Simulation of Above-Ground Suppression of Competing Species and Competition Tolerance in Winter Wheat Varieties Organic Eprints
Olesen, Jørgen E.; Hansen, Preben Klarskov; Berntsen, Jørgen; Christensen, Svend.
Cereal crop species and varieties differ in competitive ability against weeds mainly as influenced by differences in canopy architecture. The FASSET crop model was used to separate the effects of a number of crop traits on the suppressive ability of winter wheat varieties and the ability to tolerate weeds. The model simulated the competition between different varieties of winter wheat and a sown grass mixture for light, water and nitrogen. Crop physiological parameters of eight varieties and one variety mixture were estimated from measurements in a 3-year field experiment. The parameters estimated were thermal time from emergence to flag leaf appearance, thermal time from flag leaf appearance to anthesis, thermal time from anthesis to yellow ripeness,...
