Knowledge of nutrient content of tobacco and of removal of nutrients from soil is essential to developing sound fertilization practices for tobacco. Quantities of nutrient elements taken·up by tobacco vary widely. This is because of variations in variety, soil fertility level, fertilizer application, soil moisture, plant population, and other environmental and cultural factors . We conducted the present study to determine the effects of applied N and suckering practice on the content of mineral elements in certain plant parts of burley tobacco.
