ENIn Lithuania, yielding potential of the industrial hemp (Cannabis sativa L.) cultivars Beniko, Bialobrzeskie, Epsilon 68, Fedora 17, Felina 32, Futura 75, Santhica 27, USO 31, and Wojko was investigated at the Upyte Experimental Station of LRCAF in 2010-2012. The results show that plants of industrial hemp cultivars tested could be successfully grown in Lithuania, despite the fact that all those cultivars were developed in the countries more southerly than Lithuania. The data of green above-ground biomass yield, its moisture content and absolutely dry mass yield are discussed. Plant density and its reduction during the growing seasons were also evaluated. Keywords: biomass, Cannabis sativa L., plant density, hemp, cultivars.
