Wheat Pete's Word, Sept 14: Wide rows and fleabane, deep wheat, gray corn and random green plants


It’s farm show week in Ontario, but it’s also the very beginning of soybean harvest in the province.

The agronomy questions continue to roll in, especially for those keen producers looking to grow great wheat. In this week’s Wheat Pete’s Word, Peter Johnson has plenty of answers on perfecting wheat planting and much more!

Have a question you’d like Johnson to address or some yield results to send in? Disagree with something he’s said? Leave him a message at 1-888-746-3311, send him a tweet (@wheatpete), or email him at [email protected].

  • There is a Cleanfarms collection in Northern Ontario, September 12-16; in southern Ontario, southwestern Ontario is September 19-22, or old, unwanted pesticides and medications. Call your retailer or check here.
  • The OFCAF in Ontario has announced the second intake: January 4th to 18th, 2023. Get ready!
  • Harvest is rolling with this good dry weather in parts of Ontario
  • Some of the short season beans are disappointing
  • Corn is green to the ground still in some pockets
  • Not all abundant: at Paris, silage is half of average
  • Oxford county with lima bean yields blowing the doors off
  • What happened to the corn crop? It looked fine, and all of a sudden, it’s gone off
  • That’s drought. It could be anthracnose, but unlikely. green to gray to dead
  • Soybeans, too
  • Yield tour suggests 186.9 for corn, and 50.3 bushel soybean yield. Estimate at Wellington county 198.8 bu/ac for corn. Can Wellington county actually make almost 200 bushels per acre on a year like this? All depends on what field you visit
  • The errors in yield component estimates are not additive — they multiply. That makes it tough for anybody to predict where the final yield is going to end up
  • Complaints about green plants or green areas in edible bean fields. One green plant, and sometimes it has pods on it, sometimes it doesn’t have pods on it. This year we’re seeing it in patches in the field, as well. It’s an environmental stress
  • Could it be a temperature issue? What about drought? Microenvironment matters
  • Wheat planting is roaring along
  • It is cool for Wheat Pete, let me tell you
  • Paying attention and growing great wheat
  • Seeding rate? You have to know your optimum date
  • 1.5 million seeds/acre at optimum date
  • Going too early can be a risk, but if you go early, pull back the seeds per acre
  • Check out this cool Wheat School video on early planting date. 1o-plus bushels an acre
  • It’s about soybean management, baby
  • Under dry conditions, do you keep phosphorus rate with the seed the same? How much moisture do you have?
  • With 7.5″ rows, with 40 to 50 pounds of actual phosphorus, chances are you’re not going to get into a level where seed burn is an issue at all
  • You can cut back to 50 pounds of actual MAP or 25 pounds of phosphorus and you only generally give up a couple of bushels per acre in yield
  • How deep do we go? If you are in the dry zone, it’s likely to stay dry. If you can find moisture at two and a half inches, plant the wheat seed three inches deep or two and three quarters get it into moisture, because with warm dry conditions it will come flying out of the ground
  • On the other hand, if you have good moisture, don’t seed over an inch and a half deep
  • You go up to three inches and when it’s early like this, you get it into moisture if you can at all
  • Fleabane is a community problem (Wind-borne)
Fleabane in 30″ beans
  • Enlist bean are still green. 2, 4-D is too late on big fleabane is not good
  • No more 30″ soybeans for me! (see above)
  • Fall weed control: so critical for fleabane
  • Check out The Agronomists on Monday night, 8 pm on fall weed control
