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.
