The present study investigated the effects of nitrogen fertilization on the yield and quality characteristics of Anise (Pimpinella anisum L.). The study was conducted in the ecological conditions of Kahramanmaras from 2019 to 2021. Two different anise populations Izmir (P1) and Konya (P2) and six different nitrogen fertilizer doses (0, 30, 60, 90, 120, 150 kg ha-1) were used in the study. The experiment was set up in triplicate using a split-plot design, with the populations on the main plots and the fertilizer doses on the subplots. Considering the herbal properties of anise grown in different nitrogen dose applications; plant height was 41.71- 42.75 cm, the total number of branches (10.62-12.50 plants-1), fruit branches (4.78-5.29 plants-1) and umbrellas (8.12-9.64 plants-1) were recorded. Considering the yield and quality characteristics; seed yield the range was 350.10- 400.02 kg ha-1, 1000-seed weight 2.78-3.49 g, protein rate 15.3-17.77%, fixed oil rate 15.15-16.34% fixed oil yield 50.51-60.48 kg ha-1, essential oil rate 1.66-2.26%, and essential oil yield 5.80-8.90 L ha-1. The Konya population had higher values in terms of seed yield and quality characteristics. With the exception of plant height, which revealed the total number of branches, fruit branches, umbels, seed yield, thousand seed weight, protein ratio, fixed oil ratio, fixed oil yield, essential oil ratio, and essential oil yield, all of the studied characteristics generally showed improvement with an increase in nitrogen doses. However, a nitrogen treatment of 120 kg ha-1 produced the maximum seed production.
