The results of assessing the effect of biological preparations and a seed disinfectant on the technological qualities of grain of soft spring wheat Novosibirskaya 31 are presented. The effectiveness of the use of biological plant protection products was studied in the field experiment, laid down in 2020 in the forest-steppe conditions of the Ob region. Pre-sowing seed treatment included the following options: control (without treatment); Trichodermin, P (Trichoderma viride, titer more than 6 billion spores/g), consumption rate – 15 kg/t seed; Sporobacterin, SP (Bacillus subtilis + Trichoderma viride, strain 4097), consumption rate – 0.5 kg/ton of seeds; Scarlet, ME, chemical standard (imazalil (100 g/l) + tebuconazole (60 g/l), consumption rate – 0.3 l/t of seeds. The use of the preparations contributed to an increase in yield by 0.40 and 0.52 t/ha when using Trichodermin and Sporobacterin, respectively, and by 0.08 t/ha when using fungicide Scarlet. In this case, the mass of 1000 grains increased by 0.84, 0.80 and 0.96 g, respectively, relative to the control. The preparations Trichodermin and Sporobacterin had a significant effect on the growth of grain in length and width relative to the control – by 5.4-6.9 and 9.6%, Scarlet – by 10.6 and 13.9%, respectively. Pre-sowing seed treatment contributed to the growth of such indicators of the caryopsis as volume (by 19.6–29.3%), surface area (by 12.1–19.2%), and sphericity (by 6.3–7.8%). To a greater extent, they increased with the use of fungicide Scarlet. Getting larger grain led to an increase in the endosperm content by 0.76–1.14%. A close correlation has been shown between the indicators of the mass of 1000 grains and the linear grain sizes (r = 0.92–0.98), as well as with the grain volume, sphericity and endosperm content (r = 0.98–0.99). Pre-sowing treatment of spring wheat seeds provides grain with improved technological properties.

Halophytic vegetation is very rare in the forest-steppe zone. It was studied in the tract Serdobsky solonetsin the vicinity of Serdobsk (Serdobsky district, Penza region). The studies were conducted in the years 2009–2018, using the technique of geobotanical profiling. 80 trial areas were laid (35 in 2009 and 45 in 2008). Ecological and phytocenotic classification of plant communities is performed on the dominant principle. Comparison of two descriptions of vegetation with an interval of 10 years allows us to trace the transformation of halophytic vegetation after intensive anthropogenic impact (grazing and partial plowing) in different environmental conditions. The flora of Serdobsky solonets consists of 179 species of vascular plants, of which 13 species are included in the Red book of the Penza region (2013). The share of halophytic vegetation on the territory of Serdobsky solonetshas changed over 10 years: from 97.0 % to 63.8 %. Moreover, halophyte meadows occupied 67.0 % and halophyte steppes 30.0 % of the area in 2009. Now (2018) halophytic steppes make up 30.8 %, and halophytic meadows 33.0 %.The main stages of demutation of halophytic steppe and meadow vegetation were identified in various environmental conditions (meadows and steppes). The same stages of demutation were identified earlier for the South-Eastern Solonets (Neverskinsky district of the Penza region). However, a special stage of annual saline grasslands has been identified.This place requires protection due to the high level of floral and phytocenotic diversity. We offer to organize here a natural monument called “Serdobsky solonets”.

Abstract The studies of the pioneer vegetation of freshwater shorelines of water bodies are of particular interest owing to the specific ecology of these habitats and the short cycle for their development in which periods of flooding and subsequent drainage alternate. Using the methods of phytosociological classification and cluster analysis based on the interpretation of 414 phytosociological relevés, the syntaxonomic structure of the pioneer vegetation of freshwater shorelines of the water bodies of Ukraine has been established that are represented by the phytosociological classes Isoëto-Nanojuncetea and Bidentetea. The class Isoëto-Nanojuncetea includes 8 associations that belong to 2 alliances and 1 order and the class Bidentetea includes 10 associations belonging to 2 alliances and 1 order. Phytocoenoses of both classes are more typical for the Polissia region and the forest-steppe zone of Ukraine, where there are favourable habitats with a flat relief, low degree of dissection and a high level of soil humidity. Using a DCA ordination analysis of associations their position in ecological space was determined. It was established that the main factors of ecological differentiation for Isoëto-Nanojuncetea habitats are soil humidity, soil aeration, nitrogen content, as well as temperature regime. Differentiation in the hyperspace of abiotic factors of the class Bidentetea occurs mainly along the gradients of soil humidity, salt regime and acidity. The ecological distribution of syntaxa of this class is also significantly influenced by the concentration of mineral nitrogen compounds in the soil.

AbstractMorphological variation of vipers of the Vipera berus complex in Eastern Romania, the Republic of Moldova and Western and Central Ukraine was studied using multivariate statistics. Discriminant analysis, based on ten meristic characters in 89.7% of cases (males) and in 92.0% cases (females), was able to separate reference samples of subspecies Vipera berus berus and Vipera berus nikolskii and was conducted to classify snakes from the studied territory. According to these results, V. b. nikolskii inhabits the broad-leaved forests in the forest-steppe zone in the Republic of Moldova, the hilly part of Eastern Romania and Central Ukraine. Specimens from a contact zone between V. b. berus and V. b. nikolskii have intermediate morphology and, thus, could represent the result of introgression. Populations of the Nikolsky's viper from the western part of its range combine high level of morphological differentiation from V. b. berus with the presence of non-black specimens and even include populations without melanistic specimens, previously thought not to occur in this taxon. A morphological description of the largest samples is given and determination of V. b. nikolskii is discussed.

