| dc.description.abstract | The university rehabilitated the 2.44-kilometer deteriorating supply ditch canal to increase the irrigated areas and improve productivity in the selected R&D centers. The study evaluated the performance of the rehabilitated irrigation system by measuring the system delivery, productivity and economic performance. The results show that a higher system delivery performance is obtained following a rotational irrigation scheme with a conveyance efficiency equal to 94.78% to 95.78% in outlets 5, 13 and 17 and field application efficiency equal to 74% to 86% in outlets 1, 9, and 14. The measured volume of water diverted weekly in the supply ditch canal was not insufficient to reach some command areas. This may be affected by the ineffective cross sectional of the canal that was not covered in the rehabilitation. After the system’s rehabilitation, the command areas, gross income, and output per command area were somewhat that increased. From an economic perspective, after the rehabilitation, the selected command areas have a reduction in irrigation cost about Php 6,898.27 ha/year, Php 31541.21 ha/year and Php 1137.68 ha/year in the upstream, midsection, and tail end sections of the ditch canal, respectively. Through this findings, the study recommended the implementation of rotational irrigation scheme to ensure the equal distribution of total water being delivered to all outlets. Also, proper scheduling based on the farm irrigation requirement of the crops planted in the respective command areas need to implement to improve the efficiencies, increased the productivity and ensure economic viability in all canal sections. | |
