Crop Report: Issue 17, August 21, 2017


Weekly Provincial Summary 

    ·                 Warm temperatures continue to advance crops quickly. 
    ·                 Rain fell throughout the province, but most areas received limited amounts and more is still needed. 
    ·                 Harvest of winter cereals and peas is nearing completion. Spring cereal harvest continues, and canola is starting to be harvested in the central region.
    ·                 Haying continues, but in dry areas there is minimal re-growth.  Rain is needed to improve pasture conditions. 
    Southwest Region
    Temperatures were above normal throughout the week.  With the exception of Birtle and Deloraine, which received 20 mm of rain, most of the region received less than 3 mm of precipitation.  
    Winter cereal harvest is wrapping up with average yields and good quality reported.
    Spring cereal harvest has started.  Barley yields are slightly above average with good quality and test weights. Spring wheat yields are average.   
    The majority of peas have been harvested with above average yields and good quality. 
    Canola is being swathed, but harvest has not started.   There are reports of spraying for Bertha armyworm but spraying has decreased since last week. Canola disease levels are very low.   
    Flax is at the ripening and drying down stage.  There are no major disease issues in flax.
    Soybeans are in the late R5 to R6 stage.  Fields in drier areas are starting to show moisture stress and are prematurely drying down. Corn and sunflowers continue to develop with very few problems.
    Most producers that were planning a second cut of alfalfa have completed it and yields are about average. Pasture land continues to rebound but fields that were overgrazed during dry periods are done for the year. Cereal silage has begun with reports of average to slightly above average yields.  
    Northwest Region
    High daytime temperatures continued through the week with crops continuing to advance to maturity throughout the region.  Dry conditions continue as precipitation was limited to trace isolated showers.   Most of the region is dry with very dry soil moisture conditions to the 61 cm depth in the Roblin area.
    Pre-harvest operations are well underway across the region as crops ripen and conditions allow. Crops are generally in good condition with the exception of areas of the region suffering from extremes of moisture.
    Combining continues in winter wheat and early seeded barley.  Spring wheat is 50 to 75% ripe, with the remainder at the dough stage. Approximately 90% of the canola is podded with 50% reaching the ripe stage.  Swathing is underway.   Soybeans are podding; however, the dry weather is slowing pod formation. Pea and lentil crops have ripened and harvest is ongoing; there are reports of pea yields ranging from 60 to 80 bu/acre in the Swan River area. Flax is in the boll stage.
    Second cut of alfalfa continues, with newer stands yielding well particularly in the Swan River and Dauphin areas.  In drier areas across the region, there may not be enough second cut regrowth to mechanically harvest.  Silage and greenfeed harvest is ongoing.  Yields range from average to above average depending on the amount of moisture received.  The majority of silage corn crops are in the milk stage.  Silage corn is holding up reasonably well considering the drier conditions, with the exception of a couple fields showing visible signs of drought stress around Roblin.  Rain is still required to improve pasture conditions in the majority of the region.
    Central Region
    Warm temperatures continued throughout the week. Scattered rains amounted to less than 10 mm of rain for most of the region.    Amounts up to 15 mm were reported in the southwest corner.   Some crops are ripening prematurely due to lack of rain.  
    Harvest is complete for winter cereals; early yields are reported as 75 to 110 bu for fall rye and 50 to 80 bu for winter wheat.  Quality is good, and FHB is low. Test weight is good, as are falling numbers for rye.   Lower yields are due to winter injury.
    Staging for pre-harvest applications in cereals is ongoing, and swathing continues as crops mature.   In some cases grain looks ripe while stalks are still quite green.   Good harvest progress was made on cereal crops last week, with as much as 40% complete.  Early yield reports: hard red spring wheat 55 to 85 bu; northern hard red wheat 80 to 95 bu; barley 75 to 120 bu; oats 110 to 180 bu. Quality and test weight are generally reported as very good.
    Canola harvest has begun, early yield reports are good. Early seed colour change is evident in the later seeded fields.   Swathing and pre-harvest applications continue with the majority of acres complete.  Sunscald is making fields look riper than they are.  Swathed canola is rapidly drying down. 
    The majority of corn is in the grain filling stage; ranging from blister to milk. Earliest seeded and earliest maturing varieties are starting to dent.
    Most peas are harvested, with yields ranging from 50 to 90 bu. 
    Flax fields are in full boll, and turning brown.  Straw is starting to turn.  
