SPATIAL IMPACT AND VARIATION OF FARM INCOME AMONG FARMERS IN ABIA STATE, NIGERIA
The significant influence of location on agricultural production has not been largely investigated. Due to the
paucity of empirical evidence of this influence, this study was designed to analyze the impact of spatial difference
on farm income among farmers in Abia State, Nigeria. A multi stage randomized sampling procedure was used to
select 80 farming households in two Agricultural Zones (Ohafia and Umuahia) in the State. Primary data were
collected by the use of the cost route approach with the aid of a well-structured questionnaire. Data were analyzed
using descriptive statistics, multiple regression and Chows' test. The results showed that the income of farmers in
Ohafia Agricultural Zone (OAZ) was higher than the income of farmers in Umuahia Agricultural Zone (UAZ).
Chow's test showed that the difference in income of the farmers was due to spatial difference between the two
zones. The results of the multiple regression also showed that education, labour availability and farm size were
significant drivers of farm income. A consideration of spatial differences in the environment of agricultural
production is important in the design, development and introduction of improved agricultural technologies and in
the planning and implementation of agricultural development programmes.
