The research was conducted during the agricultural seasons 2016,2017 m in the Syrian coast in Tartous governorate, the village of Beit Sheikh Yunus. To study the effect of organic and chemical fertilization on some productive traits (number of flow er/plant, fruit weight /plant, weight of 1000 fruit gr, fruit yield Kg/h, harvest index%) of Coriander plant.
A population of soft wheat which lives naturally on the edges of saline Ain Malilah’s Sebkha, located to the southeast of Qasantina from the east of Algeria, and four varieties i.e. HD1220, ARZ, AS and ANF, to evaluate their performance under seve ral abiotic stresses conditions, and to study their response to fertilization, based on some phenological, morphological, chemical characteristics such as: Life cycle (from cultivation until the appearance of 1/4 spikes), germination potentiality, tellering, leaf area, total chlorophyll content, relative water content, carbohydrates content.
This search was carried out in the farm of faculty of Agriculture- Damascus during 2012-2013 to determine the adaption of five Safflower genotypes) Farming conditions in the lug intensive in the province of Damascus under the effect of different nitrogen fertilizers and witness without fertilization N3 . And how they affected safflower accessions morphological traits and productivity.
The experimental was carried out to estimation the influence of competitive irrigation, organic, and chemical fertilization treatments as well as the interaction of them on coriander plant (Coriandrum sativum L.) by FRCBD in three replications.
Experiments were conducted on field (2014) for knowing the effect of nitrogenous fertilizers (Ammonium Nitrate, Urea, Ammonium Sulfate) in increased concentrations with two ways of fertilization (Scattered, local) in growth of the young Beet plan ts class Dita (dry weight, density rooty, content of soil and plant from nitrogen) under condition of soil and climate in Deir Ezoor.
The present investigation was undertaken to estimate phenotypic correlation and path coefficient analysis for grain yield and its components in maize. Four local genotypes of yellow maize were evaluated in 2008 and 2009 growing seasons at two loca tions i.e. Damascus and Dir Al-Zor under three nitrogen fertilization levels (130, 195 and 260 of N. ha-1), The nitrogen fertilizer was applied at two splits. Split split plot design was used with 4 replications. Results of phenotypic correlation values showed that grain yield at Damascus location was positively and significantly associated with ear height (r= 0.204**), ear length (r= 0.205**) and number of rows per ear (r= 0.228**). On the other hand, grain yield at Dir Al-Zor location was positively and significantly associated with all studied traits at combined data whereas, it was positively and significantly associated with ear length at three levels and combined data (0.305*, 0.410**, 0.347** and 0.375**, respectively). The data of path coefficient analysis showed that ear length, ear height and number of rows per ear had positive direct effects on grain yield variation and thus grain yield improvement can be achieved through selection for ear length and ear height at Damascus location (11.06%). On the other side, data showed that each of ear height, number of kernels per row and 100-kernel weight had positive direct effects on grain yield variation (32.98%) and thus, 100-kernel weight can be considered as selection criteria may lead to the improvement of grain yield in yellow maize at Dir Al-Zor location.

the experiment was conducted under Syrian coastal conditions to investigate (Vicia fabaL.), the effect of boron and zinc foliar fertilization on faba bean,either individually or in combination, by increased rates (0, 0.25, 0.50, 0.75, and 1 kg boro n / has boric acid, and zinc at a rate of 0, 0.375, 0.750, 1.125, and 1.5 kg / ha as zinc sulfate). where fababeans were plantedin plastic pots(15L) in )2013/11/10(and )2014/11/10(.The soil in pots has high content of calcium carbonate, low boron and zinc content, with pH slightly basic (representative of the region's soils). Half boron and zinc fertilizer rates were sprayed after 33 days of germination and the other half ,after 65 days of germination. The results showed significant responses in all studied parameters (number of branches,number of pods / plant, weight of 100 seeds, and seed yield (Kg. / ha) on faba bean plant, as a result of foliar fertilization by boron and zinc. Fababeans response to boron is higher than to zinc fertilization in all studied indicators. However,the treatmentB75Zn75(0.75 kg boric acid and 1.125kg of zinc sulfate) is the best, as compared to others. Also, the driedseeds yield was increased by about 17.66%.
This research carried out in Al- Bassa village at Lattakia province during 2013-2014, to determine the effects of increasing rates of boron and zinc fertilization by foliar spraying, on root nodulation and seed yield of broad beans (Viciafaba L.). Se eds were planted in plastic pots (15 kg capacity), filled with sandy-silty soil, characterized by its poor content of boron, and represents most of lands in the region. Boron and zinc were sprayed by five increasing concentrations (Bo, B25, B50, B75 and B100) and (Zno, Zn25, Zn50, Zn75, Zn10)on broad bean plants at 33 and 65 days post-emergent. Results showed that treatments high significance than control, in termsof root length witch the best treatment was B100Zn100with 31c.m, and 2.85 g for B75Zn75 as a wight of length, on the other hand the best treatment for number of nodules was B75Zn75, 179.03 c.m, B100Zn100 was the best for height of the plant with 100.20, for protein B100Zn100 the best with 37.4%, However, boron and zinc fertilization treatment B75Zn75 is the best, economically.
This research was conducted to apply the technique of Artificial Insemination in poultry for the first time in the Syrian Arab Republic , and study the differences between the impact of the use of fresh or stored semen on the fertilization rate in hatching eggs . Results showed that the response to massage was different between cocks, It was greater in the cock A and cock B while the cock C was the least response to massage. The greater volume of ejaculate was obtained from the cock A( 0.072) ml ,and the least volume of ejaculate was obtained from the cock B (0.05) ml . The volume of ejaculate obtained from the three cocks was ranged between (0.049 -0.072) ml. The value of X in the count ranged between (230 - 237) sperm, semen concentration ranged between (4.6 - 4.7) billion sperm / ml. It also found that Insemination with a fresh semen injection yielded fertilization rate (91%), While insemination with semen injection cooling at the heat +4 ̊ C for 48 hours yielded fertilization rate (67%) .
