| Abstract: | The field test for studying the effects of nitrogen application on agronomical characters, leaf quality and yield of flue-cured tobacco was conducted in 2004. The result showed that applying 30%0 of total amount of nitrogen fertilizer as top dressing at 20 days after trans-planting obtained the higher quality of upper and lower leaf; the proportion on high-middle grade leaves amounted to 87.5% ; the yield and output value per 667m^2 reached 198.8 kg and 1681 yuan separately, showing very significant difference with the other treatments. |
