نفذ البحث لمقارنة كفاءة الزراعة المسبقة بصنف بندورة حساس OXN93 كنبات صائد مع استخدام مستخلصات كل من ثمار الأزدرخت و أوراق الأوكاليبتوس و نبات الشوكران الكبير بطريقتي السقاية و الرش على المجموع الورقي مقارنة باستخدام مبيد الديازينون كشاهد معامل و ذلك في تخفيض الإصابة و تخفيض معدل التكاثر لنيماتودا تعقد الجذور من النوع Meloidogyne javanica على نبات البندورة من الصنف الحساس Bestona ضمن الأصص.
This research has been applied to compare the efficacy of the use of pre-planting with a sensitive variety of tomato OXN93 as a trap crop with the use of the extracts of M. azedarach , E. camaldulensis and C. maculatum where Diazinon a treated control, in reducing the infection and the reproduction rate of the root-knot nematodes M. javanica on tomato (var. Bestona) in pots.

A study of the effectiveness of methyl bromide (MB) and some alternatives
were carried out to determine their effects on soil sterilization, densitY of
nematode and production of tomato (variety Karam) crop, under greenhouses
conditions in Banias
area, during 1999-2000.The treatments were as follows:
MB (57g/m2), Dazomet GR 98%, organic matter + solarization (Biofumigation)
and control. Results showed that the effectiveness in reducing the
total nematode density were 97.5%, 66.1%, 28.8 and 0% respectively. The root
knots index for Meloidogyne spp. were 0, 0.64, 0.83 and 1.83 respectively. The
Bio-fumigation treatment didn't have any effect on reducing the nematode
density, but increased the plant growth and yield. The crop yield were 190.67,
167.33, 185 and 157.67.kg/plot respectively and there was no significant
difference between the MB and the Bio-fumigation treatments.
This study was conducted in order to evaluate the efficacy of the aqueous extracts
of three plants (Melia azedarach L., Smilax asepra L. and Styrax officinalis L.),
three pesticides (acetamiprid, abamectin and pyridaben) and releasing of two
preda
tors (Phytoseiuls persimilis Athias–Henriot and Stethorus gilvifrons Mulsant)
in controlling of Tetranychus urticae Koch populations in tomato greenhouse.
The research aims to study the effect of certain organic and amino
compounds in the growth and production of tomato under green
houses conditions.Hulay F1 hybrid tomato and two organic
commercial vehicles differing in composition Hupost and
Boldo
uzerwere used.The experiment done in a way randomized
complete blocks designed , with three replicates per treatment , and
10 plants per replicate . Seedlings WERE Prepared in beet moss
using trays of Alstrepor inside the greenhouses.
The experiment was carried out during2013-2014 Miaar Shaker village (Tartous) to determine the best method of irrigation on growth and productivity of Tomato plant in plastic green-house. Three method of irrigation were used in the experiment :(furro
w surface , surface drip and subsurface drip irrigation). Growth of plants, productivity and fruit quality were studies.
The results showed that surface and subsurface drip irrigation give more plant growth (leaves number and leaves area) more flowering and fruit production as compared with furrow irrigation method .The leaves number and leaves area in plant with surface drip irrigation was 31.49 leaves and 17078/plant while these number reached only to 22.91 leaves and 7057.86/plant in the furrow irrigation with significant difference . The productivity of plants was also higher in surface drip irrigation method(4.75 kg/ plant) without significant difference as compared with subsurface irrigation method and with significant difference as compared with furrow irrigation method (3.95 kg/ plant). The quality of fruits was better in surface drip irrigation (8.28% dry material ,5.02% TSS and 28.23mg vitamin c /100g) in fresh matter while these number were 7.18%, 4.98% and 20.96 mg/100g in furrow .
The irrigation method haven't affect in the: plant length ,and acidity percentage.
The experiment was carried out during spring season 2016 to study the effect
of foliar spraying treatment with Tecamin Flower 2.5 ml/L in comparison with
distilled water, on growth of three hybrids of tomatoes at two different levels of
irrigation
(100 and 50 % of field capacity). Three sprays were conducted started
from flowering with two weeks’ interval. The results showed that ‘Finenss’ hybrid
had significant differences in plant height, branches per plant and leaves number per
plant. ‘Hadeer’ hybrid had superiority in dry matter ratio and content of chlorophyll
in leaves. Reducing the level of irrigation resulted in a significant decrease in
plant height, total branches number, versus an increase in the leaves number per
plant, total leaves area and the percentage of dry matter. The results showed that
the treatment with Tecamin flower led to a significant increase in all indicators
studied. The interaction treatments shoed that Hadeer hybrid irrigated in level 50
% and spraying of nutrient solution (Tecamin flower) had a significant increase in
dry matter ratio and chlorophyll content in leaves. While the hybrid Finenss which
irrigated in level 100 % with nutrient solution (Tecamin flower) had a significant
increase in leaves number per plant and total leaves area.
