Eggplant Yield Increase and Color Improvement

Through the Agrology Success Stories in Greece and abroad, it is proven that the superior quality and integrated innovative technologies of the Agrology Specialized Nutrition products make the difference in crops from the very first applications!

Our ultimate goal is to demonstrate that the Agrology Specialized Nutrition Programs constitute a profitable investment for producers, as the financial benefits more than cover the cost of the additional applications!

One such Success Story on Greenhouse Nadia Eggplants (SS 2020_56_GR) was carried out in Ierapetra in collaboration with the agricultural store of Tzanis Emmanouil, during the agricultural season 2020-21. Throughout the applications, there was continuous guidance and technical support to the producer, both from the specialized staff of the technical department of Agrology, and the collaborating agricultural supplies store.

The crop was divided into 2 sections. One section was named Control and the second was named Agrology Program.  In both, the producer proceeded with the same cultivation care and implemented the exact same scheme of plant protection and nutrition – fertilization. However, in the Agrology Section, the producer implemented additional interventions using the Specialized and Innovative Products of Agrology, aiming to Eggplant Yield Increase .

14 days post-harvest:

  • Agrology: 10% non-marketable fruits
  • Control: 20% non-marketable fruits

21 days post-harvest:

  • Agrology: 65% non-marketable fruits
  • Control: Total non-marketable fruits

Fruit Consistency (maintaining at room temperature)

14 days post-harvest:

  • Small Increase in the consistency of marketable fruits of the Agrology section compared to the Control (estimated only on fruits without postharvest sepsis)

21 days post-harvest:

  • Agrology: Satisfactory flesh consistency of fruits that did not show post-harvest sepsis (76.7th Shore)
  • Control: (all fruits were non-marketable due to post-harvest sepsis)
