  • Nitrogen dynamics in field grown comice pears

    Creator:
    Sanchez, Enrique E.
    Abstract:
    The dynamics of N was studied in field grown Comice/Provence quince BA29 pears in Medford, Oregon. Total tree biomass, N content, and ¹⁵N evaluations suggest that young pears require little N (48 kg N ha⁻¹ yr⁻¹). About 45% of total tree N present in dormant trees was remobilized into new...

  • Diagnostic approaches to evaluate nutrient status, partitioning, mineral dynamics, and relationships with yield and fruit quality of 'Valencia' orange trees

    Creator:
    Tami, Mohamed
    Abstract:
    Five nutritional aspects of 'Valencia' orange production in Agadir, Morocco during 1989-1991 were evaluated: 1) the effect of N and K on yield and fruit quality, 2) leaf sampling time and diagnostic approaches to optimize mineral nutrition, 3) mass and mineral partitioning within individual trees, 4) K-Rb relationships, and 5)...

  • 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...
