PF = Polyfeed drip of the different analyses indicated.
Multi-K = 13-0-46 (Potassium nitrate, soluble)
Note: Rate of application should be adjusted according to soil and leaf analysis.
Additional to the fertilization by fertigation, foliar feeding is recommended as complementary treatments, as follows:

Fertilizers |
Rate |
||
| 2 months after harvest | Magnisal | .4 - 0.5% by 2-3 sprays in 2 weeks intervals | Induction of new leaves, Improved health |
| 2 months before flowering | MKP or MAP | 0.5% by 3-5 sprays in 2 weeks intervals | Flower initiation |
| 1 month after fruit set | Multi-K + Magnisal | 1-2%, by 6-8 sprays in 2 weeks intervals | Increases fruit size & shape |
| 0.25-0.5% by 2-4 sprays in 2 weeks intervals | Increases total solids in fruit | ||
Magnisal = Magnesium nitrate, 11-0-0 +15.8 MgO, a fully soluble fertilizer.
MKP = mono-potassium phosphate, 0-52-34, a fully soluble fertilizer.
MAP = mono-ammonium phosphate, 12-61-0, a fully soluble fertilizer.
