1、The difference and preparation between plant growth regulators and

Plant growth regulators and foliar fertilizers are widely used in agricultural planting. Plant growth regulators can control, promote or regulate the growth and development of plants, while foliar fertilizers provide plants with the required nutrients through foliar spraying.

2、Effects of different fertilization practices on maize yield, soil

Our results provide a theoretical basis for fertilizer application and for improving the soil structure for maize cultivation in northern China.

3、Fertilization regulates maize nutrient use efficiency through soil

This study investigated the effects of different fertilization methods on rhizosphere biological network, transcriptome responses in maize roots, fertilizer use efficiency and maize yield in a long-term field experiment.

4、(PDF) Response of maize to foliar vs. soil application of nitrogen

All indices increased in response to all forms of foliar fertilization (FF), but no significant difference was obtained between the different forms.

5、Effects of Foliar Fertilization: a Review of Current Status and Future

Compared with root fertilization, foliar fertilization, as a supplementary fertilization strategy, can deliver nutrients directly to the target through aerial plant parts, thereby helping to reduce negative impacts on the soil (Bindraban et al. 2015; Fernández and Eichert 2009).

EFFECTS OF DIFFERENT FOLIAR TREATMENTS AT MAIZE CROP

foliar fertilization increased (Jakab et al., 2016). Nutrient uptake through leaf stomata is faster compared to root absorption, making it an efficient approach to promptly rect.

Effect of Nutrient Forms in Foliar Fertilizers on the Growth and

This research aimed to evaluate how different chemical forms of key nutrients, delivered through an advanced foliar product (PRO) and a standard formulation (TRA), influence maize performance when grown on contrasting soil types.

Reducing Pollution due to Maize Nitrogen Fertilization by using Foliar

Thereby, among factors that enhance maize productivity via foliar fertilization with growth regulators such as gibberellic acid (GA 3) and natural growth promoters i.e., amino acids and yeast extract as a modern trends in fertilizing maize as well as mineral nitrogen fertilization.

Effect of foliar application of nutrients and plant growth regulator

Hence, foliar application of nutrients and plant growth regulators may be more effective in increasing maize productivity than other crop management options. The objective was to quantify the impacts of foliar application of nutrio-hormonal consortia on the physiological and yield traits of maize.

RESPONSE OF MAIZE TO FOLIAR VS. SOIL APPLICATION OF NITROGEN–PHOSPHORUS

The aim of the present study was to determine the efficiency of different forms of nitrogen–phosphorus–potassium (NPK) fertilizers applied to maize (Zea mays L.), either to the soil or to the leaves.

Foliar fertilizers and regulators for maize both play important roles in agricultural production, but they differ in mechanisms, composition, and application methods.

1. Mechanisms of Action

• Foliar Fertilizer: Primarily enhances nutrient absorption and utilization efficiency by applying nutrients directly to maize leaves. It typically contains essential nutrients such as nitrogen (N), phosphorus (P), potassium (K), zinc (Zn), iron (Fe), etc., which meet the crop’s demands at different growth stages. The mechanism involves delivering nutrients directly into the plant to promote growth and development.

• Regulators: Chemicals designed to modulate plant physiological activities, including growth rate, photosynthesis, respiration, and other processes. Their effects vary by type: some improve photosynthetic efficiency (e.g., photosynthetic hormones), while others inhibit growth (e.g., growth retardants). Proper selection and dosage are critical, as specified in usage guidelines.

2. Composition

• Foliar Fertilizer: Contains macronutrients like N, P, K, Zn, Fe, and microelements such as boron (B), molybdenum (Mo), copper (Cu), which influence maize growth and yield.

• Regulators: Composition varies by function. Examples include organic acids, amino acids, nucleotides, vitamins, or specialized hormones. Specific formulations target processes like photosynthesis enhancement or growth suppression.

3. Application Methods

• Foliar Fertilizer: Applied via spraying onto maize leaves after cleaning them to ensure even coverage. Avoid overapplication to prevent leaf burn.

• Regulators: Require precise selection based on crop needs and strict adherence to dosage instructions. Concentrations are typically low, and improper use may harm plants.

4. Advantages and Disadvantages

• Foliar Fertilizer:

  • Advantages: Rapid nutrient supplementation, improved growth, and yield potential.
  • Disadvantages: Risk of leaf burn if misused.

• Regulators:

  • Advantages: Optimize physiological processes (e.g., enhanced photosynthesis or controlled growth).
  • Disadvantages: Require meticulous dosage control to avoid adverse effects.

Both foliar fertilizers and regulators are vital tools in agriculture, but they serve distinct purposes. To ensure healthy crop growth and maximize yields, farmers should choose products based on specific requirements and follow application guidelines rigorously.
