Full textAbstract:
The agrotechnical significance of leguminous crops, in particular soybeans, consists in its ability to provide a huge bulk of vegetable protein and less nitrogen depletion of soils than non-legume crops [2]. Despite the fact that nitrogen symbiotically fixed by soybean plants is alienated with the harvest and taken out of the field with organic residues of leguminous crops, more nitrogen remains in the soil after them than with residues of other crops. In this regard soybeans are good predecessors in various stages of crop rotation. The article discusses topical issues of increasing productivity of leguminous crops, in particular, soybeans, when using different doses of ammophos against the background of its placement in various ways of main tillage of drained leached chernozems. In 2018–2019 studies were carried out to establish the influence of the optimal dose of mineral nutrition and the best method of soil cultivation on the productivity and quality indicators of soybeans of the French selection of the Amphora, Mentor and Isidor varieties. According to the results of the research, different effectiveness of the considered variants of the experiment was established. Thus, higher rates of soybean yield were noted in the later-maturing Isidor variety within 2,03–2,30 t/ha for plowing, and 1,70–1,91 for soil disking. The most cost-effective dose of mineral nutrition for all studied soybean varieties was the dose of 50 kg/ha of Ammophos (N6H26) against the background of plowing, where the profit from the increase in yield relative to the control was in the range of 2900–3650 rubles/ha, and against the background of disking soil the dose of Ammophos was 100 kg/ha (N12H52), where the profit was in the range of 1300–2050 rubles/ha.

The current study has been carried out to determine the effect of mineral and organic mineral fertilizers, as well as a growth regulator on the productivity of promising winter durum wheat varieties, under irrigation conditions of meadow-chestnut heavy loamy soil in the Terek-Sulak subprovince of the Republic of Dagestan. In 2019–2021 there were laid on two trials on the experimental plot. In the first case, there were studied four variants of the effect of fertilizers on the productivity of promising varieties ‘Krupinka’ (control), ‘Krucha’, ‘Odari’ under irrigation conditions. There was used ammophos (background), 65 kg/ha a.i. under plowing; ammophos (background), 65 kg/ha a.i. for plowing + Polydon bio universal, 0.5 l/ha in the tillering phase + Polydon bio universal, 0.5 l/ha in the earing phase; ammophos (background), 65 kg/ha a.i. under arable land + ammonium nitrate 150 kg/ha in spring tillering + Polydon bio universal 0.5 l/ha in the tillering phase + Polydon bio universal 0.5 l/ha in the earing phase; ammophos (background), 65kg/ha a.i. for plowing + ammonium nitrate 150 kg/ha in spring tillering. In the second, three winter durum wheat varieties were treated before sowing with 0.5 l/t of Sprintalga and foliar top dressing was carried out in the spring tillering phase, in comparison with the control when seeds were treated with 10 l/t of the working liquid disinfectant Maxim KS. The conducted study has shown that the largest productivity of the studied winter durum wheat varieties was achieved in the third variant of the trial, where grain productivity of 8.36 t/ha was achieved for the variety ‘Odari’, the variety ‘Krucha’ was in second place with 7.91 t/ha of productivity, which was on 0.27 t/ha more than for the control variety ‘Krupinka’ and on 0.45 t/ha less than in the variety ‘Odari’. The use of a growth regulator has shown its significant effect on the grain productivity improvement. Seed treatment of winter durum wheat varieties and crops in the tillering phase with Sprintalgi had a positive effect on the growth, development, and improvement of grain yield. On average, over the years of research, the largest grain yield of 7.88 t / ha was obtained for the variety ‘Odari’, in the variant of seed and crop treatment with a growth regulator Sprintalgi. The productivity difference in the variant with seed treatment with Sprintalgi and with the working liquid treater Maxim KS was 0.67 t/ha for the variety ‘Odari’, 0.71 t/ha for ‘Krucha’ and 0.79 t/ha for ‘Krupinka’.

