The chemical composition of coriander (Coriandrum sativum L.) using GC/MS as influenced by different types of fertilizer nutrition

Abstract

A field experiment in Syria was carried out in Tartous Governorate - Baniyas region during the 2018 agricultural season to study the effect of three types of organic fertilizers (cow manure-compost-poultry) at a rate of 15 tons H-1 and chemical fertilizers on the proportions of the active ingredients of the essential oil of coriander plants. The experiment was carried out in a complete random sector method. The results showed the difference in the percentages of the active compounds according to the different fertilizer sources, as the chemical nutrition caused reduction in the value of linalool, the main compound in coriander oil, while it caused the formation of new compounds, including 1,2-Benzisothiazole and is characterized by a high inhibitory ability to grow fungi and this reflects the possibility of using this compound to save food and prevent microbial spoilage. Whereas, the results of organic fertilizers were significantly indifferences in
the proportions of linalool. The results of the interaction also showed that there were significant differences among values of studied chemical compounds in relation to fertilizer treatments among values of studied chemical compounds in relation to fertilizer treatments between the fertilizer treatments and the compounds studied. This can be explained by the fact that the chemical fertilizer demonstrated the highest value of carboxylic acids 57.59%, then compost fertilizer recorded the best value for hydrocarbons 41.83%, while poultry manure achieved the highest value for alcoholic compounds 38.97%.
