November 3, 2020 - Report summarizes three-year results of a trial initiated in 1982 to compare different undercutting treatments (once, twice, or three times) in the nursery. Results indicated small or no difference in survival or height growth after any of the treatments.
November 3, 2020 - Report provides findings from 57 black walnut planting studies installed across Virginia between 1967 and 1974 where the effects of initial seedling size, competition control using herbicides, fertilization, and coppicing after planting were studied.
November 3, 2020 - Report provides results from a study repeated in 1984 and 1985 to evaluate sowing loblolly pine seed at the New Kent Nursery at depths of 0, 1/4, 1/2, 3/4, and 1 inch. Seed at depths of 1/4 to 3/4 inches germinated best, and speed of germination was inversely correlated with sowing depth.
November 3, 2020 - Report summarizes growth and survival data for three years after planting of seedlings that were undercut, laterally root-pruned, and top-clipped in the nursery beds.
November 3, 2020 - Report provides results of studies in 1976 and 1978 to test the efficacy of potassium fertilizer to induce earlier dormancy in nursery seedlings.
November 3, 2020 - Report summarizes findings from three paired plots released from hardwood competition by hand chopping at age nine and measured through age 23. The basal area and volume response to release varied widely, but, on average, released plots had 18% more basal area and 15% more volume than check plots.
November 3, 2020 - Report summarizes findings from eight plots released from hardwood competition by hand chopping at age five and measured through age 18. Released plots averaged 16% more basal area and 27% more volume than check plots.
November 3, 2020 - Report summarizes data and prediction models for estimating seed yields per cone of 20 different coastal plain and piedmont cones in the DOF loblolly pine seed orchard.
November 3, 2020 - Report provides three-year results from a study comparing loblolly pine seedlings root-dipped in water, kaolin clay suspension, and Agricol, and exposed to the sun and air for 0, 30, 60, and 90 minutes prior to planting.
November 3, 2020 - Report provides eight-year height growth of planted and direct seeded loblolly pines on piedmont and coastal plain sites.
