Increased production of soybeans in the United States has made it necessary to study the response of soybeans to various field conditions. The experiments reported in this paper were conducted in Nebraska over a two-year period (1955 and 1956) to study spacing effects on anatomical and agronomic characters. The influence of five seeding rates, two row spacings, and two seed treatments on the agronomic and compositional characters of three soybean varieties grown under irrigated conditions was studied. The characters included were yield, emergence, seed weight, lodging, maturity, protein, and oil. Then a more detailed experiment was conducted measuring the effects on two soybean varieties of four within-row and two between-row plant spacings on leaf area, stem diameter, internode lengths, plant height, yield, and seed weight.
