Haifa’s Nutrigation™ program increased raspberry yield and improved fruit quality

Successful raspberry crop is measured not only by yield amount, but also by the fruit quality, as post-harvest behavior of this soft fruit is a significant factor affecting grower’s revenue.    A trial was carried out in Zamora, Michoacán state (Mexico) to evaluate Haifa’s Nutrigation™ program for raspberry.  The results proved that nutritional program based on Poly-Feed and other Haifa’s water-soluble fertilizer results in higher yield and improved fruit quality.
Trial objective:  Evaluation of Haifa's Nutrigation™ program, compared to the common farmer’s practice
Location: Zamora, Michoacán, Mexico
Crop: Raspberry
Growing system: Soil greenhouse
Planting date: October 2021 
Product: Poly-Feed, Haifa Cal™ GG, Haifa Mag 
Adequate supply of calcium during the stages of berry development helps produce firmer fruits with longer shelf life. Haifa Cal™ GG is a preferable source of calcium, as it contains nitrogen in the form of nitrate (NO3-), which enriches plant nutrition and improves the efficiency of calcium uptake.
