Other claims from this paper (12)
- Observation Winter survival remained high after date 4 planting in two Ottawa years.
- Intervention effect Early planting increased wheat grain yield.
- Observation Maximum yields at Douglas came from planting dates 1 and 2.
- Observation Maximum yields at Ottawa and Kemptville came from planting dates 1 to 3.
- Observation Date 2 planting had a significant advantage at Kemptville.
- Intervention effect Late planting reduced kernel weight and test weight.
- Association Grain yield and winter survival were highly correlated in seven of nine location-years.
- Intervention effect At Ottawa, 160 kg ha −1 seeding significantly increased yield relative to 130 kg ha −1.
- Association Higher seeding rates gave greater yield increases at later planting dates.
- Observation Cultivar effects on grain yield were frequently significant.
- Observation Cultivar effects on winter survival were less often significant.
- Observation Houser had the highest yield in five of nine location-years.
