Multi-K = 13-0-46 (Potassium Nitrate).
Calcium should be applied according to soil analysis results.
Foliar recommendations
- Initiation of flowering: Foliar sprays with Poly-Feed 11-44-11, at 0.5%, 3-4 sprays in 10 days intervals.
- Boost yield and quality: Foliar sprays with Multi-K, at 1-2%, 4-6 sprays after fruit set in 10-15 days intervals.
The following recommendations should be adjusted according to local conditions and experience. All Haifa products are compatible with most pesticides and plant nutrients, more than one chemical can be sprayed simultaneously in a single application.