Установлено, что локальное внесение ЖКУ 11:37 в сравнении со сплошным его распределением в почве достоверно повышает клубнеобразование до 7,1 шт/куст, а внесение аммофоса локально показывает положительное влияние на образование клубней. Использование аммофоса сплошным или локальным способом приводит к образованию более крупных клубней. Максимальную урожайность картофеля 33,2 т/га обеспечивает локальное внесение жидкого комплексного азотно-фосфорного удобрения по фону полного минерального удобрения – N50Р50K250 + N15Р53. It was found that the local application of liquid complex fertilizer 11:37 in comparison with its continuous distribution in the soil signifi- cantly increases tuber formation to 7.1 tubers/plant, and the application of ammophos locally shows a tendency of a positive effect on tu- ber formation. The use of ammophos in a continuous or local way results in the formation of larger tubers. The maximum yield of potatoes of 33.2 t/ha is provided by the local application of liquid complex nitrogen-phosphorus fertilizer against the background of full mineral fertilizer – N50P50K250 + N15P53.

Increasing the yield of pea grain in agricultural production is an important task for modern agriculture in the Orenburg region. To expand it, long-term studies on the influence of weeds and ammophos on the yield of pea grain were carried out. The article presents the research results for 2002-2019 by weediness of crops, the content of macronutrients and the productivity of pea grain in six-field and two-field crop rotations. Among the main factors affecting the yield of pea grain such as the total number of weeds and the content of accumulated nutrients in the 0-30 cm, soil layer were considered. The total number of weeds on two nutritional backgrounds in the pea germination phase was from 102.0 to 137.0. During the ripening period, respectively, it was from 44.0 to 56.0 pcs / m2. The maximum yield of pea grain is observed in crops after soft wheat with ammophos - 1.03 t / ha, without the use of fertilizer - 0.98 t / ha. The lowest yield of peas was obtained after durum wheat in a two-field crop rotation: according to the fertilized nutrition background - 0.76, unfertilized - 0.70 t / ha. As a result of statistical data processing in the third variant of the experiment (sowing peas after soft wheat in the aftereffect of a busy fallow), it was found that the increase in the productivity of pea grain slightly depended on the weediness of crops and the share of its influence ranged from 13.98 to 18.37%. However, the decrease in the yield of peas in the fifth variant of the experiment (sowing peas in alternation with durum wheat) was largely determined by weeds and the level of their influence was from 40.21 to 54.41%. The content of accumulated nitrate nitrogen and mobile phosphorus from ammophos before all sowing of peas in crop rotations ranged from 1.4 to 2.9 mg / 100 g of soil. The increase in pea grain from mineral fertilizers for 18 years, respectively, for all predecessors was 0.07; 0.05; 0.08 and 0.06 t / ha, except for the second variant of the experiment, where peas were sown after soft wheat in the aftereffect of black steam. The results of mathematical processing of the data on the increase in grain of peas show the effect of ammophos on the increase in grain by options in the range from 55.41 to 81.88%.

Abstract In the course of two years of research, the effect of application of liquid nitrogen fertilizer UAN-32, ammophos and diammophos, as well as their combined use, pre-sowing application of solid nitrogen fertilizers - ammonium nitrate and ammonium sulfate - was studied. Studies have shown that under conditions of unstable moisture supply, pre-sowing and starter application of these fertilizers in combination with N69P26 provides a yield of 17.3 c/ha (54.4% increase) N42P42 - 14.1 c/ha (30.5% increase) and N59P42 - 14.8 c/ha (37% increase). The application of UAN-32 at a dose of 150 l/ha with a high supply of soils with phosphorus and potassium increases the yield by 35.7 (15.2 c/ha). The introduction of UAN-32 at a dose of 150 l/ha, against the background of a high soil supply with phosphorus and potassium, increases the yield by 35.7 (15.2 c/ha). The oil yield for these variants increased from 4.6 - 4.61 c/ha to 7.54; 6.1 and 6.51 c/ha, and protein from 2.8-1.77 c/ha to 4.35 and 2.29-2.71 c/ha. Combinations of UAN-32 with ammophos and diammophos contribute to the formation of a higher oil content in seeds, and an increase in the nitrogen dose increases the protein content and yield.

