Effect Of The Application Of Metalosate® Products On Yield And Fruit Quality Of Strawberries, Variety 'Sonata', In Denmark

Introduction
 
The aim of this trial was to demonstrate the efficacy of the Metalosate products in a well designed program. The purpose of this micronutrient program was to increase the weight, firmness, and sugar content of the berries.
 
Metalosate Crop-Up® was used to supply a range of minerals to the plant at the flowering stage, which is considered a critical stage with high stress to the plant. The use of Metalosate Calcium and Metalosate Potassium from the onset of flowering until harvest was to help reduce flower drop, and later on to enhance firmness and increase sugar content in the fruit. Earlier studies were performed in the USA on melons using Metalosate Calcium and Metalosate Potassium to improve fruit quality.
 
Materials and Methods
 
The entire field (treated and control sides) was fertilized first with manganese sulfate. The treated side was then fertilized with Metalosate products according to the program outlined in Table 1.
 

Results and Discussion                                                               Figure 1. Strawberries

The average weight per berry and Brix levels were measured from the first, third and fourth picks of the berries.  Due to weather constraints the second pick was completed by the grower without the researchers present. 
 
The Brix percent readings in all three recorded picks were statistically significantly higher in the Metalosate treated berries when compared to the control berries.  In the first and third picking the Metalosate treated berries statistically yielded significantly more berries when compared to the control berries. 
 
Weight 
 
  • The first picking yielded more marketable berries with a weight heavier than 8 grams (0.2 oz), which is the minimum weight accepted.
  • In the first picking, almost 90% of the treated berries weighed above 12 grams (0.4 oz).  The optimum marketable weight is between 12 and 25 grams (0.4 – 0.9 oz).
  • In the fourth picking, the treated side had 10% less berries with weights below 8 grams (0.2 oz).  Almost 75% of the berries were between 8 and 25 grams (0.2 and 0.9 oz), very desirable weights.

Brix

  • The Brix values were higher for the treated plants in all the pickings.  This is important for the early picked strawberries which have a tendency to have lower Brix values.
  • Higher price for the early strawberries.