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 %).

Positive Effect

The effect of fertilizers application by the method of fertigation with drip irrigation during seabuckthorn growing in the nursery was estimated. The research has been carried out in the nursery field, in the forest-steppe zone of Altai Krai in 2019-2020. The soil on the experimental plot is gray-forest, reaction of the medium pH 5.8-5.9. The content of nitrate nitrogen was in the range of 7.8-9.8 mg/kg in the control variant; after fertilization, these values rose to 87.9 mg/kg. Nitrate nitrogen was determined by the ion-selective method. The soil at a high level is provided with mobile phosphorus 342-453 mg/kg and potassium 181-355 mg/kg - determined according to Chirikov. The research object – is one-year-old seabuckthorn trees of Altaiskaya cultivar. Urea was applied as nitrogen fertilizer in three rates of the active ingredient (40, 60, and 80 kg/ha). Double superphosphate (30 kg/ha) and potassium chloride (30 kg/ha) were used as the background. The soil moisture level was maintained at 70-80% of the LWC. The effectiveness of fertilizers was assessed by the marketable yield of two-year-old seedlings and their quality indicators. The measurements were carried out in the fall, after excavation. According to the values of the parameters of the aboveground part, the dose of nitrogen fertilizer of 60 kg/ha turned out to be the best option. At the same time, the seedlings had a height of 89.5 cm, the number of branches was 4.4 pcs., The diameter of the trunk was 8.4 cm, which is 15.4 cm, 0.5 pcs. and 1.3 mm above the control. The yield of seedlings of the first commercial grade in the experiment averaged 164 pieces. (82.8%), the maximum is marked on the N60P30K30 variant 190 pcs. (93.8%). Control without the use of fertilizers in all respects is significantly inferior to options with fertilizers. Thus, the use of nitrogen fertilizers has a positive effect on the quality of the seabuckthorn planting material. As a result, the utilization of nitrogen fertilizers has a positive effect on the quality of the seabuckthorn plant material, while higher concentrations become unprofitable compared to low ones due to high costs and insignificant differences in the quality of trees

Abstract The development and application of new reforestation technologies remain relevant due to climate change. The main technology of forest sowing in Russia does not provide effective reforestation. Innovative technologies of reforestation based on seedlings with a closed root system make it possible to increase the livelihood of plants and accelerate reforestation processes. Using the method of determining costs, a comparative economic analysis of the technologies for growing oak seedlings with an open and closed root system in the forest-steppe regions of Russia was carried out. It was found that the technology of growing seedlings with a closed root system is less labor-consuming and provides a high level of income for investments. The innovative technology of growing seedlings with a closed root system in greenhouses is more competitive and its use allows to generate income from one hectare of area 50 times more than when growing seedlings in forest nurseries by increasing the number of seedling rotation. A comparative economic assessment of two oak seedling projects under forest-steppe conditions suggests the feasibility of moving to innovative reforestation technologies. In the current climate change conditions, a serious correction of approaches to reforestation in the forest-steppe zones of Russia is necessary.

Наведені основні результати дослідження, проведеного в північній частині Правобережного Лісостепу України протягом 2014–2016 рр. на чорноземі типовому. Встановлено, що сортові особливості культури, передпосівна обробка насіння «Ризогуміном» та удобрення мали позитивний вплив на формування кількості і маси бульбочок у рослин гороху. Найбільш сприятливі умови для формування симбіотичного апарату створюються за поєднання посівної інокуляції насіння із внесенням мінеральних добрив у варіанті К1+N10P10 BBCH13-19 + N10P10 BBCH55-59+ N10P10 BBCH61-65. На фоні внесення мінеральних добрив N30P90K90 посилюється формування та продуктивність симбіотичного апарату рослин гороху. Вказаний рівень мінерального живлення є ефективним і за сівби насінням, яке не підлягало інокуляції. Внесення високих рівнів мінерального азоту негативно впливає на симбіотичний зв'язок між рослинами гороху і бульбочковими бактеріями. The basic results of research conducted in the northern part of Right-Bank of Forest-Steppe zone of Ukraine for 2014–2016 years on typical black earth are presented. We established that the varietal characteristics of culture, preplant treatment of seeds and fertilizer had a positive impact on the formation of the quantity and mass of nodules in pea plants. The most favorable conditions for the formation of symbiotic system are created by the combination of sowing seed inoculation with fertilizer in version K1 + +N10P10 BBCH13-19 + N10P10 BBCH55-59 + N10P10 BBCH61-65. Against the background of mineral fertilizers N30P90K90 the formation and performance of the device symbiotic pea plants amplified. The indicated level of mineral nutrition is effective and for the sowing seeds that are not subject to inoculation. The high level of mineral nitrogen negatively affects on the symbiotic relation between pea plants and nodule bacteria.
