• This spring’s growing conditions are extremely stressful for canola seedlings and can severely affect germination and emergence. As a result, assume (best-case scenario) average emergence will occur. It is realistic to assume only 50% of the seeds planted will result in healthy seedlings. Recognizing that yield potential starts to drop when seeding is delayed after……

  • Snow, freezing temperatures on four to five nights and in some areas, heavy frosts (as low as minus 7°C), occurred across the Prairies last week. This may prompt canola growers to consider reseeding. However, resist the urge to reseed immediately, as recovery may turn out to be better than expected, especially if seed has not……

  • Soil Moisture Still Poor to Excess Unseasonably cool and dry conditions prevailed across the prairies last week.  Spotty rainshowers and a few snow flurries meant additional moisture was received but these events were quite localized. As a result, soil moisture conditions continue to range from poor to excess. In Manitoba, much of the Red River……

  • Seeding operations progressed late last week and over the weekend. Where conditions are wet, acres are being seeded on a field by field basis. Seeding in the wetter areas is probably five to 10% complete. In the drier areas, seeding of cereals and pulses is nearing completion and seeding of canola is becoming more general……

  • Some areas have had canola seeded for almost two weeks now. You may question the viability of the seed, especially under recent growing conditions. Even if surface emergence is not apparent, scrape back the soil and find the seeds. The condition of the seeds can help determine the state of germination/emergence. Hard seeds are probably……

  • Frost has been reported regularly and the forecast for the coming days remains cool with over-night frost in many areas. If canola has emerged, remember a proper assessment of frost damage can’t be made for several days, until it can be determined if new growth is appearing on damaged plants. One benefit of the growing……

  • Soil moisture conditions across western Canada range from poor to excess. In Manitoba, the Red River Valley still remains submerged under the swollen Red River although water levels have receded 2 ½ feet. The majority of agroManitoba has good to excessive moisture. In Saskatchewan, soil moisture conditions range from dry to excellent. Moisture from the……

  • Although soil moisture conditions are dry in many areas, seed shallow to promote rapid and uniform crop emergence. Soil temperatures should average 5°C over the coolest and warmest parts of the day. Cool soil temperatures will slow emergence, putting seedlings at more risk from seedling diseases and insect attack. As well, protection from most seed treatments starts……

  • Canola seed size can be quite variable. A sample of thousand seed weights (TSW) this spring is ranging from 2.8 to 6.0 grams per 1000 seeds. Essentially the number of seeds (and ultimately plants) in one pound of seed can vary significantly. Take note of the seed size (TSW should be marked on seed tags……
