Determinants Affecting Input-Output Relationship in Yam Production in Ikom Agricultural Zone of Cross River State, Nigeria


The study was carried out in the Ikom Agricultural Zone of Cross River State, Nigeria, to examine the relationship between the inputs and outputs of yam. A multistage sampling technique was used for the study. A total of 240 respondents were randomly selected from thirteen villages. Questionnaires were administered to the respondents by the interview method. The data collected were analyzed using regression analysis from STATA v17. The double-log result showed that inputs that significantly influenced yam output in the study area were quantity of fertilizer, seedlings, labour, access to credit, and farm size, at 1% and 5%, respectively. It is recommended that yam farmers increase their farm sizes in cultivation, fertilizer usage, and yam seedlings to increase yam output.
