  • Refining nitrogen management for organic broccoli production

    Creator:
    Sullivan, Dan M., Peachey, Ed, and Donaldson, Andrew
    Abstract:
    Specialty organic fertilizers used in organic vegetable production are expensive. So, from environmental and economic perspectives, growers want to maximize nitrogen (N) fertilizer use efficiency by the crop. This research was conducted to (1) determine sufficient N fertilizer rates for organic broccoli, (2) evaluate the efficacy of a specialty organic...

  • Improving nitrogen management with cover crops in organic broccoli production

    Creator:
    Garrett, Amy
    Abstract:
    Legume cover crops can serve as important sources of nitrogen (N) in sustainable agriculture and can be economically beneficial when fertilizer inputs are reduced without a yield reduction. Synchronizing N mineralization from organic materials with the needs of the subsequent crop is a challenge for organic growers. Predicting plant available...

  • Breeding an open pollinated broccoli for organic production systems using participatory methods

    Creator:
    McKenzie, Laurie R.
    Abstract:
    Organic agriculture is an important and growing sector of U.S. and world food production. Consumers are increasingly aware of and interested in the production practices and impacts associated with agriculture and as such, are showing a preference for sustainably produced, raised, and harvested foods. In order to continue to meet...
