This work was conducted in the Department of Crop Production and Horticulture, Modibbo Adama University Yola, and it was designed to determine the proximate composition as well as vitamin C component for pineapple peels and watermelon The results revealed higher carbohydrates, fiber and vitamin C content with 10.16 ± 0.226 %, 2.15 ± 0.0707 %, and 17.42 ± 0.260 mg/100g, respectively in pineapple, while watermelon showed higher protein content of 1.775 ± 0.0354 %. The average amount of wastes was 522g and 1600g, with a percentage range of 17.3-24.3 % and 45.5-54.6 % in pineapple and watermelon respectively. There was a significant difference between the means of the amount of pineapple peels and pulp and watermelon rind and pulp with p values of <0.001 and 0.02 respectively. The pineapple peels were used to enrich Roselle calyx drink (zobo) and all the formulations P1-P3 were recommended for zobo enrichment. More research was recommended on the use of watermelon peels
