Increased soybean (Glycine max L. Merril) seed costs have motivated interest in reduced
seeding rates to improve profitability while maintaining or increasing yield. However, little is
known about the effect of early-season plant-to-plant spatial uniformity on the yield of
modern soybean varieties planted at reduced seeding rates. The objectives of this study
were to (i) investigate traditional and devise new metrics for characterizing early-season
plant-to-plant spatial uniformity,(ii) identify the best metrics correlating plant-to-plant spatial …
