Manitoba Crop Report and Crop Weather report: No. 20

Conditions as of September 12, 2016

Wet weather over the past week slowed harvest progress in Manitoba.

The recent weather is also impacting crop quality in spring wheat and barley. Some crops are being harvested at tough or damp moisture levels, requiring aeration or artificial drying to achieve safe storage moisture levels.

Soybeans, grain corn and sunflowers are maturing quickly. Silage corn harvest continues, and the first acres of soybeans have also been harvested.

Seeding of winter wheat and fall rye continues, with the earliest seeded acres emerging.

Southwest Region

Rainfall over the past week limited the amount of harvest completed in the Southwest Region. Producers resumed harvest on the weekend; however, rainfall again limited the amount of acres harvested. Rainfall amounts varied with amounts of 10 to 20 mm reported.

Producers are planting winter wheat and fall rye with ideal seeding conditions. Cereal harvest is approximately 70 per cent complete with hard red wheat being the majority of the acres remaining. Canola harvest has started with 30 per cent of the crop harvested with average yields. Flax is ready to harvest in most areas with producers waiting for favourable conditions.

Most soybeans are in the R7 stage with some reaching the R8 stage; there are very few issues reported in soybeans. Sunflowers are in the R7 stage with some reports of disease starting to show up. Corn silage has begun and yields are above average.

Several producers are doing second cut and hay condition is average. Pastures are starting to dry down for the year.

Northwest Region

Cool, wet weather throughout the week impacted harvest operations in the Northwest Region. General rain in The Pas area resulted in 50 mm of rain and wet conditions. There were scattered showers and unsettled weather into the weekend in the Dauphin area as well. These spotty showers kept harvest progress minimal and very much location specific. Roblin area was much the same with showers over the weekend and up to 25 mm of rain in some areas. Swan River received 17 to 25 mm of rain on Wednesday but by the weekend harvest resumed. Showers on Sunday evening again halted harvest operations. With the exception of crops in those areas impacted by too much moisture, most field crops throughout the region continue to mature and are in good to fair condition. Cooler temperatures and heavy morning dews also reduced the available harvest time window.

Crops are advancing with the spring wheat crops 90 to 95 per cent mature and harvest operations occurring, as weather permits, throughout the region. The red spring wheat harvest is wrapping up in the Swan River and Dauphin areas, 30 per cent in Roblin and 60 per cent in The Pas. Much of the grain combined over the last week has required drying. Yields are variable ranging from 50 to 70 bu/acre. The majority of the barley is standing with the exception of the Roblin area where approximately 30 per cent of the barley acres are combined. Approximately 10 per cent of the oats in the Swan Valley is combined and 50 per cent swathed, while 30 per cent is combined in the Roblin area.

Canola continues to develop with most canola in the region mature and much of it swathed. Some straight combining has occurred around the Dauphin area. In Swan Valley 20 per cent of the canola is combined, 90 per cent is swathed in the Roblin area and 75 to 80 per cent is swathed in The Pas area. Field pea harvest operations are generally complete. Some post-harvest fieldwork has taken place, dependant on time and weather conditions.

Late seeded cereals were chopped for silage last week. If weather allows, additional greenfeed will be harvested this week. Putting up native hay remains a challenge due to excess moisture. Some producers waiting until after a killing frost to take second cut alfalfa hay off. Corn silage harvest remains a week to two weeks away. Pastures are in decent condition for this time year.

Central Region

In the Central Region, near seasonal temperatures through the week helped crop growth and maturity. Relative humidity, although variable, continues to be high much of the time. Harvest progress has been slow to moderate, dependent on local conditions. Areas that received the highest rainfalls on the September long weekend are still at a standstill. Unsettled weather continues; all areas received showers that interfered with harvest and haying operations. Accumulations for the week were 10 mm or less for most.

Harvest in the Central Region is estimated at 60 to 75 per cent complete, dependent on mix of crops in the area and cooperation of weather conditions. The majority of the cereals are harvested. Drying and aeration is required for some harvested crop. Hard red spring wheat yields range from 30 to 75 bu/acre, to date, and CNHR varieties up to 90 bu/acre. Protein is variable, with early reports of 12.5 to 15 per cent. Fusarium damaged kernels are being reported as variable, ranging from quite lows of 0.4 to as high as 4.2 per cent. Barley yields are in the 70 to 100 bu/acre range; some has made malt, but reports of higher fusarium damaged kernels and vomitoxin levels are a concern. Fusarium head blight has also been an issue in fall rye, limiting marketing options. Oat harvest continues, with yields also impacted by excess rains. Yields range from 80 bu/acre to as much as 140 to 175 bu/acre and more, where excess moisture wasn’t an issue. Bushel weight is average to light.

