  • Influence of nitrogen form ratio and calcium on greenhouse and field performance of watermelon

    Creator:
    Lamb, Michael J.
    Abstract:
    Watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai var. Crimson Sweet) was seeded in a commercial peat mix in multicell containers (72 cells-tray⁻¹, 40 cm³-cell⁻¹) in July 1989 and April 1990. In 1989, the medium was amended with CaC0₃ at 10% w:v. In 1990, no CaC0₃ amendment was made. Watermelon seedling...

  • Nitrogen use and management in red raspberry

    Creator:
    Rempel, Hannah Gascho
    Abstract:
    The effects of ¹⁵N-labeled fertilizer applied to mature summer-bearing red raspberry (Rubus idaeus L.) plants were measured over two years. Four nitrogen (N) treatments were applied singularly at 0, 40, or 80 kg·ha⁻¹ of N in early spring (budbreak), or split with 40 kg·ha⁻¹ of N (unlabeled) applied at budbreak...

  • Nitrogen use in container-grown woody ornamentals

    Creator:
    Sandrock, David Ray, 1971-
    Abstract:
    Lasting, effective solutions to nitrogen (N) loss from container nurseries must address layers of complexity ranging in scale from whole system nursery management to gene expression. Group-based On-site Active Learning (GOAL) was developed to aid nursery managers and related stakeholders (e.g. neighbors, policy makers, regulating agencies, researchers) in developing a...

  • Nitrogen, defoliation and new growth in almond (Prunus dulcis (Mill) D.A. Webb) nursery plants

    Creator:
    Bi, Guihong
    Abstract:
    The relationships between nitrogen (N), defoliation, and plant growth in nursery plants were studied using almond {Prunus dulcis (Mill) D. A. Webb) trees. In several experiments the effects of N source and availability on tree growth, N uptake, N remobilization, and nonstructural carbohydrates (TNC) were investigated to determine the most...
