This experiment was conducted to find out the optimum fertilization level and topping depth for flue-cured tobacco in the fields which chinese cabbage and red-pepper were cultivated. The fertilization level were 0, 25, 50, 75kg per l0a as tobacco compound fertilizer and the topping depth were topping floral axis, topping under the second leaf frp, axos and the fourth leaf from floral axis. In order to product good quality tobacco leaves in the fields which vegetables were cultivated, the optimum amount of tobacco compound fertilizer was recommended 50-75kg per l0a for the field of the chinese cabbage cultivated. and 75kg per l0a for the field of the red-pepper cultivated. The optimum topping depth was desirable at topping under second leaf from floral axis for good leaf quality in chinese cabbage and red-pepper cultured field.
