Abstract
Microclimate created in the psamo-pelitic soils in southern Oltenia, offers great conditions for growth and development of sweet potato (Ipomoea batatas) which is a thermophilic plant specific tropical and subtropical areas. The results obtained during 2013-2015 from Dabuleni, Development Research Center for Plants Crops on Sands, emphasizes productions between 19221 -21634 kg / ha, depending on the size space nutrition and variety cultivated. Those two factors in the study have significantly influenced the conduct from plant physiological processes. The highest value from plant photosynthesis rate (28.81 micromoles CO2 / m2 / s) was recorded at 11 am, at a density of 40,000 plants / ha, when sweet potato plant has lost through sweating about 5.69 millimoles H2O / m2 / s
