Abstract: With red beetroot(Beta vulgaris L. var. rapacea Koch.)cultivar ‘BR07-5’ as the experimental material, effect of different sowing dates, different covering soil thickness after sowing, planting and sowing patterns and different harvest dates on growth and yield of red beetroot were studied in Tianjin area. The results showed that individual root weight and yield of red beetroot sowed in late summer and early autumn were significantly decreased as postponing sowing date, but fleshy root texture was firmer when red beetroot was sowed too early, so it was confirmed that the appropriate sowing date was August fifth. Seedling emergence time of treatment of covering soil 0.5 cm after sowing was significantly shorter than those of treatments of 1.5 cm and 2.5 cm and seedling emergence rate of treatment of covering soil 0.5 cm after sowing was significantly higher than those of other two treatments. The plant height of transplanting seedling treatment was significantly lower than that of direct sowing treatment, while leaf number and leaf weight were greater than that of direct sowing treatment, transverse diameter and vertical diameter of fleshy root, individual root weight and yield were all lower than that of direct sowing treatment. While thinning seedling we could remedy missing seedlings and ensure higher yield through transplanting seedling. Individual root weight, yield and texture of red beetroot harvested in November seventh were better.

Key words: red beetroot, sowing date, covering soil thickness, transplanting, harvest date
