Yam storage methods in Nigeria were studied, evaluated and compared. Among the storage methods studied, evaluated and compared include designed barn, traditional barn, house and pit storages. The parameters taken to assess their performance were tuber weight loss, rotting, sprouting and pest infestation after fourteen (14) weeks of storage. Designed barn storage methods with weight loss of 29.6996kg was compared to other storage methods with weight loss value of 58.199kg (pit storage) 46.800kg (house storage) and 47.8002kg (traditional storage) from the big tuber sizes (1.5 – 1.8kg). From the small tuber size (0.7 – 0.9kg), the weight loss recorded from each storage methods included, designed barn 24.2004kg; pit storage44.8994kg; house storage 43.4994kg and traditional barn 46.6004kg. Rotting was recorded nil from designed barn for both big tubers and small tubers and 10 tubers each were recorded from pit house and traditional barn for big tubers, pit storage recorded 20 tubers and others recorded nil for small tubers. Records on sprouting indicated the following numbers of tubers from each storage methods. From the big tubers set, designed barn had 20 tubers sprouting within 14 weeks duration but pit had 30 tubers while house storage had 20 tubers and traditional barn 30 tubers sprouted. From small sized tubers, records on sprouting indicated the following, designed barn nil, pit storage 80 tubers, house storage 40 tubers and traditional 60 tubers. Data collected from each storage facility were statistically analyzed and compared using Completely Randomized Design (CRD), ANOVA, standard deviation and LSD). Designed storage structure is recommended for use by yam farmers to alleviate their losses after harvest and to help farmers prolong the life span of their produce for future use as food, planting materials, industrial use and commercial uses.
