A gel-coating apparatus for seeds comprising: a nozzle portion for forming and cutting a gel coating film by opening and closing operation of a cutting plunger; a seed storing vessel moving upward and downward; an arm having a rotation shaft at the center thereof and a hollow needle at both ends thereof; a seed supply portion having pipes for communicating the needles with a negative pressure source and a positive pressure source by way of electromagnetic valves; a curing vessel provided below the nozzle portion; and a control section for synchronously operating the movement of the curing vessel, the nozzle portion, the seed storing vessel, the arm, and the seed supply portion. With the above apparatus, a method of gel-coating seeds according to the present invention comprising the steps of gel-coating seeds into a larger spherical form, immersing the seed into a curing agent for a predetermined period of time to cure the surface of the gel-coating layer and, subsequently, taking the gel-coated seed out of the curing agent, washing out the deposited curing agent with water and curing only the surface of the layer.
