MORPHOLOGICAL DIFFERENCES BETWEEN SUGAR BEET AND WEED BEET (BETA VULGARIS L.) DEPENDING ON THE SOIL

An evaluation of selected morphological traits (plant height, leaf width and length) for the Sugar beet and weed beets cultivated in early BBCH phases (11-12, 14-15) in a pot trial on four different soils. The variability of monitored traits between sugar beet and weed beet depending on the soil qualities was not significant. The height of weed beet was significantly lower, in BBCH 11-12 (25 mm +/- 9.81), growing from the glomerules affected by the total herbicides, for this variant field germination was also found to be significantly the lowest. 5 weeks after their emergence weed beets started to create stems, which were also probably influenced by favourable temperature conditions. The plant height, leaf length and width for sugar beet were greater in comparison with weed beet, though statistically insignificant. A considerable of weed beet variability in the monitored traits is apparently genetically conditioned.
