We studied the fiber flax varieties bred in the Tomsk region in 2017–2019 in the subtaiga zone of the Omsk region on the experimental field of the Northern Agriculture Department of the Omsk Agricultural Scientific Center. We provide the material for 7 varieties. The soil of the experimental plot is gray wooded podzolic, medium, loamy with a humus content of 3–4 %. The predecessor is spring wheat after fallow. The research results showed that the weather conditions significantly affected the growth, development, and formation of the yield. In 2017, cold and wet weather generally affected the yield and quality of fiber flax in comparison to 2018-2019. As a result of the research, we established that for 3 years the best varieties were TOST 5 and Tomich. The variety TOST 5 gave a straw yield of 4.70 t/ha with number 1.9, an estimated fiber yield of 1.31 t/ha and a seed yield of 0.80 t/ha with the growth season of 61 days. The variety Tomich was characterized by the high quality of straw with number 2.1 with a short growth season (48 days), it had a straw yield of 4.0t/ha, a fiber yield of 1.18 t/ha and a seed yield of 0.70 t/ha. Therefore, the combination of varieties of different ripening duration will optimize the harvesting timing, raise the flax straw, and get a high yield of quality products.

Studies on the evaluation of 20 fiber flax accessions of Russian, Chinese, Japanese and Polish breeding from the collection of the Federal Research Center "All-Russian Institute of Plant Genetic Resources named after N. I. Vavilov" (VIR) were conducted in 2018-2020 in order to identify the sources of agronomic valuable characters that are adaptive to the conditions of the North-West of the Russian Federation. The HTC for the growing season in 2018 was 0.95, in 2019 – 1.53 and in 2020-1.1. Abiotic conditions had a greater influence on the formation of plant height (59.6 %), seed yield (60 %) and fiber content in plants (55.1 %), but the influence of the genotype on these indicators was also significant. The effect size of the genotype prevailed in the formation of fiber yield (67.2 %) and the duration of the growing season (52.8 %). The variability of characters was the greatest according to the seed yield (V = 6.7-33.9 %), disease resistance (V = 3.1-26.5 %); the lowest one was noted according to the duration of the growing season (V = 4.4-9.7 %). For the rest characters, it was at the level of up to 20 %. A valuable and plastic source material was identified for practical breeding aimed at creating new varieties with the following characters: early maturity – K-8680 (Russia), K-8782, K-8783 (Japan), which matured 3 days earlier than the Dobrynya standard and had a growing period of 67 days; productivity – K-8651, K-8760, K-8795, K-8797, K-8874, K-8877 (China), which significantly exceeded the fiber yield of the Dobrynya variety (241 g/m2) by 8-14 %. There were identified genotypes significantly exceeding the standard: according to the plant height (82 cm) ‒ K-8681 (Russia), K-8751, K-8794, K-8795, K-8754 (China) ‒ by 12-25 %; yield of flax straw (241 g/m2) – K-8681 (Russia), K-8751, K-8794, K-8795, K-8874, K-8880 (China) – by 25-40 %; seed yield (149 g/m2) ‒ K-8680 (Russia), K-8772 (Poland), K-8782 (Japan) – by 10-23 %; resistance to lodging (9 samples) and diseases (7 samples). Use of the identified gene sources in breeding practice should accelerate the creation of varieties that provide high and stable yields.

