dc.description.abstractExperiments were set out as a rotational composite design with five rates of N, S, and B at 10 sites over a period of four years on Sylvania fine sandy loam, Waitville, and Melfort silty clay loam in northeastern Saskatchewan and Loon River loam in northwestern Saskatchewan. Experiments on Sylvania fine sandy loam over four years showed that N, and the S by B interaction increased 'Regent' canola yield significantly. Other sites in northeastern Saskatchewan showed yield increases from N fertilizer and sites from northwestern Saskatchewan showed significant yield increases from N and S fertilizer. On the Sylvania fine sandy loam site over a period of four years, the lowest yield was 1.04 t per ha (ha-1) with 0 kg N, 25 kg S, and 1.4 kg of Boron (B) ha-1. The highest yield of 1.82 kg ha-1 was obtained with 200 kg N, 25 kg S, and 1.4 kg B per ha-1. Sulphur increased glucosinolate concentration from 7.3 to 10.1 μmoles g-1. Nitrogen fertilizer decreased oil concentration (46.1 to 43.3 %) but S increased oil content (43.9 to 45.5 %). Conversely, N increased protein content from 48.4 to 51.6 %. Also, S increased protein content from 48.9 to 49.9 %. The above variables also, were affected similarly at other sites in northeastern and northwestern Saskatchewan.en_US
