In order to develop a better cultivation method for BARI Ajowan-1, it is very important to identify the seed rate first. Therefore, this experiment was conducted at Spices Research Sub-Centre, Faridpur during the rabi season in 2019-20 and 2020-21. Total of five seed rates (3.0, 3.5, 4.0, 4.5, and 5.0 kg/ha) were evaluated here with three replications, and a randomized complete block design was followed. From two years' results, the 2019-20 season showed better performances due to positive environmental conditions. Maximum traits, e.g. plant height, branch number, umbel number, yield, etc. showed significant responses by different seed rates. Among this seed rate, the seed yield obtained highest (987.48 kg/ha) at 4.5 kg/ha. Among all yield and yield contributing traits, branches per plant, 1000-seed weight, and umbel per plant were the important traits for variability creation and were mostly responsible for seed yield. From these findings, it is concluded that for better growth and yield 4.5 kg/ha seed rate is best for Ajowan cultivation.
