Abstract

Three rates of nitrogen, phosphate and potassium were applied to a old tobacco Hyangcho for the establishment of the optimum rate of fertilizers for Growth and chemical component. 1. The rate increament of nitrogen and potassium increased tobacco growth, but the effect of phosphate was non-significant between rates. 2. The contents of total-nitrogen and total-alkaloid in the leaf increased with increase of nitrogen rate while the effect of phosphate and potassium were negligible.
