For the purpose of using the guideline to evaluate the grassland based on the botanical composition, a valuation figures which were expressed of nine division scale from 0, very poor to 8, excellent were given to the each , grassland species. At first, a figure was given to the 14 1 herbage plants at the grassland in Korea. Fodder value of the grassland was calculated from these valuation figures of the different species and the DM percentages of each plants which was got by analysis or estimation, were only to be multiplied by the different valuation figures and then the sum of these products divided by hundred. It is suggested that the fodder value of the grassland is not only possible to express the botanical conditions of various experiments in some simple figures, but also compare with different types of grassland at the same time.
