Nutrient seed priming was tested to improve seed germination, growth and yield of dill ($Anethum$ $graveolens$ L.). The priming solution concentrations chosen for the tests were 0.5%, 1%, 1.5% and 2% Zn ($ZnSO_4{cdot}H_2O$) or Mn ($MnSO_4{cdot}3H_2O$), and 1.5% Zn+1% Mn. Priming at the concentrations of 1%; 1.5% Zn, 1% Mn, or 1.5% Zn+1% Mn increased the rate of germination of dill seeds compared to the control. The lowest seedling dry weight was recorded in 2% Mn. Similarly, the seedling vigour index in Mn-primed seeds was restricted, when Mn concentration increased more than 1%. The highest seed yield was recorded in 1.5% Zn + 1% Mn, 1.5% Zn, 1% and 1.5% Mn solutions, which produced nearly 20%, 18%, 14% and 13% greater yield than control, respectively, but yield reduction was found when the seeds were primed in higher concentrations. Seed essential oil among treatments ranged from 3.14% in 1.5% to 2.90% in 0.5% Mn solutions. In field experiment, the recorded data showed obvious positive response to seed priming with Zn and Mn regarding essential oil yield of dill. The primed seeds in 1.5% Zn + 1% Mn solution showed a further increase of crop yield over control.
