BANANA AND PLANTAIN MARKETING IN ENUGU STATE, NIGERIA

ABSTRACT

This study analyzed the marketing of banana and plantain in Enugu State, Nigeria. The specific objectives were to: describe the socio-economic characteristics of banana and plantain marketers; identify the marketing channels for the crops; examine the structure of the marketing system for both crops; estimate their marketing margins at wholesale and retail levels; estimate the rate of price transmission and market integration among banana and plantain markets; and identify the constraints facing the marketing of both crops. The study adopted a survey research design with a multi-stage sampling technique to compose a sample of 160 respondents (30 wholesalers and 50 retailers for banana, and 30 wholesalers and 50 retailers for plantain). Data were collected from both primary and secondary sources using structured questionnaires and time series data from Enugu State Agricultural Development Programme (ENADEP). Data were analyzed using Gini coefficient, marketing margin analysis, Johansen co-integration test, Vector Error Correction Model, and descriptive statistics. The results showed that the majority of respondents (87.50%) were females with an average age of 35 years, 76.20% were married, and 41.20% attained primary education. The mean household size and marketing experience were seven and 13 years respectively. Marketing channels were characterized by 78.30% of wholesalers obtaining products in heaps directly from producers, while 78.00% of retailers obtained products in bunches from wholesalers. The Gini coefficient results indicated low levels of inequitable income distribution, though inequalities were higher at retail than wholesale levels. The mean marketing margin for plantain (21.62%) and banana (13.68%) retailers showed significant differences, while margins for wholesalers (11.65% and 10.58%) did not differ significantly. Price transmission analysis revealed low rates of adjustment between rural and urban markets, though market integration was present. Major constraints included low capital, inadequate finance, high transportation costs, and heavy imposition of taxes/levies. The study recommends that government should establish fiscal and monetary policies to stabilize prices, provide adequate credit to market participants, and improve infrastructure and market information systems for enhanced marketing of banana and plantain.

CHAPTER ONE

INTRODUCTION

1.1 Background of the Study

Banana and plantain are among the most important staple food crops in Nigeria, contributing significantly to food security, nutrition, and livelihoods, particularly in the southern and southeastern regions of the country. These crops belong to the genus Musa and are cultivated extensively in the humid and sub-humid tropics, where they serve as major sources of carbohydrates, vitamins, and minerals for millions of people. In Nigeria, banana and plantain rank among the leading starchy staples, with the country being one of the largest producers in West Africa. The crops are predominantly grown by smallholder farmers, often as intercrops or backyard gardens, and play a vital role in the rural economy, providing income and employment opportunities for both producers and marketers (Obetta, 2021; Ukwuaba et al., 2022).

The nutritional importance of banana and plantain cannot be overstated. Both crops are rich in complex carbohydrates, dietary fiber, potassium, vitamin C, and vitamin B6, making them valuable components of a balanced diet. Plantains, in particular, are a staple food in many Nigerian households, consumed in various forms including fried (dodo), boiled, roasted, and processed into flour for baking. Banana, while also consumed fresh, is increasingly used in the production of value-added products such as banana chips, juice, and baby food. The increasing awareness of the nutritional benefits of these crops has led to a rise in their consumption across all income groups, driving demand and expanding market opportunities for producers and marketers (Ebere and Chukwuemeka, 2018).

Enugu State, located in the southeastern geopolitical zone of Nigeria, has emerged as a significant hub for banana and plantain production and marketing. The state’s tropical climate, with adequate rainfall and suitable temperatures, provides favorable conditions for banana and plantain cultivation. The crops are grown across the state, particularly in areas such as Nsukka Local Government Area, which has large market centres operating daily or every four days, where agricultural products including banana, plantain, vegetables, palm oil, honey, and other fruits are commonly traded (Ukwuaba et al., 2022). In the area, banana and plantain are mostly cultivated mixed with other plants, as backyard crops in compound farms, where farmers usually have less than 50 stands, with a greater proportion of them growing more banana than plantain.

