Mineral nutrition of oil flax when using traditional and new organic and mineral fertilizers

Our researches showed an oil flax variety LM 98 is highly responsive on fertilizer application. The increase of seed yield was 15-48%, straw - 24-70%. Application of N45P60K90 allowed obtaining the highest seed yield. The application of new organic and mineral fertilizers based on seaweed for the treatment of flax seeds appeared to be effective. They increased oil flax seeds yield by 25-30% combined with NPK application and by 10-14% compared to the only NPK application, yield of flax straw - 35-40% and 6-13% relative to only NPK. In unfavorable weather conditions, the role of the Sivids increases. Thus, in arid conditions, the increase after joint application of NPK, seed and field treatments by Sivid-Complex was up to 56%, and from mineral fertilizer application only up to 24%.
