Example, to search for all recorded cases of biostimulant use on tomato mitigate effects of drought type: "tomato, drought"

MegaFol + Brexil-Zn + MC-Extra

Type: Mix of different types, Company: Valagro


Increased produce quality
Increased potassium K use efficiency

MegaFol+ Brexil-Zn+MC-Extra treated Almond, cv. Nonpareil, grown under adequate potassium levels had a 160 % bigger shoot leaf area, an equal shoot length, a higher number of leaves, a bigger leaf size, an equal trunk diameter and 14.7 % more branches (g) (not sign) compared to the untreated control. MegaFol+ Brexil-Zn+MC-Extra treated Almond, cv. Nonpareil, grown under low potassium levels had a bigger shoot leaf area, a bigger shoot length, more leaves per shoot, an equal trunk diameter and 25.6 % more branches (g) compared to the untreated control onder low potassium levels.
