I didn't plan on doing a planting date trial but I left the half width disconnect off leaving 2- 30ft unplanted passes on very sandy soil. The neighbor filled them in for me with the same variety. Right side planted April 28th, left side planted May 28th. Pod counts on early planting averaged 36 pods per plant, late planting 29 pods. This would be about a 10 bushel per acre advantage on the early planting. We will see what the weigh wagon has to say in about a month.
