2013 Annual Report
b) Evaluate seedling emergence.
c) Hand weed organic plots as needed; control weeds in conventional trials.
d) Evaluate top size of each entry at one month, 3 months, and harvest.
e) Harvest crop and provide root samples to PI's lab.
Stand and vigor counts, as well as early and mid-season top heights and widths, showed significant variation in the seedling vigor and early season growth of the various lines included in the trial. For the first planting, 35 day and 55 day stand evaluations occurred on June 21, 2012 and July 11, 2013. For the second planting, these evaluations occurred on August 3, 2012 and August 22, 2012. Fungal disease and insect pressure also varied between the trial entries.
Harvest for the first planting of carrots occurred on September 3, 2012 and harvest for the second planting occurred on October 16, 2012. While a complete evaluation was performed on the first harvest, only targeted entries were evaluated on the second harvest.
The primary outreach event for the project occurred on August 13, 2012. With participation from the Organic Seed Alliance (OSA), the University of Wisconsin organized an organic breeding workshop, at which the Carrot Improvement for Organic Agriculture (CIOA) project was highlighted and the fields toured.
This research relates to the objective "Develop carrot breeding stocks for production in organic agriculture systems with improved nutritional value, trial carrots in diverse growing locations, and release germplasm to the seed industry. Grow carrot trials under conventional and organic practices in Wisconsin" by growing carrots under conventional and organic practices and by evaluating growth in these conditions.
