1. The effect of foliar spray of urea on the tea cutting was researched from 1953 to 1954. As the result of this experiment, the living percentage, the number of new root and leaf, the length of new shoot and the weight of new shoot were increased, but the number of flower-bud was decreased by the foliar spray of urea. And the analysis of variance indicated that these tendencies were recognized highly significant in the pre-treatment, namely in the spray on the preparing shoot of mother plant before cutting.<BR>2. The growth of shoot after spraying was researched. The following results were obtained that the dimension of leaf and the internal tissue were not varied, but the deveo!pment of new shoot was obstructed by the foliar spray. The chemical analysis of the leaf and stem was also carried out. The total nitrogen and the soluble nitrogen were increased, and the tannin was not varied, but the crude fibre was decreased by the foliar spray.
