Seed priming is a crucial technique in modern agriculture. This practice can significantly improve the germination rate of seeds, as well as their resistance to diseases and adverse environmental conditions. Several investigations have shown that priming contributes positively to the speed of emergence in various vegetable crops such as chard (Beta vulgaris Cycla Group), spinach (Spinacia oleracea) and carrot (Daucus carota), resulting in great economic help. To determine the effect of priming in terms of the variables speed and percentage of emergence in chard, spinach and carrot seeds, this investigation was carried out; two types of priming were used: halo priming, with the seeds submerged in 3% sodium chloride for twelve hours and hydropriming, with plain water for five hours. Then the seeds were sown in open field conditions. In order to determine the percentage of seed emergence at four, seven, fourteen, eighteen and twenty-eight days, the number of emerged plants was calculated from the first day of sowing. On the other hand, to evaluate the speed of emergence, the number of plants emerged per day is calculated. This is achieved by dividing the total number of plants emerged up to the count date by the number of days elapsed from sowing to the respective count. The results showed that the priming halo had a greater effect on the emergence of chard seeds, on the other hand, in the spinach crop the best effect was with the hydropriming treatment, however, in carrots no effect was observed with any of them. the two treatments. Statistically the results were not significant
