Total Yield Increase in Table Grapes

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 in Table Grapes of the Italia variety (SS 2021_209_GR) took place in Platanotopos Kavala, in collaboration with the store and NutriMaster® Balikas Andreas & Co. JP, during the 2021 Agricultural 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, targeting a yield increase in table grapes.

Proof Results

After the samplings from both sections –Control and Agrology-, the necessary measurements were made on table grapes and it was observed that the Agrology Programs generated impressive results for the benefit of the producer.

More specifically, the results were the following:

Total Yield Increase in Table Grapes  by 8.4%

  • Agrology: 3260 kg/1,000 sq.m.
  • Control: 3008 kg/1,000 sq.m.
Picture 2. Yield (kg/1,000 sq.m.) With the implementation of the Agrology Program, an increase in the total production by 252 kg/1,000 sq.m. (+8.4%) was achieved, compared to the Control.

Increase of Length of Bunch by 6.5%

  • Agrology: 25.3 cm
  • Control: 23.8 cm
Picture 3. Length of Bunch. With the implementation of the Agrology Program, there was a production increase by 1.54% (+6.5%), compared to the Control.

Increase of Weight of Bunch by 18.4%

  • Agrology: 602.22 gr
  • Control: 508.78 gr
Picture 4. Weight of Bunch. With the implementation of the Agrology Program, there was an increase in the weight of the Bunch by 93.4 gr (+18.4%), compared to the Control.

Grape Size Increase

  • Agrology: Top
  • Control: Bottom
Picture 5. Size of grape: By applying the Agrology program (top), there was an increase in the size of the Grape, compared to the Control (bottom)

Increase of Weight of the Grape by 20.4%

  • Agrology: 9.63 gr
  • Control: 8.00 gr
Picture 6. Weight of Grape. With the implementation of the Agrology Program, there was an increase in the weight of the grapes by 1.63 gr (+20.4%), compared to the Control.
