This study considers the efficiency of irrigation water usage in the
economic and productive aspects of peanuts crop in Syrian lands, in
particular: mid, coastal and eastern lands, in terms of arithmetic
means during the period of 2010-2012.
A field experiment was conducted in Tartous Governorate, on
the Arachis hypogaea . L during tow growing season (2012-
2013)(2013-2014). Experiment was included 6 treatments with
three replicates: control (without fertilization), different rates of
Olive Mail Waste Water (OMWW) (5-10-15) l/m2 , organic
fertilizer (30 tn/h)and nitrogen fertilizer(30)kg/h.
The research aimed to know effect of these Additions on some
physiological groups of microorganisms, nodulation on plant
roots and nitrogen relative bacteria Arachis hypogaea . L. yield.
This research was conducted during 2014 season at Miaar Shaker
plains in Tartous region, to study the effect of applied drought stress for
24 days in 4 growth stages of peanut crop, i.e., 1. Brunching stage, 2.
Flower initialing stage, 3. Pod form
ation stage, 4. Seed formation stage,
beside of control (full irrigation by 12 days intervals). And effect of
these treatments on some growth attributes and yield to peanut
genotype (Sahel).
The experiment was conducted for one growing season 2011 at Teezen
Research Station in Hama Research Center-GCSAR in order to determine
water requirements, crop coefficient (Kc) and the effect of different irrigation
systems on productivity of pea
nut crop. Four methods of irrigation were used
(drip، sprinkler، mini sprinkler and surface irrigation) with three replications
for each . Experiment was designed on the basis of randomized complete block
with one water treatment (75% out of the field capacity). The results showed
superiority of drip irrigation in terms of water consumption, and total water
consumption (6522 m 3/h), which led to savings in irrigation water by (60.14%),
compared with traditional surface irrigation, with a consumption (13495 m 3/
h). It also outperformed drip irrigation when (p<0.05) in crop yield, reaching
productivity 5920 kg/ha, an increase of 22.57%, and total water use efficiency
1.91 kg/m3, compared with the (control) surface irrigation, reaching
productivity (4820) kg/ha. Followed by methods for: irrigation sprinkler sprays
small, with a water requirement (8999 and 9396 m 3/ h), and the efficient use of
water (0.67 and 0.58) kg/ m3, and the percentage of savings in water (36.65 and
31.98%), respectively, compared with surface irrigation traditional Phonology
developing did not show significant differences between irrigation methods in
terms of the dates of germination, flowering and maturity.
The experiment was carried out in Tartous Governorate in the Qubeiba region in the two agricultural seasons 2011 and 2012 to study the effect of different types of ploughs, the depth of plowing, and the timing of adding nitrogen fertilizer on some ph
ysical and chemical properties of the soil and some growth indicators of peanuts and its productivity. Three types of plows were used: MP ), disc plow ( DP ) and backhoe plow ( CP ) .
The study included the selection of the best methods to extract the enzyme
among nine methods. The protein content was concentrated and precipitated
by cold acetone among other five methods of concentration (partial
purification). The purification
stages were achieved by using ion exchange
column chromatography (DEAE – Sephadex A 50 column). Followed by gel
filtration chromatography using sephacryl S-300. The active parts were
lyophlizated (free drying) to obtain Lipoxygenase with 43.18% yield and 8.16
folds of purification and specific activity of 1162.9 unit / mg.
The purity of enzyme was confirmed by poly acryl amide gel
electrophoresis under non denaturing conditions, with the appearance a single
band .
The enzyme was characterized by the following: Its molecular weight was 97
KD as estimated by gel filtration, iso electric point was at 6.2. The result
showed that it was a glycoprotein with a carbohydrate content of 13 % as
determined by phenol –
sulfuric acid method.
