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.

Research summary
تتناول هذه الدراسة فعالية عدة بدائل لبروميد الميثيل في تعقيم التربة وتأثيرها على كثافة النيماتودا ونمو نبات البندورة وإنتاجيته تحت ظروف البيوت البلاستيكية في بانياس خلال عامي 1999-2000. تضمنت المعاملات بروميد الميثيل، الدازوميت، التبخير الحيوي (مادة عضوية + تعقيم شمسي) والشاهد دون معاملة. أظهرت النتائج أن بروميد الميثيل كان الأكثر فعالية في خفض كثافة النيماتودا بنسبة 97.5%، بينما كانت فعالية التبخير الحيوي في خفض الكثافة غير معنوية ولكنها زادت من نمو النبات وإنتاجيته. لم تظهر فروق معنوية بين بروميد الميثيل والتبخير الحيوي من حيث الإنتاجية، مما يشير إلى إمكانية استخدام التبخير الحيوي كبديل مستدام لبروميد الميثيل.
Critical review
دراسة نقدية: تقدم هذه الدراسة مساهمة قيمة في البحث عن بدائل مستدامة لبروميد الميثيل، الذي يسبب تآكل طبقة الأوزون وله آثار صحية ضارة. ومع ذلك، يمكن تحسين الدراسة من خلال زيادة حجم العينة وتكرار التجارب في مواقع مختلفة لضمان تعميم النتائج. كما أن الدراسة لم تتناول الجوانب الاقتصادية لتطبيق البدائل المختلفة، وهو جانب مهم يجب أخذه في الاعتبار عند التوصية باستخدام بديل معين. بالإضافة إلى ذلك، يمكن أن تكون الدراسة أكثر شمولاً إذا تضمنت تحليلًا طويل الأمد لتأثير البدائل على صحة التربة والبيئة.
Questions related to the research

A study of effectiveness of methyle bromide (MB) and two of its alternatives were carried out to evaluate their impact on soil sterilization, the density of nematode and on the growth and production of carnation crop. The experement was carried ou t in two plastic houses of 400m2 in Zabadani region during 1999-2000.The treatments were as follows; MB(28g/m2), metam sodium (75cm3/m2), soil steaming and control. The results showed significant-differences between the control and the treatments, where the effectiveness of reducing the density of nematodes were 55.6%, 53.4%, 69.9% and 0% respectively. The soil steaming treatment encouraged the plant vigour and harvest started earlier, but the average number of carnation flowers for the different treatments were 28.3, 23.9, 32.8 and 23.8 (flowers during each harvest day) respectively. Confirmed differences were found for yield, where the highest number of carnation flowers were found in the plots treated with metam sodium, and therefor we recommend using metam sodium as a part of integrated pest management program of nematodes in carnation cultivatar.
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.
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 con trol, in reducing the infection and the reproduction rate of the root-knot nematodes M. javanica on tomato (var. Bestona) in pots.
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.
This search was carried out in Abi Garash farm, Faculty of Agriculture, Damascus University to study the efficiency of using “Agerton” as a fertiliser; either by irrigation or a foliar spry on tomato seedling. Four varieties were used (Astona, Tyr ad, E26 and Local). Results showed that the treatment by the fertilizer resulted in an increase in growth thorough the plant length increasing. This increase was about 1.1 and 1.2 folds for all varieties and types of treatment (irrigation and foliar spry), as compared to the control. Moreover, the using of fertilizer led to a significant increase in the yield of plant, which increased by 1.2 and 1.5 in Astona; 1.2 and 1.4 in E26, 2.2 and 2.3 in Local and 1.5 and 2 in Tyrade, for the treatment of irrigation and foliar spry, respectively.
