Econometric Analysis of the Economic Cost of Lethal Yellowing Disease (LYD) on Coconut (Cocos nucifera L.) Yield in LYD Epidemic Area of Nigeria: A Case Study of Nigerian Institute for Oil Palm Research (NIFOR)
Journal Title: Journal of Experimental Agriculture International - Year 2016, Vol 11, Issue 5
Abstract
Coconut is cultivated particularly in the Southern part of Nigeria mostly as economic crop. However, in recent years its production has been declining due to lethal yellowing disease (LYD). This poses a threat to coconut and its industry, and consequently to coconut growers in LYD epidemic zones. This study is aimed at ascertaining the economic cost of lethal yellowing disease on coconut (Cocos nucifera) yield in LYD epidemic zones in Nigeria. Data spanning 10 years, from 2000 to 2010 obtained from the records of Plant Breeding Division, Nigerian Institute for Oil Palm Research (NIFOR) Benin City, Edo State were used for this study. Ordinary least squares (OLS) method was employed. The software used for analysis was Eviews7. Results obtained from the regression of the data indicate that expected annual yield of diseased palms (EAYDP) and price per unit nut (PUN) are significant determinants of economic cost of coconut production in the area and that LYD is a major threat to coconut production. It is recommended that preventive and control measures should be taken to reduce the incidence of LYD in epidemic zones.
