Application of elements of the information and analytical system of crop management to ensure resource-saving production of flax seeds in the Tver region

Relevance. The concept of precision agriculture call for the use of physical and mathematical, technical and software tools for obtaining and processing information about agroecosystems, as well as for the implementation of agricultural practices directly in the field. To date, there are quite a few software products that can control the production of crops, in particular, the management of differentiated fertilization and compliance with elements of cultivation technology. The purpose of our research conducted over two years was to develop and test in real field conditions algorithms for the functioning of the module of the information and analytical system of crop management for specialized crop rotations involving flax.Methods. The objects of research were the elements of the information and analytical management system for resource-saving production of crop production "Vash urozhaj" (IASUR) and flax-long-lived variety Tonus (selection of the FSBI FNC LC). The experiment used an electronic field map in kml file format containing the coordinates of points, quantitative characteristics of indicators of the content of nutrients and chemical elements in elementary areas within the surveyed spatial object, a technological map of the cultivation of flax, developed specifically for this variety, task maps for the application of solid and liquid fertilizers in .csv file format.Results. Developed and formed in the information and analytical system "Vash urozhaj" electronic technological map of the cultivation of flax-long-legged variety Tonus, containing a list of technological operations, timing and quality characteristics of their implementation, including a possible set of machinery and equipment. The possibility has been tested and the effectiveness of the module for obtaining climatically secured flax yield has been determined — the planned estimated yield for this flax variety at the pilot site is 4.3 c/ha. When cultivated according to the technology adopted in the Federal Scientific Center of Bast Cultures, introduced into the agroplatform, a yield of 4.0 c/ha was obtained. The yield deviation by 6.98% relative to the calculated one is due to the weather features of the growing season of 2021.

Crop yield and water use efficiency in response to long-term diversified crop rotations.

Crop production and water productivity may be impacted by diverse crop rotation and management practices. A field study was conducted from 2017-2020 in the Loess Plateau to evaluate the effects of crop rotation sequences on pre-planting and post-harvest soil water storage (SWS), annualized crop yield, water use, and water productivity. Crops in rotation included oil flax (Linum usitatissimum L.) (F), wheat (Triticum aestivum L.) (W), potato ( Solanum tuberosum L.) (P). Twelve 4-year-cycle crop rotation treatments, along with a continuous oil flax treatment as a baseline, were included. The results showed that the average soil water content under the 0-150 cm soil layer in all treatments was increased after one rotation cycle, and the PWFW treatment achieved the highest SWC (17.1%). The average soil water storage (winter fallow season) and evapotranspiration (ETa) (growing season) under different crop rotation sequences were lower than those under continuous oil flax cropping. The ETa of FFFF increased by 28.9, 2.7, 15.3, and 28.4%, compared to average crop rotations in 2017, 2018, 2019, and 2020, respectively. Crop rotation had a significant effect on average annual yield and water use efficiency (WUE), which varied by year and rotation sequence. The crop rotations with the highest grain yield of oil flax were FFWP (2017), WFWP (2018),WPFF (2019) and FWPF (2020); the grain yield of wheat was highest when the two pre-crops (previously cultivated crops) were F-F, and potato yield was highest when the two pre-crops were W-F (except 2018). On average, the WUE of oil flax was 8.6, 38.7, 22.7, and 42.1% lower with FFFF than other diversity crop rotations in 2017, 2018, 2019, and 2020. We found that the WUE was not the largest when the grain yield of oil flax and wheat was highest. The treatments with maximum grain yield and WUE were not consistent. Our findings also revealed that wheat-potato-oil flax or potato-wheat-oil flax rotation could increase oil flax grain yields while wheat-oil flax-potato-oil flax markedly improved oil flax WUE.

