abstract:
Field experiment was conducted over the years 1998�2000 in the Experimental Farm Uhrusk, a part of the University of Agriculture in Lublin. The experiment was set up on podzolic soil formed from coarse sandy soil, that belong to a good rye complex. The studies included the infecation of crop canopy (spring triticale, oats and winter rye) cultivated in multispecies cereal monoculture against a different agrotechnical level. The greatest weed biodiversity within the cereals studied showed spring triticale and winter rye. From 20 to 26 weed species were recorded there and the species dominant in the mentioned cereals were mainly short-lived weeds. They made up 81.0% in spring triticale and 86.5% winter rye. The lowest weed biodiversity was demonstrated by oats whose canopies had from 15 to 23 weed species with short-lived species (85.4%) predominance either. A higher agrotechnical level caused impoverishment of the flora weeding of cereals and a decrease of the infestation indices, i.e., weed number and the biomass.
