Abstract
An automatic fogculture system for year-round rice production was developed. Its purpose was to reduce natural and environmental damages on rice production and farmland. Two rice cultivars, Koshihikari and Harebare, were grown from Mar. 12, 1992 to Aug. 24, 1992. Because the amount of sunlight was decreased to one-third of normal light intensity, growth and development of the two cultivars was very uneven. Yield of Koshihikari which was the better developed of the two, was 808 kg/10a. The yield of Harebare, which did not grow well, was 23 kg/10a. If this system was given enough sunlight and had a controlled temperature, a higher yield may be possible.
