In order to establish the management technique for the environment of strawberry rhizosphere, soil moisture conditions were adjusted to three different levels, wet (40~43% WHC), standard (37~38% WHC) and dry(30~35% WHC), and soil temperatures were controlled by vinyl mulch and electric heating of soil. When the soil moisture was adjusted to PF 1.2~1.4(40~43% WHC) during 2 weeks before harvesting of fruits and then it was maintained at pF1.6~1.8(37~38% WHC) during the following period, it was observed that the higher yield with good quality of strawberry fruit was obtained constantly and efficiently.
