Supplying the winter oil seed rape with the right amount of nutrients

Haifa's fertilization recommendation for winter oilseed rape, including the recommended fertilizers

Growing method: open field.
Plant density: 350,000-700,000 / Ha.
Expected yield: 3.5 Ton / Ha.

Main nutrients uptake (Kg/Ha)
N	P₂O₅	K₂O	SO₃	Mg	Mn
280-300	100	400	180	70	1.5

Nutrition recommendation

Top dressing:

I. First treatment should be applied at fall and early winter, from sowing to 8 leaves.

N	Ammonium nitrate
	Kg/Ha
60-70	180-210

II. Second treatment: Should be applied at winter, on onset of regrowth.

P₂O₅	MAP	K₂O	Multi-K	Mg	Magnisal
Kg/Ha		Kg/Ha		Kg/Ha
100	160	190	440	70	440

Multi-K = Potassium nitrate
MAP = Monoammonium phosphate
Magnisal = Magnesium nitrate

III. Third treatment: Should be applied 2-3 weeks later.

Nutrition requirement (Kg/Ha)			Recommended fertilizers (Kg/Ha)
N	SO₃	K₂O	AS	Multi-K
120	180	190	300	440

*AS = Ammonium sulfate. This specific fertilizer is important in order to supply the need in SO3.

Manganese need (see above) should be best supplied as a foliar spray. Can be part of Maneb treatments against leaf diseases.
Sulphur applied in early spring as a compound fertilizer containing sulphate will generally give immediate response when lacking.
