Maximizing soybean yields through managed inputs
Perhaps the most interesting and important finding of this work involved the oldest technology tested: row spacing. Not only did the narrow rows produce significantly greater yields than did the wide rows, but this factor appeared to be the single most important factor tested. In fact, producers considering moving back to wide rows should know that, in order to maintain yield parity with narrow row systems, they will be required to invest significant dollars into yield-promoting factors such as foliar fungicides.
Corn and Soybean Digest has developed an Apple and Android app, based on this research, to help farmers evaluate the cost of inputs relative to their expected yield response. Please search for "Extreme Beans" to find the app at iTunes or the Android Market.
