The presented study was conducted in 2009 and 2010. Its aim was to evaluate the competitiveness against weeds of two winter wheat varieties, Ludwig and Nutka with different morphology. The study was based on a strict field experiment conducted at Experimental Institute of BASF Ltd in Pągów. The experiments were set up in strip plot design with 4 replications, localised on very good wheat complex soil. Both wheat varieties were sown at two dates: optimal time and with one month delay. Weed infestation was evaluated three times during vegetation – in autumn, before the start of resting phase, in spring during the phase of shooting, and after wheat flowering. The number and weed species composition in all tested experimental combinations was evaluated, as well as fresh weed weight determined from 1 m2. The results of experiments showed that the species composition of weeds was similar in each tested object, whereas their number and the fresh weight was strongly differentiated depending on the variety and sowing time of winter wheat. It was also shown that in case of both wheat varieties the weed competition higher influenced impact the grain yield than delayed sowing time. The yield structure analysis proved that tested wheat varieties, regardless of the sowing time, did not differ in the number of grains per an ear, but there were significant differences in 1 000 grain weight and crop stand.
