Estimation of fertilizer nitrogen requirement for average rice yield in Japanese paddy fields
Soil Science and Plant Nutrition, 2002 Abstract The fertilizer N requirement (Nf500) for average rice yield (500 g m−2) in the paddy fields of Japan was estimated. The Nf500 of a paddy field is defined as Nf500 = Nf (500 - Y n0) / (Y - Y 0), where Y is the grain yield of the NPK plot, Y 0 is the grain yield within the PK plot, and N f is the rate of N application in the NPK plot. Nf500, was
