Other claims from this paper (11)
- Intervention effect N + S fertilization increased seed yield, oil content and seed S uptake relative to N alone in all cases.
- Intervention effect N + S fertilization increased seed plus straw yield and seed plus straw S uptake relative to N alone in most cases.
- Intervention effect Application of N alone tended to reduce seed yield, oil content and seed S uptake of canola.
- Intervention effect Fertilizer S alone tended to increase seed yield, oil content and seed S uptake of canola.
- Intervention effect Fertilizer S alone had no effect on seed protein content of canola.
- Intervention effect Increasing the S rate from 15 to 30 kg S ha -1 generally increased canola seed yield and seed plus straw S uptake.
- Intervention effect Increasing the S rate from 15 to 30 kg S ha -1 had no consistent effect on canola oil and protein contents or S index.
- Intervention effect Topdressing S at bolting and flowering tended to give less canola seed yield than foliar-applied S in few cases.
- Intervention effect Method of S application had no consistent effect on other canola parameters.
- Intervention effect There were no noticeable differences in canola results among S treatments applied at seeding.
- Intervention effect Sulphate-S application is suggested to restore canola seed yield substantially at bolting and moderately at early flowering.
