Experiments for trying to extend cropping season of rice were conducted during 1984-1987, under the assumption that the transplanting time was between the third and the sixth pentad of June and its expected yield was 540 kg/10a or more. 1) Maturing stage obtained was from fifth Oct. to fifth Nov. by the combination of varieties and seedling size. 2) For the transplanting in the early period of June, it was necessary to apply top-dressing in the middle stage of the growth. 3) For the transplanting late variety in the sixth pentad of June, it was better to transplant big seedling. 4) In the southern part of Fukuoka prefecture, late transplanting is possible, especially for late variety, because the heading date delayed about 5 days in Chikugo-shi than Chikushino-shi
