We expect greatly going research upon the quality of agricultural products for a long time, then we have slightly investigated on this object in connection with "Sehihyojunchiyosa." Therefore, we report one part of studies on the garden radish. We examined the fact that manure-elements go without saying, each kind of nitrogen manures has remarkably effect upon the radish growth and its chemical compositions at fiftydays after sowing and harvest-time. As conclusion, the first stage of growing, the root-weight is in proportion to its volume, its specific weight to its figure-ratio and also when fertilized with one kind of manure only, radish grows good moderately, but at the last stage i.e. the harvest-time, beyond question we recognized that the excellent result was obtained in the radish quality as a matter of fact with its crop fertilizing with both quick and slow manures.
