Abstract Agricultural Growth Program is a multifaceted program that has been under implementation since 2011 in the study area, which is aimed at mitigating the agricultural bottlenecks of smallholder agriculture through provision of different services and then increasing agricultural production. The current study focuses on the contribution of the Agricultural Growth Program to agricultural production income in the case of Ankesha Guagusa woreda. It employed a combined research approach; quantitative and qualitative. The study was based on survey of 114 Agricultural Growth Program user and 79 non-user representative farm households systematically selected from a total of 3863 households found on three kebeles of the study area. To achieve the objectives, household questionnaire surveys, key informant interviews, observations and focus group discussions were conducted to collect data at household level. Data were analyzed using descriptive statistics, independent t-test, chi-square test and the multiple regression model. Improving the extension advisory service, increasing the sufficiency and timely availability of agricultural inputs, improving the accessibility of irrigation service, bridging the skill gaps of smallholder farmers and supporting the formation of farmer groups with common interests are the major services of the program in the study area. The study revealed that the mean annual income for Agricultural Growth Program users and non-users were Ethiopian Birr 46,339.75 and 20,098.95, respectively. Annual household incomes of Agricultural Growth Program users were higher than the incomes of non-user households, and extent of utilizing these services by the target beneficiaries of the program; the better use of a service, the more to utilize the same. The study also made clear that a host of constraints, most of which are implementer related, hinders the maximum utilization of Agricultural Growth Program services by beneficiaries. Apart from these, the survey result confirms that the program implementation is carried out by different organizations without proper coordination, poor monitoring and evaluation, inadequate stakeholder participation and low sense of program ownership. Finally, the study recommended that the program needs to work on rehabilitation and upgrading of the existing canals and there should be a strong monitoring and follow up while constructing irrigation schemes, the program coordinators need to establish a strong coordination among stakeholders and there should be clear criteria for the selection of Common Interest Group members that help members to have a common interest Key Words: Agricultural growth program, service utilization, program implementers
