The soil properties, plant growth characteristics and nutrition necessary to produce high rice yields were investigated at (a) Furukawa (Gifu Prefecture), a hilly, cold region and at (b) Ishinden (Mie), a low-lying, warm region, in 1967-9. Yields were higher (8.97-9.731 paddy/ha) at (a) than at (b) due to increased ripening and 1000-grain weight. N, P and Mn contents and Mn: Fe ratio were highest at (a), while Si contents were higher at (b) up to heading, and were similar at maturity.
