Broccoli displays the highest yield when cultivated in neutral soil. The ideal soil pH is pH 6.5 for inorganic soil and about 5.5 for organic soil.

 

If pH is lower than 5.5, utilization of phosphorus, potassium, sulfur, calcium, magnesium, and molybdenum is lowered and absorption of unexpected heavy metals like cadmium and aluminum occurs.

At the level in which soil pH is 6.5 or higher, iron, manganese, zinc, and copper can become deficient.

Plant after managing suitable acidity by checking the soil acidity.

 

Broccoli is a crop with very fast growth that is harvested within 9 weeks to 13 weeks after planting. Therefore, initial fertilizer management is very important.

 

Broccoli 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.

Comprehensive fertilization and balanced fertilization are needed.

⇒ Fertilize with DOL LIME if soil acidity is below 6.0 (Fertilize the appropriate amount by observing the acidity)

⇒ 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 right after planting - Irrigation with THE ROOTS 20L/1ha

⇒ 1^st Additional Fertilizer: Bulb formation starting time (Before or after 25 days after planting) - Soil application with NK CALMA 200KG/1ha.

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

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

⇒ 4^th Additional Fertilizer: Before or after 10 days after 3^rd additional fertilization – Foliar spraying with DOUBLE PK 250x

 

Physiological Disorders and Problems that Occur During Broccoli Cultivation

 

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

⇒ After shoot comes out – Head drenching with SEAWEED F 500x

⇒ Before transplanting – Foliar spraying with NO OVERGROWTH 2000x

 

2. Prevent soft rot and bottom rot when bulb formation starts

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

 

3. Flower etiolation and browning occurs.

⇒ Foliar spraying with COMBI Ⅰ 2000x + LUK S 500x

 

4. Stem or the interior of broccoli becomes empty.

⇒ Foliar spraying with COMBI Ⅰ 2000x+ POLYCAB 500x
