This research aims to provide a novel strategy for developing an optimal fertilization approach that enhances the quality of passion fruit while improving soil quality, thereby contributing to agricultural sustainability.

Complete Fertilization Techniques for Passion Fruit

After each flowering and fruit setting (about once every 15-20 days), use phosphorus and potassium fertilizer as the main fertilizer. Pay attention to the supplement of middle and trace elements such as calcium and magnesium. It is recommended to mix with water and spray it in drought.

Passion fruit (also known as Passiflora or granadilla) is a tropical fruit cherished for its unique flavor and rich nutritional profile. Potassium, an essential micronutrient for plant growth, plays a critical role in maintaining normal physiological functions. Timely potassium supplementation during passion fruit development can promote healthy growth, enhance fruit quality, and improve stress resistance. Below is a detailed analysis of the optimal timing for potassium fertilization:

1. Growth Stages and Potassium Requirements

Passion fruit undergoes multiple growth stages, with varying potassium demands:

• Seedling Stage: Requires moderate potassium to support root development.
• Flowering and Fruiting Stage: Demands higher potassium levels for flower bud formation, fruit expansion, and sugar accumulation.

Key Periods for Fertilization: Focus on the seedling stage and flowering/fruiting stage.

2. Potassium Application During the Seedling Stage

The seedling stage is critical for root system establishment. Proper potassium use boosts root growth and nutrient uptake.

Key Considerations:

1. Timing: Apply within the first month post-planting to promote root development. Use high-nitrogen, low-phosphorus, low-potassium compound fertilizer initially.
2. Dosage: 5–10 kg of compound fertilizer per mu (≈667 m²), adjusted based on soil fertility and plant health.
3. Method: Apply via furrows or holes around the base, ensuring even distribution.

3. Potassium Application During Flowering and Fruiting

This stage determines fruit size, color, and yield. Adequate potassium enhances fruit quality and sweetness.

Key Considerations:

1. Timing: Apply approximately 1 month after flowering to support fruit enlargement and coloring.
2. Dosage: 10–20 kg of potassium fertilizer per mu, depending on plant vigor and soil conditions.
3. Method: Use circular or radial furrows around plants for precise application.

4. Selection of Potassium Fertilizers

Choose formulations based on soil type and growth stage:

• Potassium Sulfate: Suitable for acidic soils; counteracts excessive acidity.
• Potassium Nitrate: Ideal for neutral/alkaline soils; provides balanced N-P-K.
• Potassium Chloride: Use for neutral/alkaline soils; increases soil salinity.

5. Application Guidelines

Best Practices:

• Concentration: Dilute to 10% solution to avoid root burn.
• Timing: Apply in evening or cloudy weather to prevent heat-induced damage.
• Dosage Control: Adjust based on soil tests and plant response to avoid over/under-fertilization.

6. Complementary Measures

Enhance potassium uptake with:

• Irrigation: Maintain moist soil without waterlogging.
• Pest Management: Reduce nutrient loss by controlling diseases and pests.
• Pruning: Remove weak/diseased branches to improve airflow and light penetration.
• Balanced Fertilization: Supplement with other nutrients (N, P) as needed.

7. Key Precautions

• Avoid Direct Root Contact: Apply fertilizer away from roots to prevent burning.
• Compatibility: Do not mix with strongly acidic/alkaline fertilizers (e.g., avoid combining with superphosphate).
• Environmental Factors: Avoid extreme weather during application.
• Intercropping: Ensure companion plants do not compete excessively for potassium.

The optimal periods for potassium fertilization in passion fruit are the seedling stage (first month) and flowering/fruiting stage (1 month post-flowering). By adhering to proper timing, dosage, and methods, growers can maximize yields, improve fruit quality, and strengthen plant resilience.
