The influence of two-year rest of heavily trampled pastures on bioproductivity of grass associations.
Abstract and Figures
The paper is devoted to the problem of recovery of vegetation and raising the biomass productivity of trampled foothill pastures of Ararat Valley of Armenia. It has been shown that 2-year rest of overgrazed experimental plots as a whole positively impacted on increase of biomass of above- and underground parts on both annual and perennial grass species. It was also established that the extent of influence of this measure was mainly determined by biological peculiarities of species studied. In addition, the biomass yield and energy yield potential per unit area of studied plant associations with predomination of annual and perennial forms increased correspondingly by 1.4-1.9 and 2.4-2.9 times.
