Abstract: A field experiment was carried out to assess the effects of 3 seed tuber sizes (< 5, 5 ≤ 15 and > 15 g) and 4 levels (0, 100, 200 and 300 kg ha-1) of NPK fertilizer on some tuber yield components of Coleus potato (Solenostemon rotundifolius). Factorial combinations of the 3 seed tuber sizes and the 4 NPK application rates formed 12 treatments evaluated. The treatments were fitted into a Randomized Complete Block Design (RCBD) with three replications. Data were collected on number of healthy and rotten tubers, fresh weight of tubers, length of tubers and girth of tubers. The measured variables differed significantly (P ≤ 0.05) depending on seed tuber size. The smallest seed tuber (< 5 g) recorded the highest number of healthy tubers but was similar to the other seed tubers. Total tuber fresh weight from < 5 g seed tubers (839.1 g) was significantly (p ≤ 0.05) heavier by 51.2 % than that of > 15 g seed tubers (554.8 g). Application of 300 kg NPK ha-1 increased the number of rotten tubers (51) relative to the control treatment (28). The 0 and 100 kg NPK ha-1 treatments produced heavier tubers than the 200 and 300 kg NPK ha-1 treatments. These results signify that the smallest seed tuber (< 5 g) enhanced tuber yield better than the other seed tubers. It is evident that Coleus potato could yield well without NPK fertilization when soil nitrogen is high (i.e. > 0.2 %).
