Abstract
This study developed a Two-Way Mobile Agricultural Spraying Machine (TWMASM) to address the ergonomic and health risks associated with manual knapsack sprayers used by Filipino farmers. Utilizing a Design and Development Research (DDR) approach, the machine was fabricated with a steel frame, a 16-liter tank, and a six-nozzle boom, powered by both a manual chain-drive and a solar-electric system. Performance trials on a corn plot revealed that the solar-powered mode significantly outperformed the manual mode, achieving a mean field efficiency of 54.92% compared to 36.51% (p < 0.05). Economically, the prototype was constructed for ₱7,100.00 with a Benefit-Cost Ratio of 4.00, indicating high viability. By providing a cost-effective, ergonomic, and efficient alternative, the TWMASM supports the Philippine Farm Mechanization Roadmap while enhancing farmer productivity and safety.
