2、Optimizing Citrus Production: Practical Guidelines for Effective Foliar

In citrus production, the success of foliar fertilization depends on thoughtful integration into an overall nutrient management strategy. By tailoring foliar applications to orchard-specific needs and aligning them with crop development stages, growers can optimize tree health, improve fruit quality, and support resilience under challenging ...

3、(PDF) Combination of NPK fertilization and Foliar Application for

In this investigation, influence of foliar application of micronutrients (Zn, Cu and B) was studied on the improvement in photosynthetic and fruit yield attributes of citrus (Kinnow) plants.

Foliar Feed Your Trees

Although field research has shown that supplemental foliar feeding can increase yield by 10% to 25% compared with conventional soil fertilization, foliar fertilization should not be considered a substitute for a sound soil fertility program.

[Optimized nutrients management improved citrus yield and

Optimized fertilization management could synergistically improve citrus yield, fertilizer use efficiency, and fruit quality.

2026–2026 Florida Citrus Production Guide: Fertilizer

For over five decades, foliar fertilization of citrus has been recommended to correct zinc, manganese, boron, copper, and magnesium deficiencies. It is now common knowledge in agriculture that properly nourished crops may better tolerate insect pests and diseases.

FOLIAR FERTIUZATION IN CITRUS ~ A REVIEW

Foliar application of K preferably as KNO 3 has been found highly effective in reducing substantially the problem of creasing and puffing associated with citrus fruits.

Combination of NPK fertilization and Foliar Application for Increasing

The research aimed to obtain the best combination of NPK fertilizer dose and foliar application frequency for increasing the yield of citrus. The research was conducted from June 2019 to April 2020 at the Ex-farm belongs to Faculty of Agriculture, Jenderal Soedirman University.

Citrus Fertilizer Application Methods: Soil vs. Foliar Feeding

When used in combination, citrus fertilizer strategies that incorporate both methods — such as applying Sulforex 60 + Cu via foliar spray and Ugarit Multi via soil — result in superior nutrient balance and healthier trees.

Optimizing Citrus Production: Practical Guidelines for Effective Foliar

In citrus production, the success of foliar fertilization depends on thoughtful integration into an overall nutrient management strategy. By tailoring foliar applications to orchard-specific needs and aligning them with crop development stages, growers can optimize tree health, improve fruit quality, and support resilience under challenging ...

Combining citrus bagging with foliar fertilization is a common integrated management practice in modern agriculture, aimed at improving fruit quality, yield, and stress resistance. Below is a detailed analysis of its effects:

I. Enhancing Fruit Quality

1. Reducing Pest and Disease Occurrence

• Physical Isolation: Bagging physically prevents external pests (e.g., aphids, red spiders) from directly contacting the fruit, lowering damage rates.
• Chemical Protection: While bagging does not replace chemical pesticides, it reduces the frequency and dosage of pesticide applications, minimizing chemical damage to the peel.

2. Improving Appearance and Color

• Sunlight Protection: Prolonged sun exposure during growth can cause sunburn on fruit surfaces, affecting appearance. Bagging shields fruits from direct sunlight, preserving better skin tone.
• Skin Protection: The peel is vulnerable to mechanical injuries during maturation. Bagging partially safeguards the peel, reducing physical damage.

II. Increasing Fruit Yield

1. Promoting Fruit Enlargement

• Moisture Retention: Bagged fruits retain soil moisture more effectively, supporting fruit expansion.
• Nutrient Conservation: Bagging minimizes nutrient loss caused by wind, rain, or other environmental factors, aiding fruit growth.

2. Improving Fruit Set

• Reducing Physiological Drop: Bagging decreases fruit drop due to pests, diseases, or mechanical injuries, improving set rates.
• Enhancing Pollination: Bagging concentrates pollen near pistils, facilitating pollination and boosting fruit set.

III. Strengthening Stress Resistance

1. Cold Resistance

• Frost Mitigation: In cold regions, bagged fruits maintain higher temperatures than uncovered ones, delaying frost damage.
• Cellular Protection: Bagging tightens cellular structures, enhancing resilience against low-temperature stress.

2. Drought Resistance

• Water Balance: Bagging helps fruits retain soil moisture, alleviating drought impacts.
• Disease Prevention: By limiting direct environmental contact, bagging reduces pathogen invasion, mitigating drought-related issues.

IV. Economic Cost-Benefit Analysis

1. Pesticide Cost Savings

• Reduced Pesticides: Bagging lowers pesticide usage frequency and volume, cutting costs.
• Efficiency Gains: Fewer pests and diseases optimize resource use, reducing economic losses.

2. Economic Benefits

• Higher Market Value: Improved fruit quality raises market prices, increasing farmer revenue.
• Loss Prevention: Bagging reduces damage from pests and diseases, minimizing yield losses.

Combining citrus bagging with foliar fertilization is an effective strategy to enhance fruit quality, yield, and stress resistance. it should complement—not replace—other practices like rational fertilization and pruning. For optimal results, farmers should tailor these techniques to specific conditions.
