Effect of irrigation intervals and foliar spray of zinc and silicon

It can be concluded that the scheduling at every 10 days and application of foliar spray of zinc + silicon treatments as the effective one could be recommended for scheduling irrigation at every 10 days with application of foliar spray of zinc + silicon treatments of maize crop at Shandaweel Agricultural Research Station, Sohag Governorate ...

Production of Forage Maize Yield under the Zinc Foliar Fertilization

The objective of presented study was to evaluate the efects of zinc foliar fertilizer and drip irrigation system on some qualitative and quantitative parameters of forage maize. Soil water deficit, drought and unbalanced fertilization are the main reasons maize grain and forage yields decrease.

Effect of irrigation intervals and foliar spray of zinc and silicon

Irrigation water management or scheduling is a decision-making process to determine when and how much water to apply to a growing crop to meet specific management objectives.21 Zinc is most crucial amongst the micronutrients that take part in plant growth and development due to its catalytic action in metabolism of almost all crops.22 a ...

(PDF) Foliar application of Zn: Best way to mitigate

There are many ways to mitigate drought under field conditions but the best and the easiest method is foliar application.

Maize, as one of the world's major food crops, is subject to various factors that influence its yield and quality. Fertilization, a critical measure for enhancing maize productivity and quality, plays a pivotal role. Zinc fertilizer, an essential micronutrient fertilizer, significantly impacts maize growth and development. To determine whether foliar spraying or drip irrigation of zinc fertilizer is more effective, we analyze the pros and cons of both methods from multiple perspectives:

I. Advantages and Disadvantages of Foliar Spraying Zinc Fertilizer

1. Advantages

• Rapid Effectiveness: Foliar spraying directly targets maize leaves and growth points, quickly replenishing zinc and promoting plant growth, particularly under zinc-deficient conditions.
• High Flexibility: The application can be adjusted according to maize growth stages and soil conditions, offering strong adaptability.
• Lower Costs: Compared to drip irrigation and other fertigation methods, foliar spraying has lower operational costs, benefiting farmers financially.

2. Disadvantages

• Environmental Sensitivity: Wind, rain, and other weather conditions may disrupt even distribution of zinc, reducing efficacy.
• Soil Limitation: In saline, alkaline, or poorly drained soils, foliar spraying may yield suboptimal results or exacerbate soil issues.

II. Advantages and Disadvantages of Drip Irrigation Zinc Fertilization

1. Advantages

• Strong Soil Adaptability: Drip irrigation precisely controls water and nutrient delivery, suiting diverse soil types, especially sandy soils, and reducing erosion.
• Water Efficiency: By delivering water directly to roots, evaporation and waste are minimized, optimizing water use.
• Uniform Fertilization: The drip system ensures even distribution of fertilizers, avoiding losses and uneven application common in spraying.

2. Disadvantages

• High Initial and Maintenance Costs: Setting up a drip irrigation system requires significant investment and ongoing upkeep, increasing agricultural burdens.
• Soil Structural Requirements: While water-efficient, improper soil structure may hinder root development and compromise plant health.

III. Comprehensive Comparison and Recommendations

1. Holistic Considerations

Before choosing between foliar spraying and drip irrigation for zinc fertilization, factors such as soil conditions, maize growth stages, and climate must be evaluated. For example, foliar spraying is preferable in zinc-deficient soils or critical growth phases, while drip irrigation suits later growth stages in healthier soils.

2. Localized Adaptation

Regional differences in soil type, climate, and agricultural technology dictate tailored approaches. In arid regions, drip irrigation is ideal, whereas fertile, moderately rain-fed areas may benefit more from foliar spraying.

3. Scientific Management

Regardless of the method, rigorous management is essential. This includes optimizing fertilization timing and dosage to prevent soil salinization, monitoring maize growth, and ensuring adequate nutrient supply.

Both foliar spraying and drip irrigation for zinc fertilization in maize have distinct advantages and limitations. The choice depends on soil conditions, growth stages, climate, and regional context. Prioritizing scientific management and localized strategies is key to maximizing maize yield and quality.