Studying the Innovative Flax Pulling Process in Apparatuses with Transverse Pulling Channels

Introduction. During fiber-flax harvesting, the working tools of pulling units actively interact with the flax plants. The flax pulling unit with transverse tape-disc pulling channels is characterized by the separation of technological plant flows resulting in the loss of seeds and damage to the flax stems. The aim of the work is the theoretical and experimental substantiation of changes in the design of the pulling units with transverse tape-disc pulling channels by eliminating the separation of technological plant flows during flax pulling. Materials and Methods. Experimental studies to substantiate the parameters and modes of the pulling unit operation were carried out according to available and newly developed methodologies, while the evaluation of flax products was carried out according to current GOSTs (Russian National standards). There was determined the influence of the flax ripeness stages, flax yield, and a type of pulling unit on the indicators of separation of technological plant flows and on seed losses. The influence of the pulling unit type, operating width of the pulling section, and the pulling unit speed on the indicators of processing flax straw was also established. Results. There was obtained the dependence for determining the flax stem base elongation, taking into account the seed boll cohesion. The design of the modernized flax pulling unit was used to assess the effect of reducing the flax stem base elongation and eliminating the separation of technological plant flows during pulling on the reduction of seed loss and increase in the yield of flax longs. In the improved flax harvester, the frame elements are positioned behind the pulling unit. Thanks to the modernization of the pulling unit, the flax straw was of higher quality: 1.5 numbers at THLN-1.9M and 1.25 numbers at THLN-1.9P. Discussion and Conclusion. The modernized pulling unit THLN-1,9M during flax harvesting in the stage of early yellow ripeness, compared with the unit THLN-1,9P, can reduce seed loss by 1.4-2.0%, increased output of long fiber by 1.3%. The production of flax longs increases to 0.45 of its number.

Productivity and quality of flax in the application of mineral fertilizers and folk fertilization of plants with the preparation Controlfit

Studies to assess the effect of foliar top dressing of flax with a silicon-containing preparation Controlfit were conducted on different backgrounds of mineral fertilizers in conditions of sod-podzolic medium loamy soil. The experiment was carried out in 2019-2021 on the field of a Separate subdivision of the Smolensk Research Institute of the Federal State Budget Research Institution – Federal Research Center for Bast Fiber Crops. The object of the study was a new variety of flax Phoenix, bred by Smolensk breeders. According to the results of the experiment, it was found that the yield of flax varied greatly over the years of the study, depending on weather conditions. On average, over 3 years of research, the highest yield of flax seeds was obtained on the variant with the maximum dose of mineral fertilizers N48P48K48 and amounted to 6.4 c/ha (83% of the control). Foliar top dressing with Controlfit did not change or even reduced the yield of flax seeds, as it led to the production of lighter seeds and fewer boxes on plants. The combined use of mineral fertilizers increased the yield of flax by 27-66%. The treatment of flax plants with the preparation Controlfit additionally increased the yield of straw by 31%. The effect of mineral fertilizers had a positive effect on the formation of long flax fiber, increasing its yield by 1.2 times relative to the control without fertilizers. Additional treatment of plants with Controlfit increased this indicator by 10-11%. The strength of flax fiber threads increased by 16% with an increase in the dose of mineral fertilizers and by 23% with the use of foliar fertilizing.

Integrated agronomy for high yield and stable flax production in Canada

AbstractIntegrating agronomic practices can be useful in increasing flax (Linum usitatissimum L.) yield under biotic or abiotic constraints. A study was conducted to determine the combined effect of seeding density, row spacing, fertilizer, and fungicide application on no‐till flax yields at three locations (7 site‐years) in Saskatchewan and Manitoba, Canada. The four treatments were plant density; low (190 plants m–2) vs. moderate (320 plants m–2), row spacing; narrow (20 cm) vs. wide‐row (40 cm), N rate; 65 vs. 130% of soil test recommendation, and foliar fungicide; pyraclostrobin + fluxapyroxad vs. no fungicide. No individual treatment parameter significantly affected yield; however, several combinations of treatments did. The combination of moderate density, narrow row spacing, 130% N, and fungicide application showed a 23% mean yield increase across all environments compared with the lowest‐yielding combination. Still, yield ranking differed across different growing environments. The overall high‐yielding combination was not productive under low‐yielding environments. The same high‐yielding combination, but with wide row spacing and the same combination with low density provided the most stable and moderate yield across all environments tested. Considering seed cost, yield advantage, and yield stability, the best combination was low density, narrow row spacing with 130% N and fungicide application. Among all practices, the combined application of 130% N and fungicide application significantly increased crop yield by 11% under all growing conditions. In the absence of negative interactions, producers can combine these four practices to increase flax yields depending on the cost.

