Optimal Stages for Foliar Fertilization in Maize Crops

Foliar fertilization with biostimulants obtained from chicken feathers (rich in organic matter, low molecular weight peptides and amino acids) significantly increased the maize nutrition and, consequently, maize yield and grain quality.

Which Foliar Fertilizers Are Effective for Late

In agricultural production, foliar fertilization is a critical practice to enhance maize yield and quality. Foliar fertilizers, applied by spraying nutrients directly onto plant leaves, play a vital role during the late growth stages of maize.

Frontiers

In this study, we conducted a 48-day pot experiment to explore how blending low-P fertilizers could optimize maize P utilization, using CMP to replace DAP in acidic soil, and SSP to replace MAP in alkaline soil, with five SSP+MAP and CMP+DAP mixtures tested.

Maize is one of the world's most critical food crops, and its yield directly impacts national food security and farmers' income. Rational fertilization is essential for improving maize productivity. Foliar fertilizers, as a highly efficient nutrient delivery method, enable direct absorption through leaves, promoting plant growth and development. They offer advantages such as ease of use and rapid effects. Below are recommendations for optimizing foliar fertilizer formulations to enhance maize growth:

I. Understanding Maize Growth Requirements

1. Nutrient Needs: Maize requires large amounts of nitrogen (N), phosphorus (P), and potassium (K) during growth. Nitrogen promotes leaf expansion and photosynthesis, phosphorus supports root development and seed formation, while potassium enhances disease resistance and drought tolerance.

2. Water Requirements: Maize has high water demands, especially during the seedling and jointing stages. Water scarcity can lead to stunted growth, yellowed leaves, and delayed development.

3. Light Requirements: Maize thrives under ample sunlight, which drives photosynthesis and boosts yields. excessive exposure can cause leaf scorching. Balancing light intensity and duration is key to healthy growth.

II. Selecting Appropriate Foliar Fertilizers

1. Fertilizer Types: Common foliar options include:

   • Potassium dihydrogen phosphate (KH₂PO₄): A balanced compound fertilizer.
   • Urea: Primarily for nitrogen supplementation.
   • Borax (B) and ammonium molybdate (Mo): Enhance disease resistance and root development, respectively.

2. Concentration Control: Fertilizer concentrations must be carefully calibrated to avoid foliar burn or toxicity. Follow product guidelines or consult agronomists to determine optimal dilution ratios.

3. Timing of Application: Apply foliar sprays in early morning or late afternoon when plants’ absorption rates peak. Avoid midday heat to prevent leaf damage.

III. Scientific Formulation of Foliar Mixtures

1. N-P-K Ratios: A typical ratio is 10% nitrogen, 5% phosphorus, and 40% potassium, tailored to maize’s nutritional needs while minimizing over-fertilization risks.

2. Micronutrient Addition: Adjust formulations based on soil tests:

   • Zinc deficiency: Add zinc sulfate.
   • Iron deficiency: Use ferrous sulfate.
   • Manganese deficiency: Include manganese sulfate.

3. Combining with Other Fertilizers: Integrate foliar sprays with compound fertilizers to improve nutrient uptake efficiency. monitor compatibility between mixed products to avoid chemical reactions.

IV. Key Considerations

1. Avoid Over-Fertilization: Excessive use harms plants, disrupts soil health, and pollutes the environment. Adhere to "appropriate dosage" principles.

2. Application Techniques:

   • Spray on sunny, calm days.
   • Ensure even coverage of all leaves.
   • Rinse foliage with water post-spray to prevent residue buildup.

3. Monitor Effects: Regularly observe plant responses. If abnormal growth or yield drops occur, reassess application methods or adjust strategies. Continuous refinement maximizes fertilizer benefits.

Optimizing foliar fertilizer formulations is vital for maize productivity. By aligning nutrient ratios, timing, and application techniques with maize’s physiological needs, farmers can significantly boost yields. foliar fertilization should complement broader agronomic practices, such as proper planting density and irrigation management, to achieve stable, high-quality production.
