Over-night temperatures on May 22 to 23 dipped to -2 to -3 oC in many parts of Ontario. Cereal crops are hardy to light frosts. Leaf tissue on plants that have not hardened off will withstand temperatures of -4 oC or lower before the cells will freeze and damage occurs, making late spring frosts of […]
28% has become the preferred nitrogen source on winter wheat in Ontario. Application is perfectly uniform, something that seems difficult to achieve with most urea applications. However, leaf burn is one of the main problems with 28% applications, particularly at later stages of growth. With more emphasis on split nitrogen applications, and renewed interest in […]
Wheat yields pushing 150 bu/ac are very possible with good management and increased nitrogen (N) rates. Recent research clearly shows an interaction between fungicides and nitrogen. But high nitrogen rates immediately raises questions about lodging, nitrogen source, and application timing. Wheat’s nitrogen demand is much earlier than corn, so nitrogen management needs to be different. […]
Synopsis: Using the provincial performance trials to pick the top variety for your farm. By now you should have looked at the wheat variety trials (www.gocereals.ca). What an AMAZING amount of information. With new information, and combined charts, which table should you actually use? Managed or normal? For the first time ever (2013), there are variety comparisons […]
Ontario wheat performance trials are the first to add fungicides as part of the evaluation package. Years ago, no one sprayed wheat, barely even with a herbicide. Today, if you don’t spray a fusarium fungicide on your wheat crop, you aren’t a real wheat farmer. And the fusarium issues with #Harvest13 have really driven this […]
According to Environment Canada, atmospheric sulphur dioxide emissions were reduced by over 50% from 1990 to 2010. Although this is a positive outcome for emissions reductions it does signal an inevitable need to ensure that field crops have an adequate supply of this essential nutrient. A study was initiated in 2011 to determine how varying […]
Ontario research shows an average of 7.5 bushels more wheat. Add in improved winter survival and a more uniform stand and you have an agronomic no-brainer. Stooped over a seed trench late at night, squinting through the beam of a flashlight at dark grey soil, Alan McCallum still doesn’t doubt how worthwhile starter fertilizer is […]
Co-Authors: Dr. Peter Sikkema (University of Guelph) Growers looking to optimize efficiency of field operations often inquire about applying a herbicide with 28% urea ammonium nitrate (UAN) as a carrier. In theory it makes sense. An application of 28% UAN at 400 L/ha (42 US gal/ac) as a carrier with a herbicide would save a […]
With most of the winter wheat planted on time last fall, or even a few days early, we have the yield potential to take advantage of more inputs. With wheat prices at record levels, and our inputs still at last year’s prices, it’s time to GO FOR BROKE! Nitrogen – add 10 pounds to your […]
