Impact Assessment of Site-Specific Nutrient Management Projects for Sustainable Crop Production

บทคัดย่อ

     Extension of knowledge on appropriate fertilizer use to farmers is important. Projects on Site-specific nutrient management for sustainable crop production has transferred the technology to target farmers. An impact assessment of this research project is useful for the policy implication. The objective of the article is to evaluate the benefit of the research. The results demonstrated that an appropriate fertilizer use not only enhances yield but also reduces production costs and increases net incomes to the farmers. An economic evaluation found that investment in this research project is worthwhile. The economic benefit generated from the projects will be higher when there is a wider adoption of this technology among rice farmers in irrigated areas. The study suggests that it is important for conceiving the technology to the national policy.
