Effect of Varieties sowing dates and density on the green pods yield of pea in Hama

The research was conducted during the growing season in 2013- 2014 in Bssiren Hama. In a split- plot design: the varieties were main plots (asgro, rama, Muncipal) and the sowing dates were subplots (15\11;30\11;15\12 and 30\12) and the densities were subplots (20 plant\m2, 13.33 plant\m2). The early planting went to Significant increase in the days to germination, long time of fruit; the number of days to flowering and the number of days to fruiting; Plant height; Number of branches plant ; weight of pod; number of pods plant; dressing percentage; Yield of green pods plant and Yield of green pods. While the high density was observed Significant increase in the Plant height; Number of branches plant; weight of pod; number of pods plant; and Yield of green pods plant, while the low density was observed Significant increase in the Yield of green pods. The Asgro variety was obtained at Rama and Muncipal varieties in the number of branches plant; number of pods; Yield of green pods plant and, while the Rama variety was obtained by the plant height, and non- significant results were found among varieties by the weight of pod. The positive results also showed in the interaction among factors.

Effect of Plant Density on Productivity of some Sweet and Hot Pepper Hybrids in Plastic Greenhouse

The study was conducted in Jableh during 2012/2013 in plastic green house on sweet and hot pepper hybrids to study the effect of plant density on growth and productivity. The hybrid VIGARIO(sweet pepper) and hybrid ERAD (hot pepper)variety were applied in six treatment and four replication .It was showed that the highest number of flowers were recorded in VIGARIO variety in space (50x60)cm to amount(18.33) flower/plant ,while the the highest number of fruits were recorded in space(50x40)cm to amount(20.98)fruit/plant and the earlest yield (390.6)g/m2and the highest total (3486)g/m2productivity were found in space (50x40)cm . IRAD hybrid give the highest number of flower in space (50x40)cm to amount(28.23) flower/plant,while the hieghest number of fruit were recorded in space (40x60)cm to amount(107.17) fruit/plant and the highest productivity were found in space(50x40)cm to amount (9485.7)g/m2.

"Studing the growth and productivity of planted Pinus pinea L. in DAHER AL SORANI forest site in Tartous (Syria)

This research aimed to evaluate the growth and productivity of planted Pinus pinea in pure stands at "DAHR AL SORANI" forest site. The site is about 50 km north east of Tartous city, which is located in Temperate-Humid Bioclimate Zone. Results showed that the stands were not equivalent in growth indicators; this was due to many factors affecting growth like site characteristics and trees density…etc. In spite of the mediocre values of form factor, the volume and mean of annual increment was not influenced. Results revealed that the mean values of tree density was 851 trees/ha and ranged between 350 - 1975 trees/ha, woody volume was averaged at 116.337 m3/ha and ranged between 51.6519 - 215.3635 m3/ha; annual increment had also an average of 4.4548 m3/ha/year and ranged between 1.9866 - 7.9764 m3/ha/year. The study showed a high straightness of pine. Pinus pinea trees had very rarely forked boles.

Study of Palaeomagnetism and Some Magnetic and Physical Properties of Some Tertiary Igneous Rocks between Sana’a and Al-Hudyadah Region (Republic of Yemen)

Palaeomagnetism and some magnetic and physical properties (magnetic susceptibility, intensity of the Natural Remnant Magnetization (NRM), ac current electrical conductivity and density) of 136 samples from 22 sites of the Yemen Volcanic Group TKY (Tertiary and (or) Cretaceous) from igneous rock exposures along the road from Sana’a – west towards Al-Hudyadah were studied. A single population consists of seven Virtual Geomagnetic Poles (VGP), of the Upper Oligocene, was accepted and a mean at 182.81° E, 77.44° N with α95= 12.5° was calculated. The different properties were measured in order to use these properties as characteristic factors to discriminate the neighboring igneous flows. The measurement of the in situ magnetic susceptibility of 140 points, distributed on 7 sub-areas, in the region helped to calculate the mean value of the magnetic susceptibility of each sub-area, which might be used in any magnetic interpretation of aeromagnetic or magnetic anomalies. Also, the density of 132 samples were measured and a mean value of the density of each sub-area was calculated in order to be used in any future interpretation of any gravity anomaly in the area.

Dating and Correlating Some Syrian Basaltic Rocks by Using Some of Their Magnetic Properties

Palaeomagnetism and some magnetic and physical properties (magnetic susceptibility, intensity of remanent magnetisation, ac current electrical conductivity and density) of many basaltic samples were studied.

Palaeomagnetism and Some Magnetic and Physical Properties Studies of Upper Pliocene Basaltic Rocks ( West of Homs - Syria)

Palaeomagnetism and some magnetic and physical properties such as magnetic susceptibility, intensity of remanent magnetisation, ac current electrical conductivity and density for the number order (٣٩ - ٥٤) of samples from ٩ sites of Upper Pliocene basaltic rocks from the area west of Homs were studied. The aim of the works to extend the previous studies (Abou- Deeb, ١٩٩٧a, b) to other regions so that these properties might be used as characteristic factors in discriminating the basaltic flows.
