The whole-quantity fertilization techniques using nursery boxes, of paddy rice 'Hinohikari' in mountainous areas were examined. 1) In the nursery phase, root spreads of seedlings cured at 2-8cm height stage were equivalent at transplantation time. 2) Failure rates of seedlings after transplantation, cured in 2-6 cm height were almost the same as the habitual cultivation. But, seedlings cured in 8cm height were spindly, and lodging rates after transplantation increased. 3) The whole-quantity fertilization using sigmoid 120-day type had the following features, compared with habitual fertilization. (1) The numbers of stalks at the growing period and panicles per square m were equal or small a little. (2) One panicle number of grains was slightly large. The number of grains was equal or slightly large. (3) The brown rice weight was slighty heavy or equal. The inspection grade was similar.