Peculiarities of herbicide use on oil flax in different soil and climatic conditions of the Western Ciscaucasia

The article presents the research results on the effect of pre-emergence and foliar herbicide treatments on the oil flax productivity in soil and climatic conditions of unstable and insufficient moistening zones of the Western Ciscaucasia. The pre-emergence application of herbicides Frontier Optima, EC (1.2 l/ha) or Dual Gold, EC (1.6 l/ha) on leached chernozem in the zone of unstable moistening led to an increase in the oil flax yield which exceeds the control with the manual weeding by 0.09 t/ha. The additional foliar treatment of sowings with Tifi, WDG (0.025 kg/ha) decreased the crop yield by 0.29 and 0.23 t/ha, respectively. The highest increase in yield (0.07 t/ha) on leached chernozem in the zone of insufficient moistening was achieved with the pre-emergence application of herbicide Dual Gold, EC (1.6 l/ha).

Оценка продуктивности сортов масличного льна в условиях Свердловской области

Oil flax was grown on gray forest soils of the Sverdlovsk region. The purpose of the research was to compare the yield of new varieties of oil flax, to justify the yield value by elements of the yield structure and to determine the seed quality by biochemical composition. The research method was a field experiment with variance analysis of experimental data. We established that in the Sverdlovsk region, even in extreme meteorological conditions, it is possible to obtain the oil flax yield of 1.8–2.2 t/ha. In the ecological trial, the varieties Uralsky, VNIIMK 620 FN, RFN, Fliz, Rachel and Lirina were distinguished by early maturity, in which the growing season was 82 days, which is 10 days shorter than late-maturing varieties. According to the seed yield in the conditions of 2021, the varieties Lirina (2.04 t/ha), Uralsky (1.88 t/ha), VNIIMK 620 FN (1.71 t/ha), Fliz (1.64 t/ha) and Rachel (1.73 t/ha) were distinguished. With small differences between varieties in plant density, the yield value was determined by the optimal combination of the main elements of its structure – the number of pods per 1 plant, seeds in a pod and the thousand-seed weight. The highest yield in the competitive trial was formed by the variety Uralsky yellow (2.28 t/ha). By thousand-seed weight, it is inferior to the variety Northern (standard with brown seeds), but exceeds the similar variety LM 98 with yellow seeds by 1.32 g. In the warm and arid conditions of 2021, flax seeds were characterized by increased oil content. By this trait, the varieties August (48.6%), RFN (46.9%) and Azurite (46.6%) were distinguished.

Гербициды почвенного действия в системе защиты масличного льна от сорняков на юге России

