Abstract
Soybean production in narrow rows is not a novel idea. Wiggans (1939) reported yield advantages of drilled soybeans in narrow rows (8-inches) over soybeans planted in 28-inch rows. However, farmers, consultants, and extension agents face a bewildering array of information regarding optimal row widths intended to maximize return from corn and soybeans during a growing cycle. This information is further complicated by the choices of planting equipment specialized for certain row widths. That soybeans planted in narrow rows generally out-yield soybean produced in wider rows is well documented. However, what is not clear is which narrow row width consistently and significantly outperforms other widths, yield-wise and return-wise, in which regions (Devlin et al., 1995).