Linseed is an important industrial crop cultivated for its edible seeds and fiber linen. Organic fertilizers have beneficial effects on soil properties and quality of crops. Therefore, we conducted two field experiments during 2018–2019 and 2019–2020 to determine the effect of organic fertilizers on soil fertility, yield and fiber quality of linseed varieties Roshni, BL1 and Chandni under low soil moisture conditions. We prepared organic fertilizers from seed cake of Eruca sativa, leaves of Moringa oleifera and chicken peat in various combinations by composting method. The various formulations of organic fertilizers included OF1(1 kg seed cake of Eruca sativa), OF2 (1 kg seed cake of Eruca sativa + 1 kg chicken peat), OF3 (1 kg seed cake of Eruca sativa + 0.5 kg chicken peat + 0.25 kg Moringa oliefera leaves) and OF4 (1 kg seed cake of Eruca sativa + 0.250 kg chicken peat + 0.5 kg Moringa oliefera leaves). Compositional analysis of organic fertilizers indicated that OF3 and OF4 had higher and may potentially sufficient quantities of NPK and organic matter. Both of these fertilizers significantly improved soil total N, available P, K, Zn and Fe contents. Growth response of linseed varieties to organic fertilizers was evaluated under water deficit stress (40% field capacity of soil) at tillering stage for one month. Water stress had significantly adverse effects on plant height, production of tillers per plant, leaf relative water content (LRWC), number of capsules per plant, thousand seed weight, total seed yield, straw yield, fiber length and fiber weight of linseed varieties. However, the application of OF3 and OF4 significantly enhanced plant height, tillers production, LRWC, seed yield, straw yield, fiber length and fiber weight under water deficit stress. Water deficit stress also resulted in a significant increase in the content of phenolics of both the leaves and roots. For each measured quality parameter of linseed varieties, organic fertilizer treatments resulted in higher values than untreated and irrigated control. We concluded that organic fertilizers particularly OF3 and OF4 significantly improved soil fertility and minimized negative effect of water deficit stress on plant height, tillers production, LRWC, seed yield, straw yield, fiber length and fiber weight of linseed varieties.

Особая роль в повышении урожайности и качества льна-долгунца отводится оптимизации питания растений, направленного на совместное применение макро- и микроудобрений. Исследования проводились в 20162018 гг. в Костромской области. Опыты закладывали на дерново-подзолистой среднесуглинистой почве с низкой обеспеченностью элементами питания (кроме фосфора) и оптимальным для льна показателем рН. Агрохимическая характеристика пахотного горизонта: содержание гумуса 1,41,83 (по Тюрину) содержание подвижного фосфора 120176 мг/кг, калия 4498 мг/кг почвы (по Кирсанову), рНkcl 5,065,98 ед. Применяемая в опыте агротехника общепринятая для региона. Опыт был заложен в трёх повторениях. В проведённых исследованиях была изучена возможность увеличения урожайности льнопродукции и улучшения показателей качества волокна за счёт применения внекорневой подкормки растений микроудобрением Аквадон-Микро (2 л/га) в разные фазы развития в фазу ёлочка и в фазу быстрого роста. Применение микроэлементного удобрения Аквадон-Микро по фону минеральных удобрений способствовало увеличению урожайности соломки (на 5,07,3), семян (на 4,56,0), выхода длинного волокна (на 0,21,1), его урожайности (на 6,012,1), номера тресты (на 0,25) по сравнению с контролем. Результаты полученных данных дают основание сделать вывод, что обработка вегетирующих растений микроудобрением Аквадон-Микро приводит к увеличению урожайности и качеству льнопродукции. Опрыскивание им льна-долгунца в фазу ёлочка повышает эффективность данного приёма в большей степени, чем его применение в фазу быстрого роста.A special role in increasing the crop yield and quality of fiber flax (Linum usitatissimum) is played by the optimization of plant nutrition focused on the combined use of macro- and micronutrients. The researches were conducted in 20162018 in the Kostroma region. The experiments were carried out on soddy podzolic middle loamy soil with a low supply of nutrients (except phosphorus) and an optimal pH value for flax. Agrochemical characteristics of the plough-layer: humus content is 1.41.83 (according to Tyurin) the content of labile phosphorusis 120176 mg/kg, potassium is 4498 mg/kg of soil (according to Kirsanov), pHkcl 5.065.98. The agrotechnics used in the experiment is generally accepted for the region. The experience was carried out in three repetitions. In the conducted researches the possibility of increasing the crop yield of flax products and improving the fiber quality indicators due to the application of foliage application of plants with micronutrient Aquadon-Micro (2 l/ha) in different development phases in the herringbone phase and in the phase of rapid growth was studied. The use of the micronutrient fertilizer Aquadon-Micro against the background of mineral fertilizers contributed to an increase in the crop yield of straw (by 5.07.3), seeds (by 4.56.0) and the long fiber yield (by 0.2 1.1), its crop yield (by 6.012.1), retted stalks numbers (by 0.25) compared with the control. The results of the obtained data allow us to conclude that the processing of vegetative plants with micronutrient Aquadon-Micro leads to an increase in crop yield and the quality of flax products. Spraying fiber flax (Linum usitatissimum) with it in the herringbone phase increases the effectiveness of this technique to a greater extent than its use in the rapid growth phase.