Since there are no pre-emergence herbicides in “The State Catalogue of pesticides and agrochemicals” approved for use in the Russian Federation on oil flax, in 2018–2020, we studied the pre-emergence herbicides on crop sowings in the zone of unstable moistening on leached chernozem (VNIIMK, Kras-nodar) and in the zone of insufficient moistening on ordinary chernozem (Don experimental station of VNIIMK, Rostov region). We observed the decrease in weed infestation in oil flax sowings when we ap-plied pre-emergence herbicides. The highest biological effectiveness was observed in the zone of unstable moistening, when the plants were sprayed with Tifi, WDG (0.025 kg/ha) at the stage of true leaves development of flax on the background of pre-emergence application with Frontier Optima, EC (1.2 l/ha) – 63.2%; in the zone of insufficient moistening – at pre-emergence application with the tank mixture Dual Gold, EC (1.6 l/ha) + Gezagard, SC (3.5 l/ha) – 67.8%. However, we recorded the phytotoxic effect on oil flax at application of the tank mixture Dual Gold, EC (1.6 l/ha) + Gezagard, SC (3.5 l/ha) in the amount of 23.7–35.7% on the EWRC scale (Europe-an Weed Research Council). We established the positive effect of pre-emergence soil herbicides Frontier Optima, EC (1.2 l/ha) and Dual Gold, EC (1.6 l/ha) on the oil flax seed yield and economic indicators of its production. Herbicides Frontier Optima, EC (1.2 l/ha) and Dual Gold, EC (1.6 l/ha) are recommended for inclusion into the list of preparations approved for use on oil flax in the Russian Federation. Crop foliar treatment with herbicide Tifi, WDG (0.025 kg/ha) on the background of pre-emergence application of the preparation Frontier Optima, EC (1.2 l/ha) or Dual Gold, EC (1.6 l/ha) in the zone of unstable moistening led to yield decrease by 0.29 and 0.23 t/ha, respec-tively, it did not affect the oil flax yield in the zone of insufficient moistening.

Optimization of seed rate and nutrient management levels can reduce lodging damage and improve yield, quality and energetics of subtropical flax

Subtropical flax crop often faces an acute problem of lodging owing to having medium to severe winds coupled with occasional rains during its maturity time. To address this problem an experiment was conducted with three different seed rates and six different nutrient managements for two consecutive years during 2019–20 and 2020–21 at Pantnagar. From this two-year study, it was observed that the higher seed rate of 100 kg ha−1 resulted in the maximum plant population, plant height, fibre yield as well as quality among the different seed rate levels. However, lower stem diameter, higher fresh weight of the stem, centre of gravity and poor tensile performance with higher seed rate exhibited lower values of lodging safety indicators. Considering the different nutrient managements, application of 90 kg ha−1 nitrogen (N), 30 kg ha−1 phosphate (P2O5) and 45 kg ha−1 potassium (K) was found to be the best in terms of reduction of lodging vulnerability with better yield, quality and net energy output of fibre production with saving about 25% of the N input. The seed rate of 100 kg ha−1 when combined with 90 kg ha−1 N, 30 kg ha−1 P2O5 and 45 kg ha−1 K2O resulted in optimum crop performance and the lowest lodging under subtropical humid region. The calculated lodging indicators were found exponentially related with actual lodging. The experiment further reveled that lodging damage directly impacts fibre quality and proportion of long fibre in the total fibre yield.

Урожайность льна масличного и микробиоценоз чернозема обыкновенного при внесении золоуглеродного препарата агробионов

Every year the anthropogenic impact on natural resources on the territory of Kazakhstan, in particular, on the soil cover, is increasing, which leads to its degradation. Along with this, there is a decrease in the content of humus, available forms of nutrients in the soils of the republic, which leads to a sharp decrease in the productivity of crops. In this regard, there is increasing concern for maintaining a stable bioproductivity of the country's soil resources. To solve existing problems, it becomes necessary to take measures on the part of the state to reproduce soil fertility and rational use of soil resources and agricultural land. The accumulation of waste is also a global and national environmental problem. Ash and slag belong to V hazard class waste (practically safe), and they are quite applicable as fertilizers for agriculture and are of great importance for the environment, as they contribute to waste disposal. The article presents the results of examining the doses effect of the preparation from ash and slag and technical fertilizer on the biological activity of ordinary chernozem and the yield of oil flax. The experiments were carried out on the experimental field of the Educational-Scientific-Production Center "Elite" of Sh. Ualikhanov Kokshetau University. The microbiological activity of the soil was determined by the method of application of flax. It has been established that the application of the preparation made from ash and slag and carbon black contributes to the activation of microbiological processes in ordinary chernozem and an increase in the yield of oil flax.

