Agrology Success Stories: Production Increase and Earlier Harvest in Greenhouse Tomato

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 greenhouse tomatoes (SS 2018_7_GR) in 2018, in collaboration with “Geoponiki Marathona”, an important agrodealer and part of our NutriMaster® network in Greece. Throughout the whole process, the grower benefited from the continuous guidance and support offered by both Agrology’s Technical Department, and “Geoponiki Marathona”.

Initially the crop area 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

The Program was based in the  application of Specialized and Innovative Plant Nutrition Products, Gravital® Force & XGel® Ruby. Timing of the applications was essential in maximizing the  agronomic benefits of the program.

The objectives of this Success Story were as follows:

  1. Production increase in tomato
  2. Earlier maturation and harvest
  3. Uniform distribution of production with no major fluctuations between successive cuts
  4. Acquisition of significant economic benefits by the producer, through the achievement of the previous objectives.

Investment – Producer’s Benefit

The increase of production by 7900kg / ha (or 25,5%) and the 10-day earlier harvest, contributed to the increase of the producer’s income by 5.920,50 € / ha (average selling price of the Central Vegetable Market of Athens in the period May-June 2018: € 0.75 / Kg or € 10.950.00 / ha with retail prices on the local market € 1.50 / kg, price from personal communication with sellers of public markets).
