This study was designed to quantitatively determine the impact of Fadama II Project on the farm income
of tomato producers by utilizing primary data from tomato farmers in Bosso and Mokwa Local
Government Areas of Niger State for the year 2009. Production function analysis and Chow’s analysis
of covariance confirmed significant differences in production functions, heterogeneity in slopes and
intercepts and factor bias was observed on the production functions of participating and nonparticipating
farmers respectively. The project exerted a positive significant impact on the incomes of
the farmers. The study recommends improvement in irrigation performance, introduction of improved
varieties of tomato, strengthening relevant research and extension as well as formation of organized
farmer associations.
