The maize filling stage is a critical period in maize growth, during which kernels begin to form, and the demand for boron fertilizer increases accordingly. Applying boron fertilizer during this stage can effectively promote maize growth and enhance yield. Below is a detailed explanation of boron fertilizer application during the maize filling stage:

1. Mechanism of Boron Fertilizer

Boron is an essential plant nutrient element that plays a vital role in growth and development. It promotes cell division and elongation, enhances stress resistance and disease resistance, and boosts photosynthesis and respiration, thereby improving metabolic efficiency.

2. Physiological Characteristics of the Maize Filling Stage

The filling stage refers to the process of kernel formation and enlargement. During this period, maize requires more boron to support kernel development. Additionally, this stage is critical for water and nutrient absorption, making boron supply indispensable for normal growth.

3. Effects of Boron Application

Applying boron fertilizer improves yield and grain quality. Studies show that boron increases ear height, leaf area per plant, stalk strength, and lodging resistance. It also enhances kernel size, weight, color, and taste.

4. Methods of Boron Application

• Foliar Spraying: Dilute boron fertilizer and spray it onto maize leaves. Simple to use but requires careful dosage to avoid boron toxicity.
• Soil Application: Dissolve boron in water and evenly spray it around the root zone. Provides prolonged nutrient release but depends on adequate soil moisture.
• Root Zone Application: Directly spray boron onto the soil near roots. Improves absorption efficiency but is more labor-intensive.

5. Optimal Timing for Application

The best time to apply boron is during the filling stage and its前后 (before and after). Application can begin at the jointing stage and continue until maturity, aligning with peak boron demand.

6. Precautions

• Dosage: Adjust based on conditions (e.g., 50-100 kg/mu). Excessive application causes boron toxicity.
• Weather: Avoid rainy, windy, or high-temperature periods to prevent reduced effectiveness.
• Soil Conditions: Check pH and nutrient levels before application. Combine with other fertilizers if soil quality is poor.

7. Economic Analysis

Boron application is cost-effective and yields high economic returns. By improving yield and grain quality, it increases market value, making it a valuable agricultural practice worth promoting.

Applying boron during the maize filling stage boosts growth and yield. success depends on proper dosage, timing, and soil conditions. Coupled with rational fertilization and pest management, this practice supports comprehensive yield increases.
