The names of five different deficiency symptoms are: (a) Chlorosis: It is the loss of chlorophyll leading to the yellowing of leaves. It is caused by the deficiency of elements N, K, Mg, S, Fe, Mn, Zn and Mo. (b) Necrosis: It is the death of the tissue particularly the leaf tissue and appears due to the deficiency of Ca, Mg, Cu, K. (c) Inhibition of cell division:  Inhibition of cell division which affects the general growth of the plant and elongation of parts like roots is caused because of the deficiency of N, K, S, Mo. (d) Delay in flowering: Some elements like N, S, Mo delay flowering if their concentrations in the plant are low. (e) Stunted plant growth: Stunted growth occurs due to deficiency of N, P, Ca.
