A complete recommendation for the fertilization of pepper plants

Find out what are the fertilizers that will give you the best results, regarding the different growing medium

I. Growing method: greenhouses / tunnels, on soil.
Plant density: 40,000-42,000 / Ha.
Expected yield: 50-70 Ton/Ha, depending on variety.

Macronutrients uptake (Kg/Ha)
N	P₂O₅	K₂O	CaO	MgO
200-300	150-200	350-500	180-200	80-100

Base dressing:

N	AS*	P₂O₅	K₂O	MKP**
Kg/Ha		Kg/Ha		Kg/Ha
63	300	180	120	350

* AS = Ammonium Sulphate
** MKP = Mono-Potassium Phosphate (0-52-34), is the source of P₂O₅ and K₂O

Growth stage	Nutrition requirement (Kg/Ha/day)			Recommended fertilizer (Kg/Ha/day)
Growth stage	N	P₂O₅	K₂O	Poly-Feed*	Multi-K	Haifa MAP*	AN	MKP*
1st two weeks	1	1	1	5.5				2
1st two weeks - flowering	1	3.5	2.2				3	6.5
flowering - fruit-set	1	3.5	2.2				3	6.5
fruit-set - harvest	2.5-3	2.3	3.2		7	3.2	3.5-4

Poly-Feed* = 19-19-19
Multi-K* = Potassium nitrate (13-0-46)
Haifa MAP* = Mono-Ammonium Phosphate (12-61-0)
* MKP = Mono-Potassium Phosphate (0-52-34)

II. Growing medium: Open field.
Soil type: Light soil.
Plant population: 30,000-35,000 Plants/Ha.
Expected yield: 80-100 T/Ha.

N	P₂O₅	K₂O
---------------- Kg/Ha -----------------
150	100-120	180-200

The rates are based on the assumption that 10% of the N and K and the total amount of P₂O₅ will be applied as base-dressing.

Nutrient requirements Kg/Ha			Recommended fertilizers Kg/Ha
N	P₂O₅	K₂O	Multi-K	SSP	AN
15-20	100-120	18-20	40-43	526-630	30-42

Growth stage	Nutrient requirements Kg/Ha		Recommended fertilizers Kg/Ha
Growth stage	N	K₂O	Multi-K	AN
Germin. Flowering	25-30	45-50	100-110	35-46
Flowering - Fruit set	30-40	45-50	100-110	50-75
Fruit set - 1st harvest	40-50	36-40	80-85	90-114
2nd and 3rd harvest	40-50	36-40	80-85	90-114
Total	135-170	162-180	360-390	265-349

At least 50% of the total N should be NO₃-N

AN = Ammonium Nitrate (34%N)
SSP= Single Super Phosphate (19% P₂O₅)
