Evapotranspiration in agricultural crops is represented by water losses (unproductive) by evaporation from the soil surface and consumption (productive) by transpiration of plants. This study will try to highlight the importance of evapotranspiration (potential and real) in assessing the water consumption of plants, this being an essential parameter, with a particularly important impact on the crops obtained. This study was performed by daily analysis of the evolution of potential evapotranspiration calculated by the Penman-Monteith method (FAO-56 PM), as well as the real evapotranspiration performed in winter wheat and unirrigated maize crops for soil on different depths, in weekly and monthly intervals during the agricultural year September 1st, 2019 - August 31st, 2020. The specialized data analyzed included meteorological parameters: minimum and maximum diurnal temperatures, wind speed, sunlight duration, relative air humidity, crop coefficient, recorded precipitation and soil moisture reserve during the vegetation period of field crops with the most significant share in Romania, respectively winter wheat and unirrigated maize.
