Studies conducted on maize, located on sandy soils in southern Oltenia, were focused on the influence of root and foliar fertilization, correlated with underground irrigation on soil moisture dynamics during the growing season also on morphological, physiological and productivity parameters of the plant. Soil moisture determinations revealed a moisture deficit on the depth of 0-20 cm, between -105.2-31.2 m3/ha, at the watering minimum limit of 1/3 of active humidity range (a.h.r). and -90.53... 86.5 m3/ha, at the limit of 1/2 of a.h.r, deficit more pronounced during July, in the phase of appearance of the panicle until the formation of grains on cobs, accentuate the importance of irrigation on sandy soils. Maize best exploited the microclimate achieved by underground irrigation at the minimum limit of 1/2 in the range of active soil moisture, by fertilizing with N150P80K80 + foliar fertilization with ALBIT product at a dose of 40 ml/ha, recording a maximum yield of 9089 kg/ha, with a distinctly significant difference of 3919 kg/ha, compared to the non-fertilized variant.
