Symptoms of Magnesium deficiency in Moong

Symptoms of Magnesium deficiency in Moong

Due to a lack of magnesium, the leaves of the plant turn yellow, but the veins remain green. The older leaves of the plant begin to fall. In some plants, the edges of the leaves begin to curl upwards. Plant growth and root development are reduced. Brown or black spots may appear on plants suffering from magnesium deficiency. Eventually, The plant withers and the twigs become weak and become sensitive to fungal diseases. Immature leaves fall off. The micronutrient magnesium is a main component of chlorophyll in plant leaves. Crops require very small amounts of magnesium nutrients. Magnesium plays little to no role in plant growth and development. But its deficiency makes more difference in the quality of fruits, flowers and grains. This is the reason that its deficiency is visible in the standing crop of moong. Know the level of magnesium through a soil test. Then apply the amount of magnesium to the crops, based on the results of the soil test.
