Industrial Hemp Variety Performance in Latvia Under Baltic Sea Climate
“Conclusions
Evaluating the cultivation potential of fiber and seed hemp varieties in the Baltic Sea climate, it can be concluded that the most suitable variety for obtaining high seed and oil yield is ‘Henola’, which showed a 3.5 t ha−1 seed yield and 1.3 t ha−1 oil yield, exceeding the results of other hemp seed varieties by 1.5–2.1 times.
‘Futura 75’, with a fiber yield of 10.8 t ha−1, was the most productive variety for obtaining fibers.
Evaluating both fiber and oil yield, ‘USO-31’, which showed the highest seed yield (1.3 t ha−1) among fiber hemp varieties, as well as ‘KA-2-2011’, which showed the third highest seed yield (2.2 t ha−1) and the highest fiber yield (3.4 t ha−1) of the seed hemp varieties, can be recommended as the most suitable varieties for dual-purpose cultivation in the Baltic Sea climate.
The ‘Bialobrzeskie’ variety demonstrated the highest biomass yield, making it a candidate for cultivation as a renewable energy source or to enhance CO2 uptake.
The viability of hemp shives as a fuel source is evident, given their similar calorific value to wood fuel. It is recommended to incorporate 1–3% calcium hydroxide or calcium carbonate into the hemp shives mixture to elevate the ash melting point of hemp shive-based fuel.”
