Abstract: 

This research was carried out in the Scientific Centre for Agricultural Researches in Lattakia. This study was conducted with the aim of studying the effect of some treatments on the percentage of seed germination of Laurus nobilis L. and The effect of the agricultural media on the percentage of germination, growth, and development of seedlings. The seeds were treated with several different treatments: Control; and moist cold Stratification; Gibberellin soaking; concentrated Sulfuric acid  (H2SO4); and Scarification treatment; in addition to using several media: Turf, Nursery soil, and a mixture of turf and nursery soil. The results showed the success of the moist cold stratification method for two months and its superiority in raising the proportion of germination to 98%, Germination speed and homogeneity were improved. However, the treatment of seeds with mechanical scarification came second and gave a germination rate of 78.67%. The treatment of seeds with gibberellin at a concentration of 300 ppm gave a good germination rate of 53.33%. In the case of the treatment of Laurus nobilis seeds with concentrated sulfuric acid, germination was inhibited. Moreover, it clearly showed the positive effect of Turf in improving the percentage of germination and the values of the indicators measured during the process of mixing it with the soil of the forest nursery used for the growth of seedlings.

Abstract: 

These Experiments had been done in The Agricultural Scientific research Centre in Lattakia, where 24 Types of red and green Okra were Collected from different altitudes (25 – 650) meters. This work Continued for 10 years (2006-2016). These types were planted within an experimental pieces of 11.2 m2 square, and the distance between each piece and another is 50 meters in order to reduce the Cross-pollination. Both of the general and the special Criterions had been considered during the individual plant Selection. During the first and the second years of the Selection, the bad and strange plants had been removed, 12 types out of 24 were selected. Then, in the next two years, individual plant selection had been lasted after covering the selected plants of every type with mosquito net in order to reduce the Cross-Pollination among the types. In the third and fourth years of the Selection, only two types out of twelve were selected; one of them had green pods and the other had red pods. Individual plant selection had  been lasted more over 4 consecutive years until plants had become  identical, with wanted qualities, and high productivity. The two selected types were compared with 3 okra varieties (OK 100, suzie F1 and lady finger). The yield of the two selected local types (421.7 and 415 g/plant) were better than suzie F1 and Lady finger (191.6 and 262.8 g/plant), whereas no significant differences were observed between the local types yield and  OK 100 yield (336.5 g/plant).

Abstract: 

The research was carried out at the General Commission for Agricultural Scientific Research, Rural Damascus Research Center (Sarghaya and Al-Taybeh Research Stations), during the two agricultural seasons 2019 and 2020, with the aim of studying the effect of environmental factors of the sites where saffron plants (Crocus sativus. L) were planted on the vegetative and flowering growth indicators of plants. The results of the experiment showed that the prevailing climatic conditions in the Sarghaya region increased the indicators of vegetative growth (average length and number of leaves, average number of shoots) and flowering (average number of flowers and their wet weight, average length of stigmas and their dry weight) of saffron plants grown in them compared to their counterparts grown in the conditions of Al-Taybeh region—statistical indications for both seasons. The 2020 season was significantly superior in average leaf length, average number of leaves, average number of shoots, average number of flowers, and average wet weight of flowers (29.36 cm, 160.4 leaves, 6.63 growth, 0.6333 flowers, 0.2193 g) over the 2019 season, while the latter outperformed the 2020 season. With statistical significance in the average length of flower stigmas and dry weight of stigmas (3.592 cm, 0.035 g), the superiority of the second season in most of the studied traits is attributed to the increase in the number of corms per unit area resulting from the mother corms planted in the first season.

