Zinc (Zn) deficiency in corn causes interveinal, light striping or a whitish band beginning at the base of the leaf and extending towards the tip. The margins of the leaf, the midrib area, and the leaf tip usually remain green. Plants are stunted because internodes are shortened.Click to see full answer. Considering this, what does nitrogen deficiency in corn look like?Nitrogen deficiency symptoms initially appear as a “V” shaped yellowing on lower leaves that begins at the tip and progresses toward the stalk. Nitrogen deficiency can also cause ears with tip-back, poor kernel set, and shallow kernel development.Also, what does sulfur do for corn? Sulfur is an essential nutrient for corn growth, and a critical nutrient to make required proteins. Total uptake of S in a corn crop ranges from 0.1 to 0.12 pound S per bushel of corn produced. In this regard, why is my corn light green? Corn plants turn pale green to yellow because they have not been able to absorb enough nitrogen. When soils are cool and wet, the plant cannot efficiently collect nitrogen from the soil. The good news about yellow corn is that the plant will grow out of it. These plants will green up after a few days of sun.What are some signs of nutrient deficiency in plants?Symptoms caused by nutrient deficiencies are generally grouped into five categories: 1) stunted growth, 2) chlorosis, 3) interveinal chlorosis, 4) purplish-red coloring and 5) necrosis. Stunting is a common symptom for many deficient nutrients due to their varied roles in the plant.
