Madsen, Karen E. Sowers, Haiying Tao March 14, 2020 Photo courtesy of Haiying Tao. Winter canola (WC) offers not only marketable products but also excellent rotational benefits through disease, weed, and pest control in the dryland cropping systems of the inland Pacific Northwest (iPNW). However, little regional fertility research has been conducted on WC. The objectives of this study were to (i) determine the influence of soil N supply and fertilizer N rate and timing effects on WC yield in four iPNW agroecological classes and (ii) evaluate how N availability and fertilizer N application timing affect WC seed quality.Abbreviations:ACannual crop;AECsagroecological classes;AFTannual crop–fallow transition;GFgrain–fallow;iPNWinland Pacific Northwest;IRirrigated;SCspring canola;WCwinter canola.
