FORMING PRODUCTIVITY OF SWITCHGRASS OF THE THIRD VEGETATION YEAR

Abstract

The results of the experiments show that the forming switchgrass phytomass productivity that is raw materials for biofuels production depends on the assortment, weather conditions and elements of growing crop technology. The quantitative indicators of vegetative aboveground mass and productivity of dry phytomass crop in terms of varieties studied on different areas of plant nutrition have been determined. Influence of experimented factors on the productivity elements (height of plant and number of stems per unit area) and productivity of dry phytomass switchgrass varieties Cave-in-Rock, Carthage and Foresburg has been established.