    Soybeans are in the R5 and R6 stage, with the earliest maturing varieties at R7 and the start of leaf colour change. Some soybeans are reported at R7 on knolls and ridges and are drying out, not turning. Dry conditions have resulted in some upper pods not filling.    Many fields are reaching the stage where soybean aphid is less of a concern, although a jump in numbers resulted in fields being sprayed in the Portage area last week. Soybean aphid numbers are starting to decline.  Spider mites and white mould were also found in some areas. Yields are expected to be lower than last year.
    Early types of edible beans are seeing some leaf drop as a result of drier conditions. Rainfall may benefit the later types with improved seed size.  White mould is being found in dense canopy areas. 
    Sunflowers are at the late stages of flowering; with many at R6 and early ray flower drop.  Some basal stalk rot is evident.
    Some potato fields have been topped in preparation for harvest.
    Grasshoppers are being found in fields, especially in drier areas.  Monitoring continues, and some control measures have been taken where crop injury warrants.
    Straw is being baled and hauled off fields.
    Most second cut hay is complete.  Yields are down due to dry conditions. Some fields were browning due to the lack of moisture. First cut was better than expected but was still slightly below average. Wild hay harvest continues. 
    Pastures are dry and turning brown; while some are still in good shape, as many as half are rated poor to very poor. Rain is needed to sustain pastures and livestock into the fall; supplemental feeding may be required earlier this year.
    Livestock water supply is adequate, but some rain would benefit dugout levels.
    Eastern Region
    Warm temperatures continued. The Northern and Central part of the region saw isolated showers and thunderstorms with rainfall amounts ranging from 2 to 10 mm.  Overall crop development continued at a good pace and crop condition was rated as good.  Soil moisture conditions on cropland across the region were rated as 75% adequate and 25% short.  Soil moisture conditions on hay and pasture land were rated at 30% adequate, 40% short and 30% very short.  The driest soil conditions are in the southern districts.
    Pre-harvest herbicide applications on cereals were completed last week and harvest has begun.  Harvest progress was greatest in southern districts where 50% of spring wheat and 20% percent of oats were harvested.  In central and northern regions about 15% of spring wheat and 15% of oats were harvested.  Limited yield reports received so far suggest 50+ bu/acre for HRS wheat and 100+ bu/acre for oats.  In northern regions, quality concerns in HRS wheat included low protein levels and the appearance of piebald kernels. 
    More than 60% of canola acres in the region received pre-harvest herbicide applications.  Swathing continued last week with the majority of the crop intended for swathing now cut.   
    Corn is at the blister/milk stage. Soybeans are at the R6 growth stage with crop condition still rated as good.  Sunflowers are in the late R6 to R7 growth stages.  Low disease and insect pest levels continue in the sunflowers.
    Pastures are drying up.  Livestock are grazing lower areas and some producers are starting to feed on pastures.  Haying was coming to an end on grass hay fields and some producers were looking at taking a third cut of alfalfa.  Dugouts continue to be low.
    Livestock winter feed supplies were rated as 20% surplus and 80% adequate for hay and straw, and adequate for greenfeed and feed grains.  Pasture conditions was rated at 50% fair and 50% poor.  The availability of livestock water is rated as adequate.
    Interlake Region
    High temperatures continue to advance crops quickly.   Rainfall throughout the region varied from 2 to 32 mm in the last week. 
    Swathing continues in canola in the south Interlake, with the majority of intended acres down.  Swaths are turning rapidly with hot dry conditions.  Pre-harvest applications are being done ahead of straight cutting.  In the north Interlake canola swathing is just starting. 
     Soybeans are mostly at the seed development stage (R4 to R5).  There has been a significant jump in soybean aphid numbers in the last week in the Teulon area.  Some spider mites are being found in soybeans, but the numbers are low. 
     Corn is in the grain filling stage; ranging from blister to milk. Flax bolls are turning brown, and straw is starting to turn.   Field peas are mostly harvested with average to above average yields.  
    Pre-harvest applications and harvest of cereal crops continues with average to above average yields in the spring cereals and good quality. 
    Soil moisture conditions across the region on cropland are rated as 60% adequate and 40% short, while conditions on hay and pasture are rated as 30% adequate and 70% short with the driest soil conditions in the Lundar/Eriksdale areas. 
    Second cut haying continues, where re-growth allows, with yields ranging from 0.75 to 1.5 tons/acre. Many fields do not have enough regrowth to warrant a second cut.  First cut was 1.5 to 3 tons/acre on alfalfa/grass hay.  Native hay is also being cut with yields of 0.75 to 2 tons/acre.  Many lowland acres that have not been cut for several years are being harvested due to drier conditions.
    Pastures are rated as fair to good and could use a good rain.  Dugouts are 40 to 60% full.
