The crop only requires around 0.05 kg Zn/ha (both straw and grain) per ton of grain yield, but much more Zn fertilizer must be applied because Zn once applied is not very available to the plant.

Essential for the transformation of carbohydrates.
Regulates consumption of sugars.
The function of zinc in plants is as a metal activator of enzymes.
Deficiency of zinc in lowland rice occurs in near neural to alkaline soils, particularly in calcareous soils.
Availability of both soil and applied zinc is higher in upland soil than in submerged soil.
Soil submergence causes decrease in zinc concentration in the soil solution.
Rice crop removes 30-40 g Zn per tonne of grain.
Zinc Deficiency: The symptoms of zinc deficiency appear 2-3 weeks after transplanting (Plate No. 1, page 186). The lower leaves become rusty brown near the base and ultimately dry up. The seedlings with zinc deficiency remain stunted and tillerless. To control this malady, apply 25 kg of zinc sulphate heptahydrate (21%) or 16 kg zinc sulphate monohydrate (33%) per acre at puddling in case previous crop in this field had shown the symptoms of zinc deficiency. Where the deficiency is noticed in the growing crop, apply this quantity of zinc sulphate as soon as possible.
In highly deteriorated soils, the symptoms of zinc deficiency sometimes appear in patches even after the application of the recommended dose of zinc sulphate. In that event, broadcast 10 kg of zinc sulphate heptahydrate or 6.5 kg zinc sulphate monohydrate per acre mixed with an equal quantity of dry soil on the affected patches
