The consumption of three sorts of ions (Ca<SUP>2+</SUP>, K<SUP>+</SUP> and NO<SUB>3</SUB><SUP>-</SUP>), EC and pH were continuously measured during the growth period of Muskmelons cultivated in NFT.<BR>The diurnal courses in the consumption of Ca<SUP>2+</SUP>, K<SUP>+</SUP> and NO<SUB>3</SUB><SUP>-</SUP> fluctuated periodically. The negative consumption of ions was observed. This was notable during the night in three sorts of ions. These ion consumption was not correlative to the quantum flux density during the first half of vegetative stage but during the pollinating stage in which the ion consumption became high, it was corresponded to quantum flux density. The consumption of the water caused by the transpiration was in good coincidence with the quantum flux density in every growth stages. The EC decreased until the first half of the developmental stage of fruit but after that stage, it increased. The pH decreased in every growth stages.<BR>The daily patterns in the consumption of Ca<SUP>2+</SUP> was small until 15 days after planting but after that time, it increased and reached to the maximum value on 32-37 days after planting. The consumption of K<SUP>+</SUP> was also small until 18 days after planting although it increased temporally on 6 days. Then, it increased rapidly and attended to the maximum value on 28-37 days after planting. The consumption of NO<SUB>3</SUB><SUP>-</SUP> increased from 6 days after planting but decreased temporally on 16-17 and 21-25 days. Then, it increased rapidly and attended to the maximum value on 28-30 days after planting. The consumption of the water increased with the growth.
