Abstract

Objectives: This research investigates the effect of different methods of application of micronutrients aminochelate on increasing the growth and essential oil of shoot and seeds of dill as a medicinal plant.
Materials and methods: Experiment was conducted during 2018-2019 in the research farm of Department of Horticultural Sciences, Shahid Chamran University of Ahvaz, in form of a randomized complete block design with 4 treatments and 4 replications. The treatments included micronutrient aminochelate in three forms: foliar spray, irrigation and combination of foliar spray and irrigation, and the control.
Findings: Results showed application of aminochelate had effects on vegetative characteristics such as plant height, fresh and dry weight, number of umbels, seed weight and yield, essential oil of shoots and seeds. Growth indicators such as plant height, wet and dry weight, as well as grain yield, were significantly increased in aminochelate treatments compared to control, and among the treatments, the combined application of aminochelate had the most effect on dry weight 29.02 gram, 1000 seed weight 2.30 gram and seed yield 718.20 gram per meter square. Analysis of essential oil showed that the plants treated with combined application of aminochelate had the highest amount in shoot essential oil yield 3.64 and seed essential oil 4.64 gram per meter square.
Conclusion: The combined application of aminochelate fertilizer in the form of foliar spray and irrigation has a positive effect to increase the yield of seeds and essential oil as well as to improve the growth characteristics of dill as a medicinal plant.
