The Effects of Organic Manure and Biofertilizer Application on Some Essential Oil Constituents of Coriander (Coriandrum Sativum L.)

In order to study the effects of organic manure and biofertilizer application on some essential oil constituents of coriander (Coriandrum sativum L.), an experiment was conducted as factorial experiment in the base of randomized complete blocks design with eight t treatments and three replications at research field of agriculture company of Ran in Firouzkuh of iran in 2012. The factors were organic manure contain vermicompost in four levels (0, 3, 6 and 9 ton/ha) and biofertilizer, mixture of Azotobacter chroococcum and Azospirillum lipoferum in two levels (non-inoculated and inoculated seeds). Results showed that vermicompost had significant effects on studied traits, as the highest gamma terpinene percent, camphor percent and geranyl acetate percent in essential oil were obtained after applying 6 ton/ha vermicompost. The minimum geraniol percent and maximum linalool oxide percent in essential oil were obtained after applying 3 ton/ha vermicompost. Biofertilizer, also showed significant effects on linalool oxide percent, camphor percent and geraniol percent in essential oil. The maximum linalool oxide percent, camphor percent and geraniol percent in essential oil were obtained by using the biofertilizer (inoculated seeds).
