The effects of plowing and tilling, fertilization, and chemical weed control on survival and height growth of newly planted seedlings of black locust, silver maple, white ash, white pine, and white spruce were investigated in a non-replicated study in southern Ontario. Cost-benefit relationships of treatments were computed. Plowing and tilling improved growth of all species with average increases ranging from 37 per cent for white spruce to 750 per cent for white ash. Plowing and tilling plus weed control greatly improved growth of all hardwood species and resulted in the most favourable growth-cost relationship. Fertilization improved growth of locust, ash, and maple by 200, 500, and 700 per cent respectively, but failed to increase conifer growth. Application of 12 pounds of simazine increased ash mortality by 67 per cent. White spruce was subject to severe frost heaving following complete weed control.

Abstract Nearly 20,000 acorns of Nuttall oak (Quercus nuttallii Palmer) were direct-seeded in Sharkey clay soil in the Mississippi Delta. Acorns sown 1 inch deep in January gave significantly better germination, 55 percent of total sown, than did eight other combinations of three storage treatments with three sowing depths. Rodents destroyed most acorns sown in the understory and in forest openings <1/10-acre but hardly bothered acorns sown in 350-foot square forest openings cleared to ground level. After 10 years in the larger areas, 75 percent of the seedspots, spaced at 5- x 10-feet and sown with four acorns each, were stocked with one or more living trees. About one-third of the oaks were in a free-to-grow position. Average height and d.b.h. of the largest oaks, one from each of 162 treatment rows, were 17.8 feet and 1.8 inches. Five-foot wide strips were mowed between the 10-foot spacing. After 10 years, there were 14,142 total trees per unmowed acre.
