New Edamame Planting Guidelines Could Improve Profits

USDA Agricultural Research Service (USDA-ARS) and University of Illinois researchers say that planting machine-harvested edamame at half the rate currently suggested by seed companies could improve producer profits. Based on a test of four cultivars at five different densities, researchers say the economically optimal planting density ranges from 35,200 to 48,600 plants per acre. This rate reduces seed costs and produces plants more suitable for machine harvest and with less vegetation per pod. The research underscores the point that edamame are not produced the same way as grain-type soybeans.
