Zinc Deficiency in Wheat: Identifying and Fixing It Before Boot Stage
Zinc-deficient wheat shows chlorotic streaking between the leaf veins, particularly on younger leaves, along with stunted growth and reduced tillering — symptoms that are often mistaken for nitrogen shortage or general poor establishment early in the season.
Because zinc demand in wheat is highest during tillering and stem elongation, correcting a deficiency after the crop reaches boot stage does little to recover the tillers and yield potential already lost — timing the correction to early growth stages matters more than the total quantity applied.
A basal soil application of zinc sulphate at or before sowing — Agro Gold (21% Zn), Saffaron (27% Zn), or Commander (33% Zn) — remains the most reliable way to prevent deficiency from limiting tillering in the first place, especially on the alkaline, calcareous soils common across Pakistan's wheat belt.
Where a field has a documented history of zinc problems, pairing a soil application with a single foliar spray during early tillering gives the crop two chances to take up zinc before the demand window closes, rather than relying on one application alone.