The marketing of banana and plantain involves everything that happens between the farm gate and the consumers, including processing, storage, assembling, wholesaling, and retailing. Banana and plantain marketing is one of the driving forces for economic development of the rural areas, as marketing has a guiding and stimulating impact on the production and distribution of these products. The transformation of the production system requires the existence of an efficient market system that can transfer the products from the points of production to the required market at the least possible cost, so as to improve the living standard of rural dwellers. The process is referred to as marketing channel, which represents the various means by which the fruits move from the producers to the consumers (Obetta, 2021).

In Enugu State, the banana and plantain marketing channel is highly decentralized. The products are usually assembled at local markets from where wholesalers make bulk purchases. In urban areas, wholesalers sell to retailers who, in turn, resell in smaller quantities to ultimate consumers. However, in rural areas, there are no established large marketing facilities. Rather, wholesalers purchase directly from farmers. This decentralized structure presents both opportunities and challenges, as it enables local participation in the marketing system but also creates inefficiencies due to multiple handling, high transaction costs, and limited market information (Ebere and Chukwuemeka, 2018).

Women play a dominant role in banana and plantain marketing in Enugu State, as in many parts of Nigeria. The sale of banana and plantain provides a means of livelihood for many households, particularly women, hence its decentralization, as both wholesalers and retailers purchase their commodities directly from producers. In urban centres, the wholesalers sell to the retailers who in turn resell smaller quantities to the ultimate consumers. This prominent role of women in the marketing system has implications for gender equity, household welfare, and the design of interventions aimed at improving the efficiency and inclusiveness of the marketing system (Ukwuaba et al., 2022).

The structure of the marketing system for banana and plantain in Enugu State encompasses the features of market organization that influence the nature of competition and pricing within the market. These characteristics include the number of buyers and sellers in the market, knowledge of costs, prices, and market conditions among marketers. The increase in the number of market dealers in banana and plantain reflects the growing importance of these crops for livelihoods. However, studies have noted that the increase in farm output has not led to a corresponding increase in the earnings of the vast majority of farmers. One of the factors responsible for this imbalance is a poorly developed agricultural marketing system for major food staples such as banana and plantain, leading to high rates of spoilage, rise in product prices, and poor export performance (Ayinde et al., 2009; Obetta, 2021).

Marketing margins, which represent the difference between the prices paid by consumers and the prices received by producers, are critical indicators of market efficiency and the distribution of benefits among market participants. For banana and plantain in Enugu State, studies have shown that the marketing margin for plantain retailers (21.62%) and banana retailers (13.68%) differ significantly, while margins for wholesalers (11.65% for plantain and 10.58% for banana) do not differ significantly. These margins reflect the costs of marketing activities, including transportation, storage, and handling, as well as the profits of intermediaries. The higher margins for plantain compared to banana may reflect differences in perishability, handling requirements, and market demand (Obetta, 2021).

Price transmission and market integration are essential aspects of market efficiency, indicating the extent to which price changes in one market are transmitted to other markets. In efficient markets, prices in spatially separated markets are expected to move together in the long run, reflecting the absence of arbitrage opportunities and the smooth flow of information and goods. For banana and plantain in Enugu State, analysis of price transmission has shown that the Error Correction coefficients (-0.22 and -0.25 for banana, and -0.12 and -0.30 for plantain) indicate low rates of price transmission between rural and urban markets, although market integration is present. This low rate of price transmission suggests that price adjustments are slow, potentially due to information asymmetries, transportation constraints, and other market imperfections (Obetta, 2021).

The constraints facing banana and plantain marketers in Enugu State are numerous and interrelated, affecting the efficiency and profitability of the marketing system. Low capital/initial investment, inadequate finance, high cost of transportation, heavy imposition of taxes and levies, seasonality of plantain, price fluctuations, bulkiness, and spoilage/breakage have been identified as significant constraints. The marketers experience huge losses during marketing, which poses a great challenge as they are constrained to offer products for sale at any price to avoid further spoilage. This affects the economic development of the area as traders are hindered from making better decisions, especially in rural areas (Obetta, 2021; Ukwuaba et al., 2022).

