Abstract

A field experiment was conducted to evaluate growth characteristics, forage production and crude protein yield according to cutting time of Soghum ${\times}$ Sudangrass Hybrid, and decide ideal harvesting time for use of soiling and silage. Experiment design was arranged with 7 different treatment T1(150 m), T2(200 cm), T3(boot), T4(heading), T5(milk), T6(dough) and T7(yellow stage), as a randomized block design. The results were as fellows : Cutting times of utilization during the course of a year was 4 times at T1 and T2, 3 times at T3 and T4, and 2 times at T5, T6 and T7. Accumulative plant length was the highest at T2(666cm), but T3 was the lowest as 402 cm. Mean Leaf length was the highest at T5(82.1 m) and lowest at T7(T1.8 m). Mean leaf width was the highest at T2 and lowest at T6. Stem diameter was orderly ranked as T3(10.7 mm)>T1(9.5)>T2, T5(9.3>T6(8.9)>T7(8.6)>T4(8.5). Stem hardness was orderly ranked as $T7(3.2 kg/cm^2$>T5, T6(2.3)>T3, T4(1.5)> T2(0.6)>T7(8.6)>T1(0.5). Mean of leaf number and leaf ratio was the highest at $T3(8.1\%)$ and $T2(45.3\%)$, respectively. The highest yield of fresh and dry matter was obtained at T4 and T6 as 113,246 and 24,249 kg/ha, respectively(P<0.05), and e lowest at T7 and T1 as 82,675 and 13,006 kg/ha, respectively(P<0.05). Crude protein yield was highest at T6(1.456 kg/ha) and lowest at T3 as 1,189 kg/ha. As mentioned above the result T1, T2 and T3 could be recommended as use of soiling, and T5, T6 and T7 as silage.