Application of fertilizers combined with nitrification inhibitors affects soil microbial biomass and activity. The objective of this research was to determine the effects of fertilizer application combined with the nitrification inhibitor potassium oxalate (PO) on soil microbial population and activities in nitrogen-poor soil under cotton cultivation in Uzbekistan. Fertilizer treatments were N as urea, P as ammophos, and K as potassium chloride. The nitrification inhibitor PO was added to urea and ammophos at the rate of 2%. Three treatments—N200P140K60(T1), N200P140 POK60(T2), and N200P140 POK60(T3) mg kg-1soil—were applied for this study. The control (C) was without fertilizer and PO. The populations of oligotrophic bacteria, ammonifying bacteria, nitrifying bacteria, denitrifying bacteria, mineral assimilating bacteria, oligonitrophilic bacteria, and bacteria group Azotobacter were determined by the most probable number method. The treatments T2 and T3 increased the number of oligonitrophilic bacteria and utilization mineral forms of nitrogen on the background of reducing number of ammonifying bacteria. T2 and T3 also decreased the number of nitrifying bacteria, denitrifying bacteria, and net nitrification. In conclusion, our experiments showed that PO combined with mineral fertilizer is one of the most promising compounds for inhibiting nitrification rate, which was reflected in the increased availability and efficiency of fertilizer nitrogen to the cotton plants. PO combined with mineral fertilizer has no negative effects on nitrogen-fixing bacteria Azotobacter and oligo-nitrophilic bacteria.

The experiments were carried out in 2018–2021 on ordinary chernozem in the conditions of the Rostov region. The winter barley variety Master was cultivated. The predecessor is corn for grain. Mineral fertilizers included ammonium nitrate (34.4%), ammophos (12-52), nitroammophos (16-16-16). Nitrogen-phosphorus fertilizers (a fertilizer mixture of ammonium nitrate and ammophos) and nitroammophoska (16-16-16) were applied when sowing barley, ammonium nitrate was applied by a surface method randomly in the spring tillering phase. Bacterial preparations contain strains of associative nitrogen-fixing microorganisms: Mizorin, Rizoagrin, Extrasol. They were applied to barley seeds in the pre-sowing period. It has been established that the use of the bacterial preparation Mizorin (600 g/ha) against the background of pre-sowing application of nitrogen-phosphorus fertilizer at a dose of N30P30, nitrogen top dressing with ammonium nitrate at a dose of 30 kg/a.i. ha increased the increase in grain yield on average over three years compared with the control variant (without the use of agrochemicals) by 0.71 t/ha, or 14.4%. The application of the biological preparation Mizorin without mineral fertilizers increased the yield by 0.31 t/ha, or 6.3%, compared to the control variant. In 2019–2021, the average protein content in the grain of winter barley in the control variant was 10.7%, which ensured the collection of protein 525 kg/ha. Against the background of nitrogen-phosphorus fertilizers at a dose of N30P30 and nitrogen supplementation at a dose of 30 kg/ha, the maximum increase in protein content was in the variant using Mizorin, which was 1.1% compared to the control variant, while the protein yield in the crop increased by 138 kg/ha, or by 26.3%.

