نفذ البحث في حقول شعبة بحوث البستنة والغابات ،قسم البحوث الزراعية في نينوى ،خلال الموسمين ربيع ( ١٩٩٤ ، ١٩٩٥ ) لدراسة تأثير ثلاث مسافات زراعية بين نباتات اللوبياء و هي ١٠, ٣٠ ،٢٠ سم و أربعة مستويات من السماد الفوسفاتي ٧٥ ،٥٠ ،٢٥ ،٠ كغم ٥دونم. /P٢O.
The experiment was conducted at the vegetable research farm, Depart.of Hort. and Forst. Resea., Nenivah during the growing season of ١٩٩٤ and ١٩٩٥. The objective of the research was to investigate the effect of plant spacing (١٠, ٢٠, ٣٠ cm) and phosphorus fertilizer (٠, ٢٥, ٥٠, ٧٥ kg.P٢O٥/donum),on yield and other related traits of Cowpeas.

This study was conducted to evaluate the effect of seed Rhizobia-treating
and Cowpea severe mosaic virus (CPSMV) inoculation on bacterial nodulation
and nitrogen fixation in cowpea. CPSMV was isolated from infected plants,
College of Agriculture,
Abu-Ghraib, Baghdad, IRAQ, the Rhizobia was isolated
from nodules on roots of cowpea plants. The plants were inoculated by the
virus 2 weeks after germinations. Nodules on roots of Rhizobia-treated plants
were formed while no nodules were observed on non-treated ones. The mean
number of nodules was 24.93\ plant on virus inoculated plants compared to
59.86 nodules\plant on non-inoculated ones. Significant reduction in nodules
weight was induced by the virus, 0.62 gm on the virus inoculated plants
compared to 2.13gm on non-inoculated ones. It has been found that the
Rhizobia induced significant increase in nitrogen percentage at p=0.05 in the
foliage, 1.29% in plants non-treated with Rhizobia non-inoculated by the virus
compared with 2.502% in Rhizobia treated-virus inoculated plants and 2.550%
in Rhizobia treated non inoculated plants. The virus caused an increase in
nitrogen percentage, 1.877% compared to 1.29% in non-inoculated plants. The
Rhizobia caused an increase in pods number\plant, seed number\plant, and seed
dry weight (gm)\plant, 25.6, 114, 32.4 compared to 12.8, 70.6, 8.7 in non-treated
plants respectively. The treatment of virus inoculated plant by Rhizobia
induced a significant increase in these values, except with nitrogen percentage
in seeds, 16.4, 84.6, 10.4, 4.3 respectively.
نفذ البحث خلال الموسم الزراعي (2014) م في الساحل السوري في محافظة طرطوس لدراسة تأثير أربع كثافات نباتية وثلاث مستويات من الأسمدة
This research was conducted during the growing season of 2015 at
AL-Arema village of governorate Tartus, to study the effect of
three spray bio-fertilizer times (1- flowering stage. 2- pods
formation stage . 3- seeds formation stage), and four rat
es of biofertilizer
(zero, 2 cm3/liter ,4 cm3/liter,6 cm3/liter) in the growth and
productivity of peanut crop.
The experiment was designed by using Split-plot design three
replications.
The lack of information about the cultivation of coriander plant in Syria prompted us
to study the effect of four plant densities (33.33،10، 13.33 and 20 plant/m2)، and four levels
of phosphate fertilization (0107.2،160.8، and 214.4 of Superphospha
te 46%) on some
productive and quality traits of the coriander plant. This study was carried out in Tartous
province during the growing season 2014، using Randomized Complete Block design with
a Split Plot arrangement of treatments. The Results revealed that there were significant
differences between the treatments for the whole traits، in addition to a significant
interaction between density and phosphate fertilization. Although the densities (10، 13.33
and 20 plant/m2) varied in their effect، they had superiority upon the
control(33،33)plant/m2، and the density 10 plant/m2 had more important effect in terms of
increasing each of: branches number/plant، seed weight/plant، seeds number/inflorescence،
protein content in plants and seeds and beta carotene and chlorophyll. However، the level
160.8k.g/h of P2O5 increased the number of inflorescences/plant، number of fruits/plant
and seed weight/ inflorescence.
This research was carried out through 2015-2016 growing season
belongs to the fourth stability at Gander village located on the
between Homs and Damascus .The aims of this research were to
study the effect of plant density on seed yield and its components
of faba bean (vica faba ) and to investigate the optimum plant
density of this crop in the region.
