نفذ البحث خلال الموسم الزراعي 2014 في سهل ميعار شاكر بمحافظة طرطوس ، لدراسة تأثير الإجهاد الجفافي المطبق لمدة 24 يوما في أربعة أطوار لنمو نبات الفول السوداني و هي : 1- طور التفرع 2 – طور بدء الإزهار 3 – طور تشكل القرون 4 – طور تشكل البذور . بالإضافة إلى الشاهد ( ري كامل كل 12 يوما ) . و تأثير ذلك في بعض صفات النمو و الإنتاجية لصنف الفول السوداني ساحل.
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 formation 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).

This research was conducted during the growing season of 2015 at
AL-Arema village of governorate Tartus, to study the effect of
three spray bio-fertilizer times (1- flowering stage. 2- pods
formation stage . 3- seeds formation stage), and four rat
es of biofertilizer
(zero, 2 cm3/liter ,4 cm3/liter,6 cm3/liter) in the growth and
productivity of peanut crop.
The experiment was designed by using Split-plot design three
replications.
The study was conducted in order to know the ability of
Korschinskii Almonds and Orientalis Almonds to resistance of the
drought stress using several levels of water irrigation (100, 75, 50
and 25%) from the field capacity, with several indicators
(number
of leaves, the thickness of the leaves, root growth). The results
obtained showed not affected by the stock in the Korschinskii
Almonds drought stress (255, 242, 220, 198 leaves), while the
number of leaves that accompany the burning edges under the
influence of drought stress in Orientalis Almonds (250, 130, 60, 12 leaves) at levels of irrigation water (100, 75, 50, 25%) of field
capacity respectively.
A field experiment was conducted for two years 2011-2012 to evaluate the effect of various tillage implements, tillage depths and nitrogen fertilizer timing application on soil bulk density, its moisture, and peanut growth. Three different implements
were used: moldboard (MP), chisel (CP) and disk ploughs (DP). Tillage depth treatments (split-plots) included (8-10) cm, (18- 20) cm and (28- 30) cm tillage depths; D1, D2 ,D3 respectively. Timing applications (split-split- plots) were: T1 all nitrogen fertilizer applied at planting ,T2 half nitrogen applied at planting and half at flowering ,T3 all nitrogen fertilizer applied at flowering.
All tillage implements decreased soil bulk density for the tillage depth. They were for treatments (DP,CP,MP) at (0-10)cm depth (1.31,1.33,1.29) g/cm3, (1.31,1.32,1.31) g/cm3 at (10-20) cm depth and (1.36,1.37,1.35)g/cm3at(20-30) cm depth. Soil moisture increased in treatments (DP,CP) with increasing tillage depth .There was no effect of previous factors on main branches, but timing of nitrogen fertilizers (T1, T2) effected secondary branches significantly compared to T3. Moldboard significantly increased leaf area to (1.77) m2/plant compared to chisel (CP) and disk ploughs (DP). Also D2, D3 increased leaf area compared to D1. (T1, T2) significantly increased leaf area compared to T1. Interaction between timing of application and depth (D3 xT2) gave significant differences. The best value was (1.85) m2/plant for the two years.
The research was conducted in Dabba site for Agricultural Scientific Research at Lattakia region in the growing season 2011 during the period from early June to mid-October. The experiment included four cultivars of peanut (ICGV 92022, C16 local 262,
Souri, Al-Baladi), three row spacing (40, 60, 80 cm), and two levels of number of plants per hole-1 (one plant per hole-1, two plants per hole-1). The experiment was designed by using split-split plot design with three replications.
The results of the study showed that Al-Baladi variety was superior to all other cultivars in weight pods/plant (108.8 g), weight seeds/plant (56.8 g), weight 1000 seed (914.7 g) with yield of seeds reaching (3529 kg/h). On the other hand, ICGV 92022 was superior in number of mature pods (29.22 mature pod), in number of seeds/plant (53.90 seed) and in yield (3058 kg/h). Regarding the effect of row spacing, the spacing 80 cm between rows had given the highest values significantly for yield attributes in comparison with row spacing 40 and 60 cm. Yet the highest yield per unit area obtained with row spacing was 40 cm. As about the effect of number of plants per hole-1, two plants hole-1caused significant decrease in yield attributes and significant increase in seed yield in comparison with one plant hole-1
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.
