Evaluation of Cannabis sativa cultivars in Lithuania
Journal Title: ŽEMDIRBYSTĖ-AGRICULTURE - Year 2010, Vol 97, Issue 3
Abstract
The demand for renewable raw materials is increasing, and many new products processed from strong fibres such as hemp and flax appear all over the world. The industrial hemp (Cannabis sativa L.) is currently not grown in Lithuania. The possibilities of acclimatization of this plant in Lithuania, yielding potential, biometrical indices of five hemp cultivars (‘Beniko’, ‘Bialobrezskie’, ‘Epsilon 68’, ‘Felina 32’ and USO 31) were investigated at the Upytė Research Station of LIA in 2008–2009. The data from 2008–2009 evidenced 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. In 2008, the growing season of hemp cultivar USO 31 was 16 weeks (115 days) and 20 weeks (140 days) for the rest of the cultivars, and in 2009 the growing season of USO 31 was 19 weeks (133 days) and 22 weeks (154 days) for the rest of the cultivars. All cultivars tested were productive, but the highest amount of green over-ground biomass and dry biomass was produced by the plants of the cultivars ‘Epsilon 68’ and USO 31 (respectively, 36.8–47.7 and 36.2–46.0 t ha-1 of green biomass and, respectively, 19.0–22.7 and 16.2–22.6 t ha-1 of absolutely dry hemp biomass. The highest hemp plants were those of the cultivars ‘Beniko’ and ‘Epsilon 68’ (respectively, 2.45 and 2.42 m in 2008), and in 2009 the plants of cultivar ‘Beniko’ were as tall as 2.78 m. Plants of ‘Beniko’ had significantly higher technical stalk length (2.22 m), higher diameter (0.65 m) in 2008. Crop density and its reduction during the growing season were also evaluated.
