Central Nebraska | We used to plant beans on 36" single rows, have now gone to twin row beans on 36" centers. You can raise really good beans on 36" rows, just have to do your homework on varieties. Bushy varieties will work, and so will tall ones. We actually usually went with the taller varieties as they shaded the row really well. I'm not sure what you plant for bean population, but we have gone from 160,000 to 135,000, and haven't seen a yield drag. If you check your fields often and spray them at the right time, you won't have any more weed pressure than you would've with 30" rows. For us, with the taller varieties, we would either cultivate once and spray once, or spray twice. And raise just as good of beans as the 30" neighbors. We're wide rows because of gravity irrigation, but we have some neighbors that went from 36" to 30" rows and have not seen a benefit (other than growing seed corn) yield wise, so I don't think we'll go that way anytime soon. | |
