We are still on 36" rows, as is much of our area. Four years back we bought a brand new planter and fought over the choice of whether to change to 30" or stay with 36". After thinking a long time we stayed. We consistantly yield just as good as, if not better, than our neighbors with 30". With no increase, how could we justify all the iron purchases that would be neededIJ 20" rows have been tried in this area, but have not done as well as hoped. This spring we are planting our corn at 29200, which gives a spacing of about 6.1-6.2 inches between seeds. Our beans are planted in 18" rows at about 170K. NW Illinois
