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 residues, 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 study was carried out at the Agricultural Scientific Research center In Sweida -
GCSAR to study the effect of potassium sulfate and organic manure on some of soil
characteristic in addition to tree growth vigor and fruit traits of Starking del
icious apple
cultivar. The results revealed significant effect in reducing the (pH) of the soil in the three
treatments; potassium sulfate fertilization, organic manure fertilization and application of
potassium sulfate and organic manure together which were (6.608), (6.708) and (6.558),
respectively, in the comparison with the control (6.768). In addition, significant differences
were shown in the (EC) between the former treatments (0.1532 ds / m), (0.1692 ds / m) and
(0.0937 ds / m) compared to the control (0.2217 ds / m). Concerning growth vigor and fuit
traits, the results showed a significant increase in the average of shoot length in the
previous treatments (66.43, 77.33 and 71.37 cm, respectively), compared to the control
(59.37 cm), while showed a significant increase in leaf area in organic manure treatment
and potassium sulfate with organic manure together (35.54 and 37.21 cm 2, respectively),
compared to the control (30.54 cm 2). The results of analysis of variance in fruit firmness
showed higher significant variation of potassium treatment (8.477 kg / cm 2) than the
other treatments which, also revealed significant increase of total soluble solids
(16.82%,15.2% and15.37%,respectively) compared to the control (14.23%), and a
significant increase in total sugars and in percentage of treatable acidity. Consequently, the
result showed that the addition of soil fertilizers treatment contributed to improve some of
soil characters, tree growth vigor and some of the quantitative and qualitative traits of
apple fruits.
The study was conducted at the Horticulture Department, Faculty of
Agriculture, University of Damascus, during the season of 2002 and 2003, in
order to study the effect of dipping apple fruits for the tow apple sorts for 5
minutes with some chemic
al substances, α-Tocopherol (0.25%) and
Prohexadion-Calcium (1%).
The fruits were stored at AlMaze cold storage unit under the normal
storage condition (0-1ºC, 93% R.H.), to find out some effects of these
treatments on some physical, chemical, and physiological changes of treated
and untreated apple fruits, especially: fruit weight, firmness, starch, and
soluble solids content.
Analysis of variance indicated a significant difference in storage ability of
both fruit apple samples in case of dipped fruits in Procalcium solution 1%
compared with control fruits. The tocopherol treated fruits were sometimes
significant.
The results showed a reduction in fruit weight in case of treated sample
during cold storage time. Fruit firmness was significantly better in both
treatments of procalcium 1% and tocopherol 0.25%compared with control,
and reducing physiological disorders during cold storage period.
In this research, we have studied the effects of some summer pruning at the
mid June and Juli, in addition to the common periodical winter pruning during
February.
Both studies were done to evaluate calcium concentration of fruits, quality
and yi
eld the apearance of physiological disorders during the storage and
fruits. Experiments were conducted on 8 year apple trees of Starking Delicious
and Golden Delicious, which are sensiitve to laek of calcium and as a result
caused bitter-pit as an important physiological disorder on apple fruits.
Summer pruning of apple trees at mid june increases their content of
calcium and their colors, also decreases physiological disorder, weight loss
during storage, without affecting the annual yield of trees.
Accorrding to the attained results, we recommend the farmers of apple trees
to follow summer pruning, because of its benefits on improving the condition of
trees and achieving the balance between vegetative and generative growth, and
reduced the alternate Summer pruning. Also improve the quality of fruits, their
storability and their resistance for some physiological disorders during storage.
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%.
The study was performed in Barshin Research Station- General
Commission for Scientific Agriculture Research on the trees age of
13 in grafted with Golden Delicious Cultivar on three rootstocks
(seedless rootstock Malus domestica, vegetative strong
rootstock
MM109, and MM111 half strong rootstock) over the years
(2014.2015 ).The study focused on growth vigor (the stem
circumference above the grafted area ,crown size - the rate of
shoots length and productivity).
