Growth, Nutrition and Root Development of Ontario Tubelings, Plugs and 3+0 Bare-Root Black Spruce

Young stands established with Ontario tubelings, plugs and 3+0 bare root black spruce (Picea mariana [Mill.] B.S.P.) were examined and their growth, nutrition, and root development were compared. Mean height and current annual height increments of bare-root stock significantly exceeded those of tubelings and plugs. Although all stand types were moderately deficient in nitrogen and phosphorus, growth differences were associated with original tree size, root development and overhead competition.