Energy dose of flax seed treatment in a magnetic field

Pre-sowing treatment of flax seeds in a magnetic field makes it possible to improve seed sowing performance and increase flax yield without the use of mineral fertilizers and chemical plant protection products. Compared to other electrophysical methods, pre-sowing seed treatment in a magnetic field is a highly productive, low-energy, safe method for service personnel and the environment. It is now established that the yield and biometric indicators of crops depend on the dose of magnetic treatment. Therefore, the aim of the study was to determine the optimal energy dose of flax seed treatment in a magnetic field. An analytical expression for determining the energy dose of flax seed treatment in a magnetic field is obtained, which contains all the mode parameters of seed treatment. It is established that the energy dose of flax seed treatment in a magnetic field depends in direct proportion to the square of magnetic induction and polar division and inversely proportional to the velocity of seed movement in a magnetic field. The conducted multifactorial experiment made it possible to determine the germination energy and germination of flax seeds at different energy doses of treatment. This made it possible to determine the optimal mode of flax seeds treatment in a magnetic field. It is established that the optimal mode of pre-sowing treatment of flax seeds in a magnetic field is magnetic induction 0.065 T, four-fold re-magnetization, pole division 0.23 m, seed velocity 0.4 m/s, providing an energy treatment dose of 1.79 J · s/kg. With the optimal treatment of flax seeds in a magnetic field, germination energy increased by 30 %, germination - by 2 6%, stem length - by 10.5 %, straw yield - by 0.7 t/ha, seeds - 0.79 t ha.

Control the productivity of flax by treating seeds with microelements and nanopreparation

The purpose of the research was to compare the effectiveness of nanopreparation Nutrivant Plus and trace elements on the growth, development and yield of flax. The experiment was conducted in 2017-2018 on the field of the Smolensk State Agricultural Academy. The object of the study was the flax variety S-108, zoned in the Smolensk region and bred in the Smolensk Research Institute of Agricultural Sciences (former Smolensk State Agricultural Stantion). According to the results of the experiment, it was found that trace elements and nanopreparation increased the germination of flax seeds to 93.6 %. The density of standing plants and their number before harvesting in the variants with the use of trace elements was higher than when using nanopreparation. Treatment of flax seeds with solutions of trace elements to a greater extent contributed to an increase in the yield of flax products. The largest increase in flax straw was obtained from wetting the seed material with iron and zinc sulfate – 3.2 – 4.2 t/ha (53-70 %); for flax fiber – 0.8 – 1.1 t/ha (89 – 122 %). The highest yield for seeds was obtained from treatment with nanopreparation, the increase relative to the control was 0.2 t/ha or 67 %. To achieve high profit and profitability in the cultivation of flax, it is advisable to combine seed treatment before sowing (wetting) with 0.05 % water-dispersed suspension nanopreparation of Co and Fe.

Goal. To study the yield of flax of varieties Rushnychok and Vruchyi at the use of different methods of sowing, seeding rates, and different types and doses of mineral fertilizers in seed crops. Methods. Field experiments were carried out at the experimental sites of the NSC “Institute of Agriculture NAAS”. The research compared two Ukrainian varieties of flax — Rushnychok and Vruchyi. The soil was sod-medium-podzolic dusty-sandy. The following methods were used: field — to determine the interaction of the subject of research with natural and agronomic factors; measuring and weighing — to determine the yield of seeds of flax varieties; statistical, variance — to determine the reliability of the results of experiments. Results. To determine the impact of elements of technology they used indicators of crop structure — the number of boxes on the plant, the weight of 1000 seeds, and seed yield. According to the average data of 2015–2017, intensive flax growing technology at sowing rates of 10 million seeds/ha and application of mineral fertilizers at a dose of N48R48K48 in spring for pre-sowing cultivation, against the background of intensive plant protection provides an increase in seed yield depending on the variety by 15 and 15.8% compared to the control without fertilizers. The best result was obtained for the row method of sowing with a row spacing of 15 cm, for which the yield was 0.69 and 0.66 t/ha in the varieties Rushnychok and Vruchyi, respectively, which was 0.09 t/ha higher than the control variant. Conclusions. As a result of research, it was found that the best method of sowing was a row one with a seeding rate of 10 million seeds/ha and fertilizer application at a dose of N48P48K48, at which the seed yield was 0.69 t/ha for the variety Rushnychok and 0.66 t/ha — for the Vruchyi variety. The developed technology can be used in the cultivation of seed crops of flax and allows to accelerate the reproduction of new varieties.

