Abstract
In an iron powder for coating a seed, the mass percentage of an iron powder with a particle size of 63 μm or less is 0% to 75%, the mass percentage of an iron powder with a particle size of more than 63 gm to 150 μm is 25% to 100%, and the mass percentage of an iron powder with a particle size of more than 150 μm is 0% to 50%. This allows the iron powder to form a coating from which the iron powder is unlikely to drop during not only seeding but also transportation and also allows an iron powder-coated seed coated with the iron powder to be obtained. The following iron powder and rice seed can be obtained: an iron powder, unlikely to damage rice seeds and easy to handle, for coating a rice seed and an iron powder-coated rice seed coated with the iron powder.
