The work describes the community of improved meadows that thrives on the elevated parts of alluvia and sometimes marshes, on the sites above the flooded areas. These stands were found and recorded in the sub- Pannonian and pre-Dinaric areas of Slovenia. The relevés were compared with other similar communities from the alliance Arrhenatherion Koch 1926 as well as some of the ecological characteristics. A new association named Triseto-Centaureetum macroptili ass. nova is here proposed. It was classified into alliance Arrhenatherion and order Arrhenatheretalia R. Tx 1931. The characters of the order Molinietalia Koch 1926 are also common, which reflects the transitional environmental conditions of those sites. The association thrives on deposits, predominantly on levees, where the soil is permeable for water. The material from these meadows, which are mown once to twice a year, is used for fodder and not for litter, which confirms their classification.Prispevek opisuje združbo intenzivno gojenih travnikov, ki uspeva na dvignjenih mestih aluvialnih nanosov in včasih močvirij, na rastiščih nad poplavljenimi predeli. Tovrstni sestoji so bili najdeni in popisani v subpanonskem in preddinarskem območju Slovenije. Vegetacijske popise, kot tudi nekatere ekološke značilnosti smo primerjali z drugimi podobnimi združbami iz zveze Arrhenatherion Koch 1926. Opisali smo novo travniško združbo z imenom Triseto-Centaureetum macroptili ass. nova. Asociacijo smo uvrstili v zvezo Arrhenatherion Koch 1926 in red Arrhenatheretalia R. Tx 1931. Pogoste so tudi značilnice reda Molinietalia Koch 1926, kar kaže na prehodne ekološke razmere teh rastišč. Asociacija uspeva na naplavinah, predvsem na nasipih, kjer so tla prepustna za vodo. Material iz teh travnikov, ki so košeni enkrat do dvakrat letno, uporabljajo za krmo in ne za steljo, kar potrjuje njihovo klasifikacijo
