| dc.description.abstract | This research evaluated the performance of a solar power-driven pump irrigation system in San Jose City, Nueva Ecija through tree trials conducted at different times of the day. The trials, starting at 9:00 am, 12:00 pm and 3:00 pm, involved continuous data collection for 30 minutes, including ambient conditions, PV temperature, solar array characteristics, solar input and output parameters, and discharge rates. Subsequently, pump and system efficiencies were determined, revealing that in trial 1, pump efficiency was 74.90% and system efficiency was 18.40%. In trial 2, pump efficiency was 77.75% and system efficiency was 15.85%, while in trial 3, pump efficiency was 76.77%, and system efficiency was 18.26%. Water drawdown measurement were taken before and after the operation of the Solar Power driven Pump Irrigation System (SPIS). At 8:00 am, the drawdown was 5.12 mbgs, at 12:00 pm, it increased to 5.19 mbgs, and 4:00 pm, it further rose to 5.28 mbgs, indicating a 0.16 mbgs decline from the initial measurement over an eight-hour operational period. Crafting a cropping calendar, using the SPIS as the main source of water or irrigating a 10-hectare field. The system employed direct water transfer through pipes to the field, aiming to eliminate or minimize losses during the irrigation process, adhering to the guidelines of the Philippine National Standard PNS/BAFS/PAES 217:2017 ICS 65,060.35. The cropping calendar, applicable to both rice and maize, is determined based on the stages of rice growth. To optimize irrigation scheduling, the study incorporated the Blaney-Criddle Method for meticulous computation of potential, evapotranspiration (PET). Additionally, Thornthwaite’s method was employed to compute PET, utilizing forecasted weather data from the PAGASA 2024 Weather Outlook. Thus, the research aimed to enhance water use efficiency and crop yield by aligning irrigation practices with the specific requirements of rice and maize crops. This systematic approach sustainable agricultural practices guided by established standards and climate predictions. | |
