1、Zinc wheat Fact Sheet

Soil Tests for Zinc Deficiency status of the soils. Generally, soils containing less than 0.5 ppm DTPA-extractable zinc are classified as poten ially zinc-deficient. Increases in wheat grain yield (more than 20%) as a result of zinc fertilization have been obtained on soils containing less than 0.25 ppm

2、Wheat Fertilizer Requirements

Finally, wheat plants are supplied with S by Zinc sulfate (ZnSO₄), which is usually applied at 25 kg per hectare (22.3 lb per acre) (5). Of course, the farmer should perform soil-plant tissue analysis and adjust the S amounts.

Zinc biofortification of wheat grain

Twenty-six countries have a mandatory minimum wheat grain zinc concentration standard (average 47 ppm); of these 26 countries, the Asian countries’ average standard is 38 ppm (Global Fortification Data Exchange). Montana’s grain could contribute to nourishing its consumers worldwide.

Zinc Application to Wheat – Is it Needed?

We have had a question about whether wheat would benefit from zinc (Zn) fertilizer. Zinc is one of the essential plant nutrients. An optimum amount of Zn is needed for the synthesis of carbohydrates, proteins, and chlorophyll in plants. It also plays a critical role in various enzymatic activities.

The objectives were to evaluate the effect of zinc (Zn) on the yield and yield contributing characters of wheat and to find out the optimum dose and method of Zn application for yield...

Zinc biofortification of wheat through fertilizer and genotype

This study investigated the responses of two wheat varieties, Alvand (Zn-inefficient) and Pishtaz (Zn-efficient), to various zinc (Zn) fertilization methods to determine optimal strategies for enhancing wheat growth and grain quality.

Zinc Wheat

Wheat that is bred to be high in zinc can provide up to 50% of daily zinc needs and contributes to a reduction in zinc deficiency in regions where daily wheat consumption is high.

Wheat, as one of the world's most important food crops, directly impacts national food security and farmers' economic interests. Zinc, an essential microelement for plant growth, plays a critical role in wheat development, yield, and quality. the rational application of zinc fertilizers is vital for improving wheat productivity and quality.

1. Zinc Requirements of Wheat

The demand for zinc in wheat manifests in several key aspects:

(1) Promoting Root Development: Zinc is a component of various enzymes in plants, such as cytokinin oxidase, dehydrogenase, and respiratory enzymes, which are crucial for growth. Proper zinc application enhances root development, strengthens absorption capacity, and improves resistance to drought, cold, and pests.

(2) Enhancing Leaf Growth: Zinc fertilizers stimulate leaf growth, boost photosynthetic efficiency, and increase overall yield.

(3) Facilitating Grain Formation: Zinc promotes grain development, resulting in plump kernels and improved quality.

(4) Improving Disease Resistance: Zinc strengthens disease resistance, reducing the incidence of pathogens and lowering pesticide usage, thereby cutting agricultural costs.

2. Principles of Zinc Application

To ensure adequate zinc uptake in wheat, follow these principles:

(1) Soil-Specific Application: Zinc requirements vary by soil type. Sandy and loamy soils generally need more zinc, while clayey and calcareous soils require less.

(2) Crop-Specific Adjustment: High-yielding or premium wheat varieties demand more zinc compared to standard varieties.

(3) Climate-Based Timing: Adjust applications according to weather. Increase zinc during droughts or heatwaves; reduce it under humid or cool conditions.

3. Methods of Zinc Application

Effective strategies include:

(1) Base Fertilization: Apply zinc evenly before plowing, approximately 1 month prior to sowing, to integrate with the soil.

(2) Topdressing: Supplement zinc during critical growth stages:

• Seedling Stage: Use low-zinc nitrogen and phosphorus fertilizers.
• Jointing Stage: Apply high-zinc nitrogen and phosphorus fertilizers.
• Heading Stage: Provide moderate-zinc nitrogen and phosphorus fertilizers.

4. Precautions for Zinc Application

Key considerations:

(1) Avoid Overapplication: Excessive zinc disrupts nutrient balance and risks toxicity. Stick to optimal rates.

(2) Prevent Alkaline Mixing: Zinc loses efficacy when mixed with alkaline substances. Keep them separate.

(3) Avoid Mixing with Chemical Fertilizers: Combining zinc with synthetic fertilizers may cause reactions that reduce effectiveness or produce toxins.

5. Evaluating Fertilization Effects

Monitor outcomes through:

(1) Plant Observation: Healthy growth, green leaves, and no yellowing indicate adequate zinc. Stunted growth or yellowing suggests deficiencies.

(2) Soil Testing: Measure soil zinc levels. Levels below recommended thresholds signal insufficient application; excess indicates overapplication.

rational zinc application is critical for maximizing wheat yield and quality. Adopt scientific methods, regularly assess outcomes, and adjust strategies to achieve optimal results.
