EFFECTS OF ORGANIC FERTILIZERS ON ESSENTIAL OILS CONSTITUENTS AND SOME CHARACTERISTICS OF PURPLE BASIL
Abstract


Basil (Ocimum basilicum L.) is one of the most important medicinal plants as its essential oil used in different industries including pharmaceutical, cosmetic and food. Fertilizer management is utmost important factor in success of pharmaceutical crops cultivation. Application of organic manures is important in production of these plants with the aim of elimination or significant reduction of chemical inputs and increases of soil fertility and improvement of plant growth and quality. Therefore, an experiment conducted on basil in research field of Agriculture Faculty of Zanjan University. A complete randomized blocks design with ten treatments and three replications were used. Treatments were cattle manure, vermicompost and poultry manure in three levels (5, 10, and 15 ton/ha) and control. Different characteristics such as plant height, leaf area, number of lateral branches, leaf dry weight, total fresh weight, essential oil content and essential oil percentage evaluated. According to the results, all studied characteristics affected by different types of organic manure and the highest records were obtained at 15 ton/ha vermicompost. Percentage of essential oil was also significantly affected by organic manure treatments and the most percentage of essential oil was respectively obtained in 15 ton/ha vermicompost (1.12%) and 10 ton/ha vermicompost (1.10%). In addition, analysis by GC and GC/MS showed that the main components of the essential oil (such as methyl chavicol and linalool) affected by organic amendments and using the three types of organic fertilizers increased the linalool content of essential oils. The maximum amount of linalool obtained from treatments of 15 ton/ha cattle manure and vermicompost fertilizers. The lowest methyl chavicol content of essential oils obtained from 15 t/ ha vermicompost treatment.
