In the southern part of the Romanian Plain, a research was carried out over a period of 5 agricultural years (2016- 2021) regarding the evaluation of wheat crops, consisting of 7 premium varieties, on a surface of 110 ha. The NDVI index was used to assess the quality of management, the influence of climate change, which are in constant variation, on wheat crops and their ability to fix atmospheric carbon in the form of CO2. For analyzing the data obtained from the Sentinel-2 satellite, in order to make the NDVI periodically summing and, then, to establish the daily average during the vegetation period from spring to summer, the calculation of the correlations and of the complex functions in 2D were used. In the integrated amount, NDVI ranged between 110.06 in 2020, the driest year, and 124.79 in 2018, the most favorable year for wheat cultivation. Yields also fluctuated in direct proportion to NDVI values, from 2,100 to 6,700 kg of wheat/ha. The obtained results place the area in conditions of high risk to water and other climatic factors, risks that can be partially reduced by optimizing crop management.
