This experiment was conducted to select optimum minor cereal crop and variety for the marginal agricultural lands so that they would be used to increase the agricultural land use rate in mountainous areas. This experiment used three different marginal agricultural lands, that is, slope land, barren land and gravelly land. Soil pH of control field was 7.85, slightly alkali, whereas gravelly land showed strong acid(pH 5.1). EC of marginal agricultural lands was generally lower compared to the control, especially barren land showed 0.05dS m -1 which was the lowest among marginal agricultural lands. Foxtail millet showed no significant difference of heading and ripening date among marginal agricultural lands. Foxtail millet of slope land showed the highest culm length( 169.5 cm) and grains per ear(4913.9 grains) among marginal agricultural lands except control field. Growth duration of three varieties was varied from 112 to 113days, which was not different statistically. In grains per ear of common millet, slope land showed 787.1 grains which was the highest among marginal agricultural lands except control field. Among varieties, Byorukgijang showed the highest grains per ear(827.2 g/ear), whereas 1000 grain weight was 5.5 g which was lower compared to that of Hwanggijang(6.2g). In sorghum, slope land showed the highest grains(2563.8 grains) per ear and ears per 3.3 m²(26.0 ears) except control field. Growth duration of three sorghum varieties almost the same from 122 to 123 days, whereas the highest grains per ear was obtained from Moktaksusu(2357.6 grains). Jangmoksusu showed the highest 1000 grain weight(23.8 g) among three sorghum varieties. In yield of three foxtail millets, the highest yield was obtained from slope Iand(282.0 kg/10a) among marginal agricultural lands and Mongdangjo showed the highest yield(252.3 kg/10a) among three varieties. In yield of three common millets, the highest yield was obtained from slope land( 196.0 kg/10a) among marginal agricultural lands and Byorukgijang showed the highest yield( 173.8 kg/10a) in three varieties. In three sorghum varieties, the highest yield was obtained from slope land (301.7 kg/10a) among marginal agricultural lands and Moktaksusu showed the highest yield(236.5 kg/10a) among three varieties.
