The experiment was performed at Agricultural Research Center in Jousiyet Al-Kharab in Al-Qsair district, Homs governorate during the 2010-2011 season to investigate the effect of planting depth and organic acids on saffron growth and productivity. Four treatments including amino acids, amino Humic, mixture of them in addition to the control were applied. Each treatment was comprised of three planting depths (10, 15 and 20 cm). Results showed that by increasing planting depth up to 20 cm a significant reduction had resulted in the percentage of rooted plants and number of shoots while there were no significant differences between the two depths 10 vs. 15 cm. The number of leaves and their length were not affected significantly with the increasing of planting depths. The number of flower, wet and dry weights of the stigmas were increased significantly with the increase of planting depth from 10 to 15 cm. The application of the humic acids had significant superiority overall the other applications in rooted plant percentage, number of shoots, number of flowers and the dry and wet weights of the stigmas, while the application of the mixture came in the second rank in number of flowers and the dry and wet weights of the stigmas. However, no significant differences were occurred between the control and application of amino acids. The highest percentage of rooted plants was observed in applying humic acids in all depths and the percentage of rooted plants reached 100%. The highest number of flowers, highest stigmas wet and dry weights were observed with the interaction between applying humic acids at 15 cm depth. The highest number of shoots and number of leaves appeared with the interaction between 20 cm depth and humic acids treatment, the longist leaves were appeared with the interaction between amino acids and 15 cm depth.

The experiment was carried out at the end of April during 2013 In Abi- Jarash farm, Faculty of Agriculture, Damascus University in order to determine the influence of organic fertilization on the growth and yield of Snap bean. The snap bean ”Tema” Phaseolus Varity, and organic fertilizer” Humax” with two methods (root application and foliar spry) and two concentrations (2 and 4 g/L) were used. The organic fertilizer was used after two weeks of germination and then two weeks between treatment and another and the experiment was laid according to simple randomized block design. Results showed that organic fertilizer caused an increase of plants growth and yield, and the foliar spray method showed significant superiority (p<0.05) to some of the studied parameter such as plant dry weight (6.89 g), leaf area (4595.44 cm2), leaf area index (2.55), number of clusters (15.3 cluster/ plant), number of pods (29.6 pod/plant), plant yield (156.9 g/plant), compared to the root applied method. Results also showed no significant effect for the fertilizer concentration.
The research was conducted in village Habbet in Hafa (Lattakia region) 300 meters above sea level during the period of 2016-2017 the plant material of the research is red cabbage Ruby King F1 hybrid in order to study the effect of planting date on growth and productivity of red cabbage. The study consisted of five different planting dates during the med of May, June, July, August and ,September months The completely randomized block design was used with four replications and twenty plants in replication . The study contains indicators: )leaf surface area, shape, volume, solidity and weight of cabbage heads, inner stem length, total and marketable yield, percentage of marketable yield and content of vitamin C) The results showed that planting treatment during August and September gave the superior results with significant difference in vegetative and productive indicators: leaf surface area, solidity and weight of cabbage heads, total yield )3394.8، 3654( kg/d respectively, marketable yield and percentage of marketable yield. While The planting during May, June, July was superior on content of vitamin C which was respectively (99.58, 98.68, 97.82 ( ml/100g with significant difference.
We evaluated some of the qualities of productivity for lentil variety ( Lens esculanta ) Idlib2 in the province of Hama, which lies within the third zone in the two seasons 2013- 2014. manner random sectors dissident once and three replications fo r each worker where she planting dates widget Home and operated plant density widget dissident once in order to determine the date and density suitable to reach the best production of lentils in a peaceful area. Agriculture led on the first date (December 15) and in the plant a minimum density (200 seeds / m2) increased to varying significantly different in the length of the century / mm and the total number of horns on a per plant and the number of seeds per plant and seed weight on a per g / plant and seed weight per hectare And it gave the plant Top-density (300 seeds / m 2) a significant increase in the weight of centuries per g / plant and the number of pods on the plant and the weight of Aalakec per hectare and biological weight per hectare.
The aim of this research is to determine the role of mineral (NPK) and organic fertilization (Chicken manure, Cow manure and Chicken with Cow manure) on vegetative growth and flowering of Zinnia (Zinnia elegans). This research also examines the possi bility of relying on this organic manure to present nutrients for the plant in order to reduce mineral fertilization. The results show that the use of NPK (30, 20, 20 g/m2) or Chicken manure (2Kg/m2) has a positive impact on vegetative growth (plant height and average number of branches andleaves on the plant). They also show a positive effect on the flower developmentand flowering (early flowering, number of flowers and flower volume). These positive effects are reflected on the proportion of dry matter both in the vegetative and flowering part. The results indicate that plants fertilized with NPK or Chicken manure realize higher economic profit than the control and those fertilized with Cow manure.
A field experiment was conducted on sandy loam soil under the irrigation conditions in Deir- ezzor during the years of ١٩٩٨ and ١٩٩٩ to study effect of planting time and seed rate on growth and productivity of tow varieties of rape crop Brasica napous var. oleifera (Bromin & VEM).
