| gpsdude - 1/11/2026 18:52 Depending on area and yield potential if you are under 5 bu/1000 seeds you should back off on population. If you are 10 bu/1000 seeds you will more than likely benefit from more population. Since every year is different, you need to do some long term test blocks to dial in what is best for your area.
Pretty good advice overall but I'd make the window 7-10 bu per 1000 seeds dropped. If you're not getting over 7 bu per 1000 plants population is unlikely to be the limiting factor (there's a point where more plants actually hurt yield potential) and if you're getting over 10 bu/1000 you need more seed out there.
Some hybrids respond differently to population but in general 7-10 is a pretty good window. 5 bu/1000 would indicate 40k seeds and 200 bpa as being acceptable. To me, that's a lot of wasted money on seed.
