"The following were examined on hillside tea fields : the effect of root pruning on the growth of the new shoots and on the regeneration of new roots. Pruning was carried out at above 35 cm from the ground after the first crop of tea in mid May. Root pruning was carried out in September, at positions on the upslope side, the downslope side, and both sides. These three root pruning methods restrained the growth of the first crop tea in the next year. However, chlorophyll quantity and total nitrogen content were increased, and the quality of the tea-leaf was improved in all treatments. In the third year after the root pruning, there was vigorous rooting from the root pruning position on both upslope and downslope sides. It is considered that rooting was increased at the downslope side as well as the upslope side. The upslope side root pruning was considered to be practically useful. This paper presents the following results: the damage by pruning and root pruning is reduced, the workability is also considered, and the renewal of the subterranean part is attempted."