The wide gap between rural and urban prices of banana and plantain in Enugu State weakens farmers’ morale, thereby reducing productivity. This invariably affects rural community development. Therefore, to increase production in the state, there is a need to develop a more efficient marketing system with market information. This enables prices in one market to be transmitted to other markets, thus synchronizing prices and improving the economic capabilities of rural marketers. This, in turn, improves the standard of living of rural dwellers. Poor post-harvest handling practices, amongst other problems, have been militating against agricultural production in Nigeria, observing that the problem of productivity is further compounded by poor storage and marketing, thus, aggravating loss of quality and quantity, hence, affecting the final price of agricultural commodities (Ukwuaba et al., 2022).

Plantain is seasonal and its shelf life is relatively short; hence, its availability is for limited periods of time, thereby incurring very high post-harvest losses. Studies on plantain marketing have shown that plantain fruits are subjected to adverse conditions during handling and transportation. The marketing of plantain is very difficult because of the dispersal of the production zones, the lack or poor conditions of the lines of communication with urban consumption centres, and the irregular supply in the market by wholesalers and middlemen who set the prices. It is insufficient for policymakers to focus on solving production-related problems alone, because even if production eventually becomes adequate, marketable and marketed surplus may not be enough and reliable (Ukwuaba et al., 2022).

Recent studies have shown that plantain marketing offers great profit-making potential, yet it remains unclear if this has translated to more profits, making it imperative to examine the drivers of plantain marketing. Research has shown that plantain marketing is mainly done by married educated women, averaging 40 years of age, belonging to households averaging six persons. Net monthly profit of $63.51 (₦26,050.38), average marketing margin of 30.84%, and marketing efficiency of 35.06% have been reported, suggesting that plantain marketing is profitable and viable but largely inefficient. Cost of plantain and marketing experience were found to be positively significant drivers of marketing returns (Ukwuaba et al., 2022).

The study dwelt on the decision-making roles in banana and plantain marketing, and the pattern of marketing among wholesalers and retailers in both rural and urban areas of Enugu State, Nigeria. The level of marketing channel, structure as well as the speed of price adjustment among banana and plantain markets in Enugu State has not been fully investigated and documented. Hence, the study focused on the assessment of economic implications of marketing structure of banana and plantain fruits for the development of rural communities in Enugu State, Nigeria (Ebere and Chukwuemeka, 2018).

Venturing into the plantain enterprise holds promising potentials; however, there is little study to back up marketing of plantain within Nsukka LGA, as the relatively little attention given to plantain in this study area focused on its production technology (characterization, correlation, path analysis and selection indices of Musa genotypes under different conditions). Increasing output without correspondingly increasing marketing may bring about resource wastage and as such, people may continue to wallow in poverty and food insecurity. Despite the contributions of plantain marketing to the livelihood survival of most marketers, there is little study conducted to identify the drivers of the enterprise (Ukwuaba et al., 2022).

The significance of efficient marketing systems for banana and plantain cannot be overstated. An efficient marketing system ensures that products move from areas of surplus to areas of deficit, that price signals are transmitted between markets, and that consumers have access to products at reasonable prices. For banana and plantain, which are highly perishable, an efficient marketing system is particularly important to minimize post-harvest losses and ensure that quality products reach consumers. However, the marketing system in Enugu State faces numerous challenges that compromise its efficiency, including poor infrastructure, limited market information, inadequate finance, and multiple taxes and levies (Obetta, 2021).

The study period and context are significant for understanding the dynamics of banana and plantain marketing in Enugu State. The period from 2007 to 2011, for which time series data were obtained from ENADEP, represents a period of relatively stable growth in the agricultural sector, with increasing attention to agricultural marketing as a driver of rural development. The findings of the study provide a baseline understanding of the marketing system that can inform interventions aimed at improving efficiency, reducing losses, and enhancing the welfare of market participants. However, the need for updated research that reflects current market conditions remains (Obetta, 2021).

The relationship between marketing structure and rural development is a critical dimension of the study. An efficient marketing system can stimulate production by providing farmers with better prices and access to markets, thereby increasing incomes and reducing poverty. Conversely, an inefficient marketing system can depress production by failing to provide adequate incentives to producers, leading to low productivity and continued poverty. The study’s focus on the economic implications of marketing structure for rural development recognizes this relationship and seeks to provide evidence that can inform policy and practice (Ebere and Chukwuemeka, 2018).

