I used to plant in 38 inch rows, didn"t like that. Got a 15 inch planter, pretty happy with it. Neighbor likes his drilled beans, says they do best for him. Other neighbor was at 30, went to drilled, went back to 30, now he has a twin row planter, think he"s happy with that now. Minnesota, clay or peat soils with above average ph, not too favorable to beans no matter what spacing. I think whatever you feel comfortable with is going to work well for you. Whatever you like tweaking with to make it work. In the wrong rain, y clay will crust over & be hard on emerging beans in drilled conditions. Tend to "spill" beans and use more of the expensive seed than with a planter, but canopy might hold back weeds & an additional spraying. White mold can be a problem here. Wide rows of 30 or 38 you can have weed issues esp on a short growth year. Need to look for bushy beans, less of them around these days. I knida like my 15 inch, try for the best of both worlds, approach. If I were a big farmer with $$$ that twin row for corn & beans doesn"t look too bad next door, I"d have to seriously consider that. --->Paul
