Abstract

Weed infestation of durum wheat was determined in the systems of conventional tillage
(CT), reduced tillage (RT) and herbicide tillage (HT). Cultivations measures performed after the
harvest of the previous crop included shallow ploughing (at a depth of 10-12 cm) and pre-winter
ploughing (25-30 cm) in the CT system; only field cultivation (10-15 cm) in the RT system; and
spraying with glyphosate (Roundup 360 SL) in the HT system. In the springtime, a tillage set
consisting of a cultivator, a string roller and a harrow (10-12 cm) was applied on all plots. It was
demonstrated that wheat cultivation in the RT and HT systems was increasing the number and
weight of weeds, compared to the CT system. The highest number of weeds occurred at the
middle level of wheat crop, whereas the highest air-dry weight was produced by the weeds at
the upper and middle crop levels. In the HT system, weed community was constituted
exclusively by short-term species, whereas in CT and RT systems – by short-term and perennial
species.
