Abstract:
The study was conducted at Nguroje, Mambilla Plateau to evaluate twelve potato genotypes for their growth, yield and internal characteristics during the two growing seasons of 2021/2022. The experiment was carried out using randomized complete block design with three replications. The results of the combined analysis of variance revealed highly significant differences (p≤0.01) among the genotypes for all the characters studied except for percentage marketable tuber size. The mean performance showed that Caruso performed better that the other varieties in leaf width, percentage marketable tuber size, weight of tubers per plant, weight of tubers per plot, and total tuber yield per hectare, closely followed by Superior variety with percentage marketable size, weight of tuber per plant, weight of tubers per plot, and total tuber yield per hectare respectively. Bertita exhibited highest values in number for tubers per plant, number of tubers per plot and starch content. Higher yielding potentials exerted by Caruso, Superior and Bertita varieties indicates a good adaptation to the prevailing environmental conditions and hence recommended for the study area.
