orial experiment, laid out in a randomized complete block design (RCBD) with three replications. Factor 1 was maize cob foliar fertiliser type (soaked cob leachate (SCL): 1.4 % K and cob ash leachate (CAL): 0.16 % K. Factor 2 was frequency of application of the cob leachates during the growth cycle of the maize crop; viz (1) Control, (2) once at

3、Foliar nickel fertilization enhances photosynthesis and defines

The aim of this study was to evaluate the effect of foliar application of Ni doses on gas exchange, nutrition, biochemistry, physiology and grain yield of maize plants.

Fertilization regulates maize nutrient use efficiency through soil

Its high biomass production necessitates substantial fertilizer inputs; however, inadequate nutrient availability adversely affects maize yield and hampers its growth and development. The southwest mountain maize production region is recognized as one of the advantageous areas for maize cultivation in China.

Maize Fertilization: Maximizing Yield with Optimal NPK Nutrient

In the quest for agricultural excellence, the role of nutrition in maize cultivation cannot be overstated. A well-fertilized maize crop is the cornerstone of not just a bountiful harvest, but also of the sustainability and efficiency of modern farming practices.

Nitrogen fertilization coupled with iron foliar application improves

For instance, intercropping increased the maize’s chlorophyll SPAD values by 8% without fertilization, 11% with nitrogen fertilization, and 13% with nitrogen fertilization coupled with foliar application of iron (Figure 3A).

The Effect of Foliar Micronutrient Fertilization on Yield and

Mineral fertilizers are most commonly applied either to the soil or as foliar sprays, with the former method predominantly used for macronutrient fertilization. In contrast, foliar application complements soil fertilization and is often the only feasible method for supplying micronutrients.

The Effect of Foliar Micronutrient Fertilization on Yield and

The study highlights the potential of foliar fertilization to improve maize performance and grain quality, despite possible antagonisms between micronutrients.

Suitable fertilization can improve maize growth and nutrient

Nitrogen fertilization coupled with iron foliar application improves the photosynthetic characteristics, photosynthetic nitrogen use efficiency, and the related enzymes of maize crops under different planting patterns.

Maize, as one of the world's most important grain crops, requires precise foliar fertilization strategies during its growth cycle to ensure yield and quality. Below is a detailed explanation of the number of foliar fertilization applications needed for maize, along with recommendations for rational fertilization at different growth stages:

I. Growth Stages of Maize and Corresponding Foliar Fertilization Needs

1. Germination Stage (Seed Emergence to Seedling Breakthrough)

During germination, root development and the emergence of the first true leaf are prioritized. As roots are not fully formed, nutrient demands are low. Foliar fertilization is generally unnecessary at this stage.

2. Seedling Stage (First True Leaf to Jointing)

As seedlings transition to the ear differentiation stage, growth accelerates, increasing nutrient demands. Applying moderate nitrogen via foliar spray promotes rapid stem elongation and leaf expansion, laying a foundation for later development.

3. Jointing to Tasseling Stage (Post-Jointing to Pre-Tasseling)

During this rapid growth phase, stems elongate, and leaves multiply. Continuous nitrogen application via foliar spray supports vigorous growth, while supplemental phosphorus, potassium, and micronutrients enhance plant health.

4. Tasseling to Grain Filling Stage (Post-Tasseling to Maturity)

Nutrient demands peak during grain filling, particularly for nitrogen, phosphorus, and potassium. Heavy foliar applications ensure sufficient major nutrients, while micronutrients like calcium and magnesium prevent deficiencies.

II. Foliar Fertilization Methods and Precautions

1. Select Appropriate Fertilizers

• Germination stage: High-nitrogen formulas to boost early growth.
• Ear differentiation to tasseling: Balanced N-P-K blends.
• Grain filling: Emphasize N-P-K with micronutrient supplements.

2. Application Best Practices

• Follow the "small doses, frequent applications" principle to avoid over-fertilization.
• Apply on calm, sunny days to ensure optimal absorption.

3. Safety and Environmental Considerations

• Wear protective gear to avoid skin/respiratory contact.
• Choose eco-friendly fertilizers and prevent runoff to minimize environmental impact.

III. Comprehensive Management and Continuous Improvement

1. Soil Management

• Conduct soil tests before fertilization to assess nutrient levels and pH.
• Improve soil health with organic amendments and balanced fertilization.

2. Water Management

• Maintain soil moisture to prevent fertilizer loss or waterlogging.
• Irrigate based on weather and soil humidity to support growth.

3. Pest and Disease Control

• Use crop rotation, resistant varieties, and sanitation to reduce pest/disease risks.
• Apply bio-or chemical controls promptly if issues arise.

Maize typically requires three key foliar applications: during the seedling stage, jointing-tasseling stage, and grain filling stage. Adjust strategies based on growth stages and soil conditions. Integrate soil, water, and pest management practices to achieve high yields and efficiency.
