Sweet potato harvest

Ajay Nair

Our sweet potato harvest took place on October 17th, 2013, three weeks later than 2012. Overall the crop grew well. Slips were planted on June 7, 2013 on black plastic mulch. The mulch helps increase soil temperature and suppress weeds. Weeding was minimal, only two times, until the canopy closure. The crop was affected by Japanese beetles but the plants came out of it gradually.

We conducted two experiments this year, one identifying suitable cultivars for Iowa growing conditions and the other investigating appropriate spacing of sweet potatoes. Data will be soon analyzed and made available through ISU Research Farm Progress Reports and at http://www.extension.iastate.edu/vegetablelab/content/publications-and-reports
