Renewable Irrigation System in the Land Rice Field of Subak in Bali

Subak as Bali's traditional organization functions mainly in the distribution of irrigation water in paddy fields, have to reorganize the system of irrigation in rice fields (paddy). Distribution of irrigation water in paddy fields in Bali Subak be reorganized back in tune with the amount of irrigation water decreased, without having implications for the reduction of rice production per unit area. Thus the traditional irrigation system in Subak need to be reconstructed and adjusted for the increasingly limited availability of water, by applying a model of renewable in the irrigation system. In this context there is an interesting problem to be studied, as formulated in the following research questions. What forms of renewable irrigation system conducted by several subak in Bali? The conclusions of this study are as follows. Renewable forms of irrigation systems applied in both Subak, between Subak Wangaya Betan and Subak Gunungsari are growing rice in paddy fields with irrigation system is interrupted (intermittent irrigation). Rice plants are not aquatic plants, but it requires water, in this way grow rice in waterlogged soils or irrigation interrupted (intermittent irrigation), allow the soil to provide more oxygen when compared to the state flooded. So that was allegedly caused by the process of respiration and water absorption are in balance, then the roots can grow better, bigger and more powerful, so the implication is the sequel plants can absorb nutrients properly, eventually plant growth and development has also improved.
