Transplanting of chili plants requires a balanced fertilizer, such as NPK 15-15-15, to promote growth. A high phosphorus and potassium fertilizer, like NPK 10-20-20, is applied two weeks after transplanting. In the flowering stage, potassium and calcium are needed for flower formation and fruit set.

Chilli Fertilizer Schedule: How and When to Apply Organically

Chili plants are heavy feeders and will benefit from being fertilized every other week. During the vegetative stage, use a high-nitrogen fertilizer to encourage leafy growth. Once the plant begins to flower, switch to a low-nitrogen fertilizer to promote blooming.

Efforts to increase chili production need fertilization through roots and leaf fertilization. The research aimed to obtain optimum intervals of NPK (nitrogen, phosphor, potassium) fertilization and kinds of foliar fertilizer for the growth and yield of chili.

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

Foliar fertilizer application after soil fertilization is an effective method to increase the contents of trace elements in crops and crop yield, and to improve the soil environment. However, the application of inorganic foliar fertilizer results in difficulties in nutrient absorption and migration in plants.

The results showed that most growth and quality traits were best improved by foliar application of Biomin aminochelate followed by Humifolin fertilizer.

Chili, a common vegetable and spice, is widely cherished for its pungent flavor. During its cultivation, rational fertilization and management are crucial to enhancing yield and quality. Foliar fertilizer, a nutrient solution sprayed directly onto plant leaves, effectively replenishes essential nutrients and promotes growth. whether foliar fertilization remains viable after chili plants begin fruiting requires analysis from multiple perspectives.

I. Chili’s Growth Stages and Timing for Foliar Fertilization

1. Early Growth Stage

• Nutritional Needs: Chili plants require abundant nitrogen during early growth to support leaf development and differentiation, laying the foundation for flower bud formation. Foliar sprays at this stage rapidly supply nutrients, fostering robust growth.
• Fertilizer Choice: High-nitrogen formulations like urea or potassium nitrate are recommended to accelerate growth.

2. Flower Bud Differentiation Stage

• Nutritional Adjustment: Phosphorus becomes critical during flower bud differentiation to promote bud formation and development. Spraying phosphorus-rich fertilizers (e.g., potassium dihydrogen phosphate) enhances fruit setting rates.
• Fertilizer Choice: Solutions containing moderate phosphorus, such as potassium dihydrogen phosphate, are ideal for bud development.

3. Fruit Ripening Stage

• Nutrient Supplementation: Maturation demands microelements and potassium to ensure fruit quality and taste. Foliar fertilization at this stage improves ripening and coloration.
• Fertilizer Choice: Borax or potassium sulfate formulations boost fruit texture and sweetness.

II. Effects and Precautions of Post-Fruiting Foliar Fertilization

1. Effectiveness

• Yield Increase: Foliar fertilization accelerates nutrient uptake, stimulating growth and increasing yields by over 10% compared to untreated plants.
• Quality Improvement: Boron-based sprays, for instance, enhance fruit firmness and sweetness, while optimizing color and flavor.

2. Key Precautions

• Avoid Overdosing: Excessive application may cause excessive vegetative growth or root damage. Limit dosage to ≤5 kg per mu (0.067 ha).
• Select Appropriate Formulations: Tailor fertilizers to growth stages and prioritize reputable products. For example, prioritize phosphorus-rich blends during budding.

III. Strategies for Post-Fruiting Foliar Fertilization

1. Fertilization Planning

• Balanced Application: Apply foliar fertilizer every 7–10 days post-fruiting, repeating 2–3 times.
• Integrate Organic and Synthetic Fertilizers: Combining decomposed manure with synthetic options improves efficiency and reduces environmental impact.

2. Application Techniques

• Uniform Coverage: Ensure thorough spraying on all leaf surfaces using foggers or manual tools.
• Weather Considerations: Avoid extreme heat, drought, or rain. Ideal timing includes cloudy mornings for optimal absorption.

3. Post-Application Management

• Monitor Plant Response: Track for signs of stress (e.g., leaf yellowing) and adjust strategies if needed.
• Soil Testing: Regularly assess soil fertility and pH. Amend deficiencies or imbalances promptly.

Foliar fertilization remains beneficial for chili plants after fruiting. To maximize results, select appropriate formulations, control dosages, and integrate with broader management practices. Scientific fertilization enhances both yield and quality, supporting sustainable agriculture.
