Tomato plants (cvs. Seokwang and Momotaro) were drip-irrigated at three soil moisture levels (-16 ㎪, -32 ㎪, and -50 ㎪) during spring or winter season, respectively. In spring season, the rate of marketable fruit and marketable yield were increased as soil moisture was high. The proportion of cracking fruits appeared high at -50 kPa, and was higher in ´Seokwang´ than in ´Momotaro´. In winter season, the rate of marketable fruit was not dependent on the soil moisture, but was higher in ´Momotaro´ than in ´Seokwang´. Marketable yield was the highest at -50 ㎪. Blotchy ripening fruits were observed only in ´Seokwang´, but were not dependent on the soil moisture. Chlorophyll content was the highest at -50 ㎪. Total nitrogen content of leaves was the highest at -50 ㎪, and higher in ´Seokwang´ than in ´Momotaro´.
