This experiment was conducted with three fertilizer levels and six plant densities in order to investigate growth, yield and contribution of yield components to dry matter yield of forage sorghum at Suweon from 1979 to 1980. The results were summarized as follows; 1. As the level of fertilizer was increased, plant height, stem diameter and dry matter yield were gradually increased. 2. According to the increase of plant density, the stem was thinned, and leaf area index and dry matter yield were markedly increased, and plant height was shortened. 3. Numbers of plant per unit area was negatively correlated with plant height and stem diameter, but LAI was positively correlated with dry matter yield and also plant height was positively correlated with stem diameter. 4. The direct effect of LA1 and plant height among yield components on dry matter yield was the highest, but the total contribution of LAI and stem diameter to dry matter yield was the highest.

This experiment was conducted to investigate the storage method of Seombadi seed(Dystaenia takesimana Nakai) in 1978, and 1979. The tested seeds were stored for 26 and 16 months at -10℃and room temperature in paper, polyethylene and cotton bags, respectively. The results are summarized as follow : 1. regardless of treatments, sound seeds of Seombadi required in general about 40 days for germination. 2. Until 26 months after harvest the germination rate of seed stored at -10℃ was 41.7 to 55.5 percentage but seed stored at room temperature was nearly zero percentage in 12 months after harvest. 3. In case of storage at low temperature (-10℃), the germination rate of seed produced in both years was similar regardless of packing materials. 4. In case of storage at room temperature, the germination rate of seed produced in 1978 was different in accordance with packing materials. After storage for 12 months at room temperature, the germination rate of seed packed with paper or cotton bags was 9.7 or 8.0 percentage, but the seed packed with polyethylene was 52.3 percentage at 16 months after harvest. It was concluded that, polyethylene bag as packing material for seed storage at room temperature was effective.
