Economic efficiency of peanut production in the Syrian coast

The research was carried out in the Syrian coast (Lattakia and Tartous governorates). The aim was to identify the economic efficiency of peanut growing by applying the economic efficiency measures for agriculture and its most important indicators. The research requirements, based on a questionnaire, were randomly distributed to( 377) crop growers in the study area. Twenty villages were selected from four regions (Lattakia, Jablah, Tartous, Banias) In the two governorates mentioned above, during the agricultural season (2016-2017). The research was carried out based on the prices of 2017 and compared with the prices of 2010, where prices, costs and wages were adopted at the time of their expenditure, from the time the land was prepared and prepared for agriculture to production and marketing.

Effect of Peanut Seeds Size and Plants Spraying with Bread Yeast (Saccaromyces sereviciae) on Biological Crop and Some Productivity Indicators

The research was carried out during 2015 and 2016 seasons at Arab El-Mulk village, Banias district, in Tartous Governorate, to study the effect of planting peanut seeds size (mixture, small, medium and large), and spraying plants with bread yeast (Saccaromyces serevisiae) concentration of (4%) in three treatments (control, once and twice), on biological yield (BY), Economic yield (EY) and some physiological indicators; yield index (YI), Harvest index (HI), crop index (CI) and seed index (SI). The experiment design was set as split plot in a randomized complete block with four replications. The seeds size considered the main factor, while spraying yeast allocated the sub plots. The results showed that seed size caused significant increases in all of the studied indicators. The large seeds gave better values of (BY) 210 g, (HI) 30.56%, (CI) 44.12%, (SI) 74.85 g, except (EY) compared with mix, small and med seeds. Also the results showed that there were no significant increase between mixture and medium seed size in (YE) and (HI), but there was a significant increase in (BY) and (SI), on the other hand the treatments; spray yeast for once and twice had significant increases compared to the control, and the twice yeast spraying gave better values (215.22 g ,63.98 g, 29.64%, 42.37 % and 73.45g ) of (BY , EY ,HI, CI and SI) respectively, compared to the control. The interaction between seeds size and bread yeast spraying caused a significant increase which achieved 15.78 % in (BY), 23.99 % in (EY), 9.74 in (HI), 13.68% in (CY) and 7.87g in (SI) compared to the interaction between untreated treatment and small seeds size.

Effect of using non - conventional and traditional organic wastes on some physical properties of clay soil and peanut productivity in Akkar Plain

This research was conducted in 2016c, at the Zahid Western Research Station in Akkar Plain region of Tartous Governorate, the objective of this research is study the effect of non-conventional organic waste (compost of garbage, sewage sludge) and cow manure on the physical properties of clay soil in the region. Wastes was added to the soil at a rate of (0 - 10 - 20 – 30) t/ha, in order to determine the effect of the difference in the quantity added on physical properties of the soil and peanut productivity.

Economics of Using Irrigation Water in the Cultivation and Production of Peanut Crop (Arachis hypogeae) in Syria

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.

The Effect of Drought Stress on Growth and Yield of Peanut Crop in Tartous

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).

Effect of Sowing Date and Nitrogen Fertilization on Several attributes of groundnut ( Arachis hypogae L. )

This search was conducted in Albassa town at Lattakia governorate , during 2011 and 2012 growing seasons for study effects of 3 sowing dates ( 15th of April , 25th of April and 5th of May ) and 4 levels of nitrogen fertilization ( N1: control , N2: 50 kg/ha , N3: 100 kg/ha , N4: 150 kg/ha ) on several attributes of groundnut (Coastal category) production . The results showed that the 5th of May sowing date had significant excel in the average of the two growing seasons in dry weight of pods in plant , wheight 100- Seeds, The per-hectare yield of seeds and Harvest index , It ranked first in the two seasons search. Also, The application of nitrogen fertilizer at a rate of 150 kg/ha had resulted in a significant increase in studied productivity traits in the average of the two growing seasons , Except for harvest index , which was at least as compared to other levels of fertilization. The interaction between the sowing date ( 5th of May ) and the level of nitrogen fertilization (150 kg/ha) showed a significant excel in the average of the two growing seasons in dry weight of pods in plant , wheight 100- Seeds and The per-hectare yield of seeds .

A Study Some Physiological and productive Parameters for Peanut Cultivars under Effects of Row Spacing and Number of Plants per Hill

The search was conducted in Dabba site for Agricultural Scientific Research at Lattakia region in the growing season 2011 to study some physiological and productive parameters for peanut cultivars under the row spacing effect and number of plants per hill, the experiment was designed by using split-split plot design with three replications. The treatments of experiment included four cultivars of peanut (ICGV 92022, C16 local 262, Souri, Al-Baladi) and three row spacing (40, 60, 80 cm) and two levels of number of plants hill-1 (one plant hill-1, two plant hill-1).

Effect of Row Spacing and Number of Plants per Hole on the Yield and Yield Components for Some Peanut Cultivars under Local Conditions

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

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 .
