Results showed that Imperial Star produced higher values of vegetative growth, yield productivity, and chemical contents, compared with Romanesco cultivar. GA3 foliar application treatment ranked the first to increase vegetative growth, yield productivity, and chemical contents, followed by melatonin treatment, compared with untreated control. It could be concluded that the use of GA3 and melatonin were favorable for the production of both artichoke cultivars: Imperial Star and Romanesco. The highest productivity was achieved by foliar application of GA3 to Imperial Star cultivar.
