Abstract
Response functions relating crop yield in a weed-crop mixture to weed and crop densities are mainly empirical. Few functions such as the inverse yield law and some of its mathematical extensions are quasi-logical and possess biologically meaningful parameters, but none of these simple models has been interpreted in terms of one-sided and two-sided competition. The inverse yield law and some related equations can, however, be interpreted in this sense. To select the appropriate model among these mathematically interrelated equations, they were all fitted to data sets from four wheat-wild oat competition experiments, sown in an additive series design (...)
