Effect
Increased produce quality
Increased nitrogen N use efficiency
Increased phosphorous P use efficiency
Increased potassium K use efficiency
Viva treated tomato, c.v. Ombeline F1 and Bostina F1 grown with 100 % NPK nutrition had on average a 9.6 % higher yield, leaves contained 9.7 % more chlorophyll and 23.3 % more carotenoids, fruits contained 79.7 % more total soluble proteins, had the same acidity, ascorbic acid and lycopeen content compared to the untreated control grown in the same conditions. Viva treated Tomato, c.v. Ombeline F1 and Bostina F1 grown with 60 % NPK nutrition had on average a 15 % higher yield, leaves contained 8.2 % more chlorophyll and 5.7 % less carotenoids, fruits contained 168 % more total soluble proteins and had the same acidity, ascorbic acid and lycopeen content compared to the untreated control grown in the same conditions.
