Iranian black zira is an aromatic and medicinal plant from Apeaceae family. In order to investigate the effect of fertilization and tuber age on plant height, greening percentage, flowering percentage, and yield components, an experiment was conducted in field conditions in the form of 9 main plots including NPK fertilizer at three levels (control ), fertilizer 1(2.5 grams per liter), fertilizer 2 (with a concentration of 2 times and 5 grams per liter) and tuber age at two levels of three and four years (medium and three-year-old tubers ) was carried out in, fertilizer with 2 times concentration) and tuber age at two levels (three and four years old) was carried out in 1402-1403 in Kalat region of Khorasan Razavi.The results showed that tuber weight has a direct and positive effect on the percentage of germination, flowering, plant growth and yield. The highest percentage of greening (100%) and flowering (100%) was observed in large tubers and the lowest percentage of greening (51%) and flowering (16.93) was observed in medium tubers and 0 fertilizer (no fertilization).application of 20-20-20 fertilizer (NPK) and use of tubers with more age (weight) improved the growth and yield of Iranian black zira.
