Seasonal Crop Summary
September 16, 2025
Northwest Region
High daytime temperatures made for a good week of harvest progress until the precipitation over the weekend. Heavy dews have also contributed to a shortened harvest window. Desiccation/swathing continues in canola as stages are reached. Post-harvest field operations are continuing.
Fall rye and winter wheat seeding is underway, with some fields established and some acres to be seeded before the approaching deadline.
Spring wheat harvest, across the entire region, is varied due to rainfall during the season. Harvest is most advanced in the Swan Valley and Dauphin areas, while areas in The Pas and Roblin/Russell continue behind.
Initial estimated average yields are 50-60 bu/ac. with some fields yielding 70+ bu/ac. Recent precipitation events have caused some wheat to sprout.
Field pea harvest is complete. Yields vary from 30-60 bu/ac.
Canola crops continue varied across the region. Desiccation/swathing continues, with some harvest progress this week while fields move towards maturity. Harvest progress is approximately 8% complete, being most advanced in the Swan Valley region. Varied stages within some fields are noticeable with some plants at maturity and some plants still green – especially in areas of the field that had not germinated due to lack of moisture this spring.
Soybean crops are mostly in R7 stage, moving closer to maturity.
Provincial Overview
This week’s precipitation accumulations ranged from 0 mm to 106.6 mm. Extensive rains and intense thunderstorms occurred in the far southwest corner of Manitoba and in parts of the Eastern cropping region between September 11 and 12. Parts of the East near Steinbach received over 100 mm of rain in 31 hours. Flooding was reported in these regions as the majority of the rainfall fell over a few hours. The highest amount of rainfall was observed at Steinbach (106.6 mm).
Climate normals for total accumulated precipitation from May 1 to September 14 range from 237.2 mm to 365.6 mm and are based on 30-year historical data. The majority of the Southwest, Central, and Eastern regions have accumulated more than 180 mm this growing season. Total precipitation accumulations this season remain below 60% compared to the 30-year average in the Interlake and parts of the Northwest and Eastern regions. Parts of the Southwest have accumulated more than 120% of normal precipitation levels since May 1.
Soil Moisture 0 – 30 cm shows a regional representation of soil moisture conditions for the top 30 cm on September 14, 2025 relative to field capacity. Soil moisture is variable across agro-Manitoba with areas within the same regions showing very dry to wet conditions due to variable precipitation. Large areas of the Interlake continue to show dry or very dry conditions. Optimal conditions were prevalent in the Northwest, Southwest, and Central regions on September 14 with localized areas displaying wet, dry, or very dry conditions.
Percent Normal Accumulated Growing Degree Days represents the variation of accumulated Growing Degree Days (GDD) from the historical record over a 30-year period from May 1 – September 14, 2025. GDD Accumulations are between 100% and 110% of normal for the majority of agro-Manitoba.
