Better productivity and higher strawberry yield with Haifa’s combination of CRF and Nutrigaion™

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)
