Seven soybean [Glycine max (L.) Merr.] cultivars grown at three different seeding rates were studied in 1969, 1970, and 1971 to determine the influenee of seeding rate on components of seed yield. A correlation and path coefficient analysls was made to determine the direct and indirect effects of seed components on seed yield. Pods per unit area and seeds per pod had the greatest effect on seed yield in five and four of the nine sets of data, respectively.

The soybean was found to have the abillty to compensate for differences in stand. Compensation was accomplished primarily through number of pods per plant. In general, yield components were negatively associated with each other.
