Indirect weed control in wheat by variety selection and high crop density

摘要

The aim of this study was to identify wheat cultivars (sown at different seed rates) which can compete with a mixture of grass and broad-leaved weeds and to determine significant characteristics of the wheat plant that contribute to competitiveness with weeds. Results showed that the lower seed rates of both cultivars had the highest emerged grass weed populations whilst the number of broad-leaved seedlings were about similar at all seed rates. Biomass production of the weed species is also discussed
