Abstract. The study was conducted in the fields of a farmer in Baghdad Province/ Abu Ghraib district during the 2019-2020 agricultural season to study the effect of two factors. The first factor was spraying salicylic acid on the plant with four concentrations (0,100,200,300) mg. L -1. The second factor was spraying amino acid Arginine on the plant with four concentrations (0,100,200,300) mg. L -1. Each level was sprayed before sunset until the plant leaves become completely wet. The spraying was done twice during the growing season. Results showed that the treatments of foliar spray with Salicylic Acid, the treatment with Arginine spray, and the interaction treatments were superior in terms of improving plant height, leaf area, and ratios of volatile oils ratio, phenols, nitrogen, and proteins
