Previous efforts to model crop yield loss from mul- tiple weed species constructed competitive indices based on yield loss from individual weed species. Our model uses a multispecies modification of Cousens' rectangular hyper- bolic yield function to estimate a nonlinear competitive index for weed-crop interference. Results from 13 Minnesota and Wisconsin data sets provide measures of the relative competi- tiveness of mixed green and yellow foxtails, common lamb- squarters, redroot pigweed… CONTINUE READING
