This study was carried out to survey the mycoflora of maize grain stored in the autumn season in 2011. Special attention to was paid to Fusariumverticillioides and detection of chemical analysis on the toxins Fumonisin(FUM) and zearalenone (ZEA) produced from F.verticilloides in three locations for the receipt and storage of grain in Deirezzor and Raqqa and Hasaka. The results showed that maize kernels discolored in rate of between 28.9, 32.5 and 36.4% respectively in Hasaka, Deirezzor and Raqqa. There was a positive coloration between maize kernels discolored and grain moisture percent. Microbial analysis showed associated fungi were Penicillium spp. (40.2%), Aspergillus spp. (37.4%), Fusariumspp. (12.6%), Rhizopus spp. (4.5%), Mucor spp. (3.8%) and Alternaria spp. (1.4%). F. verticillioides was the most frequency of Fusarium spp. Rates 83.8, 78.9 and 82.0% respectively in Deirezzor, Raqqa and Hasaka.Toxins (FUM) in Deirezzor was between 0.6 -5.3 mg / kg, and between 0.9 - 6.7 mg / kg in Raqqa, and from 0.2 to - 2.3 mg / kg in Hasaka, while Toxins (ZEA) were between 0.2-2.1, -0.5 7.6 and 0.03-0.8 mg / kg respectively in the three locations.Chromatographic analysis showed that the isolation of 42 out of 60 isolates of F. verticillioides was producing Toxins (FUM), were more isolates producing isolates Raqqa by 80%, in Deirezzor 70% and 60%. In Hasaka.

Field survey was conducted to identify plant nematode genera associated with maize crop during the period August-October 2003. The study was carried out at two locations: Kharabo station (Damascus countryside) and Al-Mraieh station (Deir Al-zowr) in Syria. 36 complex samples were collected from roots and rhizosphere soil; nematodes were extracted by two methods Sieving and Baermann funnel, examined under microscope for identifi cation. Population density and absulute frequency for each genera were calculated. Results of field survey showed the presence of 14 genera of plant parasitic, 4 fungivorous, and 12 omnivorous nematodes in maize roots and rhizosphere soil .
A survey was conducted to determine the frequency and mean densities of plant-parasitic nematodes associated with cotton crop (Gossypium hirsutum L.) after the harvesting season 2008 in Syria. Results showed that twelve genera of plant-parasitic n ematodes were found associated with cotton crop roots. The distribution of nematode genera varied between the Syrian governorates, Pratylenchus spp., Meloidogyne spp. and Rotylenchulus infect most cotton fields in all syrian governorates. The distribution was relatively uniform between the governorates. They occurred in 80.7%, 46.6% and 32.95%, respectively, of tested fields with an average density of 137.2, 59.6 and 574.3 juveniles/100 cm3 soil, respectively. meanwhile, the genus Tylenchorhynchus was found in central region only. Rotylenchulus was more prevalent in the heavier soils, but Meloidogyne. was not influenced by soil type. The other nematode genera detected in this survey were less frequent, their frequency of occurrence were for Hoplolaimus (19.3%), Scutellonema (31.8%), Tylenchorhynchus (31.8%), Helicotylenchus (30.7%), Rotylenchus (36.4%), Tylenchus (18.2%), Xiphinema (3.4%).
The aim of this experiment to study some of the blood parameters associated with hepatic coccidiosis induced by Eimeria stiedae in rabbits, and compare it with the blood changes when infected rabbits treating with the toltrazuril compound. 21 rab bit-old (4-8 weeks) were Used for this experiment of both sexes and were divided into three groups (seven rabbits in each group): Group of natural witness, and a Group of patient witness, where the infection caused by challenge dose of about forty thousand mature oocyst for each rabbit by mouth, and a treatment group that has been given the same previous challenge dose.
the best utilization of raw material for manufacturing the optimum quality of yarn has become inevitable for the spinning mills to face the global competition. mechanical properties of yarn are of the most important properties from quality point of view and largely depend upon the fiber length and micronair value ; which are considered the foremost quality parameters for the selection of raw material . it is the purpose of this study to investigate the effect of cottons differing fiber length and micronair value on mechanical propeties of yarn so as to contribute in determining the optimum using of the raw material .
This study was conducted at the Faculty of Agriculture, Damascus University, during two seasons (2002-2003) to assess the effect of irrigation methods (drip, sprinkler, furrow) of maize (Gota 82). The results showed significant differences between irrigation methods in grain and green weight production (average of two seasons, for grain: 6.48 t/ha,6.065 t/ha, and 7.905 t/ha for drip, sprinkler and furrow irrigation respectively, and for green weight 24.4t/ha, 22.04t/ha, and 25.75t/ha for drip, sprinkler and furrow irrigation respectively).Concerning total water requirement, drip irrigation method was the lowest one (average of two seasons, 4392.87m3/ha) followed by sprinkler irrigation (5565m3/ha) compared with furrow irrigation (9011.92m3/ha).
