This study evaluated the efficiency of diversification versus specialization of vegetable-based farms in the West region of Cameroon. The study employed the use of a questionnaire to obtain information from 70 specialized and 54 diversified farmers randomly selected from three purposively selected localities in the West region. The one-step stochastic frontier approach with a Cobb-Douglas model specification was used in analysis. Data was analyzed using the computer program, STATA version 12.0. Findings revealed that majority (71.8%) of vegetable farmers are males, with an average age of 30 years and 73.4% had attained at least a primary education. Results of the stochastic frontier analysis revealed the mean technical efficiency of vegetable farmers to be 0.863. Mean technical efficiency scores for specialized and diversified farmers were found to be 0.867 and 0.858 respectively. However, the results of a standard t-test concluded that technical efficiency is invariant of cropping system. The main sources of inefficiency were identified to be farm size, education, credit and membership to a mutual aid group, while age, sex and access to extension information and services were found to enhance technical efficiency. The study therefore recommends extension services to be reinforced on farmers who receive loan and on those who belong to mutual aid groups, in a bid to increase technical efficiency.
