摘要：

Site-specific weed management reduces the amount of herbicides used and is therefore beneficial for economic and ecological reasons. Precise use of technology for site-specific weed management requires the development of decision support systems for weed control. Heterogeneity of studied fields was assessed and yield variability was determined. Field experiments were conducted in winter barley and maize in 2007. Maps of weed distribution, application maps, a soil- and yield maps were created in each of the fields. Statistical analysis of the data was done with a linear mixed model with anisotropic spatial correlation structure. This allowed quantifying the effect of weed competition, soil variability and herbicide on the grain yield for the two fields. Economic weed thresholds were calculated by using current prices for herbicides and grain. A decision algorithm for site-specific weed control was developed.
