Zinc is a widely distributed element that occurs in small but adequate amounts in most soils and plants. Zinc functions in enzyme systems, which are important in plant metabolism.
It takes part in the synthesis of chlorophyll in association with Iron and Manganese and hence plays positive role in photosynthesis and Nitrogen metabolism.
It is involved in biosynthesis of plant growth hormone (IAA), and in the reproduction process of certain plants
It is required for seed production, rate of growth and also RNA synthesis.
Intervenial chlorosis of the foliage, particularly in upper leaves, with reduction in the size of young leaves.
Shortening of internodes and stunted growth of plants.
Plants become severely dwarfed.
Flowering, fruiting and maturity can be delayed, shoots may die off and leaves fall prematurely
New leaves of Maize plant that emerge are white in colour, hence the name ‘white bud’
Apply Zinc sulphate @ 10-15 kg / acre before planting.
Spray Zinc in the form of Zinc Sulphate @ 2-3 gm or Zinc-EDTA @ 0.5 gm/ltr two to three times at intervals of 15 days.
Spray micronutreint mixture (powder/ liquid formulations) containing Zinc as recommended
