This study was undertaken to clarify the effects of rice transplanting date on the heading time and the harvest time, by using 3- or 4-day seedling of cv. Sasanishiki for 3 years (1989-1991).Transplanting dates, from late April to middle May, caused some variation of heading time and could spread the period of desirable harvest time. And the highest yield produced from the 3- or 4-day seedling at each transplanting date was about equal to or higher than the average yield in the same area. We, therefore, have judged that transplanting the 3- or 4-day seedling in this period will be possible from practical point of view.Based on these results, we suggest a pattern of transplanting working system using the 4-day rice-seedling. Treating the work from seeding to transplanting as 1 unit, a farmer will be able to manage 12 units in 30 days from April 20th. That means he can cultivate paddy rice of more than 12ha under his present farming facilities.
