This experiment was conducted to obtain some informations on the effects of number of leaf harvest and time to agronomic characters and grain yield in perilla. For the experiments perilla seedlings of 40days old were transplanted on June 20, July 20 and August 20 in 1988, and leaf harvested at 30. 40. 50 and 60 days after transplanting, respectively. The following results were obtained from the experiments. In the case of the fully developed leaves were harvested, culm length were decreased by more harvests and by the later harvests. However culm diameter, number of nodes and branches were little influenced by the leaf harvests. Number of clusters, weight of 1,000 grain and grain yield were significantly influenced by the number of leaf harvest and time. As the above results, considering the grain yield, leaf harvest would be available in the case of once or twice at the early growing stage.
