Abstract
In a stationary experiment, the size of the removal of nitrogen, phosphorus and potassium from the flax crop and their consumption for the formation of a crop unit during cultivation in the Central region of the Non-Chernozem zone on sod-podzolic light loamy medium-cultivated soil were determined. A significant variation in the chemical composition of flax plants and the removal of NPK by the main products, taking into account by-products, is shown. Potassium removal per 1 ton of fiber was characterized by the lowest variability (coefficient of variation 9.8%). It is shown that the use of different fertilizer systems in crop rotation, in comparison with the non-fertilized version, increased the yield of flax products and increased the total NPK yield. The chemical composition and removal of batteries did not depend on the fertilizer system, but varied depending on the conditions of moisture supply during the growing season. With sufficient moisture, the total removal of nutrients by flax per unit area increased, and decreased in arid conditions. With an average yield of 10.5 c/ha of flax fiber and 5.3 c/ha of flax seeds, nitrogen removal averaged 53.7, phosphorus – 18.2 and potassium – 56.7 kg/ha. When cultivating flax in dry years, there is a tendency to increase the removal of 1 ton of fiber from nutrients: nitrogen – by 18.7, phosphorus – by 0.9, and potassium – by 4.7 kg. Flax varieties dolguntsa A-93 and Lenok, in comparison with the Torzhoksky 4 variety, were distinguished by a higher consumption of nitrogen, phosphorus and potassium for the formation of 1 ton of flax seeds.
