Hemp (Cannabis sativa L.) trials in southern Sweden 1999-2001

Abstract

Results from hemp experiments in European countries indicate that long day conditions may be beneficial for the fibre content and quality of hemp. The long day conditions during summer in Sweden are therefore of particular interest. The paper presents results from the first fibre hemp experiments carried out in Sweden since the 1960s. Field trials were performed in southern Sweden, 1999-2001 testing three monoecious varieties (Felina, Fedora and Futura) at seed rates of 30 and 60 kg/ha. The trials were harvested at the seed ripening stage in the autumn. Total biomass yield in autumn varied from 7.8 to 14.5 ton DM/ha and hemp fibre yield from 1.9 to 3.3 ton DM/ha. The highest fibre yields per hectare were produced by the variety Futura, the lowest by Fedora. The seed rate 30 and 60 kg/ha gave similar biomass and fibre yield, but the plant population and development and the stem diameter were better at 30 kg/ha. Results of chemical analyses of stem and leaves are presented
