The machine has already been used in some rural communities including those of Samchon County, South Hwanghae Province, from a few years ago, drawing attention from experts and peasants.

Per-hectare yield of rice in basic and sandy fields and reclaimed tideland sowed by the machine showed a more than 20 percent gain.

It, which can sow seeds in two or three hectares of paddy field a day, has been accepted by many other farms.
