Results also showed that majority of those who consumed the vegetable (71.63 and 87.19% of the rural and urban households, respectively) obtained their supplies through purchases. The average cost of the vegetables per household per week and per year were 94.13 and 4,894 Nigerian Naira for rural households and N102.99 and N 5,355.48 for urban households. The price estimates given by those categories of households who planted their own vegetables showed that they were saving N128.08 and N6,660 in the rural and N66.70 and N 3,488.48 in the urban communities per week and per year. Also, the market surveys showed that an average of nine and 13 persons representing in each case 8.21% of all vegetable sellers were involved in marketing of G. africanum in the rural
