Effects of Zinc Application on Some Important Yield and Quality Characteristics of Coriander (Coriandrum sativum L.)

Abstract

In this study, the effects of zinc application on the yield and quality characteristics of coriander was investigated. The experiments were conducted in randomized blocks split plots experimental design with 4 replications. In the experiment, coriander cultivars (Arslan and Gürbüz) were placed in the main plots and zinc doses (Control, 200, 400, 800 g da-1) were placed in the subplots. In the study, cultivar x zinc interaction was significant in the number of umbel per plant and essential oil content; zinc treatments were found to be significant in the number of branches per plant, biological and fruit yield, essential and crude oil contents; cultivars were significant in thousand fruit weight and harvest index. In this study, essential oil content varied between 0.40-0.55% and crude oil content varied between 10.8-14.6%. In essential oil composition analysis, linalool was the main component, while in fatty acid composition analysis petroselinic acid was determined as the main component. At the end of the study, it was determined that 800 g da-1 zinc dose of Arslan cultivar was appropriate in terms of fruit yield. Also, the 200 g da-1 zinc dose of Gürbüz cultivar and the 800 g da-1 zinc dose of Arslan cultivar had the highest values in terms of linalool and petroselinic acid ratios respectively.
