Manitoba Harvest Getting Started 

The harvest of winter wheat and fall rye crops is underway in Manitoba, with some barley and dry pea crops also now coming off, according to the latest weekly provincial crop report. 

Early yield results are described as average, with crop conditions generally looking good to very good in most parts of the province. In total, less than 1% of the Manitoba crop is in the bin. 

Fall rye yields are reported between 45 to 90 bu/acre, averaging between 75 to 85 bu/acre. Straw volumes are high, and swathing is common. Many farmers have commented that they are intending to seed more fall rye this autumn if conditions remain favourable, especially on ground that had been summerfallowed due to excessive moisture.  

Winter wheat yield reports are between 60 to 75 bu/acre. Harvest will continue as humidity drops and weather conditions allow in the coming days. Quality has been variable. 

Spring wheat is beginning to turn colour in the heads, and kernel development is reaching hard dough in most locations. The spring wheat crop is rated mostly good to excellent, and pre-harvest application may begin in approximately 10 days on the earliest crops. Barley crops range from milk to hard dough stages, with malt crops most advanced, and greenfeed or very late-seeded fields further behind. A limited start to harvest has begun near Starbuck in the Central Region. Oat crops are reaching hard dough in the most advanced fields. 

Canola crops are variable across Manitoba, with many in excellent condition and others in poor condition with thin stands. Crop staging ranges from full bloom to swath timing (60% seed colour change). Large areas of late-seeded canola along the Yellowhead Highway (PTH 16) and north toward Riding Mountain National Park are in mid- to late bloom and require a month of good growing conditions to mature. 

Soybeans have reached the R5 to R6 stages, many fields in southern Manitoba could use a good rain soon to help fill the uppermost pods.  


Overnight low temperatures across the region have been cooler this week, while daytime highs reach 30°C. Much of the region received a good, timely rain on Monday, which will help with yield in later-season soybeans and corn. Pivot irrigation is ongoing in potatoes and some other crops where infrastructure allows. Harvest has started on winter cereals, and pre-harvest application has started on some early seeded oats. Crops look very good overall, despite areas of fields that had previously drowned-out, remaining stands are doing well. 


Good weather this week helped advance crop maturity. Precipitation over the weekend was heavy in some areas of the region while some areas received nothing. The highest rainfall recorded was in Swan Valley at 30 mm accumulated for the week, with some localized showers missing official weather stations, recording up to 50 mm. Rainfall was at times heavy over the weekend, again causing lodging in some cereals. Most mornings have had very heavy dew.  

Harvest has started for field peas in the Swan Valley, while most other crops are turning colour, and the occasional field has been desiccated. Lodging events may affect grain quality in cereal crops in the southwestern part of the region near Dauphin and Ste. Rose, since cereals are in the milk to soft dough stages. Insecticide applications for Lygus bug control have started in the Swan Valley on canola crops, while grasshoppers remain a concern across much of the region.  


Warm, seasonal temperatures dominated much of the previous week, with thunderstorms arriving Monday evening in the northern part of the region, in a band along PTH 2 and northward to MacGregor and Portage la Prairie, moving eastward to Winnipeg. Hailstones fell in the Rathwell area, damage assessment is ongoing. Crops appear in very good condition throughout much of the region, and producers are anxiously awaiting harvest and hoping to miss damaging weather systems. Many farmers are expecting to use a pre-harvest aid or swath more frequently this year, as crops are more uneven due to delayed seeding and emergence issues.  


Thunderstorms swept over the entire region Monday evening, with amounts ranging from 4 to 100 mm. The previous seven days were dry and sunny. Heaviest rainfall accumulations occurred in the Beausejour/Vivian area, with the rest of the region recording between 20 to 55 mm. Strong winds and intense downpours occurred in some areas, leaving crops lodged. Standing water and backed-up ditches are evident in the highest rainfall areas. Temperatures were generally normal to above normal, and humidity remained very high. Up until the rain, field access continued to improve and progress was being made on field operations. Haying and harvest progress will be at a standstill for the next several days.  


Winter cereal harvest has started in the region, with good yields, up to 100 bu/acre in fall rye, and 80 bu/acre in winter wheat. Drowned out areas are lowering field averages, but remaining parts of the crop are doing quite well considering the challenging moisture conditions this year. Harvest in winter cereals is expected to ramp up as the ground dries out from the most recent thunderstorm event. Canola and spring cereals remain quite green, and are at least two week away from harvest. Conditions in the northern Interlake are less favourable, with an additional two to four inches rain over the weekend on already saturated ground.
