| Abstract | The purpose of the article is to study the influence of pre-sowing seed treatment and optimization of nutrition background on the fat content in oil flax seeds and the conditional oil yield per hectare of the medium-ripening variety Nadiynyy. Methods. Field, laboratory, calculation, statistical analysis. The results. The results showed that improving the agro-nutrition increased the fat content in oil flax seeds by 0.3–1.6 %. Pre-sowing seed treatment with microfertilizer Bast Complex also increased the fat content, although the difference between treatments did not exceed 0.4 %. The maximum oil content was achieved through a combination of pre-sowing seed treatment with microfertilizer Bast Complex, application of mineral fertilizers at the rate of N15P15K15, and foliar feeding with microfertilizer Bast Complex, organo-mineral fertilizer Organic D-2M, or micronutrient Boron, resulting in a 49.0–49.3 % increase in oil yield per hectare compared to the control without fertilizer application and with seed treatment with water. The moisture availability during the growing season significantly influenced the fat content in oil flax seeds, with an evident correlation between the two indicators.: R = 0,7509–0,7423. The correlation-regression dependencies between yield and fat content in oil flax seeds showed a high degree of correlation between the two indicators: R² = 0,8357–0,9237. The maximum conditional oil yield per hectare of oil flax crops was achieved through the N15P15K15 + Bast Complex, N15P15K15 + Organic D-2M, and N15P15K15 + Boron treatments, resulting in 0.70–0.72 t/ha and 0.76–0.79 t/ha yields for seed treatment with water and pre-sowing seed treatment with microfertilizer Bast Complex, respectively. Conclusions. For oil flax cultivation in the Southern Steppe of Ukraine on chernozem soil, it is recommended to use pre-sowing seed treatment with microfertilizer Bast Complex, application of mineral fertilizers at the rate of N15P15K15 during pre-sowing cultivation, and foliar feeding with microfertilizer Bast Complex, organo-mineral fertilizer Organic D-2M, or micronutrient Boron during the tree phase. | ||
