Effect
Increased produce quality
No effect on potassium K use efficiency
GroZyme treated Almond, cv. Nonpareil, grown under adequate potassium levels had a 195 % bigger shoot leaf area, a bigger shoot length a higher number of leaves, a bigger leaf size, an equal trunk diameter and 5.3 % more branches (g) (not sign) compared to the untreated control. GroZyme treated Almond, cv. Nonpareil, grown under low potassium levels had an equal shoot leaf area, a bigger shoot length (not sign), more leaves per shoot (not sign), an equal trunk diameter and 13.2 % more branches (g) (not sign) compared to the untreated control onder low potassium levels.
