ANY varieties and strains of soybeans differing in numerous M characters frequently are tested together in rod-row nursery yield trials. Although much care may be taken to obtain comparable stands, there may be considerable variation in stand among different strains, or even within strains in different replications. Published data on the influence of plant spacing on different varieties of soybeans in nursery trials are very limited. To study the effects of plant spacing of soybeans on yield and several other characters commonly obtained in the evaluation of varieties, an experiment on spacing was carried out with four varieties of soybeans at Lafayette, Ind., by the U. S. Regional Soybean Laboratory3 and the Purdue University Agricultural Experiment Station, ~ooperating.~ The work was conducted over the 4-year period from 1938 to 1941, inclusive. Wiggans5 found that the soybean plant has the ability to make wide adjustments to space and that optimum rates and spacings for soybeans should be determined not only for the various soybeanproducing areas but also for the varieties to be grown. .
