NFT system of strawberry with semi-forcing culture were tried in three types of beds. Generally, there are very few differences in quality and quantity between soil culture and NFT of strawberry with forcing culture. But, on average, we could yield more than 600 g per each plant which is twice as much as the yield of soil culture.<BR>Observing the state of plant growth carefully, pH and EC of nutrient solution were controlled very differently from those of usual NFT culture. And by comparing the plant growth of each beds, it was cleared that the space between planting panels and surface of nutrient solution had very significant meanings. Namely, forms of rooting were different diffinitely according to the spaces. The spaces of several ten millimeters were considered very effective for primary rooting. But the spaces had a tendency to cause ill-balances between vegetative and reproductive growth. So cultivation with well-balanced forms of primary and secondary rooting are demanded.
