This experiment was canied out to investigate the effect of seeding times on the fresh yield of fodder beet varieties, and to select the most adaptable varieties of fodder beet in Daekwanryeong areas. Three varieties(Kyros, Zorba and Hugin) and six seeding times(25 July, 4 Aug. and 14 Aug. in 1993. and 30 Apr., 10 May and 20 May in 1994) were combined in the experiment. The results obtained were as follows: 1. The seeding time for the highest fresh yield of fodder beet was obtained as 18.29 tonha on 25 July in 1993. Of various varieties, the highest fresh yields were 22.59 ton and 18.89 tonlha for Kyros and Zorba on 25 July, and 19.15 tonha for Hugin on 4 Aug. in 1993. 2. The fresh yield of fodder beet were 20.30 ton, 19.41 ton and 16.93 tonlha on 30 Apr., 10 May and 20 May in 1994, respectively. The highest fresh yield of the varieties were 77.78 ton for Kyms on 20 May, 19.79 ton for Zorba on 30 Apr., and 20.63 tonha for Hugin on 10 May in 1994. 3. Shoot and root(S/R) ratio was different between seedling times. S/R ratio of the varieties were increased in 1993 due to the delayed seeding times, but on the contrary it tended to decrease in 1994 with the delayed seeding times. 4. Shoot and root(S/R) ratios of varieties were 0.94, 0.89 and 1.18 for Kyros, Zorba and Hugin in 1993, and 1.29 for Kyms, and 1.85 for Zorba and Hugin in 1994, respectively.