The study is also significant in the context of gender and development. Given the dominant role of women in banana and plantain marketing, understanding the constraints and opportunities facing women marketers is essential for promoting gender equity and empowerment. Women’s participation in marketing provides income that can be used for household consumption, children’s education, and health care. However, women marketers often face specific constraints, including limited access to finance, information, and market infrastructure, that limit their earning potential. The study’s findings on gender dimensions of banana and plantain marketing can inform interventions that address these constraints and promote women’s economic empowerment (Ukwuaba et al., 2022).

In conclusion, the background of this study establishes the context for analyzing banana and plantain marketing in Enugu State, Nigeria. The study recognizes the importance of these crops for food security and livelihoods, the critical role of efficient marketing systems, and the need for empirical evidence to inform policy and practice. The following sections of this chapter present the statement of the problem, aim and objectives of the study, research questions, hypotheses, significance, scope, limitations, and definition of terms.

1.2 Statement of the Problem

Banana and plantain are important staple food crops in Enugu State, contributing significantly to food security, nutrition, and livelihoods, particularly among rural women who dominate the marketing of these products. However, despite the importance of these crops, the marketing system faces numerous challenges that compromise its efficiency, profitability, and contribution to rural development. Understanding the nature and extent of these challenges is essential for developing effective interventions, but empirical evidence on banana and plantain marketing in Enugu State remains limited.

The marketing channels for banana and plantain in Enugu State are characterized by multiple intermediaries, each adding costs and margins, which ultimately affect the prices paid by consumers and the prices received by producers. The products are usually assembled at local markets from where wholesalers make bulk purchases, and in urban areas, wholesalers sell to retailers who resell in smaller quantities to consumers. This marketing channel, while facilitating access to markets, also creates inefficiencies due to multiple handling, storage losses, and high transaction costs. The specific characteristics of these marketing channels, including the relationships among actors and the determinants of channel choice, have not been adequately documented.

The structure of the marketing system for banana and plantain, including the number of buyers and sellers, the nature of competition, and the conduct of market participants, has important implications for market efficiency and the distribution of benefits. While there has been an increase in the number of market dealers in banana and plantain, reflecting the growing importance of these crops, the structure of the market has not been systematically analyzed. The extent of market concentration, inequalities in income distribution, and the degree of competition among marketers require investigation to inform policies that promote market efficiency and equitable outcomes.

Marketing margins, which represent the difference between consumer prices and producer prices, are key indicators of market efficiency and the distribution of value among market participants. For banana and plantain in Enugu State, studies have shown that plantain retailers earn higher margins (21.62%) compared to banana retailers (13.68%), while wholesale margins for both products are similar (11.65% and 10.58%). However, the determinants of these margins and their implications for the welfare of market participants have not been fully explored. Understanding the factors influencing marketing margins is essential for identifying opportunities to improve market efficiency and enhance the benefits to producers and consumers.

Price transmission and market integration are essential aspects of market efficiency, indicating the extent to which price changes in one market are transmitted to other markets. For banana and plantain in Enugu State, analysis has shown that the rate of price transmission between rural and urban markets is low, indicating that price adjustments are slow and market inefficiencies persist. The specific factors contributing to this low rate of price transmission, including information asymmetries, transportation constraints, and institutional factors, require investigation to inform interventions that improve market integration and synchronize prices across markets.

The constraints facing banana and plantain marketers in Enugu State are numerous and interrelated, including low capital/initial investment, inadequate finance, high transportation costs, heavy taxes and levies, seasonality, price fluctuations, bulkiness, and spoilage/breakage. While these constraints have been identified, their relative importance and the mechanisms through which they operate have not been adequately assessed. Understanding the nature and severity of these constraints is essential for prioritizing interventions and allocating resources effectively.

Poor post-harvest handling practices and the perishable nature of banana and plantain contribute to significant losses during marketing. The rate of spoilage is high, with the fruits being subjected to adverse conditions during handling and transportation, leading to loss of quality and quantity, and affecting the final price of the commodities. The extent of these losses and their implications for the profitability of marketing enterprises and the welfare of consumers require investigation to inform interventions that reduce post-harvest losses and improve product quality.