Methodology: Two field experiments were conducted on the Experimental Farm at El-Gemmeiza Research Station, Gharbia Governorate, Agricultural Research Center, Egypt, during two successive winter seasons of 2018-19 and 2019-20. Aims: To investigate the effect of three nitrogen fertilizer rates, i.e. 30, 50 and 70 kg N feddan-1 [one feddan (fed) = 4200 m2] and three plant densities, i.e. 1500, 2000 and 2500 seeds m-2 on flax (Linum usitatissimum L.) yield and its quality of three cultivars of flax, i.e. Sakha 3, Giza 11 and Giza 12. Results: Results in combined analysis of the two seasons showed that Sakha 3 cultivar significantly produced the maximum total plant height, technical stem length, upper branching zone length, No. of seeds capsule-1, total fiber percentage, fiber yield plant-1, fiber yield fed-1, fiber length and fiber fineness. Meanwhile, the highest No. of basal branches plant-1, straw yield plant-1, straw yield fed-1 and seed oil content were recorded with Giza 12 cultivar. While, Giza 11 cultivar gave the maximum stem diameter, No. of upper branches plant-1, No. of capsules plant-1, No. of seeds plant-1, seed index, seed yield plant-1, seed yield fed-1, harvest index, oil yield plant-1 and oil yield fed-1. Increasing nitrogen fertilizer rates from 30 up to 70 kg N fed-1 caused significant increases in almost straw, fiber, seed and oil yields and its related traits of flax, on the other hand, fiber fineness which significantly decreased with increasing nitrogen rates. Flax plants growing at 1500 seeds m-2 markedly gave the greatest No. of basal branches plant-1, stem diameter, straw yield plant-1, upper branching zone length, No. of upper branches plant-1, No. of capsules plant-1, No. of seeds plant-1, seed yield plant-1, harvest index, oil yield plant-1 and fiber yield plant-1. Meanwhile, the maximum total plant height, technical stem length, straw yield fed-1, seed yield fed-1, oil yield fed-1, total fiber percentage, fiber yield fed-1, fiber length and fiber fineness were obtained from flax planting at 2500 seeds m-2. The maximum fiber yield were recorded from the interactions among treatments Sakha 3 X 70 kg N fed-1, Sakha 3 X 2500 seeds m-2, 70 kg N fed-1 X 2500 seeds m-2 and Sakha 3 X 70 kg N fed-1 X 2500 seeds m-2. Meanwhile, the maximum seed and oil yields fed-1 were recorded from the interactions between treatments Giza 11 X 70 kg N fed-1, Giza 11 X 2500 seeds m-2, 70 kg N fed-1 X 2500 seeds m-2 and Giza 11 X 70 kg N fed-1 X 2500 seeds m-2. Generally, it could be concluded that Sakha 3 cultivar under soil fertilized by 70 kg N fed-1 with plant density of 2500 seeds m-2 to maximizing fiber yield fed-1, while Giza 11 cultivar with the same rates of nitrogen and plant density to maximizing seed and oil yields fed-1.

