1、Roles of Foliar Fertilization on Growth, Yield and Quality of Tomato

Foliar fertilization to be effective and maximize crop yield and nutrient uptake, the "right type," "right rate," "right time “and” right place" are essential. The right nutrient selection...

2、Localized foliar application of iodine on tomato: An effective approach

Foliar application localized on the leaves close to the fruit maximizes its iodine concentration. Rates of KIO solution less than or equal to 5 mM do not affect yield and plant health. Iodine application can improve the nutritional profile of tomatoes.

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

Chelated foliar fertilizers are effective for improving element utilization efficiency, crop yield, and quality. The physicochemical properties, molecular structure, chelating strength, and chelating rate of chelating agents modulate the effects of application of nutrients.

Yield and Fruit Characteristics of Tomato Crops Grown with Mineral

In conclusion, the biostimulants based on humic acid and amino acids combined with chemical fertilizers tested in the present study and applied by fertigation were more effective in improving tomato yield, and therefore they can be recommended for efficient agricultural production.

Chelated foliar fertilizers are effective for improving element utilization efficiency, crop yield, and quality. The physicochemical properties, molecular structure, chelating strength, and chelating rate of chelating agents modulate the effects of application of nutrients.

Tomato Leaf Curling Causes and Effective Remedies

Foliar Feeding: Give your plants a quick nutrient boost by misting their leaves with a diluted organic fertilizer or seaweed extract. This is especially helpful in hot, dry weather when soil absorption can be limited.

Cure Tomato Leaf Curling: Causes, Effects & Solutions Found!

In this comprehensive guide, we’ll help you diagnose and prevent curled leaves on your tomatoes, so you can get back to enjoying a bountiful harvest. We’ll cover common causes of leaf curl, as well as practical solutions to get your plants back on track, from prevention techniques to emergency fixes.

Tomato leaf curling can result from various causes, including nutrient deficiencies, improper water management, pest/disease issues, or environmental factors. Foliar fertilization is an effective method to supplement nutrients and improve crop growth. Below are recommended foliar fertilizers, application methods, and guidelines for selecting and using them based on specific needs:

I. Selection of Foliar Fertilizers

1. Potassium Dihydrogen Phosphate (KH₂PO₄) This widely-used fertilizer provides essential phosphorus and potassium, promoting root development and fruit maturation. Dissolve 0.2%–0.5% solution and spray evenly on both leaf surfaces, avoiding direct contact to prevent burning.

2. Boron Fertilizer Boron enhances tomato disease resistance. Dilute boron fertilizer to 0.1%–0.3% concentration before foliar application.

3. Amino Acid Complex Solution Rich in amino acids and microelements, this fertilizer boosts plant growth and fruit quality. Follow product instructions for dilution and ensure uniform leaf coverage.

4. Seaweed Extract Contains minerals and microelements that strengthen tomato immunity and stress resistance. Mix with water at the recommended ratio and spray thoroughly.

II. Timing of Foliar Application

• Flowering Stage: Use boron, nitrogen, or phosphorus-based fertilizers to promote flower bud differentiation and improve fruit setting.
• Fruiting Stage: Apply high-potassium fertilizers during fruit enlargement to enhance yield and quality.
• Early Growth Stage: Nitrogen, phosphorus, and potassium-balanced fertilizers support rapid seedling growth.
• Late Growth Stage: High-phosphorus formulas improve disease resistance and lodging tolerance.

III. Application Methods

1. Clean Leaves: Remove dust or debris from leaves before application to ensure absorption.
2. Dilute Properly: Follow dosage instructions (typically 1:100–1:200 ratio) to prepare the solution.
3. Spray Uniformly: Cover both leaf surfaces thoroughly to avoid nutrient imbalance.
4. Monitor Response: Observe plants post-application; adjust dosage or discontinue if abnormalities occur.

IV. Precautions

1. Avoid Overapplication: Excessive use may lead to nutrient toxicity or reduced effectiveness.
2. Prevent Direct Contact: Avoid spraying stems or roots to minimize phytotoxicity.
3. Optimal Weather: Apply on clear, windless days to reduce evaporation and improve absorption.
4. Soil Moisture: In dry conditions, pair foliar spraying with irrigation to prevent dehydration.

foliar fertilization is a practical tool for addressing tomato leaf curling and boosting growth. By selecting appropriate fertilizers, timing applications correctly, and following safety guidelines, farmers can promote healthy tomato development and maximize yields.
