Abstract

The aim of this work was to asses the factors influencing the yield and the quality of essential hemp oil. Several strains have been used to carry out field and greenhouse experiments, scent tests and chemical analysis of the distilled oils.
Yields were highest at seeding rates of 5 kg/ha and when about a 50% of the seeds had reached maturity. Prevention of pollination lead to significantly higher yields, but is not easy to perform out on the field. Chemical composition showed almost no relationship to harvest dates or to the scores of the scent tests. The best scent quality was always obtained from plants harvested one to three weeks before seed maturity (75% of matured seeds). The time period during which both yield and quality were high was rather short and has to be assesed for every strain. The influence of other factors like weather and harvest technique were evaluated.
