Factors influencing pneumatic precision corn planter adoption in the Philippines: An empirical study using the Technology Acceptance Model (TAM) and Partial Least Squares Structural Equation Modeling (PLS-SEM)

Abstract

This study applies the Technology Acceptance Model (TAM) to evaluate the factors influencing the adoption of pneumatic precision planters in corn farming in the Philippines. Da-ta from 393 farmers were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to examine the relationships between Perceived Usefulness (PU), Perceived Ease of Use (PEU), Behavioral Intention (BI), and three extended TAM constructs: Compatibility (CO), Observability (OB), and Personal Innovativeness (PI). The model was validated for reliability and discriminant validity, with the Average Variance Extracted (AVE) ranging from 0.664 to 0.823. Statistical significance was observed in ten out of twelve hypothesized relationships, indicating a high likelihood of adoption. This study extends TAM by incorporating external factors such as CO, OB, and PI, offering a deeper understanding of how these variables influence farmers’ perceptions of the technology’s usefulness and ease of use. The findings suggest that, for successful adoption, policymakers should focus on enhancing the visibility of the technology’s benefits, ensuring compatibility with existing farming practices, and promoting openness to innovation through targeted education and support. The results highlight the need for practical interventions, such as educational programs and demonstration projects, which could significantly improve technology adoption, productivity, and sustainability in Philippine agriculture.
