The aim of the experiments was to show the effects of plant growth promoting rhizobacteria on the yield, dry matter and vitamin C content of processing tomato during different irrigation treatments, and measuring the chlorophyll fluorescence during the ripening and development stages. According to the results, none of the bacterial treatments had a statistical effect on the quantity and quality of the tomato and on the chlorophyll fluorescence, only the irrigation. Further studies are needed.application/pdfCopyright (c) 2020 Acta Agraria Debreceniensishttps://creativecommons.org/licenses/by/4.0/Vitamin CBrixchlorophyll fluorescenceinfo:eu-repo/semantics/article
