Deficiency in Plants
Deficiency is the lack of something. Plants work in quite the same way. They too need nutrients to sustain themselves like every other living being.They get most of these nutrients from the soil. But if the supply of an essential element becomes limited, plant growth is stunted or in other words, plant growth becomes retarded. Critical concentration is the term used for the concentration of an essential element below which plant growth is retarded and that element is said to be deficient in the plant.
The absence of any element necessary for the sustenance of that particular plant will lead to the morphological changes in the same plant. And this change is an indication of a deficiency. Of course, if the deficient element is provided to the plant in good time, the symptoms of deficiency disappear. However, if the process is delayed, eventually the plant will die. Similarly, even in your case if you continue to deny the water by yourself, it will result in your demise too. Another thing to note is that the symptoms tend to appear first in the older tissues of the plant and then the younger ones when the elements are relatively mobile, like nitrogen. While the symptoms tend to appear first in the younger tissues when the elements are relatively immobile and are not transported out of the mature organs.
The deficiency symptoms are varied and include, stunted plant growth, premature fall of leaves and buds, yellowing of leaves, etc. These symptoms could be caused due to the lack of elements like N, K, Mg, S, Fe, Zn, Mo, etc.
It must also be kept in mind that different plants respond to different deficiencies, differently.
