Which of the following is the cause of Black Heart Potato?

✅Explanation:
– 
-Black Heart is a physiological disorder that affects potatoes, causing darkening and necrosis in the center of the tuber, giving it a black appearance. The disorder is primarily caused by oxygen deficiency in the tuber.
– 
-1) Nitrogen deficiency is not directly associated with the development of Black Heart in potatoes. Nitrogen deficiency can lead to other growth and yield issues, but it is not the main cause of Black Heart.
– 
-2) Carbon deficiency is also not a known cause of Black Heart in potatoes. Carbon deficiency can affect plant growth and photosynthesis, but it does not directly contribute to the development of Black Heart.
– 
-4) Manganese deficiency is not a recognized cause of Black Heart in potatoes. Manganese deficiency can result in other symptoms, such as yellowing and interveinal chlorosis, but it is not linked to the development of Black Heart.
– 
-Black Heart in potatoes is primarily related to improper storage conditions or handling practices that lead to reduced oxygen availability to the tubers. Factors such as excessively high storage humidity, poor ventilation, compacted storage piles, or long-term storage in sealed containers can contribute to oxygen deficiency and the subsequent development of Black Heart.
