Abstract

It is obvious that seedlings grown in dense stands can not develop so well as those grown without crowding. Nurserymen naturally wish to avoid injury to their stock from crowding, but they also desire to utilize their soil space as fully as possible. The optimum density of stand for each species and age class of nursery stock can be determined within reasonably close limits only by detailed experiments employing plant measurements, weights, root examinations, and observations of survival in the field. Such experiments were conducted at the Savenac nursery in western Montana. Preliminary tests dealt with the effect on seed-bed density of the amount of seed sown and were followed by observation on the evil effects of crowding.