Effect of Mineral Fertilizers on Productivity and Quality of Winter False Flax

The aim of the research is to study the effect of different backgrounds of mineral nutrition on the yield and quality of oilseeds of winter false flax in different regions of cultivation. The research was conducted in two contrasting regions: the forest-steppe of the Middle Volga region (Penza Research Institute of Agriculture) and the Central steppe zone of Crimea (Crimean Research Institute of Agriculture) in 2018-2020. The object of the research was the winter false flax varietal Baron. In the experiment, the effect of nitrogen fertilizer fertilization on the productivity of winter false flax at a dose of 0 to 60 kg of active substance per hectare with a step of 15 kg has been studied. Ammonium nitrate was used as nitrogen fertilizer. In the experiments of Penza Research Institute of Agriculture, the yield increase with nitrogen fertilizer was 0.07-0.19 t/ha. The highest yield of winter false flax was obtained in the variant with the introduction of nitrogen at a dose of N30, which was 1.61 t/ha, which significantly (0.19 t/ha) exceeded the variant without fertilizers. In the conditions of the Crimea, the yield of winter false flax in the average three years was not high and ranged from 0.95-1.16 t/ha. Fertilizing false flax with nitrogen at a dose of N30 led to an increase in yield by 0.21 t/ha, the productivity of the crop was 1.16 t/ha. Nitrogen fertilizer fertilization led to a slight decrease in the oil content of the seeds. In both regions, the fat content was greatest in the variant without fertilizer and was 39.9 and 40.9 %.

Застосування комплексних мікродобрив та біопрепаратів за органічного виробництва льону олійного

The purpose of research is the development of a competitive, adapted to soil and climatic conditions of the Forest-Steppe zone of the western, organic technology for growing oilseed flax. Research methods – hypothesis, experiment, observation, quantitative-weight, field, visual and comparative calculation. Research results. The use of growth stimulants Vitazim, Ascostart Spectrum for flax seed treatment of flax seeds led to an increase in germination of seeds by 4.2-5.2 % . The highest productivity of seeds oil flax (1.34 t / ha) was obtained by using the biostimulant Vitazim (1.0 l / t) for pre-sowing seed treatment. The increase before control was 14.1 %. Other studies have stimulated the growth and development of plants contributed to an increase in the yield of oilseed flax in the range of 9.5-10.9 %. For complex micro-fertilizers this indicator was in the range of 0.08-0.09 t / ha (6.8-7.8 %). Pre-sowing treatment of flax seeds with growth stimulators Spectrum Ascostart, Vitazim, Ecoline Boron, Vympel 2 influenced the increase of oil content in seeds by 0.5-1.4 %. The highest yield of flaxseed oil for growing flax on an organic basis (0.563 t / ha) was obtained using the biostimulant Vitazim. The increase before control was 0.08-0.095 t / ha (17.1-20.3 %) depending on the method of use. Other complex fertilizers and stimulators of plant growth and development provided an increase in oil yield at the level of 0.048–0.092 t / ha (10.3-19.7 %) with the control indicator at 0.468 t / ha. Analysis of the content of heavy metals in oilseed flax seeds using complex micro-fertilizers and growth stimulants indicates its environmental safety. In particular, their content was significantly lower than the MPC: zinc - 11.4-12.7 (MPC - 50 mg / kg), lead - 0.01-0.07 (MPC - 0.3 mg / kg), cadmium - no more 0.010 (MPC - 0.03 mg / kg), copper - 5.9-6.8 (MPC - 10.0 mg / kg). Conclusions. The use of the studied complex micro-fertilizers and growth stimulants in the organic technology of oil flax cultivation helped to increase the length of the growing season, increased germination and reduced plant disease. The use of these drugs for treatment seed and foliar fertilization led to an increase in seed yield by 9.0-21.8 % compared to control (1.1 t / ha) and an increase in content of 0.6-0.9 % and oil yield in within 0.048-0.095 t / ha (10.3-20.8 %).

