The present study was conducted on aerial offshoots of date palm
Berhi cultivar after separation from their mother trees, their bases were
dipped in solution of plant growth regulator (IBA).
The research was carried out at Jeb Ramlah Research Station – AlGhab Research Center -
General Authority of Scientific Agricultural Research at 2017 growing season. The
objective was to investigate the effect of three organic and bio fertilizers (B
acillus, Humic
acid and Amino acids) and three fertilization methods (Soaking seeds, Vegetative spraying
and Plant irrigation) in some morphological and production traits of cotton cultivar 124
(Gossypium herutum L.) The experiment was conducted according to RCBD with three
replications. The first factor (fertilizer type) occupied the main plots, while the second
factor (fertilization method) occupied the split plots. Statistical analysis was carried out
using the Genestat.12 software and the least significant difference L.S.D. at 5% level was
calculated. Studied traits included (at the beginning of Blooming stage): Plant Height,
Plant wet weight, Plant dry weight, Leaf area and plant production of cotton. The results
showed that the average of treatment of amino acids was superiority significant on the
others in terms of plant height (70.70cm), Plant wet and dry weight (201.50, and 83.41g),
respectively, Leaf area (4240.15cm2/plant) and plant production of cotton (75.13g). For
fertilization method, Vegetative spraying average was superiority significant on the others
in terms of all studied traits.
The research was carried out during the growing seasons of 2011 and 2012 to study
the effect of land leveling by laser, three tillage depths(01, 25 and 35cm) and three
irrigation systems with 7, 8, and 9 day intervals, along with the interactive ef
fect between
them on the yield of cotton (C.V Aleppo-90), irrigation management and net grossing. The
study showed the following results:
1- Land leveling by laser significantly increased the seed cotton yield, saved
irrigation water, and made net grossing higher as compared to no-leveling by laser through
the two seasons.
2- The two depths of tillage (25 and 35cm) significantly increased the seed
cotton yield, increased the irrigation water amount, and made net grossing higher as
compared to the depth of tillage (10cm)..
3- Increasing the irrigation water amount significantly increased the seed
cotton yield which reached 1441KG/H, and achieved higher grossing which reached 31360
S.P/H as compared to the lower irrigation water amount.
4- The interactive effect between the factors of this experiment gave a
significant positive difference. The best results were at (deep tillage 35cm × intervals 7
days × leveling by laser) through two seasons.
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 effect of different harvesting dates on the quality and storage ability
was studied for fruit of Coscia pear cultivar, which planted in the area of Daher
Aljabal- Sweida during two successive seasons 2007-2008. Fruit were harvested
in three di
fferent dates by week time intervals and stored for seven months at
(0-1 Cº and 90-95 % RH) in the storage units of apples and vine research
department. The effect of harvesting dates of fruit on the physical and chemical
properties was determined during period of 7 months in cold storage, by month
time intervals. The second date of harvest affected by decreasing weight loss
percentage, decay percentage, titratable acidity T. A, starch content and
firmness, in addition to that total soluble Solids T. S. S, number of acidity PH,
storage ability and shelf life were increased compared to the harvested fruit in
the different dates.
