An Investigation of Productivity Growth, Technical Progress and Efficiency Change in Nigerian Cotton Agriculture

Samuel Binuomote

Abstract


This study investigates the Total Factor Productivity (TFP) growth in Nigerian cotton and its decomposition to efficiency change and technological progress using the data envelopment analysis (DEA) approach. The present study uses data of 10 states over the period 1994 - 2005, calculations are based on panel data of major cotton producers in the nation collected from Nigeria Bureau of Statistics database. The data includes cotton output and four input variables comprising of land, area, labor, seed and capital. It was found that, during that period, total factor productivity has experienced a negative evolution in sampled states. This poor performance of the cotton production was due to poor progress in technical efficiency and technical progress. This study also highlights the fact that technical change has been the main constraint of achievement of high levels of total factor productivity during the reference period in Nigeria. The results show that there is potential for efficiency and technical improvements in cotton production in Nigeria if there is sustained productivity growth.
