The planted plant is rice plant. In planting, an application amount of nitrogen is preferably 1.1 to 2 times of that of the ordinary rice planting. The soil moisture state after the maximum tillering stage is preferably set to a level of a moisture content of muddy fields or a moisture content of capillary disconnection. The rice plant is preferably an Indian breed and/or an Indian-Japanese hybridized breed, especially preferably a hardly-shattering Indian breed.