Экономическая эффективность возделывания масличных культур в Омской области

We observed the production of oil crops in the Omsk region in 2016–2020. There are presented data on dynamics of sowing areas under oil crops (sunflower, soybean, oil flax, spring rapeseed, false flax, etc.). Production of oil crops is economically profitable due to sharp rise in sale prices of seeds and decrease in prime cost as a result of lowering of expenses for production. A level of profitability during a research period varied hard depending on expenses for chemicals. The most economically resulting was 2020, yields of oil flax and spring rapeseed was the highest. We studied impact of climatic conditions on yield of oil crops, namely precipitation amount in a period flowering–maturing. Increased interest to oil flax, rapeseed and soybean is conditioned with high economic efficiency of production, good adaptability to the climate of the Western Siberia, high yield and oil content, creating of favorable background for the further crops in rotation. Growth of oil crops production in the Omsk region can be reached both by intensive and extensive components of production. Intensive direction is realized by a range of factors including formation of varietal structure of crops, implementation of an intensive technology including all elements of oil crops cultivation. An extensive way proposes expansion of sowing areas involving fallow lands into sowing structure and northward expansion of early maturing crops cultivation, such as spring turnip rape, false flax and mustard.

Formation of oil flax yields when using biological drugs in the Southern Steppe zone of Ukraine

It is noted that flax oil is a promising object in the system of biology of agricultural production, since it has a positive effect on the state of agrophytocoenosis and has a wide nutritional medical and cosmetic application. Production of oilseeds for food and medical purposes should be based on the use of biological preparations of abbrevy, protective and growth of regulatory action. The use of biological preparations on flax crops can improve plant nutrition, provide high-quality protection and contributes to the stability of agrocenoses affected by intensive chemicalization. Modern biological poly functional preparations provide phytohormonal regulation of basic physiological processes in plant organisms and contribute to adaptation to adverse environmental factors such as drought and thermal stress. The purpose of the work is to study the influence of biological preparations on the formation of indicators of oil flax productivity for seed treatment and soliloin feeding of crops during the growing season. The research was carried out on dark chestnut heavy loamy soils in the indigestable crop rotation of the southern Steppe of Ukraine. The object of research is microbiological preparations Ecophosforin, Binok TK, Asphosforin and organic fertilizer Bio-gel, which were used in accordance with the regulations. The experiment used the vera variety, which was grown in compliance with zonal technology. In accordance with the recommendations, biological preparations were used by pre-sowing treatment of seeds on the eve of sowing and spraying plants in the "Christmas tree" phase with a hand sprayer. It has been proved that the use of drugs, improving the nutritional and vital activity of plants, increased the number of boxes and seeds formed by one plant. The use of drugs Ecophosforin and Bio-gel has shown the greatest positive effect on the formation of elements of oil flax productivity compared to control and other options. The average seed weight from one plant was the highest with the double use of organic fertilizer Bio-gel (0.37 g), as well as in the treatment of seeds ecophosforin (0.35 g) and Bio-gel (0.36 g). Treatment of seeds with microbiological preparation Ecophosforin and organic fertilizer Bio-gel increases yield by 0.22 and 0.35 t /ha. Microbiological drug Azotophosforin should be used for processing seeds and crops in the "Christmas tree" phase, which ensures an increase in the yield of oil flax by 0.21 t / ha. The highest yield of seeds was provided by the treatment of seeds with organic fertilizer Bio-gel 0.99 t / ha among microbiological preparations Ecophosforin 0.86 t / ha.
