The effect of different rates of fertilizer nitrogen on the yield of fiber flax straw and on utilization of nitrogen by plants was investigated by labelled atoms - 15N - technique. Dependence of straw yield on total removal of nitrogen has been confirmed. After application of nitrogenous fertilizers (30-60 kg of nitrogen per 1 ha) the yield of fiber flax got 1.4-1.9 times higher, and the quality of product was improved. With higher rate of fertilizer the coefficient of nitrogen utilization became lower.
