Research Project: ORGANIC AND REDUCED INPUT FRESH MARKET SPECIALTY CROP PRODUCTION SYSTEMS FOR THE SOUTHERN GREAT PLAINS
2009 Annual Report


1a.Objectives (from AD-416)
Field trials with vegetable and biofuels crops will identify profitable production combinations. Over the next 5 years we will focus on the following objective and sub-objectives: Objective 1: Develop management practices and production systems for South Central region farms to help small- and medium-sized producers diversify farm income and increase profitability. Sub-objective 1.A. Develop rotations to integrate biofuel feedstocks as components with specialty vegetable crops in production systems. Sub-objective 1.B. Determine effects of different crop components in rotations on input costs, productivity, and whole-system profitability. Objective 2: Develop soil-borne and post-harvest disease suppressive practices applicable to organic and reduced input specialty vegetable crop production systems.


1b.Approach (from AD-416)
All projects will be conducted on a Bernow fine-loamy, siliceous, themic, Glossic Paleudaulf soil in Lane, OK, at the South Central Agricultural Research Laboratory. The proposed research will address efficacy of rotations including economic realities of production, effects of fertilizer management within rotations, effects of weed control within rotations, and specific questions concerning applicability of organic herbicides in biofuel feedstock production, and use of biofumigation as it affects establishment of crops. Concerns from stakeholders regarding weed control in particular vegetable crops will also be addressed. The proposed research projects and expected end products will provide specific cost comparisons and decision making tools for production systems.


3.Progress Report
New project replacing 6222-21220-002-00D, Yield and Quality of Vegetable Crops in Conventional and Organic Production Systems. The experiments scheduled to be initiated were established. Data from first-year experiments are being compiled and entered into databases.


5.Significant Activities that Support Special Target Populations
1. Surplus produce from vegetable field plots distributed to local food banks and similar operations through the USDA Gleaners program.

2. Provided seed, transplants, soil preparation and some field maintenance to establish a Community Garden in cooperation with the Choctaw Nation and Oklahoma State University.

3. Mentored a female, Hispanic, graduate student through MentorNet.

4. Mentored a male, Native American, student as a summer helper.

5. Mentored two female, Hispanic, students in science fair projects.

6. Classroom visits to 5 local schools with significant numbers of Native American students.
