The productivity of switchgrass variety of fifth year of vegetation, depending on the biometric plants’ indicators

Abstract

The investigated variability of biometric (quantitative) indicators of switchgrass by variety of different groups ripeness. We determined the level of the yield of aboveground vegetative mass culture, installed correlations between quantitative indicators of plants and yield of dry biomass of switchgrass of fifth year of vegetation. It was established that the yield of dry switchgrass phytomass is determined by studied dry matter of content in the phytomass, the number of stems, flag leaf’s length and moisture content in plants.
