Productivity Determinants of Potato in Nigeria: An Autoregressive Distributed Lag Model Approach

This study examined the productivity determinants of potato in Nigeria. The data for this study were extracted from secondary sources for a period of 1961-2016. The Autoregressive Distributed Lag (ARDL) model was adopted. The findings revealed that variables such as capital, land, fertilizer and prices were significant both in the long-run and short-run while rainfall and temperature were insignificant in the short-run. The study recommends among others that access to capital by the potato farmers should be increased by making more capital available for loans and grants at a reduced interest rate and that the land tenure system in operation should be made flexible to enable potato farmers access more land to enable mechanization and increased output.
