Analysis of Trend, Growth, and Instability Index in Output, Harvested Area, and Yield of Oil Palm Fruit in Nigeria

Abstract

The research examined the trend, growth rate, and instability index related to the output, harvested area, and yield of oil palm fruit in Nigeria. Utilizing secondary data sourced from the Food and Agricultural Organization (FAO) covering the period from 1961 to 2022, the study revealed inconsistent patterns in the trend of output, harvested area, and yield of oil palm fruit across the specified timeframes. The compound growth rates identified were 1.11% for output, 1.03% for harvested area, and 0.08% for yield. The Cuddy-Della Valle instability index (CDI) and the Coppock Instability Index (COI) were calculated at 13.87 and 46.57 for output, 13.87 and 46.02 for harvested area, and 2.52 and 37.88 for yield, respectively. These instability indices were relatively low, indicating limited activity within the oil palm fruit sub-sector in Nigeria. A decomposition analysis of the total effect of the output showed that the area effect accounted for 94.20%, the yield effect for 3.19%, and the interactive effect for 2.61%. The findings indicate that the area effect is the predominant factor driving the growth of oil palm fruit production in Nigeria. Consequently, it is recommended that various programs such as; small grower schemes, oil palm farmers’ cooperatives, and off-takers scheme be implemented within the sub-sector to stimulate increased activities, production, and yield. Also, the oil palm fruit farmers should be provided with quality seeds and financial resources in addition to broadening research efforts aimed at developing high-yield varieties.
