Vegetables

Diverse vegetable production systems in Washington State range from large-scale, processed vegetable production in Central Washington (e.g., potatoes for french fries) to diversified fresh-market vegetable production, to vegetable seed production. These systems range from traditional conventional production to integrated to organic and are significant for local, regional, national, global and processed markets. Each of these production systems as well as sub-regions of Washington state have unique challenges to sustainable production. CSANR has supported research on a variety of vegetable production issues including fertility, nutrition, crop protection, diversification and soil quality.

  • Management to Reduce N2O Emissions in Organic Vegetable Production Systems

    Cogger, C., A. Fortuna, D. Collins. Feb 27, 2014. The second of a two-part webinar series on Greenhouse Gas Emissions and Soil Quality in Long-term Integrated and Transitional Reduced Tillage Organic Systems.

    This is the focus of our current research. How do different organic vegetable production systems affect N2O emissions, and how do other outcomes of those systems affect their potential for adoption?

    • Systems include full tillage with high-carbon amendment (compost), full tillage with low carbon amendment (broiler litter), pasture-vegetable rotation, and reduced tillage cover crop mulch.
    • Measurements include N2O and CO2 emissions, soil N, microbial ecology focused on denitrification organisms, crop yield, and soil quality. Measurements are focused on key times during the season, including amendment application and tillage, irrigation, and freeze-thaw.

    Intended audience is other researchers, and interested extension faculty and farmers.

  • Soil Testing: A Guide for Farms with Diverse Vegetable Crops

    Collins, D. 2012. Washington State University Extension. EM050E.

  • WSU Vegetable Research and Extension

    Vegetable crop production and alternative crop development such as edamame, wasabi, bamboo, and organic seed production. Work is targeted for both small-scale and large commercial growers, with emphasis on organic production. Links include new fact sheets and information on grafted vegetables http://vegetables.wsu.edu/graftingVegetables.html .

  • Can we grow more nutritious fruits and vegetables using organic farming methods?

    (Recorded Webinar) Andrews, Preston. WSU. 2011.

  • Organic Farming Systems

    In 2003 an organic vegetable production systems experiment was established on organically certified research land at WSU Puyallup. The experiment compares 12 organic management systems, including three cover cropping systems, 2 tillage treatments, and 2 amendment types, arranged in a split-split plot design.
