Abstract

This research was carried out at Al-Ghab, Hama Province, during the two agricultural seasons 2016 and 2017, to study the effect of some rootstocks on productivity quantitatively and qualitatively. The experimental design was randomized completely blocks design. The hybrid muskmelon Palmeta F1 was grafted on three rootstocks namely; Forza F1, Jawad F1, and Lagenaria siceraria. Mol, in addition to the control, and each treatment replicated 4 times. The results showed that grafting contributed to a significant increase in the average of total productivity and marketing, which attained the highest values in the plants grafted on pumpkin rootstock  Lagenaria siceraria. Mol (5.85, 5.29 tons/dunum) compared to the control (2.33, 1.98 tons / dunum), respectively. Also, the grafted plants showed a significant increase in the thickness of the cortex, the size of the seed cavity and the firmness of the fruits. The chemical content of the fruits showed a significant decrease in the ratio of dry matter and total soluble solids of the plants that were grafted on the Jawad F1, and pumpkin Lagenaria siceraria. Mol rootstocks compared with the control and the plants that were grafted on Forza F1 rootstock. While the fruits of the grafted plants had high content of vitamin C compared to the control which gave the lowest value (12.49 mg/100 g).

Abstract

This research was conducted during the period (2015-2017) as a part of project included in the Cooperation Agreement between the Ministry of High Education and the General Commission of Agricultural Scientific Research (GCSAR) and was funded equally by two participating sides, in order to study the impact of the organic production system on soil properties and productivity indicators of olive variety “Doebli” in two sites: Moseif and Safita, the orchard in each site was divided into two plots with an area of 1 dunum. The first one is managed under the organic system according to Syrian Organic Law (sheep manure fertilizer: 2 tone/dunum, green manure grass pea: barley 9:1 in rate of 15 kg/dunum, excessive pruning in the year of heavy production and 3 tillages per year), while the second part was managed under the conventional practices used by farmer (chemical fertilizer NPK, Urea 46%: 500g/tree in two patches in March and April, potassium sulfate 50%: 300g/tree in March, superphosphate 45%: 300g/tree in November, balanced pruning, 5 tillages per year), and the two plots were separated by two lines of trees. The soil analysis was carried out before and after the organic and conventional treatments, as well as some indicators of productivity (the length of recent vegetative shoots, sex ratio and fruit set ratio). The results of soil analysis at the two sites showed that the organic treatment was significantly higher than its conventional counterparts in terms of organic matter, total nitrogen, phosphorus and potash. The effect of the experimental treatments appeared increasingly at the end of the second season, these elements were gradually released as a result of the fermentation of manure and green manure, and the release of organic acids in the soil. It was observed that the organic treatments were superior to the conventional ones in term of the length of recent vegetative growths (7.32, 3.39 cm, respectively), and the number of flowers per inflorescence which was 14.73 in the organic treatment compared to 12.53 in the conventional one, so the difference between the two treatments was significant, the superior revealed also in the sex ratio (2.74 and 2.11, respectively) and fruit set ratio (4.71 and 3.8%, respectively). This study confirmed the positive effect of the organic production system in improving the olive farm environment and the soil, in order to achieve more yield and production sustainability in farm by using safe and healthy environmental methods.

Abstract

The research was carried out in Dahr Al-Qusair Region-Homs during three successive seasons 2015, 2016 and 2017 on Golden delicious trees, to demonstrate the effect of summer pruning on two different periods on the productivity of pruning trees in the next season, and on qualities of fruits. The results showed that the last ten days of July had insignificant differences compared with other dates in increasing the production of trees. The average of production reached 61.67 kg in the first season and 70 kg in the next season. The results showed also, that there were insignificant differences between the three dates in their impact on firmness and TSS of fruits.

Abstract

A field experiment was carried out at the field station of the village of Bounouara in Constantine, Algeria, during the agricultural seasons 2016/2017 and 2017/2018, with the aim of studying the impact of four agricultural dates (14th November, 1st December, 2nd January and 17th January). Seven soft wheat varieties (Plateaus, Cedar, Ein ebeid, Arhamocho, Tides, Masin and Pomerzov), according to the design of split plot with three replicates. The results showed that agricultural traits had a significant effect on the phenological stages, plants height and grain yield and its components. The results showed that the decrease in blooming stage in a percentage of 22.52% led to a decrement in plant height (20.81%), number of spikelet (14.02%), number of kernels (12.53%), 1000 kernel weight (10.92%) and grain yield (69.96%). The varieties differed within each other, where the variety Plateaus was the most adaptability and stability one in Bounouara with a grain yield of 4456 Kg/ha. The study recommends taking into consideration the life cycle of wheat varieties when grown, where at the early dates the long-life wheat varieties should be sown, and vice versa.

Abstract

This research was carried out at the Agricultural Scientific Research Center in Sweida, GCSAR during the growing seasons of 2015 and 2016 to study the effect of number of foliar sprays of boron on the productivity and qualitative characters of Golden delicious apple cultivar. Boric acid foliar spray (1 g.l-1) was added for once, twice or three times besides the control (without addition). The results showed that, the average of productivity increased significantly when spraying three times of the boric acid, in the two seasons (69.35 kg/tree and 125.1 kg/tree respectively), while the average yield in the control treatment was the lowest compared to other treatments (43.53 kg/tree and 59.73 kg/tree respectively). The average grading of the fruit were; excellent, first, second, and third under the addition of foliar spray for three times with boric acid and soil fertilizer addition (6.06%, 60.74, 32.54%, and 0.66% respectively), but the grading percentage  under the addition of foliar spray for twice with the soil addition of fertilizer were 4.56%, 57% , 37.61% and 0.83%, respectively, while  under the control treatment the grading percentages were 0.79%, 26.23%, 57.76% and 15.22%, respectively. It was concluded that the application of these factors contributed in the increase of the average productivity and improved the quality of the fruits.

Abstract

This research was conducted to determine the effect of covering rows with two types of transparent and black polyethylene on the growth and productivity of two genotypes of eggplant (Alwardi and Black) under the conditions of Bseren, Hama government, Syria during 2014 season. Split plots design was used in this experiment, with three replications. The results showed that covering rows with polyethylene has a positive effect on the vegetative growth of eggplant in comparison with the control. This was reflected positively on production and early maturity. Eggplants genotypes that were covered with transparent polyethylene exceeded significantly the other eggplants genotypes that were covered with black polyethylene in all the studied traits. The early maturity was clear for covering plants with both transparent and black polyethylene slices in comparison to the control during the first month of picking up fruits. Both treatments of covering exceeded the control in terms of productivity by 46.14% and 20.41%, respectively.
