High yield soybean research was conducted at the Milan Research and Education Center, Milan Tennessee from 2014-2016 to evaluate low and moderate seeding rates, row configuration and a split application of nitrogen applied at R1 and R3 stage soybeans to two cultivars under irrigation. Low seeding rates yielded close to moderate seeding rates due to increased pod production for both varieties. Narrow row and 2:1 skip row configuration outyielded a wide row configuration and increased yield at similar seeding rate was due to higher pod production. Narrow and skip row configuration yields were essentially the same at similar seeding rates. The addition of nitrogen increased seed weight and yield, although amount of yield response was not enough to return cost of nitrogen.
