Abstract

Crop-weed competition between maize (Zea mays, L.) and weed plants was investigated 4 and 7 weeks after seeding the crop plant in a 9.2 ha field by surveying weed populations in a site-specific manner. Surprisingly, evaluation of the data showed little or no crop-weed competition during the first 4 weeks of the crop plant's development. The apparent lack of crop-weed competition may be due to the extreme drought during this time (no precipitation in the study area after the middle of February until early June). Stronger weed competition was detected only after 7 weeks of plant growth. Our results indicate that the extent of maize-weed competition in the field is strongly dependent on the availability of water essential for crop and weed germination and emergence.
