Rice that can maintain their canopies above the water in slowly rising flood as deep as several meters. It can take gradually increasing water level up to several meters at a maximum rate of 15 cm per day, provided there is adequate growth at the seedling stage approximately six weeks before the onset of flooding. Examples are floating rice varieties grown where maximum water depth ranges between 1 and 6 m for more than half of the growth duration. In densely populated areas, floating rice is grown as a subsistence crop because no other crop will grow.
