Increase of Grapes Yield and Quality

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 for the wine grape of the Roditis variety (SS 2020_108_GR) was carried out in collaboration with the Agricultural Supplies Store of Antonis Lianos, during the 2020 Season. 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 vineyard was divided into 2 equal 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 to Increase Grapes Yield and Quality.
