Agrology Success Stories: Increase Olive Fruit Size & Weight

Agrology’s Success Stories demonstrate the ability of Agrology’s Specialty Plant Nutrition Products to make a difference even from the very first application!

Our aim is to show that Agrology’s Nutrition Programs are a profitable investment for the grower because their economic benefits far outstrip the cost of the complementary applications!

One such Success Story was carried out in table olives (SS 2018_14_GR) in 2018, in collaboration with Mr. Yomatari Dimokrati, a member of Agrology’s Nutrimaster®  network. Throughout the whole process, the grower benefited from the continuous guidance and support offered by both Agrology’s Technical Department, and Mr. Yomataris’.

Initially the olive grove was divided into two equal plots, that consisted the 2 treatments of the Success Story. One was used as the Control plot, while Agrology’s Program was used in the second. In both treatments, the producer made use of same plant protection and plant nutrition – fertilization program. Agrology’s Specialized and Innovative Nutrition and Fertilization Products application was complementary in the trial plot.

Success Story Goals

By using Specialty Plant Nutrition Products during specific growth stages of olives growing, the producer can achieve a significant improvement in the quality characteristics of his crop.

The Program included the implementation of Specialized and Innovative Plant Nutrition Products, more specifically, Gravital® Energy, Nodius® F-Kin, XGel® Sapphire, XGel® Emerald and XGel® Ruby. Moreover, the implementation took place during certain stages of olives growth and the producer to achieve significant agronomic benefits.

The Objectives of this Success Story were as follows:

  1. Increase in Olive Fruit Size & Weight
  2. Increase the percentage of 1st Grade fruits

Besides the above supplementary applications, the farmer applied the same Fertilization/ Nutrition and Plant protection program, in both treatments (Control + Agrology Program) throughout the growing season.

Success Story Results

Measurements on both plots revealed impressive results in the Agrology treatment. Specifically, the results were as follows:

  • Increase in fruit weight: + 34% (+2.5 gr / fruit)

The producer confirmed the results of sampling in practice by the producer himself in the early stages of harvesting and while delivering the fruit to the ordering offices. The difference observed in the Agrology Program was 30-50 olives per kilogram above the Control. The first harvest hands were made separately for the two pieces by the producer.
