Watermelon Yield Increase with Gravital Energy

Through Research Programs in Greece and abroad, Agrology proved that the superior quality and integrated innovative technologies of the 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 Research Program on Watermelons was carried out in Velestino Magnesia, in collaboration with the University of Thessaly in 2019.

The researchers divided the crop in 2 sections. The name of the first section was Control and the second’s Agrology Program.  In the Agrology section, the complementary interventions used the Specialized Nutrition Product Gravital Energy, aiming to Watermelon Yield Increase.
