| On my farm the rows worked best mechanically running east and west, so only the end rows were north and south. I didn't notice any difference in weed growth even full till without spraying that was significant. I'm sure row width can be a shading factor as the bushiness of the beans. Very bushy beans filled in so much it was hard to walk the beans in August, but they were clean except for volunteer corn. I found the hybrid corn didn't pollinate well so there were very few kernels per cob and decided that walking the beans and chopping the corn plants from the rows was harder on the beans (and me) than letting them grow.
At the same time narrow rows or bushy beans canopy sooner and more effectively, the lower leaves on the crop get shaded too and that might have an effect on production. That open rows might yield better because more leaves get full sun. Like the edge effects especially in corn strips where they alternate with beans or a gap like in a test plot.
