Tobacco deficient in P will be slow-growing, stunted, late maturing, and display a dark to very dark green color throughout the plant. Leaves tend to be more erect, closer together, shorter, and narrower than those receiving ample P. Temporary symptoms that have been reported as indicating P deficiencies include plants wilting during mid-day and occurrence on lower leaves of brown (dead) spots that are sometimes surrounded by a pale yellowish-green color. P deficiency symptoms are perhaps less evident and more difficult to recognize in the field than symptoms produced by deficiencies of any other essential plant nutrients. Therefore, soil and/or plant analyses are often necessary to verify suspected P deficiencies.
