Role and deficiency symptoms of potassium in Mango

1. Role and deficiency symptoms of potassium in Mango

2. Role and deficiency symptoms of potassium in Mango Introduction Supply of potassium in a balanced manner is very important for improving soil health and plant nutrition. To maintain sustainability of soil and growth of the tree, it is therefore important to supply potassium partially through inorganic and partially through organic sources. Thus, it is important to use chemical fertilizers judiciously to get higher yield without affecting soil health. Before adapting integrated nutrient management practice in mango, it is important to know the role and deficiency symptoms of potassium on mango. Therefore, in this RLO you will learn the role and deficiency symptoms of potassium on mango.

3. Role and deficiency symptoms of potassium in Mango Role of potassium in Mango • The quality of the fruits, especially coloration of the skin, aroma, size, and shelf life, is improved when there is adequate K. • K also increases the ability of the plant to withstand stress conditions, such as dry, cold, salinity and attacks of diseases and pests.

4. Role and deficiency symptoms of potassium in Mango Role of potassium in Mango • It is essential for formation and synthesis of proteins and CHO in plants. • It helps in formation of stiff stems and healthy root system. • Also promotes cell formation-highly mobile in plants. • The quality of the fruits, especially coloration of the skin, aroma, size, and shelf life, is improved when there is adequate K. • It counteracts the adverse effects of excessive nitrogen.

5. Role and deficiency symptoms of potassium in Mango Deficiency of potassium in Mango Potassium deficiency symptoms occur in the oldest leaves as small red spots, irregularly distributed. The leaves are smaller and thinner than normal. With a more pronounced shortage of K, the spots coalesce and the leaf suffers necrosis along the edges. Leaf necrosis on older leaves

6. Role and deficiency symptoms of potassium in Mango Deficiency symptoms • The leaves fall only when they are completely dead. • K deficiency caused die back which proved fatal to the plants. • Tip burn and marginal necrosis are the main symptoms of K deficiency. Marginal necrosis

7. Role and deficiency symptoms of potassium in Mango Deficiency symptoms • Scattered yellow spot, necrotic areas along the margin of small thin leaves. • An excess of K may cause an imbalance in the levels of Ca and Mg, which also causes browning along the edges and apex of the older leaves. Potassium deficiency on older leaf

8. Role and deficiency symptoms of potassium in Mango Let Us Sum Up Potassium is a very important mineral for the proper function of all cells, tissues, and organs in the plant. The main role of potassium is to provide the appropriate ionic environment for metabolic processes in the cytosol, and as such functions as a regulator of various processes. Plants require potassium for protien synthesis and for the opening and closing of stomata. Potassium also functions in other physiological processes such as photosynthesis, protien synthesis etc. Deficiency of potassium can be achieved in the shorter term by adding potassium-specific fertilizer, like potassium sulphate, potassium chloride etc.
