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. |
| 1440090 |
potassium deficiency |
|
Symptoms of K deficiency in tobacco first appear on lower or middle leaves and move up the plant as the problem becomes more severe. The distinguishing characteristic is mottled or "scorched" appearance that develops at the tips and along the edges of leaves. In the early stages, mottles are pale green or yellow, followed by the development of brown or dead centers. As the deficiency increases, mottles tend to run together and the dead areas fall out resulting in ragged leaf margins. Because the remaining green areas continue to grow, leaves often develop a crumpled or puckered appearance with edges cupping downward. K deficiencies appear to be encouraged by dry weather. Also, tobacco is usually less stunted by a deficiency of K than by a deficiency of either N or P. |
| 1440088 |
nitrogen deficiency |
|
The most easily observed symptom of N deficient tobacco is the yellowing (chlorosis) of the leaves due to reduced chlorophyll levels. The yellowing begins in the lower leaves and moves upward as the deficiency increases. Under severe deficiencies, the entire plant will show a decrease in normal green color with bottom leaves changing from a light yellow to a brown or dead appearance. This drying-up or "firing" appearance may also result from water shortages during drought conditions. N deficient plants are usually normal in shape but less than normal in size. Leaves are generally smaller, thinner, and more upright on the stalk than when N is adequate. Waterlogged or flooded soils and turning under of thick stands of non-leguminous crops or sods without sufficient time for decomposition are conditions often associated with N deficiencies. |

Magnesium (Mg) deficiency |
| 1402097 |
magnesium deficiency |
|
Magnesium (Mg) deficiency, sometimes called "sand drown," occurs primarily on sandy soils during seasons of excessive rainfall. The first symptom of deficiency is loss of green color from lower leaves. On individual leaves it begins at the tips and margins and proceeds toward the base and center. Interveinal tissues become chlorotic while veinal areas remain green (photo). In extreme cases, lower leaves turn almost white and chlorotic symptoms progress to higher leaves. Mg deficient leaves rarely develop necrotic spots. It may occur at any stage of growth but occurs most often following rapid growth during the leaf production phase (4-8 weeks after transplanting). High rates of K and/or Ca on low Mg soils may enhance Mg deficiency. |
| 1402099 |
manganese deficiency |
|
Manganese (Mn) deficiency occurs primarily on overlimed soils (pH above 6.2) which are also low in available Mn. A deficiency of Mn causes flecking on the lower leaves similar to that of weather fleck. In contrast to weather fleck, Mn deficient plants are stunted, and affected leaves are more chlorotic and eventually take on a "ragged" appearance as the flecks coalesce and dead tissue falls out. Subsequent growth usually appears normal, but flecking may advance to middle and occasionally to upper leaves if root development is restricted. |
| 1402098 |
sulfur deficiency |
|
Sulfur (S) deficiency is more likely on deep, coarse soils with low levels of organic matter when little or no fertilizer S has been applied. Since S may accumulate at lower soil depths, deficiencies normally occur during early growth before extensive root development. In contrast to N, the first symptom of S deficiency is a mild chlorosis of the upper leaves and bud. Unless the deficiency is alleviated, the entire plant will become chlorotic and flowering may be delayed. Another distinguishing difference between N and S deficiency is that the lower chlorotic leaves of S deficient plants are not lost by "firing" unless nitrogen is also deficient. Crops deficient is S show very little greening response to additional N until the S deficiency if corrected. |
| 1402100 |
boron deficiency |
|
Boron (B) deficiency is rare but is more likely to occur at soil pH above 6.2, especially on sandy soils following periods of high rainfall and/or rapid growth. Initially, the bud leaves become light green and distorted. In advanced stages, the terminal bud dies and the remaining leaves become abnormally thickened and tend to curl downward. Lower leaves become turgid and brittle as indicated by breaking of the midrib, which may cause leaf drop. The tissue of the broken midrib may be darkened. |
| 1402092 |
nitrogen deficiency |
|
Nitrogen (N) deficiency may result in retarded growth and leaves with a pale green color. Lower leaves yellow prematurely, are smaller, and tend to "fire" or dry up. The stalk is short and slender, leaves tend to be more upright than normal, and flowering is delayed. Premature flowering may result if certain stresses such as low temperatures or extremeness in soil moisture interfere with N uptake and use. Symptoms of deficiency usually appear first on the sandier areas of a field after excessive rain or irrigation even when adequate N fertilizer had been previously applied. |
| 1402095 |
potassium deficiency |
|
Potassium (K) deficiency causes slight mottling and brownish-yellow spots on leaf tips. Later there are brownish-yellow spots on leaf tips. Later there are brownish-yellow spots along leaf margins that become necrotic and fall out, leaving a ragged appeareance. Leaves may be puckered, with the tips and margins curled downward. Symptoms first appear on lower leaves in young plants and upper leaves on older plants. Symptoms are more acute on rapidly growing plants and may be accentuated by excess N. Excess K does not causes visible symptoms. |

calcium deficiency |
|
Ca deficiency in burley tobacco is not common but sometimes occurs when soil exchange capacities and/or Ca saturation levels are low. Such conditions are most likely to occur in sandy soils with low pH. Ca deficiency symptoms first appear in the upper or youngest leaves because Ca is immobile within the plant. Typically, symptoms begin in the bud with the development of a pale green color, followed by rolling and downward curing of the new leaves. As the deficiency becomes more acute, dead or necrotic areas develop at tips and along edges of leaves. Under extreme deficiencies, the terminal bud eventually dies. Lower and middle leaves of Ca deficient plants may develop a darker a darker than normal green color. |

phosphorous deficiency |
|
Delayed growth, particularly in the early season, is typical of Phosphorus (P) deficiency. Plants may be dark green in color if N levels are adequate, and leaves may be narrower than normal. Small, necrotic spots may appear on the lower leaves when deficiency is severe. Due to generally adequate levels of P in previously cropped and well-fertilized soils, deficiencies of this element are rare and often temporary. Photo shows plants in a low P soil on right. P shortages may be induced if root growth is restricted. High soil or fertilized if root growth is restricted. High soil or fertilizer P levels may result in more rapid early growth but not increased yields. As the root system expands, growth differences between various P levels become less apparent. |

nitrogen deficiency |
|
Nitrogen (N) deficiency; The two most common symptoms of N deficiency in tobacco seedlings are: (1) leaves develop a light or pale yellow color, and (2) plants become stunted, showing little growth and vigor. Similar symptoms may develop from a lack of water during dry weather. N deficiency in tobacco seedlings is not common if recommended amounts of N are properly applied to plant beds. However, excessive rainfall may create the need for additional N. Also, the use of ammonium or organic forms of N on plant beds fumigated in the spring may result in N deficiency. |

calcium deficiency |
|
Calcium (Ca)deficiency seldom occurs under field conditions, but some varieties cannot supply sufficient Ca to buds and young leaves during periods of rapid growth even though soil Ca is adequate for normal growth of other varieties. Initially, Ca deficient buds are twisted with downward curling of leaf margins and downward hooking of leaf tips. As leaf expansion continues, these symptoms become more pronounced, with separations of margin tissue which give the leaf a scalloped appearance. Tip and margin tissues become chlorotic and tips cease growing, giving the leaf a stubby appearance. Ca deficient leaves are thicker and sometimes greener than normal leaves. Symptoms become progressively less pronounced on older leaves and seldom occur at the lower stalk positions. |
