Yield Increase in Table Grapes

Through Agrology Success Stories in Greece and Abroad, it is proven that the superior quality and integrated innovative technologies of Agrology’s Functional Crop Nutrition® products, make a difference in crops from the very first applications!

Our goal is to demonstrate that Agrology’s Specialized Nutrition Programs are a profitable investment for farmers, as the financial benefits exceed the extra cost of supplemental applications!

One such Success Story was carried out in Table Grapes, variety Italia (SS 2021_209_GR) in 2021, in collaboration with the Commercial Store of Agricultural Supplies and NutriMaster® Balikas Andreas & Co. JP, in the region of Kavala. Throughout the process, the farmer benefited from the continuous guidance and support offered by Agrology’s Technical Department and the collaborating agricultural store of Mr. Balikas.

The vineyard was divided into two equal plots, one was used as the Control, while Agrology’s Program was applied to the other plot. In both plots, the farmer used the same plant protection and plant nutrition-fertilization program, apart from the additional applications with Agrology’s Specialized and Innovative Nutrition and Fertilization Products.
