What is the role of Zinc (Zn) in plants
Zinc is an essential plant nutrient required for several biochemical processes in the rice plant, including chlorophyll production and membrane integrity. Thus, Zn deficiencies affect plant color and turgor. Zn is only slightly mobile in the plant and quite immobile in soil.
Why apply Zinc to Rice
Zinc limits plant growth when the soil supply of Zn is low or adverse soil
In such cases, Zn needs to be applied as required. Other nutrients need to be applied in balanced amounts to ensure a good crop response to fertilizer Zn application and to achieve a healthy and productive crop.
How to manage Zn
What are the sources of Zn
The commonly used Zn fertilizers are soluble zinc sulfate (23−36% Zn), soluble zinc chloride (48−50% Zn), and insoluble zinc oxide (60−80% Zn).
