Contract Farming Arrangements and Income Stability Among Tomato Growers in Kaduna State

Contract farming has been increasingly promoted in Nigeria as a mechanism to integrate smallholder and commercial farmers into structured value chains by providing assured markets, input credit, and technical support in exchange for committed output delivery. In Kaduna State, in the North West geopolitical zone, contract arrangements between tomato processors and tomato growers have emerged as part of efforts to develop a domestic supply base for canned tomato products. This study analyses the nature of contract farming arrangements and their effect on income stability among tomato growers in Kaduna State. A sample of 55 contracted tomato farmers and 30 non-contracted farmers was selected from Makarfi and Lere local government areas for comparative analysis. Data on contract terms, input support received, price guarantees, output delivery compliance, and seasonal income variability were collected through structured interviews. Propensity score matching was applied to reduce selection bias in the comparison. Results indicate that contracted farmers received inputs on credit averaging N45,000 per hectare, eliminating upfront capital constraints. Income variability across seasons was 32 percent lower among contracted farmers, attributable to price guarantee floors that prevented the worst market price crashes. However, 28 percent of contracted farmers reported side-selling at least part of their output due to delayed processor payments. Contract terms were perceived as unfair by a significant proportion of respondents regarding price renegotiation clauses. The study recommends strengthening contract transparency and farmer bargaining capacity through model contract templates and farmer association engagement in Kaduna State's agro-processing sector.
