Measurement of Technical Efficiency of Irrigated and Rainfed Onion Farms in Kano State of Nigeria

Abstract

This study estimated technical efficiency of irrigated and rain-fed onion production in Kano State of Nigeria, and was carried out in six selected Local Government Areas (LGAs) of the state. A multi-stage sampling technique was used to select 217 onion farmers involved in both irrigated and Rain-fed production systems. The study made use of primary data, collected through structured questionnaires. Descriptive statistics and stochastic frontier model were used to analyse the data. Generally, young literate married men with 5 household size and14 years of farming experience were involved in onion farming. The Maximum Likelihood Estimate (MLE) for production frontier shows that the variable inputs (farm size, hired and family labour, seeds and fertilizers) have positive coefficients and were significant at 5% level. This implied positive effect on onion yields under both production systems, while agro-chemical was negative under rain-fed. The mean technical efficiency was higher for irrigated onion farmers than rain-fed farmers indicating that onion production was technically more efficient under irrigation system of production than rain-fed system of production. Educations, experience, membership of cooperative, access to credit are socio-economic variables that reduce technical inefficiency in both systems of production. The following recommendations were made; contract farming, introduction of hybrid seeds, formation of cooperative societies and private partnership participation with government should be encouraged to boost irrigated onion production not only for home and local industry but also for export to other countries of the world.
