Cashew is an emerging agricultural export crop in Nigeria. However, significant export earnings have not been recorded in recent years from cashew exports. The study investigated the determinants of the cashew nuts export supply in Nigeria between 1980 and 2019. Secondary data extracted from the publications of the Food and Agriculture Organization statistical database (FAOSTAT), the National Bureau of Statistics (NBS), and the Central Bank of Nigeria (CBN). Means, percentages, and coefficient of variations were the descriptive statistical tools used, while Augment Dickey-Fuller (ADF), Johansen co-integration and vector error correction model (VECM) were the inferential statistical tools employed in the study. ADF and Johansen's results show that the variables of the model were stationary after the first difference and co-integrated. Domestic production export supply and earnings fluctuated over the period of the study with a mean of 247,560.70 tonnes, 33,010.22 tonnes, and ₦47,462.43 million respectively. The average annual growth rate of cashew nuts production, export supply, and export earnings was 197.98 percent and 565.79 percent respectively VECM result reveals that domestic cashew nut production and exchange rate have asymmetric influence and cashew nuts export supply in the short run, while agricultural land area, cashew nuts production and inflation rate negatively influence cashew nuts export supply in the short run, but exchange rate positively influences cashew nut export supply in the long run. It is concluded that agricultural land area domestic production, of cashew nuts, exchange, and inflation rate significantly influence the export supply of cashew nuts in the study area. Thus, significant policy reform on the production of cashew nuts, exchange, and the inflation rate would improve exports supply of cashew nuts significantly.
