Under good fertilizing and irrigating conditions, the highest root yield was 183 t/ha, the epigeal (stalks and leaves) yield was 220.5 t/ha, the economic yield was 403.5 t/ha. In beet root, the dry matter was 11.87%, the protein of the dry matter was 13.73%, the sugar content was from 6.5% to 6.7%.
