In order to determine the yield potential of fibre hemp in
Denmark, defined as seed yield, biomass, stem and fibre production, five
cultivars were evaluated in field trials at two sites during 1998-2000.
The total dry matter yield, stem yield, fibre yield, fibre percent, plant
height, and seed yield were recorded at four seed rates: 8, 16, 32, and 64
kg ha-1 at the Flakkebjerg site. At the Ronhave site, four cultivars were
examined at two row distances: 24 and 48 cm, and one cultivar (Futura)
was examined at four seed rates (as above) in combination with 2 row
distances: 24 and 48 cm. At Flakkebjerg, the total average dry matter
yield of the cultivars Fedora, Fedrina, Felina, and Futura was approximately
13 t ha-1 and for Fasamo approximately 9 t ha-1. The average fibre
yields were 2.9 and 1.7 t ha-1, respectively. At Flakkebjerg, the
average seed yield over a period of 3 years was approximately 500 kg
ha-1. In general, fibre yields increased when seed rates of 16 kg ha-1 or
more were used. At 32 kg seed ha-1 Futura gave higher fibre yields than
at all other seed rates, and higher yields at 24 cm row distance than at 48
cm. Fasamo differed from the other cultivars by having a lower dry matter
yield and a lower percentage of fibre but a higher seed yield.
