1、Effect of foliar application of bio

Foliar application of amino total (1.2 ml l-1) or yeast (2 g l-1), as bio-stimulants can be recommended to enhance total yield and bulb quality of garlic, while foliar application of ascorbic acid was the best for bulbs storability.

2、The Effect of Slow

The effects of these treatments on garlic seedling yield, growth quality, chlorophyll content, photosynthetic characteristics, and the soil environment were investigated to evaluate the feasibility of replacing conventional fertilizers with slow-release formulations.

3、The Effect of Foliar Fertilization on the Yield and Quality of Different Crops

To avoid these complications, preventive foliar fertilization can be useful, specially for varieties with a high potential of yield and quality, and in climatically suboptimal years.

4、FOLIAR NUTRITION IN CROPS

Fertilizer is a vital input in agriculture to boost the crop yields. Among the methods of fertilizer application, foliar nutrition is recognized as an important method since it facilitates easy and rapid utilization of nutrients.

Growth and Nutrients Content and Uptake of Garlic (<i>Allium sativum L.</i>) as Influenced by Different Types of Fertilizers and Soils

Thus, the study was conducted on Andosol and Vertisol soils at Debre Zeit Agricultural Research Center, Ethiopia, for two consecutive (dry and main rainy) seasons to assess the effect of various rates of compound fertilizers on growth, and nutrient content and uptake of garlic.

Garlic in the Garden

Fertilization: In addition to the fertilizer used at planting, garlic needs additional nitrogen fertilizer to produce optimum yields. Side-dress with 1⁄2 pounds of nitrogen fertilizer (21-0-0) per 100 square feet in mid-April and 1⁄4 pounds in late May.

The best results were obtained by using 96 kg K2O/fed with foliar application of pix at 500 ppm. Therefore, this treatment could be recommended for raising garlic yield and improving bulb quality during the storage period under similar conditions to this work.

Aqueous garlic extract stimulates growth and antioxidant enzymes activity of tomato

A glasshouse bioassay was conducted to assess the efficacy of aqueous garlic extract (AGE) as a biostimulator for the growth improvement of tomato seedlings. Application of AGE as foliar spray and/or fertigation, resulted in morphological and physiological stimulation of tomato seedlings.

Soil applications of fertilizers are mainly done on the basis of soil tests, whereas foliar nutrient applications are mainly done on the basis of visual foliar symptoms or plant tissue tests. Hence, correct diagnosis of nutrient deficiency is fundamental for successful foliar fertilization.

THE EFFECT OF FOLIAR APPLICATION OF UREA AND AMINO ACIDS ON THE GROWTH AND YIELD AND CHARA

It could be concluded that, foliar application of urea resulted in the highest fruit yield and the best physical and chemical quality, followed by plants supplied by amino vit plus.

Garlic is an important vegetable crop with high nutritional demands during its growth. Foliar fertilization, a modern approach to nutrient application, involves spraying nutrients directly onto plant leaves for rapid absorption and transport, enhancing growth speed and yield. Selecting the appropriate foliar fertilizer is particularly critical for garlic. Below are some recommendations for optimizing foliar fertilizer use in garlic cultivation:

1. Choose Suitable Foliar Fertilizer Formulations

Garlic requires significant amounts of nitrogen (N), phosphorus (P), and potassium (K). Prioritize fertilizers rich in these macronutrients. Additionally, tailor the formula to the growth stage and local climate. For example:

• Vegetative growth stage: Emphasize nitrogen to promote leaf development and photosynthesis.
• Bud differentiation stage: Increase phosphorus and potassium to support bud formation and development.

2. Opt for High-Concentration, Readily Absorbable Formulations

Due to garlic’s shallow root system, soil-based fertilization may be inefficient. Choose:

• High-concentration fertilizers: Provide adequate nutrients quickly.
• Water-soluble and stable formulations: Prevent precipitation or clumping during spraying, ensuring even coverage.

3. Time and Method of Application

• Timing: Adjust nutrient ratios based on growth stages (e.g., more nitrogen early, phosphorus/potassium later).
• Application:
  • Dilute fertilizer and spray uniformly on leaves, avoiding direct root contact.
  • Apply every 7–10 days for consistent results.

4. Adjust Dosage Based on Soil Conditions

Soil quality impacts fertilizer effectiveness:

• In poor or saline soils, increase foliar fertilizer dosage to compensate for reduced nutrient uptake.
• Avoid overapplication to prevent nutrient excess, which may harm plants.

5. Integrate with Other Fertilization Methods

Combine foliar fertilizers with other approaches for optimal results:

• Mix with organic fertilizers to improve soil structure and fertility.
• Pair with water-soluble fertilizers to boost nutrient availability and efficiency.

Maximizing garlic yields requires:

• Selecting appropriate foliar fertilizers (rich in N, P, K).
• Using high-concentration, stable formulations.
• Timing applications to growth stages and soil needs.
• Integrating foliar fertilization with other methods.

By adapting these strategies to specific conditions, growers can significantly enhance garlic growth and productivity.
