Module VI Nutrient Deficiency Symptoms Lesson 3 Deficiency

Module VI: Nutrient Deficiency Symptoms Lesson 3: Deficiency Symptoms of Secondary Nutrients Unit 3: Magnesium Deficiency Symptoms After completing this Unit, you should be able to answer: 1. Under what conditions magnesium deficiency results in chili pepper? 2. Describe the leaf symptoms due to magnesium deficiency in chili pepper? 3. How the chili pepper plants look in magnesium deficient field?

Module VI: Nutrient Deficiency Symptoms Lesson 3: Deficiency Symptoms of Secondary Nutrients Unit 3: Magnesium Deficiency Symptoms As magnesium is not held tightly in soils, it is more susceptible to leaching losses from the root zone. Magnesium deficiency is most prevalent on sandy-textured soils, which are subject to leaching, particularly during seasons of excess rainfall.

Module VI: Nutrient Deficiency Symptoms Lesson 3: Deficiency Symptoms of Secondary Nutrients Unit 3: Magnesium Deficiency Symptoms The leaves are usually pale green to yellow in color with many brown lesions. The symptoms develop firstly on older leaves and advance upwards to younger leaves. Observe pale green to yellow leaves.

Module VI: Nutrient Deficiency Symptoms Lesson 3: Deficiency Symptoms of Secondary Nutrients Unit 3: Magnesium Deficiency Symptoms The predominant symptom is dark green veins with yellow areas between the veins (interveinal chlorosis). In some chili pepper cultivars, orange, purple, or brown lesions develop within the chlorotic tissues. Observe dark green veins with yellow areas.

Module VI: Nutrient Deficiency Symptoms Lesson 3: Deficiency Symptoms of Secondary Nutrients Unit 3: Magnesium Deficiency Symptoms Eventually these lesions expand often join together until the margins of the leaf turn orange, red, or purple in color, depending on the degree of pigmentation. When the deficiency is very severe, the margins of the older leaves turn brown, wither, and die.
