Adjusting the number of oat seeds planted and the timing of planting can affect how well the crop grows and produces grain. A study looked at two oat varieties grown at different planting dates and densities. They found that planting earlier led to better grain yield for both varieties, but also caused fewer panicles to form. One of the varieties was more likely to bend over (lodging) when planted late and at higher densities. The best grain yield for one variety was with fewer seeds planted early, while the other variety did best with a specific density regardless of planting date. Overall, the timing and density of oat planting can impact how much grain is produced.
