The study investigated the factors influencing the involvement of farm families in non farm income generating activities. Multi — stage and stratified simple random sampling procedures were used to compose the sample. The sample was made up of seventy two (72) heads of rural farm families. Data were collected by use of structured interview schedule and Focus Group Discussion. Data were analysed by simple percentage, Chi square test, multiple regression and correlation There was a significant relationship between number of non farm income generating activities and demographic characteristics (R2 = 0.870). Farm size (t = -2.386; p = 0.020), level of education (t = -4.227; p = 0.00), and household size (t = 5.404; p = 0.00) were significant and constant predictors of number of non farm income generating activities engaged in by the farm families. A significant relationship was found between involvement in non farm income generating activities and soil degradation due to infertility (X2 = 23.66, p < 0.01) and oil spillage (X2 = 26.01, p < 0.01). The study established a linear relationship between number of income generating activities and demographic characteristics. Extension workers should take into cognisance all rural income generating activities engaged in by the farm families when embarking on services and programmes aimed at improving their welfare.
