Other claims from this paper (15)
- Intervention effect Sidebanded nitrogen at 40, 80 or 120 kg N ha-1 increased yield, nitrogen uptake and seed protein content.
- Intervention effect Seedrow nitrogen at 40 kg N ha-1 increased yield, nitrogen uptake and seed protein content.
- Intervention effect Those placements did not reduce emergence.
- Intervention effect Those placements reduced seed oil content.
- Intervention effect Seedrow placement at those rates did not affect seed protein or oil content.
- Observation Canola yield and nitrogen uptake responded up to 120 kg N ha-1 with sidebanding.
- Observation With seedrow placement, yield responded to 40 kg N ha-1.
- Observation With seedrow placement, nitrogen uptake responded to 80 kg N ha-1.
- Intervention effect Deep seeding reduced emergence, yield and nitrogen uptake in many cases.
- Intervention effect Deep seeding had no effect on seed protein content.
- Intervention effect Deep seeding reduced seed oil content in some treatments.
- Observation At low nitrogen rates, knives generally gave better emergence.
- Observation At higher seedrow nitrogen rates, shovels tended to be superior.
- Association The negative effect of seedrow placement grew with deeper seeding, higher nitrogen rate and narrower placement band.
- Recommendation Practices that maximize emergence and minimize fertilizer damage optimized seed yield response to nitrogen.
