The present research studied the variation of foliar area and chlorophyll in maize under the influence of mineral fertilization. The fertilizers applied were nitrogen, in doses that varied from 0 to 200 kg a.s. ha-1 , and the PK complex in doses between 0 and 150 kg a.s. ha-1 . The vegetation indices were studied in the leaf opposite the ear, and the determinations were made during the silking stage. The foliar area varied between 513.88±16.47 cm2 in the control variant and 724.32±13.61 cm2 in the variant with P150K150N200. Chlorophyll values ranged from 30.74±0.89 to 55.93±0.73 SPAD units in the same variants. The experimental results present high degree of statistical certainty (p< 0.01; F >> F crit, for Alfa = 0.001). The interdependence identified between the vegetation indices and the fertilizer doses was revealed.
