Evaluation of Sweetpotatoes Grown with and without Ryegrass Cover Crop 2007-01-3048

This study compared nutritional and physical properties of Beauregard sweetpotatoes grown without, A2, and with, A4, cover crop (ryegrass). Moisture, β-carotene, ash, ascorbic acid and protein contents, color, and texture were determined. A2 Sweetpotatoes had moisture contents of 75.2±1.69% verse 76.3±1.78% for A4. Ash was about 0.7% for all the sweetpotatoes. Average β-carotene for A2 was 35300 µg/100 g while that for A4 was 36100 µg/100g. Ascorbic acid for A2 was 13.6±4.02 versus 17.5±4.12 mg/100 g for A4. No significant nutritional and physical differences were found between A2 and A4 sweetpotatoes.
