Consumption of flax for food is growing rapidly due to a high fiber and omega-3 fatty acids content in seeds and high nutritional value. The demand and thus the price are increasing. So, it is reasonable to consider extending the production in our country, too. Field experiment was set up in two different areas of Slovenia (Prekmurje and Savinjska dolina). Presented results are from year 2012. We studied the influence of different pre-sowing tillage (ploughing and without ploughing), nitrogen rate (0, 30, 60, 90 kg/ha N and organic production - EKO /50 kg/ha N/) and time of sowing (beginning of April – S1, the second half of April – S2) on the yield of variety Recital. Yield in Savinjska dolina (1256 kg/ha) was significantly higher than in Prekmurje, where it was similar, regardless of the method of soil preparation (at ploughing treatment 875 kg/ha, at treatment without ploughing 887 kg/ha). With EKO treatment the yield was comparable to the yield of the treatment where similar N rate was applied in the form of mineral fertilizer. There was a negative impact of increasing rates of nitrogen on the flax yield in Savinjska dolina. Yield was higher at S1 compared to S2, where weeds had outgrown flax. In Prekmurje N rate and sowing time did not have significant impact on the yield. There were no problems with diseases and pests, but with weeds.

COBISS.SI-ID: 607372Field experiment with six French flax varieties (Recital, Niagara, Princess, Altess, Comtess and Duchess) was conducted in 2012 on four different locations (two in Prekmurje, two in Savinja Valley, on different soil) as a block trial in four replications. There were no pests or disease detected, the bigger problem represented weeds. Varieties Recital and Princess started to flower earlier compared to the other varieties. High temperatures in July accelerated maturation of all varieties, so that they were mature at the same time. Depending on the location and the variety yield of 927 (variety Princess at location Murska Sobota) to 2288 (variety Altess at the location Savinja Valley 2) kg/ha dry matter was reached. The lowest yield was achieved at the location where soil was light (the year 2012 was rather dry), the largest yield was achieved on the heaviest soil included in our experiment. Weather conditions had a significant impact on yield, too. In Savinja Valley the highest yield achieved varieties Altess and Duchess, while in Prekmurje varieties Comtess and Duchess. On sandy soil in the dry year variety Comtess was indicated as the most suitable, but on heavier soil all the other varieties reached better yield.

COBISS.SI-ID: 619148The contribution of the radio station, which has a relatively large number of listeners all over Slovenia, we acquaint them with flax, the ways of its production, uses and that feeding of domestic animals with its grains influence on higher level of omega3 fatty acids, which are very favorable on human health, in animal products.
