Analysis of numerous data shows a great amplitude of productivity variations in overground phytomass of grass communities at a diverse syntaxonomic level. Grass stands of synaathropic (class Artemisietea vulgaris - to 203,0 c/ha in subass. Heracleetum sosnowskyi typicum) and swamp meadow communities (class Phragmitetea - to 187,3 c/ha in subass. Phalaridetum arundinaceae scolochloetosum festucaceae) are the most productive ones. The lowest productivity of overground phytomass is observed in rough meadow communities (class Sedo-Scleranthetea - to 0,6 c/ha in subass. Corynephoretum canescentis hieracietosum pilosellae). From the whole complex of extremal factors edaphotope character and anthropogenic effects are determinant ones in the productivity of communities
