Water management in Philippine irrigation systems: research and operations. Los Banos, Laguna, Philippines: International Rice Research Institute (IRRI). pp.155-182.
(Location: IWMI-HQ Call no: 631.7.6 G732 INT Record No: H016)
A research project was carried out on large sites within irrigationsystems to determine the benefits of irrigation to yields of lowland rice. Datawere collected under farm level conditions to establish yield response to days of moisture stress. A model was then developed and employed to relate irrigation, rainfall and water-use parameters to days of moisture stress, and thus to yields. Although yield benefits due to irrigation were substantial for both seasons, they were seriously depressed because of imperfect irrigation, particularly in the dry season. Neither the height of paddy bunds nor the amount of rainfall in the sites were of major consequence to grain yield. Considerable variation in water-use was observed among the sites, but it was generally found that sites with low water-use efficiencies showed the greatest yield benefits, and vice versa.
