Abstract
Abstract Soybeans (full‐season cultivars Amsoy and Wayne) were sown in narrow (15 em) rows in seeding rate trials on 3 sites in late spring 1977 in Northland. Plant populations in each trial ranged from 5 to 110 plants/m 2 . As seeding rate was increased, plants were taller and displayed greater internode length, a reduction in node number, and the first pods were set on higher nodes. There was a marked reduction in pods per plant as seeding rate was increased, but only a slight decrease in seeds per pod and no effect on seed weight. For Wayne, the better adapted cultivar, an ‘optimum’ plant population for grain yield was displayed at about 30 plants/m 2 at 2 sites, and 60 plants/m 2 at a weedy site. Amsoy displayed no evidence of an optimum plant population for grain yield.