Harvest of canola continues. More canola is being straight cut than in previous years. Canola yields range from 10 to over 50 bu/acre, with average to date in the 30 to 40 bu/acre range. Acres completed range from 50 to 90 per cent, depending on the area. Flax is being harvested, with initial reports in the 25 to low 30 bu/acre range.

Corn has grown rapidly; most fields are in the R5 (dent) stage. Soybeans range from R7 to R8, with significant leaf colour change and leaf drop. Harvest may start this week in the earliest maturing fields. A few seed fields have been harvested. No yield reports as yet. Harvest may resume in edible beans later this week if dry weather conditions return. Early yields are slightly below average, ranging from 1200 to 1800 lbs/acre. Quality so far has been good. Sunflowers are flowering and as advanced as the R8 stage and turning colour. Potato digging has started. Yields are above average and quality is average.

Winter cereal seeding continues where field conditions allow. Conditions have been good with warm soils and decent topsoil moisture for an early establishment. Producers are hoping to put in additional acres if conditions improve. Anticipated acres will be similar to last year’s seeded acres.

Straw is being baled and removed from cereal fields. Fall tillage continues.

Most second cut hay is complete, as is first cut wild hay. Second cut is providing a much denser, better quality hay. High humidity is an issue for drying of swaths. Many producers are wrapping bales. Forage growth on pastures has slowed, and some is rated fair or poor. Livestock water supply is adequate.

Eastern Region

In the Eastern Region last week, daytime temperatures were cool to seasonal with some night time temperatures getting down to 5oC or lower. Rainfall accumulations varied from 5 to 30 mm with higher accumulations occurring in southern and central districts. Rainfall events were highly variable both in terms of intensity and location. Given the heavy rainfall that had occurred across the Eastern Region the previous week, field operations were halted for almost all of last week as producers waited for fields to dry up enough to allow access. Weather conditions did allow for drying but were not ideal. Remaining spring cereals and canola were ripe and ready to combine. Cereal crops that have remained out are seeing some quality degradation. Producers are anticipating progress on remaining cereal and canola acres if good drying weather occurs this week. However, areas that have experienced persistent excess moisture throughout the growing season are expecting delays before harvest and fieldwork can resume. Crop yields in these areas have thus far been significantly lower than Eastern Region averages.

Harvesting of spring wheat is about 90 per cent complete. Yields ranged from 50 to 75 bu/acre with an average yield of 60 bu/acre. Quality was good with much of the crop being graded as #2. Fusarium head blight levels are lower than expected. Canola harvest is estimated at 65 per cent complete. Yields range from 25 to 45 bu/acre range with an average yield of 30 bu/acre.

The soybean crop is mostly at the R7 growth stage with brown pods evident, although some fields with early maturing varieties achieved physiological maturity (R8) and were proceeding with dry down. Sunflowers are in the R8 to R9 growth stages. Corn is at R5 (dent) stage.

Across the Eastern Region, the majority of pastureland is rated in good condition. Availability of livestock water is adequate. There was not much movement on haying last week as everything was wet from the rains. By the end of the week, second cut hay was getting mowed. Winter feed supplies are rated as 20 per cent surplus and 80 per cent adequate for hay and 100 per cent adequate for straw, greenfeed and feed grain.

Interlake Region

Seasonal temperatures along with scattered showers delayed harvest once again throughout the Interlake Region. Producers however were able at times to get back onto the fields to continue harvest towards the end of the week. Precipitation amounts vary from 5 to 10 mm of rainfall and in isolated areas rainfall amounts vary from 15 to 20 mm.
Harvest is estimated to be 50 to 60 per cent complete. The majority of spring cereals and canola acres have been harvested except for later seeded fields. Spring wheat yields vary from 50 to 60 bu/acre, oats 90 to 130 bu/acre and barley 60 to 80 bu/acre. Canola yield is estimated to be around 40 to 50 bu/acre in areas where excess soil moisture wasn’t an issue and 10 to 30 bu/acre where moisture issue did occur. Soybeans continue to drop leaves and turn colour as they reach maturity. In the south Interlake, harvest of soybean fields around Winnipeg have started, and harvesting should be starting this week in the Stonewall area as well. Corn is in the R5 (dent) stage and sunflowers are in the R7 to R8 stages. Alfalfa seed fields continue to be desiccated or swathed as plants reach maturity.

Earlier seeded winter wheat has started to sprout and emerge. Fall tillage has begun and in some areas majority of harvested cereal and canola acres have been worked.

Producers continue to ensile greenfeed and alfalfa/grass stands. Some native and grass hay is too wet to travel on as the low lying areas are flooded. Pasture growth is slowing with shorter days and cooler temperatures. Generally, there is adequate pasture growth for the time of year. There is also adequate water for livestock consumption.
