The variation of some vegetation indices of maize under the influence of mineral fertilization
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 indice...

| 520 | 3 | |a 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. | |
