The relationship between seeding rate and harvest population. Ideally, we would like to have every seed planted be present at harvest; this would signify a 1:1 ratio. Most hybrids have a 95 percent germination rate, which means that each seeding rate should parallel the 1:1 line, except that it would be slightly below it. As the seeding rate increases though, the final populations start to drag down from the 1:1 line.
