D the last few years many farmers and experi.ment station workers have realized that the amount of seed planted of many of the grasses and small-seeded legumes was far in excess of the number of seedlings obtained in the initial stand. Such experiences have probably been due to the effect of environmental influences, species of plant, depth of planting, soil type, and other less important factors upon the total emergence. Although these factors, with the exception of the environmental effects, may be controlled in part, the influences of any one of these factors or of the interactions among these factors have not been studied extensively by experimental methods. Farmers have been sowing too deeply in some cases and some of the recommendations for depth of planting grasses and legumes found in the literature involve depths which were probably too deep for maximum seedling emergence. Since a good initial stand is necessary in the establishment of meadows and pastures, it was believed desirable to determine as definitely as possible the effect of the above variables upon the primary emergence.
