Competitive relationships between sugar beet and weeds in dependence on time of weed control

Popis výsledku v původním jazyce

Small plot trials were carried out in years 2001 - 2003 in sugar beet. On treatment without weed control, dry weight of sugar beet top and LAI of sugar beet were very low (approx. 50 g.m-2, resp. 0.5 m2.m-2). Yield loss of sugar beet was 80 ? 93 %. Dominant weeds were Chenopodium album, Fumaria officinalis and Galium aparine. On treatments, where weeds were removed (by hand) until 4 leaf stage of sugar beet, dry weight of sugar beet top and LAI of sugar beet at first increased normally, but were markedly decreased from the half of vegetation period. Yield loss of sugar beet was 54 ? 28 %. Dominant weed on this treatment was Amaranthus retroflexus. The development of sugar beet top dry weight and LAI of sugar beet was practically identical on treatments, where weeds were removed until 8 - 10 leaf stage of the crop compared to treatment, where weeds were removed during the whole vegetation period (500 - 900 g.m-2, resp. 4 ? 7 m2.m-2). No yield loss of sugar beet was recorded. Dry weight
