Sugar beet belongs to the most productive crop. It produces high yields, which is also very energy rich (sugar). Therefore this plant species is often calls "queen of the field" as it has high requirements for environment condition. In these studies, we research the influence of the time from planting to emergence from different planting dates on percentage of field emergence and roots yield per plant at harvest time. There were four next planting date: 1) March 20-25, 2) March 26-31, 3) April 10-15 and 4) April 20-25. Number of days from planting to emergence, on average was 14, 15, 14 and 8 respectively for first, second, third and fourth planting dates. The average root weight at harvest ranged from 795 g (fourth planting date) to 1106 g (first planting date). In the same planting date root yield also varied. In the first planting date this variation were from 800 g to 1232 g per plant (the last and the first day of the emergence) and in the least planting date from 510 g to 778 g per plant.
