National natural conditions strongly influence the floristic structure of meadows, creating a wide range of meadow types and formations. This diversity of species ensures the functionality, efficiency and resilience of the ecological balance within these natural ecosystems. The objective of this study was to determine the effect of the applied management on the phytodiversity of a Dichanthium ischaemum permanent meadow in the Moldavian forest-steppe. The experimental factor was: fertilization with seven treatments: T1- unfertilized (control), T2- N50P50 kg/ha annually, T3- N75P75 kg/ha annually, T4- N100P100 kg/ha annually, T5-10 t/ha sheep manure annually, T6-20 t/ha annually and T7-30 t/ha annually sheep manure
applied at two years. The applied fertilizers influenced the floristic composition, producing appreciable, quantitative and qualitative changes in the vegetal cover. The dominance and frequency of the species, as well as the variation of the Shannon diversity index, were largely influenced by the amount of mineral NP, the amount of manure, but also by the number of years of the fertilization period.
