Agricultural mechanization has been integral to agricultural transformation during periods of development. Mechanization‐service provisions can be constrained by economies of scale, seasonality, limited mobility, or heterogeneous inputs quality. However, information has been scarce regarding how the private sector has overcome these constraints especially in countries like Nigeria that are at low agricultural development stages. We present the results of a small survey of tractor owner‐operators conducted in Nigeria. We find that existing private‐sector tractor‐hiring services in Nigeria are indeed constrained. However, we also find heterogeneity among these owner‐operators. In particular, those who buy tractors from private markets or from private individuals are more efficient than those who receive tractors through government programs, providing services to a greater area at lower costs, including during off‐peak seasons, sometimes selecting machinery types according to soil types. We conclude with a discussion of some policy implications.

Knowledge gaps remain as to how longer-term public investments (PI) such as agricultural research and development (R&D), and short-term interventions through other public expenditures in agriculture (PEA) complement each other in enhancing productivity and efficiency in the agrifood sector. This study attempts to partly fill this gap by using nationally representative panel household survey data, subnational PEA data, locations of national agricultural R&D, and various spatial agroclimatic data in Nigeria. The analyses generally indicate that marginal returns to agricultural inputs/services (fertilizer, agricultural mechanization, irrigation, extension, agricultural equipment, and family labor) often increase by PI that raise overall agroclimatic similarity (AS) (through R&D locations), as well as increase PEA-share by subnational governments. There is often complementarity between these PI and PEA, particularly for extension services, investment in agricultural equipment, irrigation, and in the northern part of the country. Promoting further adoptions of modern inputs/services, increasing PEA-share, and selecting PI for agricultural R&D given in-country variations in agroclimatic conditions can help raise agricultural profitability and incomes in Nigeria. ; Non-PR ; IFPRI1; 1 Fostering Climate-Resilient and Sustainable Food Supply; 4 Transforming Agricultural and Rural Economies; NSSP; CRP2; Feed the Future Nigeria Agricultural Policy Project ; DSGD; PIM ; CGIAR Research Program on Policies, Institutions, and Markets (PIM)
