Investigation of Hemp (Cannabis sativa L.) Fibre Quantity and Quality as Influenced by Genotype and Seed Rate

Abstract

The investigation on hemp fibre quantity a nd quality as influenced by genotype and seed rate was carried out at the Upyt ė Experimental Station Lithuanian of the Lithuanian Re search Centre for Agriculture and Forestry in 2014. Bi-factorial trial was carried out: Factor A – variet y (A1 – USO 31; A2 – Bialobrzeskie); Factor B – sowing rate (B1 – 45 kg ha -1 ; B2 – 70 kg ha -1 ). Data showed that variety (genotype) had a signifi cant influence on fibre content (after dew- retting as well after water-retting) – it was higher f or variety Bialobrzeskie and amounted to 37.2 and 34 .5%, respectively. Seed rate (or crop density) did not show significan t influence neither on fibre content nor on fibre q uality (flexibility, strength) parameters
