How much does lodging affect yield? It all depends on when the crop goes down.
Evidence of that is showing up on Ontario yield monitors in the winter barley fields and will be coming to a wheat field near you in the coming week, says Peter Johnson, host of Wheat Pete’s Word.
The other thing showing up is the impact of compaction, especially on headlands. Compaction leads to stunted, struggling roots and the evidence of that in the corn crop is staggering. Will the crop recover? What’s the plan for decreasing compaction? Check out that discussion and much more, below!

Summary
- What happens when a Canadian farmer goes to England and meets a Danish farmer? They talk about Wheat Pete’s Word!
- Ankle-high by first of July? For some corn, it’s not been a great week
- Other corn is kid high!
- Wheat harvest is beginning in earnest in some areas of southern Ontario
- Winter barley yields are good, but the ground conditions are not
- Growing crops are using water….but maturing crops have done what they can. Don’t delay harvest!
- Barley heads can get so heavy the peduncle can break, especially in poor weather
- Lodged barley (lodged at heading vs early), early lodged cut yield by nearly half
- Cool, cloudy weather extended grain fill period — but not big kernels because of cloudy conditions. Needed sunshine
- The straw yields are over the moon. Harvest index isn’t going to be as good (grain/biomass ratio)
- PGR and herbicide going on in parts of Western Canada. Big leaves!
- Compaction at the headlands is extreme in some areas
- Yellow corn in some areas, and coming back if the roots have gotten through the compaction thanks to moisture
- Get better tires or switch to tracks, double the tile on the headlands
- Watch outs: tar spot in Michigan, but not yet found in Ontario
- Tar spot needs 6 weeks
- Later planted corn may be at highest risk (before VT timing)
- Scout, scout, scout
- Soybean aphids on June 27: keep monitoring
- N on corn now? Nitrate sample timing? Interpretation of results. What happens if it says “apply 0?” Waist-high corn? Too late
- Rapid growth stage sucks up all the nitrate in the soil! And levels of nitrate will go to zero. Earlier is better
- Fungicide on beans: a North Dakota study confirms that soybean canopy matters! One pass: R2.5, Two pass: R1-ish much earlier and then 2 days later. Consider the canopy, however!
- Enlist or Enlist Duo: remember volunteer corn control has to be a separate pass
- Watch out for next year: growing Enlist corn? It’s resistant to the fops
- FHB index and timing harvest
- As the wheat matures, it gets harder to do
- What about a pre-harvest pass on wheat? It’ll save you 2 days, and that might be worth it, but you have to scout for FHB level and have a physiologically mature crop. Lower infection won’t be worth it
- Leftover wheat seed: don’t need to re-treat, but test for germination
