Producers who participate in AgriInsurance provides seeding date information to Manitoba Agricultural Services Corporation (MASC). This dataset provides us a historical perspective of when seeding has taken place in the past. Seeding date data information is broken down into a week:month format, i.e. 1:05 is Week 1 in the 5th Month (May). So 2:05 is Week 2 in May, and so on.
Each week is then categorized dependent on the day of the week in which the month starts. So if Week 1 starts on a Sunday, there will be 7 days of seeding captured in Week 1. However, if Week 1 starts on Friday (like we have in 2015), there are 9 days captured in Week 1. Confused yet? Essentially, each year will have a different number of days captured in each weekly timeframe, varying from 5 days up to 12 days. However, the data still provides good reference points to seeding progress in Manitoba.
In Table 1, cumulative seeding progress to the end of Week 1 in May for six crop types is provided. The last five year (2009-2013) average cumulative seeding progress is noted, along with what was seeded in the same timeframe in 2014. Please note that data is for final insured crop in the ground.
Table 1: Seeding progress (%) in Manitoba by end of Week 1 in May (1:05).
Based on the May 11th Manitoba Crop Report, overall seeding progress is estimated at 55% complete. There isn’t a provincial breakdown provided of seeding progress by crop type, but in looking at each region, seeding of spring cereals is ahead of the 5-year average of 2009-2013, and well ahead of 2014!
