Five varieties of silage corn were cultivated to compare the growth characteristics and productivity. Corn varieties were Pioneer 3144(P 3144), 3160(P 3160), 3282(P 3282), 3352(P 3352) and Suweon 19 (S 19). The corns were seeded on May 2 and harvested on August 15, and measured the plant height, leaf length, leaf width, stem diameter, and yields of fresh and dry matter. The results obtained were as follows: 1. Plant height of P 3352 and P 3144 grown about 280cm throughout the experimental period was the tallest(P<.Ol), and those of P 3160, P 3282 and Suweon 19 ranged from 246.3 to 256.0 cm. 2. Leaf length is the longest in P 3352 and the shortest in P 3282(97.63cm vs 84.17cm), and there was significant(P<.Ol) difference between corn varieties. 3. Stem diameter was the longest in P 3144 and the shortest(P<.Ol) in P 3352(3.28cm vs 2.66cm). 4. P 3144, P 3282 and P 3352 had the greatest(P<.Ol) fresh matter yields per 10a in leaf, stem, and ear and whole plant, respectively. 5. Dry matter yield of P 3282 was the greatest(P<.Ol) in stem(1,080.6 kg/lOa) and leaf(304.5 kg/lOa), and that of P 3352 was the greatest in ear(864.1 kg/lOa) and whole plant yield(2,021 kg/lOa). 6. Ratios of respective part of corn to total dry matter were ranged from 12.7 to 17.8 76 for leaf, 44.5 to 66.9% for stem and husks, and 16.9 to 42.8 % for ear, and the highest in P 3160, P 3160 and P 3352, respectively. Consequently, P 3352, P 3144 and P 3282 shown high productivity in dry matter yield could be recommended as a reliable corn varieties for silage.
