Abstract

This project evaluates the survival and initial growth response of oak seedlings produced under special nursery protocols (?enhanced? seedlings) compared to nursery-run oak seedlings of the same species, and the influence of various cultural practices on these same nursery stocks. Survival did not differ significantly between nursery stocks. Significant differences in survival among competition control treatments did occur. Intensive competition control regimes using glyphosate can negatively impact seedling survival if seedlings come in contact with herbicide spray drift.Nursery-run seedlings had significantly greater growth and many were larger than enhanced seedlings after two growing seasons. Height growth was typically greater with seedlings receiving less intensive competition control, while groundline diameter (GLD) growth was greatest with seedlings receiving more intensive competition control. Subsoil and auger planting typically resulted in greater growth than normal hand planting. Fertilization improved growth in certain areas, but the effects diminished after the first growing season.
