ABSTRACT
The growth and development of plants are determined by numerous factors of soils, fertilizers, water, and climate. Some of these factors are under the control of human being, but some are not. For example, rainfall, temperature, light, air, etc., cannot be controlled by the human. These factors influence the supply of nutrients in soils. Translocation of nutrients within a plant body is an ever-continuing process. In this regard, there is a considerable difference in the mobility of different nutrients. Nitrogen is very mobile in plant in comparison to phosphorus, potassium and magnesium. Nitrogen (a high mobility nutrient) deficient plants have yellow colored lower leaves and green upper leaves but nutrients with weak mobility such as phosphorus, potassium and magnesium deficient plant produce symptoms on newer leaves and growing points.
