Sažetak
Biostimulators can be used in order to stabilise plant growth in even unfavourable climate conditions or fluctuating conditions in the rhizosphere and they stimulate the process of the formation of plant-organs making the plants resistant to diseases and viruses. In our investigations with tomato plants, liquid substances based on different organic compounds such as lignite coal (Humates), waste of food production (Lactate), algeas (Megafol), plant-based substances (Čudomiks, ) and microorganisms such as Bacillus subtilis were used as biostimulators. The effects of biostimulators were investigated in tomato soilless cultivation, cv. Ferrari RZ, in the greenhouse of the experimental station in Berlin. Humates, lactates, and B. subtilis were added to the nutrient solution, single or mixed and well sprayed on the leaves. Humates improved plant growth even when the EC was very high. In the case of extreme pH values of 4.5 or 7.5 better growth parameters were recorded when lactate had been added to the nutrient solution. In some cases, the development of tomato plants was also enhanced by combinations of humates, lactates, and B. subtilis. The field experiment was carried out on greyred soil in the valley of the river Raša (Istria). Biostimulators were applied on indeterminate, high beef tomato variety ‘Signora F1’ with a training system on one or two branches. PE mulch foil, fertigation, and trellis were used on the plantation. The influence of the triple treatment on fruit number, individual fruit weight, yield distribution, time of disease onset, and branch length was examined. The results of the study show that growing with two side shoots and treating with Megafol is the superior combination in terms of yield. On the other hand, the cultivation form with one side shoot in combination with Megafol leads to a better distribution of yields.
