Cultivation area of industrial hemp in Europe has increased since 2012. It is expected
that in future its production will increase, because European Union (EU) policy focuses more on
the ‘green deal’ goals. Research into the effects of climate conditions (temperature and rainfall)
on growth is important to select the best industrial hemp varieties for hemp products. The
objective of the research is identifying industrial hemp varieties suitable for seed, fiber and shives
production in varying pedo-climatic conditions in order to obtain products with the highest added
value.
Four industrial hemp varieties were used for the research: ‘Purini’ (Latvia), ‘Bialobrzeskie’
(Poland), ‘USO -31’ (France-Ukraine), ‘Finola’ (Finland). Field trials were carried out in Eastern
Latvia in 2010, 2011, 2012, 2013, 2019. Climatic indicators were recorded during the vegetation
period from April to September. Yields of seeds, fibre, shives and total biomass were determined
during the research. Factor analysis method was used to determine the impact of temperature and
rainfall on the yield of seeds, fibres and shives. The study of climatic factors shows that the effect
of temperature and rainfall on seed, shives and fiber yields strongly depends on the variety.