Научные исследования выполнены в 2017–2019 годах на опытном поле ФГБНУ «ФАНЦ Северо-Востока». Почва опытного участка дерново-подзолистая, среднесуглинистая, сильнокислая, с содержанием в пахотном слое 1,9% гумуса, средним — подвижного фосфора и обменного калия, подвижного алюминия — от 4,23 до 5,24 мг/кг почвы. В статье изложены результаты исследования влияния минеральных удобрений, в том числе фосфоритной муки, а также известкования на продуктивность и качество кормовой массы лядвенце-тимофеечной травосмеси. Цель работы — определить наиболее эффективные виды минеральных удобрений, в том числе на известкованном фоне, для получения высокой продуктивности и качества кормовой массы. Установлено, что высокая продуктивность лядвенце-тимофеечной травосмеси получена при совместном внесении минеральных удобрений и извести. Сбор сухого вещества составлял более 5,0 т/га, что достоверно выше контрольного варианта в среднем за 3 года жизни трав на 39,9% при внесении фосфорно-калийных удобрений и на 43,8% — при добавлении азотных. Выход обменной энергии в этих вариантах превышал 50 ГДж/га, сбор сырого протеина был более 0,60 т/га. Известкование достоверно увеличивало сбор сухого вещества трав на 19,0%. Фосфоритование не обеспечивало достоверной прибавки сбора сухого вещества. Внесение азотных удобрений (N30) совместно с фосфорно-калийными, как и калийных (К60) с фосфоритной мукой, не приводило к достоверному росту сбора сухого вещества. Содержание сырого протеина зависело от доли лядвенца в урожае. При высоком преобладании лядвенца во втором укосе во второй и третий годы жизни трав содержание сырого протеина превышало 17%. The investigation took place in 2017–2019. Soil — sod-podzolic with medium clay content, low pH, and medium concentrations of soluble phosphorus and exchange potassium. Humus content — 1.9%, soluble aluminium — 4.23 –5.24 mg/kg. The article focuses on the effect of mineral fertilizers and liming on productivity and forage quality of birdʼs-foot trefoil mixed with common timothy. The experiment aimed at identification of the most effective mineral fertilizers leading to high yield and quality of forage mass. Fertilization resulted in high yield of the mixture on the background of liming. Dry matter yield (DM) reached 5.0 t ha-1, significantly exceeding the control by 39.9% under PK fertilization and by 43.8% — when applying NPK. Exchange energy yield exceeded 50 GJ ha-1, crude protein — 0.60 t ha-1. Liming significantly increased DM content by 19.0%. Phosphorite meal had insignificant effect on DM increase. Application of nitrogen fertilizers (N30) in combination with PK as well as К60 with phosphorite meal showed no significant influence. Accumulation of crude protein depended on birdʼs-foot trefoil ratio in the yield. Crude protein exceeded 17% in the second cut due to the high proportion of birdʼs-foot trefoil in the second and third life cycles.

Comparative data on the quantity (yield) and quality (number) of long fiber obtained from flax of fiber flax varieties of foreign and domestic origin are presented during control developments using traditional technology at flax processing enterprises of the Russian Federation. A rating assessment of varieties according to these characteristics for flax trees of low (numbers 0.50–0.75) and higher quality (numbers 1.00 and higher) was carried out according to the existing gradation of division of flax trees into two qualitative groups. It was found that varieties of domestic origin, both in terms of long fiber yield (average index 14.6) and number (average index 15.6) from low-quality flax stands, are inferior to foreign varieties with average indexes of 12.2 and 11.8, respectively. Long fiber obtained from high-quality flax straw of domestic varieties is characterized by a high yield (average index 13.9) and better quality (average index 14.6). For foreign varieties, the average index is: for long fiber yield - 18.0, for number - 16.0. In order to determine the extent to which the potentialities inherent in the varieties in terms of the yield of long fiber are realized in production practice, a comparative analysis was carried out. The results are revealed by means of state test data and the results of control developments. An extremely low degree of implementation was noted. For the best varieties it is slightly more than 50%. A large yield of long fiber under production conditions was obtained from highquality flax trees of domestic breeding varieties, such as Alfa, Aleksim, Lenok, Tost, Sursky and Alexandrite.

Selection Of

The results of scientific research are presented, which made it possible to develop less labor-intensive methods for selecting flax plants to grow original (updated) seeds. Studies have shown that a positive selection of tall plants of flax, compared with the accepted counterpart (control), increased seed yield 1.7-1.9 times. Moreover, plant homogeneity according to the main characteristics (height and fiber content in the stem) characterizing the varietal quality of grown seeds turned out to be at the control level. A negative selection, involving the removal of atypical plants, provided an increase in the output volume of seeds compared to the control by 3.9-4.1 times. This selection method did not reduce the varietal quality of seed material compared to the accepted analogue. With both selection methods, after combining typical plants, seeds with the same high germination rates were obtained (96-99 %). The breeding efficiency of the grown flax seeds using narrow-row sowing methods is shown. Studies have established that narrow-row sowing of seeds with a row-spacing of 7.5 and 6.25 cm compared with sowing by a wide-row method significantly increased their yield by 2.8-3.0 and 2.3-3.0 kg / ha, respectively. The greatest influence on the formation of seed yield in narrow-row sowing (6.25 cm) was exerted by the method of sowing, the part of which was 76.1 %. As the length of seed propagation of flax in creased (up to the uterine elite 2 years) in narrow-row sowing (6.25 cm) compared to broad-row, there was no decrease in quality indicators - germination and seed strength.
