In this study, we aimed to examine the effects of hole-mulching culture on the growth circumstance and production of plum. As a result of three years’ experiment, the following effects of mulching were clarified. 1) The soil moisture content of hole-mulching plot increased greater by about 25% than the mulching plot due to the penetration of rainwater from multi-hole. 2) The evaporation from soil surface of hole-mulching plot was suppressed to about one-third of non-mulching plot. 3) Soil temperature of hole-mulching plot tended to be lower than mulching plot. 4) The production of hole-mulching plot was higher than non-mulching plot, but slightly lower than mulching plot. 5) The variation in individual weight of fruit of hole-mulching plot was as small as mulching plot and smaller than the non-mulching plot, and the percentage of fruits less than 15g with low commercial value was less than 10% of total fruits.
