Abstract

This research aimed to study the vegetation cover changes at AL-A brash Basin River using Normalized Difference Vegetation Index (NDVI), Geographic Information Systems (GIS) and remote sensing (RS) as well as to estimate plant factor(C) depending on NDVI for the year 2018. satellite images were used for the studied area, these images were captured by Landsat 8 OLI (Operational Land Imager) which was taken on October in (2013-2014-2015-2016-2017-2018). as well as images were taken in 2018 that representing (January, April, November). The results showed that vegetation cover was the best in 2015 with high NDVI value of 0.59, while the vegetation cover in 2016 began to deteriorate and then this deterioration later increased in 2017as that value of NDVI reached 0.48. The seasonal changes that affected on vegetation cover in 2018, showed that NDVI value in spring reached to 0.56 which is higher than it in Autumn and winter, the reason is due to the herbal cover which is completed in spring. For the vegetation factor C calculated based on the NDVI index for 2018, its value ranged between (0.24-1.23), as its value decreases in areas with good vegetation coverage. Finally, this study can be an instrument for understanding the behavior of NDVI and its temporal and spatial changes; which may help using it more precisely in many studies. \

Abstract

The development and optimal use of water basins is one of the successful solutions to improve the water status in the water basins.Selqin Basin, which is a part of the Northern Orontes Basin, was selected with the aim of locating and designing a dam in order to improve the management of water resources and to achieve basin sustainable development. Topographic maps, slope maps, climate data for the hydrological years (1977-1978) and (2011-2012) were used for this purpose. The GeoMedia professional 6.1 and Excel programs were used to determine the best location of the dam. The results showed that the best location for the construction of the dam is about 4.5 km west of the city of Salqin, and by studying the relationship among the potential height of the dam body and both of the lake surface and its length and the distance between the two sides of the valley, depending on the average rainfall and the great intensity of the rainstorms, the size of the dam lake was determined with 1.7 million cubic meters filled within one year, on this basis the dimensions were 16.98 meters high, 6.8 meters top wide, 23.8 meters base width, in addition to the length of the dam body at the top was 251.6 meters.

Abstract

This study was carried out on clay soil in Yahmoor, Tartous city, on potato (cv. spunta) during (2017 and 2018) to investigate the effect of tillage type and depths on some hydro-physical soil properties included (water infiltration rate, moisture content) and on productivity of potato plant. Randomized Completely Block Design (RCBD) arranged according to split-plot with three replicates was used. The field was divided into two main plots represented the types of tillage :(Moldboard plow MP and Chisel plow CP). The main plot was divided into three secondary plots which represented tillage depths included: D1(0-10) cm, D2(10-15) cm and D3(15-25) cm. The results showed that mold board plow increased significantly water infiltration rate (15.36, 10.41 mm/hour) after month and four months of tillage compared to the chisel plow, while chisel plow increased moisture content (19.39, 16.83%) after month and four months of tillage compared to mold board plow. D1 and D2 significantly increased water infiltration rate compared to D3 which significantly increased moisture content compared to D1 and D2. The results showed as well, that all tillage treatments increased productivity of potato plant. Inversion tillage with moldboard plow at D2 and D3 depths increased significantly potato yield (4358.83,4419.22 kg/donom) of potato tubers with tow treatments respectively.

Abstract

34 Shami cows were used in Deir Al-Hajar Research Station to breed Shami cows to analyze the data of the udder dimensions during the year 2019 to know the effect of the morphological specifications of the udder in the milk production of the Shami cows in Syria and to estimate the phenotypic relationships between the udder dimensions with each other and with the total milk production. The results showed that there was a significant effect (0.05≥p, 0.001≥p) of the arrangement of the mother’s lactating cow season in milk production with the development of the production stage and total milk production, where the average total milk production was 1264.71 ± 87.19 kg and 10.90 ± 0.40 kg / day and 7. 90 ± 0.90 kg / day and 4.04 ± 0.70 kg / day according to the development of the productive stage, and the results showed a significant effect (P <0.01) of the arrangement of the mother’s cow season in the characteristics of the length, width, depth, circumference and size of the udder for the ewe and with the development of the productive stage where Multi-season cows (more than one season) through the fourth year outperformed the first season’s cows, the highest of which was the fourth season’s cows, and in terms of measuring height On the ground, the first season cows outperformed the multi-season cows. The results also showed a significant effect (P <0.01) of the cow season’s ranking in total milk production, the highest of which was the fourth season’s cows (1352 ± 26.53 kg), and the lowest of the first and second season cows reached (1197 ± 22.72, 1163 ± 26.53 kg) respectively. The results indicated that there was a correlation relationship (P <0.01) between the characteristics of the udder measurements of the length, width and circumference of the udder before and after milking and the mean lengths, widths and circumferences of the udder, with the total amount of milk, as it reached (r = 0.50, r = 0.26, r = 0.41), (r = = 0.20, r = 0.30, r = 0.25), (r = 0.21, r = 0.30, r = 0.25) respectively, and the results showed a correlation relationship (P <0.01) between the length of the udder and measurements of width, depth, circumference, and size of the udder before and after preparing Milking and average these measurements with each other.

This study was conducted to assess performance, combining ability, heterosis and gene action for 15 single crosses of maize (Zea mays L.) and 8 parents (5 lines and 3 testers) in line x tester analysis at Raqqa governorate in two locations; Raqqa Research Center (RRC) and Ali Baglih Research Station (ABRS), Syria, in 2013. The experiment was arranged in a randomized complete block design with three replications. The results showed highly significant differences among genotypes for all traits, also, between parents for all traits. Most of the parents were early flowering except IL.175-10. Two hybrids IL.179-09×IL.356-10 and IL.19-09×IL.356-10 were recorded the best earliness at two sites. Results of mean grain yield performance showed that crosses IL.179-09×IL.356-10, IL.175-10×IL.356-10 and IL.179-09×IL.1-10 were the best at RRC location with means of 10000, 9790 and 9704 kg/ ha, respectively; while at ABRS location, the crosses IL.175-10×IL.356-10, IL.179-09×IL.356-10 and IL.5-09×IL.1-10 were the best with mean grain yields of 8804, 8381 and 8365 kg/ha, respectively. Combining ability analysis showed that additive gene effects were found to be important for inheritance of ear diameter and grain yield while that traits days to 50% silking and ear height were controlled by non-additive gene effects. The lines IL.175-10 and IL.179-09 , and tester IL.356-10 showed the best general combining ability (GCA) for grain yield, earliness and other traits at two sites. The lines IL.5-09 and IL.179-09 and, the testers IL.356-10 and IL.1-10 showed the best GCA for short ear height, while the lines IL.175-10, IL.27-10 and IL.1909 and, the tester L.134-10 showed positive GCA effects for ear height. Assessment of significant positive SCA effects and heterosis for grain yield revealed that crosses IL.179-09×IL.356-10 and IL.175-10×IL.356-10. The cross IL.356-10×IL.179-09 showed the best association between performance, SCA effects and heterosis for the grain yield and earliness, could be used in different environments in Raqqa governorate. Results of potency ratio indicated that inheritance of grain yield was controlled by over dominance, while inheritance of other traits was controlled by partial, complete and over dominance in some crosses.
