11/10(.The soil in pots has high
content of calcium carbonate, low boron and zinc content, with pH slightly basic
(representative of the region's soils).
Half boron and zinc fertilizer rates were sprayed after 33 days of germination and the
other half ,after 65 days of germination. The results showed significant responses in all
studied parameters (number of branches,number of pods / plant, weight of 100 seeds, and
seed yield (Kg. / ha) on faba bean plant, as a result of foliar fertilization by boron and zinc.
Fababeans response to boron is higher than to zinc fertilization in all studied
indicators. However,the treatmentB75Zn75(0.75 kg boric acid and 1.125kg of zinc sulfate)
is the best, as compared to others. Also, the driedseeds yield was increased by about
17.66%.
This research carried out in Al- Bassa village at Lattakia province during 2013-2014, to determine the effects of increasing rates of boron and zinc fertilization by foliar spraying, on root nodulation and seed yield of broad beans (Viciafaba L.). Se
eds were planted in plastic pots (15 kg capacity), filled with sandy-silty soil, characterized by its poor content of boron, and represents most of lands in the region. Boron and zinc were sprayed by five increasing concentrations (Bo, B25, B50, B75 and B100) and (Zno, Zn25, Zn50, Zn75, Zn10)on broad bean plants at 33 and 65 days post-emergent. Results showed that treatments high significance than control, in termsof root length witch the best treatment was B100Zn100with 31c.m, and 2.85 g for B75Zn75 as a wight of length, on the other hand the best treatment for number of nodules was B75Zn75, 179.03 c.m, B100Zn100 was the best for height of the plant with 100.20, for protein B100Zn100 the best with 37.4%, However, boron and zinc fertilization treatment B75Zn75 is the best, economically.
Field experiment was conducted during the season (2011 – 2012) at Bhanine village
in Tartous city. Maize seeds of Ghouta 82 variety were planted in plastic pots filled with
calcareous soil .Treatments including three levels of B (0, 3, and 6 kg.ha−
1) and four levels
of Zn (0, 8, 16 and 24 kg.ha−1) added to the soil, in a completely randomized block design
with three replications, to study the effect of different levels of boron and zinc and their
interactions on maize content of some nutrients. Results of this study showed that there
was a clear effect of B and Zn and their interactions in soil on leaf content of Mn, Fe and
Cu. High amounts of zinc in the soil had a clear effect on reduced leaves content of B and
increased its content of K. The presence of a of B in the soil, assisted to increasing of leaf
N content. There was a significant effect of B and Zn interaction on leaf content of Zn, and
no effect on leaf P content.
Strawberry plants of Oso Grande variety has been treated with three types
of foliar fertilizers containing (Nitrogen, Boron, Manganese) individually and
combined, in addition to treating some of them using urea as soil fertilizer.
Some plants were untreated to be used as a control. Three concentrations were
used.
