Abstract
The effects of two soil mixes, three fertilizer regimes, and two day-lengths on growth in containers of four half-sib families of northern red oak seedlings were studied. Maximum growth over 15 wk was produced using 3 fertilizations per week with a modified Ingestad solution, a peat-vermiculite (or perlite) soil mix (1:1:1), and an 18-hr daylength. The effect of families was significant (0.01 level) for most variables studied. North. J. Appl. For. 5:153-155, June 1988.
