Effect
Trainer treated Tomato, cv. Akyra/Sir Elyan, grown in an unheated greenhouse was on average 7.2 % taller, had on average 13 % more leafs, 16.4 % more shoot biomass, a 14.8 % higher marketable yield, 15.8 % heavier marketable fruits, 6.8 % more marketable fruits, leafs contained 8.6 % more N, 25 % more P, 20.6 % more S, 9.6 % more K, 13.1 % more Ca, 28.7 % more Mg, 9.7 % less Na, fruits had on average a 0.7 % lower shape index and contained on average 1 % more dry matter %, 8.7 % more total soluble solids, a 0.6 % higher pH, 12.6 % less P, 5.5 % more K, 8.8 % more Ca, 21.8 % more Mg, 19.5 % less Na, had a 125.9 % higher antioxidant capacity and containd 1.4 % more total phenols and 24.6 % more ascorbic acids compared to the untreated control. The lowest dose had only a significant effect on the mean fruit weight, total soluble solids content of fruits and the antioxidant capacity. The highest dose had a significant effect on most parameters with an exception of the number of fruits, the S, Ca and Na content of leafs, the shape index, DM%, pH, P, Ca and Na content and total phenols of fruits. There wasn't a significant interaction between the cultivar and biostimulant for plant height, leaf number, shoot biomass or marketable yield.
