Résumé anglais
The study was carried out for determination of changes in weed infestation of winter wheat cultivars under varying organic
and conventional crop production system. Research was realized in 2006-2009 in the Institute of Plant Protection in the
Experimental Station. The weed communities were compared using Shannon’s diversity index and Simpson dominance index.
The number and mass of weeds differed in the years as a result of different weather conditions and effectiveness of
weed control in production system. The results of performed studies revealed that at the time of conversion of conventional
production system to organic one the value of weed species biodiversity index was higher as compared to conventional cultivation
of winter wheat. Considering the period of conversion of conventional production system to organic it was found
that most common weeds were dicotyledonous with a dominance of Matricaria maritima. In case of conventional cultivation,
the value of species domination index was the highest for Apera spica-venti and Viola ssp. Increasing of sowing rate
the conversion to organic system haven’t influence on biodiversity index and the study showed that conventional crop production
decreases biodiversity.
