A field experiment was conducted to evaluate growth characteristics, dry matter yield and crude protein yield according to different planting dates at sorghum $\times$ sudangrass hybrid(SSH) and soybean intercropping. Planting dates were five treatment of may 6(Tl), may 13(T2), may 20(T3), may 27(T4) and june 3(T5), and cutting frequency was two times a year. 1. Plant length of SSH was the highest at T2 as 253cm, but T5 was the shortest as 203cm. In the soybean, T3 and T4 were the highest as 113cm, respectively. Leaf length of SSH was high at T5. In the soybean, T2 was the highest as 17cm. Average leaf width of T2, T3 and T4 was higher than TI and T5. 2. Leaf number of T3(SSH and soybean) was higher than other treatments, Stem diameter of SSH and soybean showed the highest as 12.3mm and 8.6mrn at T5 and T3, respectively. In the SSY mean stem hardness of TI was the highest as 2.5kg/$cm^2$, but soybean was the highest at T1(8.0kg/$cm^2$) 3. Deed stubble according to move seeding date of SSH were 11.4 percentage at TI, and 3.9 percentage at T5 treatment. 4. Total dry matter yield according to move seeding date was the highest at T3 as 20,937kghq but T5 of late seeding was the lowest as 16,04Okgha(P < 0.05). 5. In the first cutting time, protein content of SSH was the highest at T3 as 9.9 percentage, but T1 was the lowest as 8.4 percentage. In the 2nd cutting, T5 was the highest as 8.7% but T1 was the lowest as 6.2%. In the soybean, T5 was the highest as 19.4% but TI of early seeding was the lowest as 16.2 percentage. Crude protein yield was the highest at T3 as 2,233.5kghq but TI of early seeding was the lowest as 1,579.7kgha (P < 0.05). As mentioned above the results, T2(may 13), T3(may 20) and T4(may 27) treatment could be recommended as the best suitable seeding date when drymatter and protein yield were considered.
