Alternate row multistrain culture was studied in the soybean ( Glycine max L. Merrill) separately for maturity groups I and II using four Genotypes in each group. Two spacings between rows, 46 and 91 cm, were used during three years, 1965, 1966, and 1967. Seed yield averaged over genotypes was significantly greater when a genotype was bordered by other genotypes than when self bordered for group I genotypes only in the narrow but not in wide row plantings. Seed yield of alternating row plantings was lower than that of the best component with the exception of group I with narrow rows. Increases in seed yield of alternating rows of two genotypes as compared to the mean of pure stands were generally greater for single than for double alternating rows. Variance components for genotype combinations ✕ years indicated that the yield of alternating row plantings of two or three genotypes were more consistent from year to year than those of pure stands.
