Abstract

The operational practices and maintenance procedures employed for the Mayao Diversion of the Dumacaa River Irrigation System was observed and the system's performance was evaluated through the cropping intensity, average yield, Irrigation Service Fee (ISF) collection efficiency and water conveyance efficiency. Upon observation, it was found out that the system has poor operation and maintenance procedures. There are no existing cropping calendar and irrigation scheduling being followed in the system. However, the cropping intensity of 145.38% is higher than the 135% average cropping intensity in the country as reported by the Department of Agriculture (DA). The 4 tons/ha and 3.5 tons/ha average yields for the dry and wet seasons, respectively, are also within the average yield of 3.59 tons/ha reported DA. The ISF collection efficiency of 65.80% is also commendable since the average ISF collection efficiency is 60% according to Raby (1997). In evaluating the system's performance, the water conveyance efficiency was determined to be 57.10%, 62.00% and 40.58% for laterals B, B-1 and B 11c respectively. The low conveyance efficiencies result from improper operational practices and poor maintenance procedures. Nevertheless, the system can still supply sufficient amount of water to the farms.
