The aim of the conducted study was to assess the effect of two types of stubble catch crops (a mixture of legumes and white mustard) as well as varied nitrogen fertilization on weed infestation of a spring wheat stand depending on the adopted tillage system. Weed infestation assessed at the tillering phase of spring wheat showed the lowest number of weeds in direct sowing after the mixed legume catch crop. The next assessment of weed infestation performed at the flowering phase of spring wheat showed that the lowest number of weeds was found in direct sowing immediately after the catch crop of a mixture of legumes and white mustard for the complete nitrogen fertilization rate. The lowest weed dry weight was recorded in conventional tillage after a mixture of legumes for the complete nitrogen fertilization rate and after white mustard for a reduced nitrogen fertilization rate.
