The conveyed experiment sought to test the effect of a novel biostimulant Albit-BR, on the growth, fruit yield, and quality traits of tomato (Solanum lycopersicum L.). The experiment took place in 2024 in the Federal State Budgetary Scientific Institution, Federal Scientific Vegetable Center, VNIISSOK, Moscow Region, Russia. The field layout had a randomized complete block design with a factorial arrangement of two factors replicated thrice. The first factor comprised four tomato cultivars (Malets, Revansh, Talisman, and Fonaric), while the second factor included seven different doses of the biostimulant Albit-BR (0.1, 0.5, 1, 2.5, 5, 10, and 50 L/ha) in comparison with non-treated plants (control). The results revealed the biostimulant Albit-BR application with different levels on tomato cultivars has shown significantly better effects on the growth, fruit yield, and quality parameters. The cultivar Malets treated with Albit-BR (2.5 L/ha) produced the highest yield (96.76 t/ha). Furthermore, the same cultivar treated with the biostimulant at 5 L/ha showed the maximum values of bioactive compounds—lycopene (23.02 mg/100 g) and beta-carotene (4.24 mg/100 g). Thus, the current findings indicated that the aforementioned biostimulant at 2.5 to 5 L/ha are required to be applied on tomato plants to improve its production potential with reasonably better quality.

The interaction of different tomato (S. lycopersicum L.) cultivars with various levels of the biostimulant Albit-BR enunciated significant differences for growth, fruit yield, and the majority of the studied quality parameters.
