Intermitten Irrigation on Rice Varieties in Watersheds

International rice experts argue that Green Revolution technology negatively impacts soil physicalchemical conditions and calls thwas phenomenon soil soil fatigue or soil sickness. There was a tendency for input efficiency to be lower. To achieve the same level of rice production, more inputs were needed, and the rate of increase in production tends to be sloping, even decreasing (Fagi et.al, 2009). The interaction of the contribution of water irrigation x superior varieties x fertilizing accounted for 75%. So, even though irrigation water contributes the most, but it does not have a big impact if it was not planted with superior varieties, and superior varieties need high-dose fertilization. In total irrigated rice accounts for around 54% of national rice production (FAO, 1996; Huke and Huke, 1998).
