Abstract

The experiments were conducted under sandy soil conditions to study the effects of foliar application of Fe, Zn and Mn on essential oil, growth and yield of onion plants (Allium cepa L.). Plants were sprayed with two concentrations of each of Fe, Zn and Mn (chelated form). Essential oil, growth characters and yield were measured in response to the applications of these micronutrients. The results revealed that essential oil, growth and yield of onion plants significantly increased by the application of Fe, Zn and Mn compared to control plants. The results showed that the high concentration of Fe and the low concentrations of both Zn and Mn had the best effects compared to the other concentrations. The effects of Fe, Zn and Mn on essential oil, growth and yield of onion plants are discussed.
