Abstract
Solar Water Pump Irrigation System (SIPTS) is a renewable energy to solve water problem in agriculture. SIPTS could reduce greenhouse gas emissions and draw water to agricultural lands through supplementary irrigation. The objectives of research are to design a SIPTS for drip irrigation and to calculate the irrigation efficiency of SIPTS and GHG emission reduction. The results of the study indicate that the use of SIPTS could save fuel consumption from 70 to 14 L ha−1 season−1, resulting in a savings of 400%. Furthermore, the use of SIPTS could reduce GHG emissions originating from the use of hydrocarbon materials from 0.176 to 0.035 t of CO2 which is more environmentally friendly. In addition, the results of water content analysis show that the use of SIPTS with streamline drip irrigation has relatively higher water content than that of farmers’ irrigation practices, this indicates that irrigation system is more effective in distributing water horizontally and vertically. Likewise, plant growth and shallot yield represented indicate higher growth and yield compare to farmers’ practices.
