Physiological Indicators Study Involved in Productivity Increasing in Tomato

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 (cm 2 ); 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 f rom SC Doradda SRL.
