Basal application of fertilizer – Excessive fertilization of poorly decomposed compost or organic fertilizer is the main cause of nutrient imbalance and salt accumulation.

Gas stress caused by premature organic matter is fatal to crops.

Manage to ensure consistent supply of fertilizer.

⇒ Soil application with CERES (4-2-1+70% organic matter) 1000KG/1ha.

⇒ Soil application with ONE PRO 952 900KG/1ha 

⇒ Soil application with NUTRI POWER 100KG/1ha.

 

Managing after planting – Manage nutrients without additional fertilization.

 

1. Right before or after 30 days after planting: Protuberance appearance period (Appears overground)

⇒ Head drenching with BIG HEALTH 1000x to promote cell division.

 

2. Right before or after 40 days after planting: Initial period of tuber formation

⇒ Foliar spraying with BLUB UP 1000x to promote tuber formation and creeping stem increase.

 

3. Right before or after 50 days after planting: Creeping stem increase ends

⇒ Irrigation with CALSTAR GOLD 1000x + foliar spraying with POLYCAB 1000x to increase the calcium absorption amount during initial period of tuber formation.

 

4. Right before or after 60 days after planting: Tuber enlargement

⇒ Foliar spraying with DOUBLE K 250x for vigorous bulb enlargement.

 

5. Right before or after 70 days after planting: Tuber enlargement

⇒ Irrigation with TOP PLANT PKCAB 1000x

6. Right before or after 95 days after planting: Harvest period

⇒ Foliar spraying with BIG BULB 1000x to enlarge the bulb by having all nutrients move to the blub before harvesting.
