In order to investigation of effect of iron and zinc sulfate on quantitative and qualitative yield of coriander, an experiment was conducted as randomized complete block design with three replications during 2015 on the Research Field of Payam Noor University of Marand. Treatments consisted of control, foliar application of iron (in stem elongation, flowering and stem elongation + flowering stages), foliar application of zinc (in stem elongation, flowering and stem elongation + flowering stages) and foliar application of iron and zinc (in stem elongation, flowering and stem elongation + flowering stages). Results showed that foliar application had significant effect on all studied traits except number of lateral branches. The application of iron and zinc improved plant traits in comparison to control. The highest values of plant height, Number of lateral branch per plant, total dry weight, 1000-seed weight, seed yield and essential oil yield were gained of foliar application of iron and zinc in both stem elongation and flowering stages. Foliar application of Fe +Zn in stem elongation and flowering stages more than twice increased grain yield compare to control treatment. The highest and the lowest essential oil yield (3.31 and 1.11 kg/ha) was gained in application of Fe + Zn (in stem elongation and flowering stages) and control treatments respectively. In general, results showed that simultaneous foliar application of iron and zinc in stem elongation and flowering stages can be improved quantitative and qualitative yield of coriander which could be used as a suitable management strategy.
