Response of Annual Canarygrass (Phalaris canariensis L.) to Nitrogen Fertilizer and Fungicide Applications

Annual canarygrass (Phalaris canariensis L.) is a specialty crop grown in Canada and the harvested grain primarily used to feed wild domesticated bird species. A field experiment was conducted at 5 locations both 2012 2013 study response of annual development yield combined effects fungicide (propiconazole + trifloxystrobin) nitrogen (N) fertilizer determine minimum number site-years required detect these effects. The experimental design split plot with application (none or fungicide) as main N rate sub (10, 20, 30, 50, 70, 90 kg ha-1). There linear increase 14.5% increased. increased 8.5% by increasing kernel density from 15,197 kernels m-2 16,288 m-2. no interaction between application. did not responsiveness fertilizer. lack an indicates that two practices can be managed independently producers. To optimize producers should apply 50 ha-1 especially regions where septoria leaf mottle prevalent. site years needed consistently impact on were 4 site-years, respectively.
