In order to increase the degree of food security in the areas affected by thermohydric stress in Romania, the aim is to identify new species of plants that can optimally exploit the microclimate of the area, through their biological potential. The pedoclimatic conditions recorded in the southern part of Romania offer an optimal microclimate for the growth and development of the sweet potato plant (Ipomoea batatas), which is a thermophilic plant, specific to tropical and subtropical areas. Research carried out between 2020-2022 on the sandy soils of southern Oltenia, showed that the sweet potato genotype s studied behaved differently in terms of tuber quality, accumulating a total amount of dry matter between 27% for the variety JUHWANGMI and 46.98% in the variety HAYANMI, with a variety average of 35.35%. Obtaining competitive productions is influenced by the choice of the most suitable sweet potato genotype for the area of sandy soils in S-W Oltenia. The average production for the three years of the study showed values between 17804 kg/ha for the DCh 19/3 genotype and 53368 kg/ha for the DK 19/1 genotype.
