Goals / Objectives
The objective of this cooperative research project is to gather scientific data on nutrient and phytonutrient content of organically produced vegetable crops.

Project Methods
Under the direction of ARS personnel, student interns will evaluate tomato, onion, and pepper for response to organic production methods, and will determine carotenoids, vitamin C, and other compounds in vegetables by spectrophotometric and high performance liquid chromatography methods.

Progress 09/01/07 to 08/31/09

Outputs
Progress Report Objectives (from AD-416) The objective of this cooperative research project is to gather scientific data on nutrient and phytonutrient content of organically produced vegetable crops. Approach (from AD-416) Under the direction of ARS personnel, student interns will evaluate tomato, onion, and pepper for response to organic production methods, and will determine carotenoids, vitamin C, and other compounds in vegetables by spectrophotometric and high performance liquid chromatography methods. Significant Activities that Support Special Target Populations The research conducted in cooperation with Southeastern Oklahoma State University analyzed organically produced tomato, onion, cantaloupe, and strawberry for phytonutrient content. Crops were harvested and tested for vitamin C and carotenoid contents using spectrophotometric and HPLC methods. The experiments determined phytonutrient potentials under organic versus conventional production methods. Student interns were shown laboratory techniques and tutored on scientific methods and poster presentation was given. The ADODR meets with the university coordinator at least semiannually by phone or site visit.
