Verbatim
e0“grain of canola (oil-seed rape; Brassica napus L.) was measured in two field experiments”
e2“in south-western Australia, on soils deficient in P and N”
e1“Significant grain yield increases (responses) to applied P occurred in both experiments”

Other claims from this paper (8)
- Association The yield response to applied P increased as the rate of applied N increased.
- Association The P × N interaction was significant for canola grain production in all eight years and locations.
- Intervention effect Applied P had no effect on the oil and protein concentration of canola grain.
- Intervention effect Applied N decreased the oil concentration of canola grain.
- Intervention effect Applied N increased the protein concentration of canola grain.
- Observation Canola grain responses to applied N always occur in the region.
- Observation Canola grain responses to applied P are rare in the region.
- Recommendation Where soil P testing indicates likely P deficiency, both P and N fertiliser should be applied to canola.
