Biostimulants
The wine grapes and table grapes you enjoy could be grown with less synthetic fertilizer if seaweed-based and amino acid sprays prove effective — meaning better-tasting fruit with a lighter environmental footprint.
Scientists wanted to know if spraying grapevines with natural products — one made from seaweed and one from amino acids (the building blocks of proteins) — would help the vines grow better and produce more grapes. They tested this on two different grape varieties to see if the results held up across types. This kind of research helps farmers find greener ways to boost harvests without relying so heavily on chemical fertilizers.
Key Findings
Seaweed extract was evaluated as a biostimulant on Vitis vinifera grapevines, a crop of major global agricultural importance
Two distinct grape cultivars were compared, allowing assessment of whether treatment effects are variety-dependent
Amino acid fertilizers were tested alongside seaweed extract, providing a multi-treatment comparison relevant to organic and sustainable viticulture
chevron_right Technical Summary
Researchers tested whether seaweed extract and amino acid fertilizers could improve the growth and fruit yield of two grapevine varieties. The study contributes to growing interest in biostimulants as sustainable alternatives or supplements to conventional synthetic fertilizers in viticulture.

Vitis (grapevine) is a genus of about 80 species of twining plants in the family Vitaceae. The genus consists of species predominantly from the Northern Hemisphere. It is economically important as the source of grapes, both for direct consumption of the fruit and for fermentation to produce wine....
