1、Foliar magnesium application improves sweet corn yield: boosting

The results showed that foliar spraying with 4% Mg significantly increased sweet corn fresh ear yield, ear weight, grain fresh weight, and grains per ear, while reducing the abortion rate compared to the foliar water spraying (CK) treatment across all three seasons.

2、Foliar nutrition: Potential and challenges under multifaceted

The potential of foliar fertilization in improving crop yield and quality under environmental stresses has been evaluated based on a meta-analysis. Foliar-applied fertilizers showed higher crop plants yield and quality traits by 15–19% and 9–29%, respectively, under different environmental stresses.

3、2026 Field Research Report Foliar fertilizers in Corn 2026

Foliar applied nutrients have been used to supplement soil applied nutrients in corn. Nitrogen, phosphorus, potassium, iron, and sulfur are nutrients that can potentially improve corn yield when applied as a foliar treatment.

4、Effective Foliar Fertilizers for Corn: Selection and Application Techniques

Traditional phosphorus fertilizers are necessary for plant growth but about 80–90% are lost into the surrounding environment via irrigation, therefore nano-fertilizers have been developed as slow-release fertilizers to achieve sustainable agriculture.

5、‌Core formula of corn foliar fertilizer spraying

‌The core formula of corn foliar fertilizer spraying is a combination of potassium dihydrogen phosphate, zinc-boron micro-fertilizer and brassinolide. Adjusting the ratio in combination with different growth stages can significantly improve yield and stress resistance.

Influence of Foliar Fertilization on Yield and Grain Quality of Corn

We examined the influence of foliar fertilization on the yield and grain quality of corn in 2018. The experiment was set in three replications, random blocks on the area of Tangazdaság Ltd....

ASSESSMENT OF THE IMPACT OF COMPLEX FOLIAR FERTILIZERS ON CORN (ZEA

This study investigates the effects of foliar fertilization (FF) on the yield and quality of corn grains, utilizing Principal Component Analysis (PCA) to optimize foliar treatment applications.

Effect of foliar spraying with nano composite fertilizers and organic

nano fertilizer was 40 days after germination, and the second was 14 days after the first spray, while the first is for the organic fertilizer after 47 days of germination and the second is after 14 days of the first spraying, depend on on the information on the envelopes containing the fertilizers.

Foliar feeding of corn / maize – the way to achieve better crops

After male inflorescence the plant nutrient uptake from leaf and soil is reduced to minimum, and the plant consists on the former feeding given from 7-9 leaves (50 cm) to 14 leaves (1.5 m), therefore it is important to supply N and K in this critical stage.

In this blog, we’ll layout the three most critical stages where a foliar application can dramatically improve performance—and introduce a premium foliar-applied program designed to enhance photosynthesis, increase plant vigor and boost yields under stress.

After corn pollination, applying foliar fertilizers is a critical measure to enhance yield and improve quality. Selecting the appropriate foliar fertilizer is essential for promoting healthy corn growth and increasing productivity. Below is a detailed introduction to suitable foliar fertilizers and their application methods for use after corn pollination:

I. Principles of Foliar Fertilization

1. Clear Objectives: Define the purpose of fertilization, whether to boost growth or enhance corn quality. For example, if increasing sugar content is the goal, choose a fertilizer rich in sugars.
2. Fertilizer Selection: Tailor the fertilizer to the corn’s growth stage and soil conditions. Use growth-promoting formulas during early stages and disease-resistance formulas as corn matures.
3. Concentration Control: Avoid overly concentrated solutions to prevent damage. Dilute to recommended strengths before application.
4. Timing: Apply during critical growth phases (e.g., tasseling or grain-filling stages) for optimal results.
5. Correct Methods: Ensure even coverage using spraying, drip irrigation, or other techniques to maximize effectiveness.
6. Environmental Suitability: Choose calm, low-wind conditions to prevent drift and ensure proper absorption.
7. Safety First: Use human-and-crop-safe formulations, avoiding toxic ingredients.

II. Types of Foliar Fertilizers

1. Microelement Fertilizers: Such as boron, zinc, or iron-based products, which enhance photosynthesis and stress resistance.
2. Amino Acid-Based Fertilizers: Examples include aspartic acid complexes or glutamine blends, which stimulate root development and nutrient uptake.
3. Hormone-Based Fertilizers: Gibberellin, cytokinins, and similar regulators that optimize growth cycles.
4. Bio-Bacterial Fertilizers: Containing rhizobia or nitrogen-fixing bacteria to improve soil structure and organic matter.
5. Seaweed-Based Fertilizers: Rich in minerals and trace elements (e.g., algal polysaccharides) to address nutritional deficiencies.

III. Application Methods

1. Spraying: Dilute and directly apply to leaves. Ensure uniform coverage to avoid overdosing.
2. Drip Irrigation: Mix with water and deliver near roots via drip systems for efficient use.
3. Soaking: Submerge corn stalks in solution to boost leaf absorption and nutrient transport.
4. Combined Soaking and Spraying: Pre-soak stalks before spraying to protect leaves and enhance uptake.
5. Topical Application: Directly apply fertilizer to leaves, ideal for broad-leaf corn varieties.

IV. Evaluating Effects

1. Growth Metrics: Monitor growth rate, plant height, and leaf count.
2. Yield Metrics: Measure total yield, ear count, and kernel weight per cob.
3. Quality Metrics: Assess sugar, protein, and fat content to gauge improvements.
4. Disease Resistance: Test changes in pest/disease susceptibility through field observations or inoculation trials.
5. Stress Tolerance: Evaluate performance under drought, heat, or cold stress to confirm resilience gains.

select fertilizers based on corn’s growth stage and soil conditions, and apply using proper techniques. By assessing outcomes, refine strategies to maximize yield and quality post-pollination.
