Abstract

This study examines changes in rice planting technology used by the Yoshino family during the forty-one years from KyOwa 2 (1802) to Tempo 13 (1842). It looks at the characteristics particular to each of three time periods, delineated by the degree of improvement in drainage conditions of the Sakagawa River. Although the impact of climatic fluctuations, which peaked in 1836, was felt during this period, the techniques of cultivation continued to intensify. The various aspects of the intensification of the techniques of cultivation are outlined below: i A complete shift from direct Toumomi rice seeding in submerged paddies to cultivation by setting seedlings. ii A decrease in the number of transplant seedlings needed per unit of planting area. iii A decrease in the number of days needed for soaking rice seeds. iv An improvement in the quality of seedlings and a decrease in the number of days needed for using rice seedling beds due to the amelioration of fertilization in rice seedling beds. v A shift towards earlier transplanting. vi An increase in the length of the growing period in paddy fields, which in turn provided for an increase in the quality of such growth. vii A shift in makeup from an emphasis on early Toumomi rice varieties to early and medium maturing varieties. As a result of the intensification of these techniques of cultivation, which proceeded primarily in line with a reduction in the number of transplant seedlings needed per unit of planting area, the Yoshino family benefited from significant increases in productivity from 1837 onwards.
