Description
A field experiment was carried out in 1989 and 1990 to determine the effects of dead material (length 15 cm and 30 cm), date of burning (21 February, 2 March, I I March and 20 March) and a non-burning control treatment during eacly spring on grass growth, yield, and nutritive value in existing pasture dominated by orchardgrass (Dactylis glomerata L.). On average burning treatments increased the soil surface temperature and the 10 cm soil depth temperature by S.5°C and 2.8°C respectively. A little burning damage was present after the burn on 20 March. However, burning, date of burning or length of dead material did not significantly affect annual yield. As the date of burning was delayed, crude protein content was increased, but nitrogen-free extract content was decreased. No diseases and insect pests were observed. In conclusion, grassland burning in early spring cannot be recommended in Korea, as it does not increase forage productivity, and gives rise to the danger of forest fires.
