Abstract :In this study, it is evaluated the relationship between in climate and variability in above-ground net primary production insert ignore into journalissuearticles values(ANPP);, above-ground live biomass insert ignore into journalissuearticles values(AGLB); and peak above-ground live biomass insert ignore into journalissuearticles values(PAGLB); in grazed and ungrazed temperate grasslands from northern Turkey. Rain use efficiency insert ignore into journalissuearticles values(RUE); is averagely estimated as 0.51±0.11 and 0.85±0.20 gDM.m-².mm-¹.yr-¹ in grazed and ungrazed stand of the study area respectively. The monthly and annual precipitation indicate to have linear relationship with ANPP and PAGLB according to the regression analysis in ungrazed and grazed stands of study area. RUE of ungrazed stand was generally higher than grazing stand.
