버어리종 담배의 시비량이 수량 및 품질에 미치는 영향

Three levels of nitrogen, phosphate and potassium were applied to tobacco for the establishment of the optimum rate of the fertilizers for yield and quality. 1 . The rate increment of nitrogen and potassium increased tobacco growth, but phosphate were non - significant between rate. 2. The contents of total-nitrogen and total-alkaloid in the leaf were increased, with the increase of nitrogen rate while the effect of phosphate and potassium were negligible. 3. The yield and quality of the tobacco were increased with the increasing rate of nitrogen and potassium fertilizer but phosphate should little difference.
