This study evaluated moisture, ash and color in sweetpotato varieties: [Beauregard (BEAU), Porto Rican (PR) and Nugget (N)]. The experimental design was a randomized-complete-block with four replications, four treatments and three varieties. Treatments included control without fertilizer (CTRL), broiler litter (BL), Crimson-clover (CLOV) and NPK fertilizers. BEAU had the lowest L values, and was darker in color than PR and N. Mean moisture content for the four groups was 60.1± 6.7% CTRL; 54.7± 7.9% BL; 60.9±5.1% CLOV and 63.2± 6.1% for NPK. Mean ash contents were: 2.5± 0.1; 3.5± 0.3 and 2.1± 0.02 for BEA, PR and N, respectively.
