In order to find out the effect of different grazing system at early stage of newly established pasture on the botanical composition, seasonal herbage distribution and total dry matter yield, the treatment used were (A) lenient grazing-intensive grazing-followed by cutting, (B) intensive grazing-intensive grazing-followed by cutting, (C) lenient grazing-followed, by cutting (D) intensive grazing-followed by cutting. The results obtained are as follows: 1. Main species affecting total herbage production was Dactylis glomerata and the species holded from 50 to 58 percent of total DM according as treatments applied while, in terms of seasonal herbage distribution DM yield at second and third harvest formed 55 to 65 percent of total DM yield. 2. The influence to botanical composition of the pasture from grazing was not permanant, but temporary in this kind of treatment. Such a result was proved by the fact that, in spite of different grazing treatment, botanical composition after the third harvest was almost same as the first. 3. Intensive grazing at early stage of newly established pasture (treatment B. D) suppressed the growth of Italian ryegrass, resulting temporarily in a decrease in herbage production, but this treatment favored the regrowth of Dactylis glemerata so that this result made contribution to an increase in terms of total DM yield. 4. The total DM yield was increased in order of treatment B, D, A and C. Above results suggested that grazing at early stage of newly established pasture (next year spring) raise the rate of the botanical composition of main species such as orchard grass and tall fescue when Italian ryegrass is included in seed mixture.
