As parsley seed vigour is known to be low, a 3-year field study was conducted to examine the effectiveness of seed priming and pelleting. Hardening and solid matrix priming (SMP) were applied to two varieties (Cukrowa and Berlińska). Both methods of seed pre-sowing treatment increased the percentage, speed and synchrony of seedling emergence. Due to seed pre-treatment the original root yield of cv. Cukrowa increased by 6.45 to 7.09 t/ha and that of cv. Berlińska by 2.44 to 5.48 t/ha, depending on the priming technique. Pelleting of primed seeds negatively affected seed vigour as compared to the primed non-pelleted seeds.
