| Abstract | Objective. To determine the productivity formation of oilseed flax using the biological preparation Biophosphorin and different phosphorus fertilizers rates. Methods. Field, measurement, calculation-comparative, analytical, and statistical methods. Results. Studies have shown that phosphate-mobilizing biopreparation Biophosphorin (1 l/t), when pre-sowing treated with flax seeds, increases the number of capsules per plant by 2.57%, and the number of seeds in one capsule by 3%, which leads to an increase in seed yield by 6.6% to 0.95 t/ha. Inoculation, as a measure, is comparable in yield to the application of 18.6 kg of active substance mineral phosphorus. The highest effect was achieved by combining mineral phosphorus with a biological preparation. In the variant P15 + Biophosphorin (1 l/t) the increase of yield was 9.2%, and in the variant P30 + Biophosphorin (1 l/t) the excess reached 10.5%. Conclusions. In the conditions of the Southern Steppe of Ukraine, on southern chernozem soils with an average phosphorus content of 35.24 mg/kg of soil, the oilseed flax variety Vodohrai responds positively to measures aimed at improving phosphorus nutrition. The phosphate-mobilizing preparation Biofosforin (1 l/t) used for pre-sowing seed treatment increases the number of capsules per plant by 2.6% and the number of seeds per capsule by 3.0%, which leads to a 6.6% increase in seed yield, reaching 9.45 t/ha. Inoculation as a measure has an effect on yield comparable to the application of 18.6 kg of mineral phosphorus. The combination of mineral phosphorus fertilizers with the biological preparation Biofosforin provides a more pronounced positive effect on the yield of oilseed flax. The highest yield (9.79 t/ha) was obtained with the combined application of P30 + Biofosforin, which indicates a positive interaction between the biological and mineral components of the technology. The integrated use of various components for optimizing phosphorus nutrition ensures the highest efficiency and is the most effective approach for increasing yield. | ||
