Abstract


The research objectives were to study the influence of fertilizers based on carbon dioxide on the main physiological indices involved in developing tomato bio-productivity: plant height (cm); leaf area (cm2); total quantity of chlorophyll (SPAD units); photosynthesis intensity (ppm CO2); determination of dry matter from leaves (%) and yields per plant (kg). The biological material used was the San Pierre variety from SC Doradda SRL.
