1.1 Introduction
Agricultural mechanization refers to the application of engineering and technological principles to agriculture, particularly through the use of machinery and tools to enhance farming operations such as land preparation, planting, irrigation, harvesting, and post-harvest processing (FAO, 2021). It involves the replacement or reduction of human and animal labor with mechanical power, thereby improving efficiency, reducing production time, and increasing output. In the context of developing nations like Nigeria, agricultural mechanization is regarded as a critical driver of agricultural transformation and rural development. The agricultural sector is a cornerstone of Nigeria's economy, employing a significant portion of the population and contributing to food security, income generation, and industrial raw materials (National Bureau of Statistics, 2020).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Research hypothesis and questions, Limitation of the study and Definition of terms.
1.2 Background of Study
In Nigeria, the adoption of agricultural mechanization came much later and has followed a different trajectory due to varying socio-economic and environmental conditions. Agricultural development in Nigeria prior to independence in 1960 was largely traditional and labor-intensive, relying on simple tools such as hoes and cutlasses. After independence, successive governments recognized the importance of mechanization as a means of modernizing agriculture and improving national food security. According to Akinola (2019), early initiatives such as the establishment of tractor hiring units and farm settlements during the 1960s and 1970s aimed to introduce mechanized farming to rural communities.
Agriculture remains one of the most important sectors in the Nigerian economy, serving as a major source of employment, food supply, raw materials for industries, and foreign exchange earnings. According to the National Bureau of Statistics (2020), agriculture contributes approximately 25% to Nigeria's Gross Domestic Product (GDP) and employs about 70% of the labor force, particularly in rural areas. Despite its significance, the sector continues to grapple with challenges such as low productivity, limited access to technology, poor infrastructure, and over-reliance on manual labor.
Agricultural mechanization has been identified as a transformative tool that could potentially address these persistent issues and enhance agricultural development. According to the Food and Agriculture Organization (FAO, 2021), mechanization plays a key role in reducing human drudgery, increasing land use efficiency, and enhancing the timeliness and quality of farming operations. The organization reported that mechanized agriculture not only boosts food production but also contributes to rural employment and poverty reduction when implemented effectively.
Oladele (2019) asserted that the use of modern agricultural machinery such as tractors, planters, harvesters, and threshers significantly improves farm output and operational efficiency, particularly when accessible to smallholder farmers. However, he also noted that high acquisition costs and inadequate infrastructure for maintenance have limited the widespread adoption of these tools in Nigeria. In a similar vein, Adisa and Adekunle (2018) affirmed that farmers in rural areas face challenges such as lack of technical knowledge, poor access to credit, and insufficient government support, which hinders the diffusion of mechanization practices.
Edeh et al. (2017) stated that while agricultural mechanization has been promoted through various government interventions, its actual impact on productivity remains limited due to poor implementation and lack of continuity in policies. They contend that effective mechanization requires not just the provision of machines, but also the development of support systems including training, repair services, and a reliable supply chain for spare parts (Edeh et al., 2017).
Arokoyo (2020) affirmed that in countries where mechanization is properly integrated into the agricultural system, there is a noticeable improvement in food security, farm incomes, and overall rural development. However, he reported that in Nigeria, disparities in access to mechanized services and uneven policy impact have widened the gap between commercial and subsistence farmers. This study is set against the backdrop of understanding how the use of agricultural mechanization influences the development of agriculture in Nigeria.
1.3 Statement of Problems
Investigation revealed that the agricultural sector is still dominated by traditional practices such as the use of hoes and cutlasses, which limit productivity and efficiency. Many farmers rely heavily on manual labor, which is time-consuming and less effective in large-scale operations. As a result, the output per hectare remains low, post-harvest losses are high, and the sector struggles to meet the growing food demands of the population (FAO, 2020). Furthermore, the lack of technical know-how, insufficient government support, poor infrastructure, and the absence of credit facilities further restrict the adoption of mechanized farming systems (Oladele, 2019).
On the other hand, where mechanization has been adopted, there are indications of improved crop yield, better time management, and higher income for farmers. However, the unequal distribution of such benefits raises questions about the actual impact of mechanization on agricultural development across different regions and farming communities. There is also concern about the environmental implications of large-scale mechanized agriculture, especially in areas where sustainable practices are not enforced. It is against this backdrop that this study seeks to explore the impact of the use of agricultural mechanization on the development of agriculture.
1.4 Aim and Objectives of Study
The aim of this study is to assess the impact of the use of agricultural mechanization on the development of agriculture in Nigeria. In achieving this aim, the following specific objectives were laid out as follows:
- To determine the relationship between agricultural mechanization and crop productivity.
- To evaluate how mechanization influences farmers' income and standard of living.
- To identify the challenges affecting the adoption of agricultural mechanization.
- To assess the role of government and private sector support in promoting mechanization.

1.9 Definition of Terms
Agricultural Mechanization:
This refers to the use of machinery, tools, and equipment to carry out farming operations efficiently. It includes mechanized systems for tilling, planting, harvesting, irrigation, and post-harvest processing (FAO, 2021). In this study, mechanization is considered a key driver of agricultural modernization in Nigeria.
Development of Agriculture:
This implies the transformation and growth of the agricultural sector through increased productivity, improved farming techniques, better market access, and enhanced livelihoods. It encompasses both economic and social progress within farming communities (World Bank, 2020).
Smallholder Farmers:
These are farmers who cultivate relatively small plots of land, usually less than five hectares, and rely primarily on family labor. They are often resource-constrained and form the bulk of Nigeria's agricultural population (IFAD, 2019).
Productivity:
In the agricultural context, productivity refers to the output of crops or livestock per unit of input (such as labor, land, or capital). Higher productivity means better efficiency and greater yield from the same resources (OECD, 2020).
Mechanization Services:
These include the provision of farm machinery and related support (e.g., leasing, repairs, and training) by government agencies or private firms. Such services are essential for farmers who cannot afford to own equipment.
