Abstract: A field experiment was carried out during winter seasons 2021-2022 and 2022-2023 on 5/11/2020 in Experimental field belonging to the Department of Field Crops at College of Agriculture at Tikrit University. It included three concentrations of arginine (0, 50, and 100) mg. liter and two spraying stages, branching and flowering, and six varieties of dill (Lot, Shynshal, Super Dukak, Backsha, Gribivisky, and Viola- Balady). Experiment was applied according to a Randomized Complete Block Design and in a split-plot arrangement twice. Results showed following Super Dukak variety excelled in traits of number of inflorescences per plant (24,389 inflorescences per plant) and number of seeds per plant (744.43 seeds). Plant-1 and seed yield (483.07) kg ha-1. Concentration exceeds 100 mg. Liters: Number of inflorescences per plant is (25,833) inflorescences per plant and number of seeds per plant is (716.3) seeds. Plant and seed yield (445.73) kg ha-1 (carvone 61.93) ppm and lemonene (20.16) ppm. Spraying stage during the flowering period was superior in number of inflorescences per plant ((23,389 inflorescences per plant) and seed yield (404.83) kg ha-1. The spraying stage during the branching period was superior in increasing compounds of carvone (60,774) ppm and lemonene (19,438) ppm