The role of women in banana and plantain marketing in Enugu State is dominant, with 87.50% of marketers being females. Despite their significant contribution, women marketers face specific challenges related to access to finance, market information, and productive resources. Understanding these gender-specific constraints and their implications for the efficiency and inclusiveness of the marketing system is essential for designing interventions that promote gender equity and women’s economic empowerment. However, the gender dimensions of banana and plantain marketing have not been adequately explored.

The relationship between marketing efficiency and rural development is a critical but underexplored dimension. An efficient marketing system can stimulate production, increase incomes, and contribute to poverty reduction and rural community development. Conversely, an inefficient marketing system can depress production, reduce incomes, and perpetuate poverty. The specific mechanisms through which banana and plantain marketing contributes to or constrains rural development in Enugu State require investigation to inform policies that maximize the development impact of the marketing system.

The gap between rural and urban prices of banana and plantain in Enugu State has been identified as a factor that weakens farmers’ morale and reduces productivity. The wide price differential reflects the inefficiencies in the marketing system, including high transaction costs, information asymmetries, and infrastructural deficits. Understanding the determinants of this price gap and the strategies for reducing it is essential for improving incentives for producers and enhancing the contribution of banana and plantain to rural development.

Limited market information and weak market information systems have been identified as constraints to efficient marketing. Information on prices, sources of supply, and market conditions is essential for decision-making by marketers, but the availability and accessibility of such information in Enugu State are limited. The nature of market information systems, the information sources used by marketers, and the implications of information constraints for market efficiency require investigation to inform the development of improved information systems.

The seasonality of plantain and the irregular supply in the market by wholesalers and middlemen create challenges for efficient marketing. The limited availability of plantain during off-seasons leads to price spikes, while glut during peak seasons leads to price crashes and wastage. Understanding the patterns of seasonality and supply variability and their implications for market stability and the welfare of market participants is essential for developing strategies to smooth supply and stabilize prices.

In light of these challenges, there is an urgent need to analyze banana and plantain marketing in Enugu State, with a focus on understanding the marketing channels, structure, margins, price transmission, and constraints. This study aims to address the knowledge gaps identified above and provide evidence-based recommendations for enhancing the efficiency, profitability, and inclusiveness of the marketing system. The findings are expected to contribute to policy development, program design, and institutional strengthening for improved banana and plantain marketing in Enugu State.

1.8 Scope of the Study

This study is delimited to the analysis of banana and plantain marketing in Enugu State, Nigeria.

Geographically, the study covers Enugu State, which is located in the southeastern geopolitical zone of Nigeria. The state is characterized by significant production and marketing of banana and plantain, particularly in the Nsukka urban and neighbouring communities, as well as other areas within the state. The study covers both rural and urban areas to capture the full range of marketing activities and the price transmission dynamics between rural and urban markets.

Content-wise, the study focuses on five key dimensions of banana and plantain marketing: the socio-economic characteristics of marketers, marketing channels, the structure of the marketing system, marketing margins, and price transmission and market integration. These dimensions were selected based on their significance for understanding the structure, conduct, and performance of the marketing system and their implications for market efficiency, profitability, and rural development.

The study focuses on the marketing of fresh banana and plantain fruits and does not address the marketing of processed products such as plantain flour or banana chips. The study also does not address the production of banana and plantain, although this is relevant for understanding supply dynamics and market performance. The study covers both wholesalers and retailers to capture the distribution of functions, margins, and value across the marketing channel.

The study population comprises banana and plantain marketers in Enugu State, including wholesalers and retailers. The study includes 160 respondents (30 wholesalers and 50 retailers for banana, and 30 wholesalers and 50 retailers for plantain). The study does not include producers (farmers) or consumers, although their perspectives could provide additional insights into the marketing system.

Temporally, the study covers the period from which time series data on retail prices were obtained (2007 to 2011) and includes current primary data collected through structured questionnaires. The cross-sectional design of the study provides a snapshot of current marketing conditions and relationships, while the time series data enable analysis of price transmission and market integration over the study period.

