Solution (By Examveda Team)

White bud-a physiological disorder in sweet corn is caused by the deficiency of Zinc mineral nutrients.
Zinc deficiency is favoured by high soil pH; low organic matter soils with high soil pH; cool, wet soil.
Zinc is relatively immobile in the plant. Severe zinc deficiency may result in new leaves that are nearly white, an effect termed “white bud”.
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.
