On-Farm Assessment of Melon and Cucumber Feedstocks for Downy Mildew and Bacterial Wilt

In this project I will assess resistance to both Bacterial Wilt and Cucurbit Downy Mildew among selected cucumber and muskmelon seedstocks, and move forward with an ongoing project to develop a pickling cucumber that is resistant to both diseases.

Corn Earworm Management: A Survey of Organic Sweet Corn Growers

The objectives of this project are to attain information about the corn earworm management strategies of organic sweet corn growers. This information will be used to achieve two outcomes: creation of an extension publication about corn earworm management strategies, aimed at organic farmers, and collection of data that will inform longer-term efforts of developing earworm-resistant sweet corn cultivars for organic farmers.

Evaluation of Organic Strawberry Transplants for Organic Strawberry Production

Conventional strawberry nurseries that fumigate soils with methyl bromide and other synthetic chemicals prior to propagation are currently the main source of transplants for both conventional and organic production systems. While many organic strawberry growers have expressed dissatisfaction with having to use conventional transplants, organic transplants simply are not commercially available. In part, commercial availability of organic transplants has been limited due to a lack of tested varieties as well as a lack of supply during the traditional planting season.

Development of Wheat Varieties For Organic Farmers

From the mid-1950’s on, most wheat in the U.S. has been grown in and bred for high-input, traditional agricultural conditions.  These conditions include the common use of artificial fertilizers and chemical herbicides and fungicides, practices that are not allowed under current certified organic standards.  We believe that traits specifically adapted to and useful for organic wheat production have been lost from the gene pool of modern wheat varieties due to the intensive chemical management common in current wheat-breeding programs.

Developing open-pollinated corn varieties for organic farmers

The purpose of this project has been to develop and evaluate our open-pollinated corn varieties for organic farmers. Our major efforts have been to increase the qualitative value and future marketability of these populations and also to increase their genetic diversity and agronomic value. This year we continued to breed white, yellow, red, and blue field corn varieties towards fitting niche markets that would give farmers that used this corn economic benefits.

Targeted mowing as a weed management method increasing allelopathy in rye (Secaule cereale L.)

Winter rye (Secale cereale L.) is an outstanding cover crop in its suppression of early season weeds. This suppression has been largely attributed to allelopathy; ryeís allelochemicals inhibit weed germination and growth. However, its lack of suppression of late season weeds and its inconsistent results between years and regions hinder the use of rye as a cover crop. This study, which is Part I of a 2-year project, explores a management method that may be used to increase weed suppression of rye by manipulating its allelopathic activity.

Participatory Screening of Broccoli Varieties for Summer Production in Organic Systems in Western North Carolina—Year 3: Phase II--On-farm Trials

There is high demand for organic broccoli in the Southeast, as shown in a 2013 market survey by Carolina Farm Stewardship Association, which revealed that broccoli is one of the top organic produce items in short supply. Broccoli can be produced most anywhere in the spring and fall, but summer production is limited to cooler growing areas.

Organic Food Barley: Developing Nutritious and Delicious Varieties for the Pacific Northwest

Researchers from Washington State University have been breeding and selecting hulless food barley types for almost a decade with the goal of releasing high yielding, nutritious barley varieties in this novel market class.  Now in the final stages of this project, they will work to identify the advanced breeding lines most adapted to organic farmers in Washington State and Northern Idaho.  In addition, the researcher
