biofertilizer, Chlorella sorokiniana UTEX 1230, soil sandy.
In the context of climate change, the use of microalgae is an alternative to meet the requirements of agriculture, food and renewable energy. A major area of application is the use of microalgae as biofertilizers in agriculture.
The aim of this paper is to study the influence of the application of Chlorella sorokiniana UTEX 1230 inoculum on the evolution of soil chemical composition, as well as the ability of microalgae, as a biofertilizer, on the growth and development of tomato plants, including the influence on plant physiological indices. Ground determinations, at 60 days after application of Chlorella sorokiniana UTEX 1230 inoculum indicated higher values of nitrogen, phosphorus, potassium and organic carbon content in the soil, The results regarding the growth and development of the plants obtained in the protected area (solar greenhouse), for the Romec 554j tomato variety showed differences between the variants studied. The Romec 554j tomato variety recorded a higher rate of photosynthesis in the version treated with the inoculum of Chlorella sorokiniana UTEX 1230, compared to the control version and the technologically fertilized version (12,66 µmol CO2 / m2 / s, compared to 11,82 µmol CO2 / m2 / s in the control version and 12,48 µmol CO2 / m2 / s in the technologically fertilized version), but the values were not statistically assured.
