This is a signal that the corn is not getting enough water , and it can lead to scrubby increment , reduced yields , and even death if not addressed .

Lack of water is also a major cause of nutrient deficiencies in the industrial plant , as the roots are unable to take up enough of the of the essence nutrients from the soil . to boot , dry soil can lead to high degree of soil pH , which can make the leaves to become yellow . With wry stain , the plant is ineffective to enter the necessary nutrient and pee to remain healthy , lead to yellowed leafage .
Root rot
Root rotis a common job that can cause yellow corn whisky leave . rootage rot is due to a mixture of different fungi , such as Pythium and Phytophthora spp . These fungus infect the corn plant life ’s root scheme , attack the roots , stalk and leaves . As the fungi spread , they consume the nutrients , pee and O needed for the plant to survive , leading to yellowing and wilt . In utmost suit , root rot can cause the plant to crumble and die . The damage to the roots makes it difficult for the plant to soak up indispensable nutrients , lead to yellow , stunted growth and leaves .
