摘要：

Nutrient deficiency disorders often manifest unique symptoms and vary in critical nutrient ranges depending on species and type. Understanding and recognizing nutrient disorders for different types of tobacco (Nicotiana tabacum L.) is important for maintaining quality and yield. Burley and flue-cured tobacco account for over 90% of all tobacco produced in the United States, and thus, were grown in this study to investigate the effects of macronutrient deficiencies. Tobacco plants were grown in silica sand culture, and control plants received a complete modified Hoagland's all-nitrate solution, whereas nutrient-deficient treatments were induced with a complete nutrient formula withholding a single nutrient. Plants were automatically irrigated, and the leached solution was captured for reuse. A complete replacement of nutrient solutions was done weekly. Plants were monitored daily to document and photograph symptoms as they developed. A description of nutrient disorder symptomology and critical tissue concentrations are presented.
