This experiment was Carried out to determine the effect of amount of fertilizer applied and cutting dates on the growing characters, yield and chemical composition of Russian Comfrey, and to evaluate the adaptability under our conditions. The Result obtained are as follows: 1. Russion comfrey can be cut three times during planting year, while during second year it can be cut seven times from the end of April to October. 2. It was observed that length of plant and size, of leaf during midsummer was more longer and larger than spring and autumn, and emergence of bolting was found more on May than any other months. 3. Yield of Russion Comfrey was less during planting year than second year(8,000 ㎏/10a). In seasonal distribution of green yield, it was found the Russian Comfrey was more yielded during midsummer than spring and autumn. 4. Chemical Composition of Russian Comfrey is as following; $lt;표생략$gt; 5. It was indicated that the effect of manure as a fertilizer was more obvious than comercial fertilizer. As the result of experiment it is concluded that the Russian Comfrey is a well adaptable forage crop under our condition and hoped it is a good forage crop for farm animals.
