Of 6 applied soil, tendencies were as follows : (1) Production of mulberry leaves (Morus alba), from each fertilized plot, was various according to the kind of soils. With an increasing supply of N the production was more increased, but the supply of P_2O_5 alone did not increase the production of K_2O, the same tendency was, when it was applied alone in increasing amount. (2) N and P_2O_5 had to be applied in proper in order to increase the production of mulberry leaves. K_2O seemed to have the same tendency. We came to the decision that the fertilization of mulberry tree has to be schemed depending upon the suitable ratio of P_2O_5 or K_2O to basal applied N.
