Seedling Emergence of Small‐Seeded Legumes and Grasses 1

HE poor stands of seedlings frequently associated with the culture T of the small-seeded legume:; and grasses have often hindered the use of many of these valuable crops. It appears evident from the high cost of seeds, the frequency of undesirable stands, and the value of these crops to a permanent ag:riculture that a need exists for critical investigation of the factors tha$ influence seedling emergence. The results of a study of cettain of these factors are presented in this paper. Major consideratim is given to the effect on seedling emergence of depth of plantinq, mulching, kinds of crop seed, size of seed, and soil differences.
