The Ins and Outs of Potato Yield Monitoring

Bill Menkveld, vice-president of sales and marketing for Greentronics, has never met a grower who isn’t interested in yield maps. He says producers are often surprised by the results. “Growers are always amazed to see how much yield changes across a field. It’s not uncommon to see yields vary by a factor of 100 or 200 per cent,” he says. Yield monitors provide information about crops and production practices and are designed…

Manitoba Crop Production Report Oct. 11

Again, the rains in the week (Tuesday, Oct. 1 to Monday, Oct. 7) were extensive in distribution in the province, but slightly less than last week. The weather station sites recorded 1/2” to 3/4” rainfall.  The air temperatures have generally cooled down, while overnight below freezing temperatures have started. The western areas of the province have received close to 140+ per cent of the normal rainfall. Soils are now saturated. The maps below…

Ontario Crop Production Update Oct. 11

Sunny, balmy weather this week allowed growers to make lots of progress with the harvest.  Many growers have finished digging. According to Mark VanOostrum, 80 per cent of the chipping crop has been dug.  The size profile is better than expected, and the quality is very good.  Rainfall was below average in June, July and August in the Alliston area, which resulted in poor crops in non-irrigated fields. I visited P &…

What To Do When Frost Hits

When a pre-harvest hard frost hits — a temperature of -2.22 C or below — growers are faced with some thorny challenges. While a light frost may only damage the tubers in the top part of the hill, a severe frost can take out much more. There has been early frost three out of the last 10 years in the Maritimes, and outof those incidents, last year was the worst for frost-damaged…

Black Cutworm Alert for Late-Planted Fields in Ontario

Yesterday, I checked a variety trial near Alliston that was planted late, on May 27. There was a moderate to high population of small black cutworms in the plots of late varieties, those that still had green foliage. Although the worms were small, there were also tubers with feeding damage. Small larvae of the black cutworm feed on the foliage in the evenings and remain buried in the soil near the plants…

Ontario Potato Production Update: Sept. 3, 2019

Harvesting fresh market and field fry potatoes continued over the long weekend.  Quality of both are very good, but yields are variable depending on the field. The storage crop is being top-killed according to the planting date. The spore traps keep detecting DNA of late blight in Dufferin, Simcoe and Norfolk Counties. This is a very important alert for growers in Dufferin County where there are still fields that will need at…

Ontario Crop Production Report: August 20, 2019

Finally, the Alliston, Ont., area that was hit hard by the summer drought received a much-needed rain over the weekend.  Mark VanOostrum had the details: North of Alliston 0.5 inches Alliston to Beeton 0.7 to 1.0 inches Shelburne to Orangeville 0.8 to 1.2 inches South 401 spud lane 2 to 3 inches The rain will take the pressure off irrigation for a few days and should help bulking the chip processing crop….

Ontario Crop Production Update August 10, 2019

According to Mark VanOostrum, the harvest of the early processing crop is going well. The yield is average, solids are slightly higher and a little bit of common scab is showing up. I am not surprised to hear about scab this season; common scab is more aggressive in dry years. It appears that the  beneficial bacteria, which compete with scab, suffer more than scab when it is dry. This results in more…
