THE PROBLEMS AND PROSPECTS OF COCOYAM PRODUCTION IN OVIA NORTH EAST LOCAL GOVERNMENT AREA OF EDO STATE, NIGERIA

Abstract

Cocoyam production remains an important component of food security, rural livelihood development, and income generation among farming households in Nigeria. Despite its nutritional and economic importance, cocoyam cultivation has experienced a gradual decline due to several production-related constraints such as poor access to improved planting materials, declining soil fertility, climate variability, pest and disease infestation, inadequate extension services, and limited access to agricultural credit facilities. This study examines the problems and prospects of cocoyam production in Ovia North East Local Government Area of Edo State, Nigeria. The study specifically evaluates the socio-economic characteristics of cocoyam farmers, identifies the major constraints affecting cocoyam production, and explores the opportunities for improving cocoyam productivity and commercialization in the study area. A descriptive survey research design was adopted, while primary data were collected through structured questionnaires administered to selected cocoyam farmers. Data were analyzed using descriptive statistics such as frequency distribution, percentages, and mean scores. Findings revealed that cocoyam farming contributes significantly to household food supply and income generation; however, productivity is constrained by inadequate finance, poor storage facilities, limited access to improved varieties, high cost of labour, and environmental challenges. The study further identified increasing market demand, improved agricultural technologies, and government intervention programmes as major prospects for the expansion of cocoyam production. The study recommends improved extension services, access to credit facilities, provision of improved cocoyam varieties, and increased investment in rural agricultural infrastructure to enhance sustainable cocoyam production in the area.

CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Agriculture remains one of the most important sectors of the Nigerian economy because of its contribution to food production, employment generation, poverty reduction, and rural development. Root and tuber crops occupy a strategic position in Nigeria’s agricultural system due to their adaptability to diverse ecological conditions and their importance in household nutrition. Among these crops, cocoyam plays a significant role in ensuring food security and income generation among rural farming households.

Cocoyam belongs to the family Araceae and is commonly classified into two major genera: Colocasia spp. and Xanthosoma spp. It is widely cultivated in tropical and subtropical regions, particularly in West Africa, Southeast Asia, and parts of Latin America. Nigeria is recognized as one of the leading producers of cocoyam globally, with production concentrated mainly in the southern and southeastern regions of the country (FAO, 2022).

Cocoyam serves multiple economic and nutritional purposes. The corms and cormels are rich in carbohydrates and minerals, while the leaves contain appreciable amounts of vitamins and dietary fibre. The crop can be consumed in several forms including boiled, roasted, fried, pounded, or processed into flour and chips. Cocoyam leaves are also used as vegetables in soup preparation across many Nigerian communities (Onwueme & Charles, 1994). Due to its high digestibility, cocoyam is recommended for children, elderly persons, and individuals with digestive disorders.

Despite its nutritional and economic value, cocoyam production in Nigeria has remained largely subsistence-oriented and underdeveloped compared to other root crops such as cassava and yam. Farmers in many rural communities continue to face numerous production challenges including poor access to improved planting materials, pest and disease infestation, declining soil fertility, inadequate storage facilities, limited mechanization, poor market access, and insufficient government support (Nwabuzor, 2001).

Climate change and environmental degradation have further compounded the challenges associated with cocoyam production. Irregular rainfall patterns, flooding, erosion, drought, and increasing temperature levels have negatively affected crop yields and farming activities in many parts of Nigeria. In addition, rapid population growth and pressure on agricultural land have contributed to reduced soil productivity and declining farm sizes.

In Ovia North East Local Government Area of Edo State, cocoyam farming constitutes an important livelihood activity among rural households. However, farmers in the area continue to experience low productivity and poor commercialization due to socio-economic and institutional constraints. Although cocoyam possesses significant potential for enhancing food security and rural economic development, its production has not received adequate policy attention compared to other staple crops.

Against this background, this study seeks to critically examine the problems and prospects of cocoyam production in Ovia North East Local Government Area of Edo State, with a view to identifying sustainable strategies for improving productivity, profitability, and rural livelihoods.

1.2 Statement of the Problem

Cocoyam production in Nigeria has witnessed a gradual decline over the years despite the crop’s nutritional, medicinal, and economic importance. Many farmers in rural communities continue to encounter serious constraints that reduce productivity and discourage large-scale cultivation of the crop. These challenges include inadequate access to improved planting materials, pest and disease outbreaks, poor soil fertility, high cost of farm inputs, lack of storage facilities, poor transportation systems, and inadequate access to agricultural extension services.

In Ovia North East Local Government Area of Edo State, cocoyam farmers operate predominantly on a small scale using traditional farming methods with limited access to modern agricultural technologies. Consequently, crop yields remain low and insufficient to meet increasing food demand and market opportunities. Furthermore, poor government support and limited access to credit facilities have restricted farmers’ ability to expand production and adopt improved farming practices.

Another major concern is the low level of value addition and commercialization associated with cocoyam production. Most farmers sell their produce in raw form with little or no processing, thereby reducing their income potential and limiting the crop’s contribution to rural economic development.

Although previous studies have focused extensively on major staple crops such as cassava, yam, and maize, limited empirical attention has been given to cocoyam production and its development potential in Edo State. This research therefore seeks to bridge this knowledge gap by examining the problems affecting cocoyam production and identifying the prospects for sustainable improvement in the study area.
