A survey was conducted among farmers in Mangu Local Government Area in 2006 on postharvest spoilage of potato (solanum tuberosum L.). Emphasis was on factors which predispose potato to spoilage and control measures adopted. Questionnaires (150) were randomly administered to individual farmers selected from six out of nine potato producing Districts in the study area. Properly filled and returned questionnaires were 145. Data were analyzed using descriptive statistics and regression analysis. Slightly over one third (36.55%) of the respondents did not destroy potato haulms before harvest while about two third of them (63.45%) destroyed the haulms one to three weeks earlier. Almost half of the respondents (45.66%) stored between 1-10 bags while 93.79% of the respondents stored Irish potato in a general store only 5.52% of them share the bedroom with potato. One respondent used pit (trenches) for potato storage. In order to reduce deterioration of potato tubers, 82.76% of the respondents frequently checked their produce under storage to remove infected tubers. Almost 9% sold their produce immediately after harvest to avoid spoilage in the store and 8.28% treat with chemicals. Regression analyses revealed that the time of harvesting after haulm destruction and type of storage structure used by the farmers have positive significant (P<0.05) effect on deterioration of Irish potato and number of bags stored also significantly (P<0.01) affect deterioration of the produce. The control measures applied by farmers have negative significant (P<0.05) effect on deterioration of the total produce. The implication of the result is that farmers can reduce deterioration of their crops by decreasing the quantity of bags stored in a place at a time and increasing the control measures adopted. Therefore, a store room should be built solely for storing Irish potato by farmers.
