A trial in Mexico showed that nutritional program that combined Multicote™ and water-soluble fertilizers (Poly-Feed™, Haifa Cal™ and Haifa Mag™) improved productivity in strawberry, resulting in better yield.
Objective: Evaluation of the effect of Haifa’s nutrition program on phenological behavior and yield of strawberries, compared to the common farmer’s practice.
Crop: Strawberry, cv Veronica
Location: Michoacán, Mexico.
Observation dates: August 2022
Harvest: October-December 2022 (3 harvests)
Haifa program
Pre-planting immersion: 6 g/l Poly-Feed™ 12-43-12+ME + 2 g/l ammonium nitrate
At planting: Multicote™ Strawberry Mix (22-8-13), 5 gr/plant
Drenching 1+2: 10 g/l Poly-Feed™ 12-43-12+ME + 4 g/l ammonium nitrate
Nutrigation™ (kg/ha):
