This study was designed to measure technical efficiency and identify its determinants in crop
production in Lafia Local government Area of Nasarawa State of Nigeria using a stochastic frontier
production model. Double stage random sampling technique was used to select 100 crop farmers
from which input-output data were collected based on 2005 cropping season. The results revealed
that sixty five percent (65%) of the farmers were within the age range of 31-50 years and 67% had
farm size ranging from 2-4 hectares. The technical efficiency of crop production range from 32.7%
to 89.4% with mean of 69.6%. Farm size and fertilizer were the major inputs that are associated with
the variation in crop output. The significant socio economic variables that accounted for the
observed variations in technical efficiency among crop farmers were age, gender, marital status,
household size, other occupation and land ownership. It is therefore recommended that a land
redistribution policy that will increase the farm size of the farmers should be initiated. Fertilizer
supply at subsidized rate to farmers in the area should be encouraged.
