Ecological seed is very necessary, but its quality is often much lower than of conventional seeds. The aim of the study was to compare the sowing value of organic seeds of different vegetable species with their conventional equivalents. The research was carried out on the seeds of lettuce, cucumber, spinach and beet from PlantiCo (Zielonki, Poland). The seeds were sown under laboratory conditions in the containers lined with blotting paper and on Petri dishes to observe the course of germination and in soil to observe the emergence process. The weight of one thousand seeds of each species and type was estimated, and the price-seed ratio in the package was established. In general, conventional seeds were characterized by a higher sowing value and a mass of thousand seeds as compared to their organic equivalents. The differences in quality depended on the species. The quality of organic lettuce seeds was the lowest. There was also a high percentage of damages seeds of organic cucumber (10%).