Methodologically, the study adopts a survey research design using structured questionnaires and secondary time series data. Data analysis employs descriptive statistics, Gini coefficient, marketing margin analysis, Johansen co-integration test, and Vector Error Correction Model. These analytical techniques are well established in agricultural marketing research and enable comprehensive analysis of the marketing system.

1.9 Limitation of the Study

This study acknowledges several limitations that may affect the interpretation and generalizability of its findings.

The use of a survey design with self-report questionnaires is one of the major limitations of this study. This design relies on respondents’ ability to accurately recall and report their experiences, practices, and perceptions regarding banana and plantain marketing. Recall bias, where respondents may not remember details of their marketing activities or transactions accurately, could affect the validity of the findings. Additionally, respondents may have provided socially desirable responses, particularly on sensitive topics such as profits, margins, and tax payments, limiting the accuracy of the data.

The sample size of 160 respondents, while adequate for the statistical analysis planned, may limit the statistical power of the study and the generalizability of the findings. The sample may not adequately capture the diversity of banana and plantain marketing experiences and practices across the different local government areas and market centres of Enugu State. A larger sample size would have enhanced the representativeness of the findings and enabled more detailed subgroup analyses.

The study was conducted in Enugu State only and may not be representative of other states in southeastern Nigeria or other regions of the country. The specific marketing conditions, infrastructure, and institutional arrangements in Enugu State may differ from those in other areas, limiting the generalizability of the findings. However, the study provides insights that may be relevant to similar agricultural marketing contexts in the region and can inform policy and practice beyond the immediate study area.

The study focused on banana and plantain marketers as the primary respondents and did not include producers or consumers, whose perspectives could have enriched the study. Producers could provide insights into production costs, supply dynamics, and relationships with marketers, while consumers could provide information on product quality, pricing, and preferences. The exclusion of these groups may have introduced a bias towards the perspectives of intermediaries.

The cross-sectional design of the study, which collects primary data at a single point in time, does not allow for the assessment of changes over time or the establishment of causal relationships between marketing practices and outcomes. The time series data on prices (2007-2011) provide some longitudinal perspective, but the primary data are cross-sectional. The study is limited to examining associations between variables and cannot determine whether marketing practices cause changes in market performance or whether other factors are responsible for observed outcomes.

The reliance on a structured questionnaire, while allowing for standardized data collection and quantitative analysis, may not have captured the full complexity of marketers’ experiences, strategies, and decision-making processes. The pre-defined response options may not have adequately reflected the range of marketing practices, constraints, and opportunities in the study area. Qualitative data collection methods, such as focus group discussions and in-depth interviews, could have provided richer insights into the dynamics of banana and plantain marketing.

Financial constraints limited the scope of the study, including the geographical coverage, sample size, and data collection methods. With more resources, the study could have included a larger sample, additional data collection methods, and a broader range of stakeholders. The financial limitations also affected the ability to conduct pilot studies and test the research instrument extensively before the main data collection.

Time constraints were another limitation, as the study had to be completed within a specific academic timetable. This limited the ability to conduct extensive community mobilization, engage in prolonged fieldwork, and verify responses through repeated visits or triangulation with other data sources. The study also could not include more recent time series data beyond 2011 to capture current price transmission dynamics.

Language and communication challenges may have affected the quality of data collected, particularly if research assistants did not have adequate proficiency in the local languages spoken by respondents. Translating complex concepts such as marketing margins, market integration, and price transmission into local languages may have led to some loss of meaning or misunderstanding. The use of trained research assistants and careful translation of the questionnaire mitigated this limitation.

Cultural norms and social dynamics may have influenced responses, particularly on sensitive topics such as business profits, tax payments, and relationships with other marketers. Respondents may have been reluctant to disclose information that could be perceived as exposing them to competition, tax authorities, or social disapproval. Efforts to ensure confidentiality and build rapport with respondents helped to mitigate this limitation.

Despite these limitations, the study provides valuable insights into banana and plantain marketing in Enugu State and offers a foundation for further research and policy development. The limitations identified do not invalidate the findings but should be taken into account when interpreting and applying the results.
