Napa Cabbage Fertilization Point

 

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.

Calcium, boron, and sulfur fertilization is absolutely necessary.

Initial growth and development must be satisfactory for bulb formation to be substantial.

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

⇒ Soil application with ONE PRO 500 900KG/1ha

⇒ Soil application with NUTRI POWER 100KG/1ha

 

Additional Fertilizer -The demand for fertilizer is also highest at bulb formation time.

Stable provision of potassium and calcium is necessary.

⇒ Rooting and plasmodiophora brassicae prevention right after planting - Irrigation with THE ROOTS 20L/1ha.

⇒ 1st Additional Fertilizer: Bulb formation starting time (Before or after 25 days after planting) - Soil application with NK CALMA 300KG/1ha.

⇒ 2nd Additional Fertilizer: Before or after 20 days after 1st additional fertilization - Soil application with NK CALMA 300KG/1ha

⇒ 3rd Additional Fertilizer: Before or after 20 days after 2^nd additional fertilization - Soil application with NK CALMA 300KG/1ha

 

Physiological Disorders and Problems that Occur During Napa Cabbage Cultivation

 

1. Prevention and recovery of overgrowth when raising seedlings - Raising sturdy seedlings

⇒ After shoot comes out - Head drenching by diluting THE ROOTS 1000x

⇒ 3-7 days before transplanting – Foliar spraying with NO OVER GROWTH 2000x

 

2. When overgrowth is severe during bulb formation stage – Occurs due to excessive nitrogen

⇒ Foliar spraying with NO OVER GROWTH 2000x + BALANCE PRO 1000x

 

3. When leaf tip turns brown or inside turns soft – Occurs due to calcium deficiency

⇒ Foliar spraying with POLY CAB 1000x

 

4. When napa cabbage inner leaf etiolates or black speck phenomenon appears – Deficiency of microelement like iron and boron

⇒ Foliar spraying with COMBI Ⅰ 2000x

 

5. Prevent and solve dry damage due to drought

⇒ Foliar spraying with DSD-1 1000x

 

6. When snails and cabbage butterflies occur

⇒ Foliar spraying with SSR-1 (2) 1000x or JJB GOLD 1000x

 

7. Pest control of moth community – Pest control must be carried out before bulb formation

⇒ Foliar spraying with SSR-1 (2) 1000x or JJB GOLD 1000x

 

8. Prevention of soft rot, bacteriosis, and bottom rot when bulb formation starts

⇒ Foliar spraying with SSR ALL or MOLD OUT 1000x + POLY CAB 1000x

 

9. When controlling downy mildew, slime mold, lead spot, and Fusarium wilt

⇒ Foliar spraying with SSR ALL or MOLD OUT 1000x + LUK S 1000x
