This study was caried out at fields Hort. and Fores. Resea., Depart. of Agric.Resea.in Ninevah during ١٩٩٨ and ١٩٩٩ growing season to evaluate the performance of six cultivars of tomato for fresh marketing.

The study was carried out at AL-Rasheedia Agricultural Research Station,
Nineveh, to evaluate nine introduce pea cultivars for dry production, during
two fall growing seasons of (2000- 2001) and (2001- 2002).
The results showed that the cultivar,
P.S.510571 gave the highest value in
plant length at both two seasons. The cultivar, M.G.102703 was superior in the
number of pods per plant, pod weight, weight of 1000 seeds, and gave higher
yield of dry production per unit area (722.5 and 780.2 kg/ donum) for the two
seasons, respectively.
However, the width of pods wasn't significantly different among the
cultivars in both two seasons.
A field experiment was conducted at two environmentally different locations
(Damascus and Dara'a), to evaluate the performance of 16 barley genotypes
under rainfed conditions during the growing season of 2011-2012 in order to
study in the response
of some quantitative traits and determine the yield under
drought conditions. The experiment was laid out according to the factorial
complete randomized block design with three replicates for each genotype.
Significant genetic variation was found in the response of barley genotypes to
water stress. The performance of all genotypes was significantly superior in the
less dry region (Izra’a-Daraa) compared to the more dry one (Abo jarash-
Damascus) for all the examined parameters. Results revealed that the number
of grains per spike was significantly higher in most lines compared to Arabi
Abiad and Arabi Aswad, and the number of grains per spike was significantly
higher in the line29 (43.17 grain per spike). The number of grains per m2 was
significantly higher in line29,line64, Arabi Abiad and line14 (11177, 10809, 10802,
10744 grains per m2), respectively. The mean grain yield was significantly
higher in the line64, line14 and Arabi Abiad. (479.3, 476 and 443 gram per m-2),
respectively. Harvest index was significantly higher in all lines compared to
Arabi Abiad and Arabi Aswad.
This investigation was carried out in the fields and laboratories of Pome and
Grapevine Department, GCSAR/Syria, on some apple varieties i.e. Richared,
Mutsu and Tourly Winsap to determine the optimal harvest date and its effect on
storability. Fr
uits were harvested in (16/9, 26/9, 7/10, 17/10 and 30/10) depending
on physical and chemical maturity indicators, and stored with the study of changing
in quality indicators and weight lost monthly. The results showed that the studied
varieties differed in their storability according to harvest date, Richared fruits in
26/9 showed long storage for seven months with weight loss of 4.9%, fruit firmness
6.4 kg/cm2, and 18.7% TSS. While the storability was six months for Mutsu fruits
which harvested in 7/10 with weight loss of 4.4%, and fruit firmness 6.1 kg/cm2,
and finally, Tourly Winsap fruits which were stored for five months in 7 and 17/10
harvest dates with fruit firmness 5.1 kg/cm2. Moreover, the three varieties were able
to storage for three months when harvested in 30/10 with weight loss of 3.3%, 4.4%
and 4.5% in Tourly Winsap, Richared and Mutsu respectively, which considered
as consuming maturity for these varieties. These results indicated to the various
storage periods according to fruits harvest time, and the storability, which assists
in regulating offer and demand, and providing markets with fruits for long period,
however harvesting at optimal time reducing the total weight loss, in addition to
high quality indicators.
The research was conducted at Abo-Jarash farm, faculty of
agriculture, Damascus university during the two growing season
2011-2012 and 2012-2013 in order to evaluate genetic variability of
some lentils genotypes based on some physiological and
productivity traits associated with drought tolerance. The
experiment was laid out according to factorial randomized complete
block design with three replications.
A field experiment was conducted during the two consecutive growing seasons
(2010/2011 and 2011/2012) at Ezra’ Research Station/Deraa/Syria in order to evaluate the
role of some agricultural practices in improving the performance of four wheat vari
eties
(Acsad1105, Acsad1229, Acsad885 and Acsad901) under rainfed conditions. The experiment
was laid according to factorial randomized complete block-split design with three
replications. The mean average of early vigor, flag leaf area, peduncle length and leaf area
index was significantly higher during the first growing season for the wheat variety
(Acsad901) at the first planting date with a nitrogen amount of (150 kgN. Hectar1), and
when nitrogen fertilizers were added twice (1.6-2.5, 53.4cm2, 16.3cm, 1.20 respectively).
The mean average of the same studied aspects, however, was significantly lower during the
second growing season in the case of the variety Acsad855 with regards to the early vigor,
as well as in the case of the variety Acsad1129 in the case of the leaf area Flag at a late
planting date, and without nitrogen fertilizers (3.6 4.5, 3.3 cm, 0.18, 16.6 cm2
respectively). The mean average of the grain yield was significantly higher during the first
growing season for two wheat varieties (Acsad901, Acsad1229) at the first planting date,
nitrogen rate 200 kgN. Ha-1, and when nitrogen fertilizers were added twice (660.4, 631.1
g.m-2 respectively), while it was significantly lower during the second growing season for
the variety Acsad1105, at a late planting date, and without nitrogen fertilizers (127 g.m-2).
Optimizing some important cultural practices helps increasing wheat grain yield by
improving morpho-physiological traits related to yield particularly the size of source
photo synthise (Leaf Area Index, Flag leaf area). The response of astivum wheat variety
was better compared to durum wheat. This shows the importance of improving crop
mangment factors in order to reach the maximum potential yield.
