Fertilizing maize at an optimum nitrogen rate is imperative to maximize productivity and sustainability.

Nitrogen fertilization affects maize grain yield through regulating

High external nitrogen (N) inputs can maximize maize yield but can cause a subsequent reduction in N use efficiency (NUE). Thus, it is necessary to identify the minimum effective N fertilizer input that does not affect maize grain yield (GY) and to ...

Fates and Use Efficiency of Nitrogen Fertilizer in Maize Cropping

Nitrogen (N) fertilization has boosted grain production during the past century, while excess N fertilization with declining N use efficiency (NUE) has led to severe pollution in many regions.

Mechanisms of Nitrogen Use in Maize

Nitrogen is an essential nutrient for maize and a key determinant of grain yield, particularly through its role in photosynthesis and other biological processes such as absorption of water and minerals, vacuole storage, and xylem transport.

Maize Fertilization: Maximizing Yield with Optimal NPK Nutrient

Understanding the delicate balance of nitrogen, phosphorus, and potassium – the pivotal macronutrients in maize fertilization – is crucial for farmers who aim to maximize their yield while minimizing environmental impact.

Late-season fertilizer N applications in maize (Zea mays L.) is a tactical agronomic practice that seeks to improve the synchrony between plant N demand and soil N supply.

Soil, nutrient, and fertiliser requirements for maize (Zea mays

Abstract and Figures Maize (Zea mays) is a key staple crop essential for global food security, with its productivity heavily influenced by soil, nutrient, and fertiliser management.

Maize, as a vital food crop, is widely cultivated globally. In agricultural production, rational fertilization is key to enhancing maize yield and quality. Among the essential nutrients, nitrogen fertilizer plays a critical role in maize growth. This article explores the reasons why nitrogen fertilization is necessary for maize:

1. The Promoting Role of Nitrogen Fertilizer in Maize Growth

• Leaf Development: Nitrogen fertilizer stimulates leaf growth, producing thicker, greener foliage that enhances photosynthetic capacity. Improved photosynthesis increases energy and nutrient supply for the plant.
• Stem Strength: Nitrogen promotes robust stem development, improving structural stability and lodging resistance. Thicker stems enhance wind resistance and pest tolerance.
• Grain Formation: Adequate nitrogen ensures proper grain development, resulting in plump, high-quality kernels. This directly impacts market value and crop quality.

2. Regulation of Maize Growth by Nitrogen

• Growth Rate Control: Nitrogen regulates growth pace, ensuring optimal progression through developmental stages. Timely application prevents excessive or stunted growth.
• Root System Enhancement: Nitrogen fosters extensive root growth, improving water and nutrient uptake. A strong root system boosts stress resilience and overall plant health.
• Disease Resistance: Nitrogen strengthens the plant’s immune response, reducing susceptibility to pests and diseases.

3. Nitrogen and Maize Yield

• Yield Increase: Proper nitrogen use significantly boosts yield by supporting healthy growth and development. Balanced application ensures consistent productivity.
• Higher Per-Hectare Yields: Scientific nitrogen management optimizes utilization, reducing waste and environmental costs while maximizing economic returns.

4. Nitrogen and Maize Quality

• Grain Quality: Nitrogen improves kernel appearance, texture, and nutritional value, enhancing market appeal.
• Starch Content: Nitrogen promotes starch synthesis in grains, increasing their industrial value for processing and consumption.

5. Nitrogen and Stress Resistance

• Cold Tolerance: Nitrogen aids nutrient accumulation, enhancing cold resistance and reducing frost damage.
• Drought Resilience: Nitrogen-driven root expansion improves water absorption, mitigating drought effects in arid regions.

6. Nitrogen and Ecological Balance

• Environmental Protection: Rational nitrogen use minimizes soil salinization and nutrient runoff, preserving ecosystem health.
• Soil Fertility: Proper application maintains soil vitality, promotes microbial activity, and sustains long-term agricultural productivity.

Nitrogen fertilization is essential for maize due to its multifaceted benefits, including enhanced growth, yield, quality, and stress resistance. excessive application risks environmental harm. Scientific management of nitrogen timing and dosage is crucial to balancing productivity, profitability, and sustainability.
