Other claims from this paper (19)
- Intervention effect In N.W. Saskatchewan, nitrogen increased rapeseed yield by 1.00 t ha −1.
- Intervention effect In N.W. Saskatchewan, sulphur increased rapeseed yield by 1.06 t ha −1.
- Intervention effect In N.E. Saskatchewan on Sylvania f1, a combination of S and B increased rapeseed yield by 0.38 t ha −1.
- Intervention effect In N.E. Saskatchewan on Sylvania f1, nitrogen increased rapeseed yield by 0.78 t ha −1.
- Association Sylvania f1 soils were lower in soluble B than other experimental sites.
- Intervention effect At other sites in N.E. Saskatchewan, nitrogen but not sulphur increased rapeseed grain yield significantly.
- Intervention effect The cultivar Regent responded significantly to a combination of S and B.
- Intervention effect Both species of rapeseed responded to sulphur fertilizer.
- Intervention effect Sulphur fertilizer increased glucosinolate concentration in rapeseed meal at all sites.
- Intervention effect Sulphur increased oil concentration of rapeseed on all sites except one where frost damaged the crop.
- Intervention effect Sulphur increased grain protein on sites with a yield response to sulphur.
- Intervention effect Nitrogen combined with boron decreased rapeseed protein on all sites except Sylvania f1.
- Intervention effect Nitrogen combined with boron increased rapeseed oil percentage on all sites except Sylvania f1.
- Association The yield response of cultivar Regent to boron was not significantly related to soluble soil B.
- Association The combined yield response to sulphur and boron was significantly related to soluble soil S and B (R 2 = 0.60).
- Association Yield response of rapeseed to sulphur was significantly related to soluble soil S (R 2 = 0.35).
- Intervention effect Sulphur fertilizer solved the problem of poor seed set in rapeseed cultivars.
- Intervention effect Boron enhanced rapeseed yield.
- Mechanism Boron enhanced rapeseed yield by decreasing sterile florets and improving pod development.
