Research Project: ORGANIC AND REDUCED INPUT FRESH MARKET SPECIALTY CROP PRODUCTION SYSTEMS FOR THE SOUTHERN GREAT PLAINS
2012 Annual Report


1a.Objectives (from AD-416):
Field trials with vegetable and non-vegetable crops will identify profitable crop combinations. Over the next 4 years the focus will be on the following objectives 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 integrated production systems for vegetable and non-vegetable crops. Sub-objective 1.B. Determine effects of components in rotations on input costs, productivity, and whole-system profitability. Objective 2: Develop weed 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 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, 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 research projects and expected end products will provide specific cost comparisons and decision making tools for production systems.


3.Progress Report:
This project began 10/19/10 and terminated 1/12/12, due to FY12 Appropriation direction for Unit closure. During the life of the project, all objectives were addressed. Development of production systems to improve yield of vegetables in the Southern Plains and on control of weeds in vegetable and non-vegetable crop experiments were initiated in the 2011 growing season. Data were collected, compiled, and entered into databases. No research was conducted during FY12; all efforts were directed toward the efficient finalization of this project.
