Anotācija With the increase of the demand for recyclable materials the usage of natural fibers in technical textiles goes up. Hemp areas just for fibre production slightly grow up every year. Basically foreign varieties are used. To assess the suitability of these Cannabis Sativa varieties in Latvian climatic conditions fibers obtained from the fields of Agricultural Centre of Latgale were studied. Experiments were started in 2010 with the analyse of fibres from nine varieties: Bialobrzeskie, Beniko, Epsilon 68, Fedora 17, Felina 32, Santhica 27, Futura 75, USO 31, Finola. All varieties are devised for obtaining fibre, except of the variety Finola. The fibres of this variety were studied to compare them with fibers of local variety Purini. Variety Purini not only gives very good amount of seed, but also much larger straw yield than the variety Finola. Therefore the task is to examine if hemp of variety Purini is good for both seed as well as fibre production. The yield and fibre quality of different varieties in the field and laboratory experiments were examined. The thickness, flexibility and tensile properties were determinedto characterize fibre quality. Fibres were obtained from different places of the straws to determine the type of cutting. The best fibres were in the middle part of straws. Therefor it is better to cut hemp in several levels. From the experiments there was drawn a solution that it is better to cut hemp during blooming. Then it is more time for dew retting. There were examined influence of both seed sowing amount and usage of nitrogen amount on fibre quality and straw yield. The work will be continued and the results will be checked in future years.