Abstract: 

The research mainly aims at the descriptive economic analysis of the costs and revenues of durum wheat production (Baal) in Lattakia Governorate, and the study and analysis of economic indicators related to the economic efficiency of the agricultural season (2023-2024). The initial data was collected through a questionnaire targeting a sample of wheat farmers amounting to 370 farmers, the size of which was calculated according to the Stephen-Thompson equation. The results showed that the average annual net profit achieved from a durum planted with durum wheat (Baal) was 1.5 million SYP/dunum/year, while the profitability coefficient compared to invested capital was 64%, and compared to production costs was 71.4%, which is considered a very good indicator in the field of agricultural investment, as the profitability rate is equivalent to about 71 SYP, for every 100 Syrian pounds invested annually. The variable assets turnover rate was 1.93, which is evidence of the efficiency of investing available resources and increasing productivity. The results also showed that the economic efficiency index was 1.71, which is greater than one, indicating efficiency. Exploitation of fixed and variable capital, and the feasibility of producing durum wheat (rainfed) in Lattakia Governorate. The study concluded that there is a need to increase interest in wheat cultivation, while encouraging and motivating farmers to increase the areas planted with this crop, given the economic savings it brings to rural families, diversifying sources of income, and improving their standard of living.

Abstract: 

The study aimed to measure the consumers’ awareness level of the source and safety of agricultural products, as a case study for workers at Al-Swaida Scientific Agricultural Research Centre. Presuming that the studied statistical community includes all types of working of administration, research and services areas, surveying methodology was used with about 170 singular samples, 2021/2022. The results showed four classes of consumers’ awareness levels, weak, medium, good and very good awareness levels. The highest percentage of the obtained results was 48.24% for the third class (good awareness). Factors affecting the awareness level were defined using different correlation factors that suit the variables. Based on that, the alternative assumption of having significant statistical differences between the awareness level and the variables of gender, capacity building, reading about food safety, family individual status, the obtained scientific degree, and consumers’ length in cm, the percentage of the individual’s income that spent for food was accepted. It was clear from the suggested ordinal regression model that variables of capacity building, reading books, scientific degree and the consumed percentage of the monthly income on food have a predictive significance on the individual awareness level. Since variables of capacity-building, reading books and scientific qualifications have a positive impact, individuals following training on food safety, buying books and enhancing their scientific qualifications will increase the poten-tial of existing in a higher awareness level of the suggested classes. In contrast since the variable of the consumed percentage of the monthly income on food has a negative impact, thus the higher this percentage the higher the potential to exist in a lower awareness level of the suggested classes.

Abstract: 

Yellow rust is one of the major factors that affects in the bread wheat production in Syria. The study was conducted at the Al-Jamasa Research Station of the Scientific Agricultural Research Center in Tartous during the two seasons (2021/2022) and (2022/2023), with the aim of evaluating and selecting promising lines of Bread wheat that tolerant to yellow rust caused by the fungus Puccinia striiformis West. f. sp. tritici Eriks under natural infestation conditions of the yellow rust fungus community for yield components (spike length, number of grains/spike, grain weight/spike and weight of 1000 grains) in addition to its resistance to yellow rust disease. The study showed an improvement in the yield components characteristics of the three cultivated cultivars (Cham6, Cham8, Cham10), in addition to improving their resistance to yellow rust disease, by selecting promising lines resulting from crossing them with resistant genotypes. (47) Promising lines were selected with high yield characteristics in addition to their resistance to the disease. Seven promising lines (38, 39, 60, 70, 82, 95, 184) resulting from four crosses (Cham10× Babacha), (Cham8× Babacha), (Cham6× Babacha), (Avocet yr15× Babacha), respectively, showed a tolerant reaction to yellow rust disease. The 7 lines (56, 57, 63, 83, 94, 97, 101) were also characterized by the highest average spike length and number and weight of grains/spike. as were the 12 lines numbers (111, 122, 132, 133, 140, 144, 145, 146, 147, 148, 149, 150) resulting from selection within isolated populations of the cross (Avocet yr5×Cham8) with higher averages for all yield traits studied, which shows the importance of genetic resistance to yellow rust in maintaining yield traits.
