CHANGES IN WEED COMMUNITIES ON SELECTED AREAS WITH 30 YEARS´ INTERVAL

Popis výsledku v původním jazyce

In 2005 the evaluation of weed infestation in field crop stands was carried out in sugar-beet production area in the middle and northern Bohemia. There were analyzed the same locations as in 1975. By that way, it was possible to compare the weed composition on chosen areas after 30 years, exactly. To unify and unbiase the monitoring, the same research methods were used and the comparable crops were evaluated. By that way, it was acquired 7 relevés, mainly in cereals. The results proved important changesof weed communities. The average coverage of weeds declined rapidly in 85.59% (1975 ? 43.57%, 2005 ? 6.28%), whereas on many locations the decline was much higher. From the point of view of the species richness, in individual relevés there was found decline about 46.10% (1975 ? 32.86 taxa, 2005 ? 17.71 taxa). Changes were recorded in a particular species´ composition of agrophytocoenoses.
