APPLICATION OF NEW CHELATE AGENTS ON OILSEED FLAX
The article presents data on the effect of complex chelating agents Chelaton Extra and Chelate Zn on the oilseed flax variety Severny when grown at the field station of Russian State Agrarian University – Moscow Timiryazev Agricultural Academy. The study found that the agent Chelaton Extra increased the fiber yield better, and the agent Zn Chelate increased the seed yield by 0.7–1 c/ha and 2.4–2.5 c/ha, respectively. The agent Chelate Zn, relative to Chelaton Extra, increased proteins in seeds by 2.9–4%, lipids by 3.6–4.2%. The use of complex chelating agents increased the oil yield and the amount of unsaturated fatty acids. The essential α-linolenic (Omega 3) acid increased in the oil of the variant with Zn Chelate up to 62.2% relative to the control (55.5%). The microstructure of the shell of oil flax seeds in all variants of the experiments was smooth, without disturbances and damages. The seed nucleus has a distinct porous structure; no differences were found in the variants. Chelate Zn more affected the seed productivity and nutritional value of flaxseeds and flaxseed oil, and Helaton Extra more affected fiber yield. The authors found that the Zn Chelate agent influenced seeds’ chemical composition, promoting an increase in potassium, calcium, magnesium, sulfur, and phosphor by 1.5–5%.
