This study investigated the effects of four selenium fertilizers (nano-Se, EDTA-chelated Se, organic Se, and microbial Se) at three concentrations (50, 25, and 12.5 mg·L−1) on garlic (Allium sativum L. cv. ‘Xusuan 918’) through foliar application during critical growth stages.

2、What is the ideal foliar fertilizer for promoting garlic bulb growth?

To ensure maximum health and growth of your garlic bulbs, a balanced fertilizer like NPK should be lightly applied prior to planting. Additionally, enrich the soil with organic compost or manure for improved root strength and development.

Garlic Fertilizer Guide

Whatever types of garlic you are growing, the best fertilizer is one that provides plenty of nitrogen. This essential nutrient drives leafy green growth in spring, which later fuels bulb development. If you’re growing organically, then opt for a natural product like blood meal, alfalfa meal, or fish emulsion.

Foliar spraying of aqueous garlic bulb extract stimulates growth and

Foliar application of aqueous garlic bulb extract (AGE) accelerates plant growth through the stimulation of photosynthetic pigments and soluble sugar content (Hammad 2008; Hanafy et al. 2012).

How to Fertilize Garlic for Best Yield

Mix compost or old manure into the soil. Opt for slow-release fertilizer with 10-10-10 N:P:K ratio. Add a tablespoon of fertilizer per garlic clove or three tablespoons per bulb. Plant cloves two inches deep and six inches apart. Water deeply after planting to stimulate root growth.

Effects of different foliar fertilizers and biological regulators on

Abstract: During the period from garlic turning green to flower bud differentiation, the effects of different types of foliar fertilizers and biological regulators on the growth of aboveground plants and underground bulbs of different types of garlic were studied using the method of foliar spraying.

Garlic bulb enlargement is a critical phase in garlic cultivation, involving the plant's absorption and utilization of nutrients. Foliar fertilizers, applied directly to plant leaves, rapidly replenish essential nutrients, promote growth, and boost yields. Selecting the right foliar fertilizer during garlic’s enlargement stage can significantly enhance bulb development. Below are guidelines for choosing and applying foliar fertilizers effectively:

I. Selection of Foliar Fertilizers

1. Nitrogen-Based Fertilizers Nitrogen is vital for stem and leaf growth and flower bud differentiation. During bulb enlargement, nitrogen-rich foliar fertilizers increase leaf quantity, ensuring adequate photosynthesis to support bulb growth.

2. Phosphorus-Based Fertilizers Phosphorus promotes root development, cell division, and disease resistance. Applying phosphorus-rich foliar fertilizers during this stage enhances root growth and improves water/nutrient uptake.

3. Potassium-Based Fertilizers Potassium regulates cellular osmotic pressure and stress resistance. Potassium-rich foliar fertilizers strengthen roots, improve pest/disease resistance, maintain soil moisture, and aid bulb expansion.

4. Micronutrient Fertilizers Trace elements like iron, zinc, and copper are crucial for garlic growth. Micronutrient foliar fertilizers support photosynthesis and overall health.

5. Compound Foliar Fertilizers Market-available compound fertilizers combine multiple nutrients tailored to garlic’s needs, providing comprehensive nutrition and optimizing fertilization outcomes.

II. Application Techniques

1. Dilution Ratio Follow product instructions for dilution. Avoid over-concentration (risk of leaf burn) or under-concentration (reduced efficacy).

2. Timing Apply in early morning or evening when temperatures are cool, leaves are turgid, and absorption is maximized. Avoid heat-stressed periods.

3. Spraying Method Ensure even coverage of leaves without oversaturation. Focus on thorough application to all leaf surfaces.

4. Frequency Typically, one to two applications during bulb enlargement are sufficient. Adjust based on growth conditions and soil health.

5. Monitor Response Observe garlic for yellowing, stunted growth, or other stress signs. Discontinue use if issues arise and revise the fertilization plan.

III. Key Considerations

1. Avoid Overapplication Excessive use may lead to excessive vegetative growth or root damage. Adhere to recommended dosages.

2. Prevent Alkaline Mixing Avoid combining foliar fertilizers with alkaline substances, which may reduce efficacy or create toxicity.

3. Soil Compatibility Match fertilizers to soil pH and type (e.g., sandy vs. clay soils) for optimal results.

4. Balanced Fertilization Integrate foliar fertilizers with other nutrients (e.g., pair nitrogen with phosphorus/potassium). Account for nutrient interactions.

5. Growth Monitoring Regularly assess garlic health. Address abnormalities (e.g., irregular growth, diseases) by adjusting fertilization strategies.

selecting appropriate foliar fertilizers and mastering application techniques are key to maximizing garlic bulb size and quality. Proper fertilization management enhances agricultural productivity and farmer income.
