Abstract: This paper evaluates the impact of adopting Integrated Striga Management (ISM) technologies on maize productivity among rural households of northern Nigeria. The study utilizes cross-sectional data collected in 2014 from a randomly selected 643 households. A treatment effect regression model was used to estimate the causal impact of ISM technology adoption on farm productivity. The results revealed that adoption of ISM technology has a significant positive impact on maize yield per hectare. This confirms the potential role of ISM technology adoption in the Striga infested areas in improving rural household productivity and its ability to withstand production risk. An analysis of the determinants of adoption suggested farmer age, cooperative membership, past participation in on-farm trials, access to cash remittances, access to fertilizer, access to improved seeds and yield perception as the key determinants of ISM technology adoption. Results from the treatment effect model indicate that adoption of ISM technologies has a positive effect on farm productivity, with adopters on average achieving a 47% increase in maize yield per ha above that of non-adopters. Policy implications for promoting ISM technology adoption and farm productivity are discussed.
