MAXIMUM PROTECTION AGAINST GRAINY FLESH AND BURNT LOBES IN DURIAN

NPK CON CO SOP 100% Potassium Sulphate ensures golden, dry, and fragrant durian flesh, reducing grainy flesh and burnt lobes while improving yield and fruit quality.

NPK CON CO SOP - Solution to prevent grainy flesh and burnt lobes in durian

During fruit development, durian often suffers from grainy flesh and burnt lobes, especially when the trees are sensitive to chlorine found in many NPK products containing MOP. This issue not only reduces commercial value but also directly affects fruit yield and quality. To minimize this risk, farmers should use NPK CON CO SOP, a SOP-based fertilizer (Potassium Sulphate) specifically formulated for durian, ensuring golden, dry, aromatic, and uniform fruit flesh.

NPK CON CO SOP completely eliminates harmful chlorine, uses 100% Potassium Sulphate, and is enriched with sulfur (S) to support essential oil synthesis, enhancing the durian’s characteristic aroma. Compared to common NPK with KCl, SOP does not salinize the soil, stabilizes pH, and is especially suitable for Eastern basalt red soils, which tend to acidify easily.

Popular NPK CON CO SOP formulas

Baconco designs SOP NPK formulas specifically for each fruiting stage, ensuring durian trees absorb sufficient nutrients while minimizing grainy flesh and burnt lobes:

• NPK CON CO 15-15-15+9S+0.05B – suitable for young fruits and weak trees.
• NPK CON CO 12-11-18+1.4Ca+5S+0.1Zn+0.1B – provides micronutrients and calcium for faster fruit growth and firmer lobes.
• NPK CON CO 12-12-17+5S+0.05B – supports optimal fruit size and golden flesh development.
• NPK CON CO 7-7-14+12S+7Ca+0.045B – for the final stage, promoting sugar accumulation and even ripening.

Each granule of NPK CON CO SOP is manufactured using Baconco’s proprietary technology, ensuring uniformity, rapid dissolution with light rain or irrigation, deep root absorption, minimal nutrient loss, and ease of application.

Outstanding advantages of NPK CON CO SOP

1. Prevents grainy flesh and burnt lobes: 100% Potassium Sulphate eliminates chlorine, protecting the fruit’s golden, dry flesh.
2. Enhances flavor: Sulfur (S) supports essential oil synthesis, producing rich and aromatic durian flesh.
3. Protects soil and roots: SOP does not salinize soil, stabilizes pH, suitable for red basalt soil and other acid-prone areas.
4. Uniform and fast-dissolving: Granules are consistent, easily applied by hand or machine, dissolving quickly for maximum nutrient uptake.
5. Stage-specific formulas: Baconco provides different formulas for each stage, from young fruit to the “flesh ripening” stage, ensuring even development and golden, aromatic flesh.

NPK CON CO SOP fertilization schedule for durian

To achieve golden, dry, aromatic flesh while minimizing grainy flesh and burnt lobes, fertilization is divided into three main stages:

Stage 1: Fruit Size of a Chicken Egg (30–45 Days After Fruit Set)

• Goal: Promote rapid fruit growth, green spines, and reduce physiological fruit drop.
• Products: NPK CON CO 15-15-15+9S+0.05B, NPK CON CO 12-11-18+1.4Ca+5S+0.1Zn+0.1B, or NPK CON CO 12-12-17+5S+0.05B.
• Dosage: 0.5–0.7 kg/tree, applied around the canopy, water immediately after application.
• Additional Note: Can spray COFOLI AMINO + COFOLI MAX 36 to enhance fruit roundness.

Stage 2: Rapid Fruit Development (60–70 Days After Fruit Set)

• Goal: Provide sufficient nutrients for maximum fruit size without stressing the tree.
• Products: NPK CON CO 15-15-15+9S+0.05B (for weak trees), NPK CON CO 12-11-18+1.4Ca+5S+0.1Zn+0.1B, or NPK CON CO 12-12-17+5S+0.05B.
• Dosage: 0.8–1 kg/tree per application.

Stage 3: “Flesh Ripening” Stage (20–30 Days Before Harvest)

• Goal: Transition from size increase to accumulation of dry matter and sugar, ensuring uniform ripening.
• Products: NPK CON CO 12-11-18+1.4Ca+5S+0.1Zn+0.1B, NPK CON CO 12-12-17+5S+0.05B, or NPK CON CO 7-7-14+12S+7Ca+0.045B.
• Dosage: 1–1.2 kg/tree per application.
• Additional Note: Spray COFOLI K300 to supplement easily absorbed organic potassium. If shoots emerge, treat immediately to avoid nutrient competition affecting fruit shape. KALIBO + COFOLI PK500 may be applied.

Conclusion

Using NPK CON CO SOP is the most effective solution for farmers aiming to achieve durian with golden, dry, and aromatic flesh while minimizing grainy flesh and burnt lobes. With diverse formulas, proprietary manufacturing technology, and stage-specific fertilization, NPK CON CO SOP improves fruit quality, increases commercial value, and protects soil health.

By selecting the right product and following proper application schedules, durian growers can ensure high yield, superior flavor, and market-standard fruit appearance.
