What deficiency causes marsh spot in peas?

✅ EXPLANATION:: Marsh spot in peas is caused by manganese deficiency. Manganese is essential for many vital plant processes, including photosynthesis, respiration, and nitrogen metabolism. When soil is deficient in manganese, plants are unable to properly perform these processes, leading to marsh spot. Symptoms of Marsh Spot: Brown or black spots on leaves Spots enlarge and may merge into larger patches Spotted leaves may dry and fall off Plant growth may slow Yield may decrease Preventing Marsh Spot: Test the soil for manganese levels If soil is deficient, apply manganese sulfate or manganese oxide fertilizer Practice crop rotation Select disease-resistant varieties
🔹 Magnesium (Mg): Magnesium is a crucial component of chlorophyll, which is essential for photosynthesis. Magnesium deficiency can cause leaves to turn yellow.
🔹 Boron (B): Boron is essential for cell wall structure and function. Boron deficiency can stunt plant growth and deform fruits and seeds.
🔹 Copper (Cu): Copper is involved in many vital plant processes, including photosynthesis, respiration, and nitrogen metabolism. Copper deficiency can slow plant growth and pale leaves.
