Efficient nitrogen fertilizer use is a vital component to profitable crop production and sustainable agriculture in Western Canada. Oats have a reputation for being less responsive to N additions due to lodging. This may cause producers to reduce inputs resulting in oat yields below their genetic potential. A registered semi dwarf oat cultivar could lead to significant improvements in grain yield and quality at higher N levels. Comparisons of the semi dwarf versus taller cultivars are necessary to evaluate their potential for western Canadian production systems. Experiments were conducted in 1998/99 to define the characteristics of high yielding, high quality oat cultivars, both tall and semi dwarf, and their response to nitrogen fertility. Cultivars included AC Assiniboia, AC Medallion, Triple Crown, CDC Boyer, and OT288, an unreleased semi dwarf line. Results from the 1998 sites found N fertilizer to increase yield at two of four sites. OT 288 yielded consistently higher than the taller cultivars at all locations. Cultivar significantly affected grain quality parameters. An analysis of grain yield and oat milling quality for both site years will be discussed.
