Water for crop growth were supplied by irrigation in protected cultivation and these are accumulated in the soil and utilized forcrop evapotranspiration. The study for analyzing soil moisture characteristics is necessary for adequate irrigation water and soil watermanagement in protected cultivation. Soil moisture content, irrigation water quantity and meteorological data were monitored to analyzesoil moisture increment and extraction characteristics in terms of soil layers and cucumber crop growth stages. In first cropping period,the total amount of irrigation water was 5.07 mm/day, soil moisture increment was 4.82 mm/day and soil moisture extraction was 5.56mm/day. In second cropping period, the total amount of irrigation water was 4.82 mm/day, soil moisture increment was 4.65 mm/dayand soil moisture extraction was 4.73 mm/day. Soil moisture extraction rate from 0 to 75 cm is 90.3 % in first cropping period and79.1 % in second cropping period. The majority irrigation water were consumed in root zone, however, about 15 % of soil moisturewere losses by infiltration in lower soil layer. Soil moisture extraction and extraction pattern of cucumber crop calculated in this studycan be utilized as a basic data for irrigation water management in protected cultivation.
