The 2021 6th Annual Great Ontario Yield Tour toured across Ontario from August 16th – 27th, 2021 collecting over 1,000 corn and soybean samples. It looks like it’s an all time
record high for corn with an estimate at 191.5 bu/acre! (Last record high by Agricorp was 2018 at 183). The tour estimated the soybean yield at 51.7, just shy of the record at 53 also in 2018 and 2020 at 52. The 10-year average sits at 174 and 46 bu/acre respectively.
Both crops were very mature 1-2 weeks ahead of schedule with hot spots of white mold in soybeans and WBC in corn. The west was wet but as you travelled east it was dry. A dry August and a poor finish could result in less kernel and pod weight but there is no stopping a record corn crop says Greg Stewart, Chief Agronomist for the tour.