Исследования проводились в 2021–2022 гг. на полях ТОО «НПЦЗХ им. А.И. Бараева», расположенных в Акмолинской области Северного Казахстана. Цель исследований заключалась в изучении влияния минеральных удобрений при возделывании пшеницы и льна по нулевой и традиционной технологиям на трансформацию органического вещества почвы. Исследованиями уставлено, что при традиционной технологии содержание углерода составляло от 1,89% до 1,92%, в то время как при нулевой технологии этот показатель варьировал от 2,00% до 2,04%. В сравнении с традиционной технологией, при использовании нулевой технологии было в среднем на 0,11% больше углерода в гумусовых веществах (НСР0,05 = 0,05%). Содержание углерода легкоразлагаемого органического вещества при нулевой технологии было выше в 1,2 раз в сравнении с традиционной технологией. Минеральные удобрения повышали содержание углерода лабильного гумуса в почве как при традиционной (на 0,03 %), так и нулевой технологии (на 0,05%). Технологии возделывания и минеральные удобрения не оказывали значительного влияния на содержание углерода гуминовых кислот в почве. Содержание фульфокислот в пахотном слое при традиционной технологии увеличилось с внесением аммофоса в дозе P20 и смеси аммофоса и аммиачной селитры в дозе N20P20 на 0,04 % (НСР0,05 =0,02 %) в сравнении с неудобренным фоном. При использовании нулевой технологии количество фульвокислот увеличилось с внесением аммофоса в дозе P20 на 0,05% (НСР0,05 =0,02 %). The research was carried out in 2021–2022 in the fields of A.I. Baraev LLP NPCKH (wheat and flax crops) located in the Akmola region of Northern Kazakhstan. The purpose of the research was to study the effect of mineral fertilizers during cultivation using zero and traditional technologies on the transformation of soil organic matter. Studies have shown that with traditional technology, the carbon content ranged from 1.89% to 1.92%, while with zero technology, this figure ranged from 2.00% to 2.04%. In comparison with traditional technology, when using zero technology, there was on average of 0.11% more carbon in humic substances (LSD.05 = 0.05%). The carbon content of easily degradable organic matter at zero technology was 1,2 times higher compared to traditional technology. Mineral fertilizers increased the carbon content of labile h Cultivation technologies and mineral fertilizers did not have a significant effect on the carbon content of humic acids in the soil. The content of fulvic acids in the arable layer with traditional technology increased with the addition of ammophos at a dose of P20 and a mixture of ammophos and ammonium nitrate at a dose of N20P20 by 0.04% (LSD.05 = 0.02%) compared with an unfavorable background. When using zero technology, the amount of fulvic acids increased with the addition of ammophos at a dose of P20 by 0.05% (LSD.05 = 0.02%).

The article presents the results of studying the influence of nitrogen and phosphorus fertilizers on the water regime of meadow-chernozem soil, yield and oil content of flax seeds in 2022–2023. on a stationary experiment at the field forage production laboratory of the Federal State Budgetary Institution “Omsk ASC” in the conditions of the southern forest-steppe of the Omsk region. The objects of observation are oilseed flax of the Northern variety and meado-chernozem soil. The scheme of the experiment included the following options: factor A — medium soil availability of mobile phosphorus (50-100 mg/kg according to F.V. Chirikov, background 0), increased (100–120 mg/kg, background I and 140–150 mg/kg, background II), high (150– 200 mg/kg, background III); factor B — phosphorus fertilizer (P0, P60); factor C — nitrogen fertilizer (N0, N30, N60). In this case, nitrogen and phosphorus fertilizers were superimposed on backgrounds of varying soil phosphorus supply. Climatic factors (temperature and precipitation) determined the initial reserve of total moisture in the soil when sowing oil flax, which was at the level of 82% of the lowest moisture capacity in a meter layer and did not depend on the background phosphorus supply. Mineral fertilizers increased crop productivity. Its highest yield was observed against the background of an increased supply of soil with mobile phosphorus (1.71 t/ha) with the pre-sowing application of ammonium nitrate and ammophos. The oil content of flax, on the contrary, decreased when using fertilizers. Its highest indicators (39.5%) were observed against background II when using phosphorus fertilizers.

The article presents the results of studies on the influence of intensification methods on the structural state of leached chernozem of the Krasnoyarsk forest-steppe during the cultivation of spring wheat. It is shown that blocky > 10 mm (26-38%) and lumpy-granular units 2-1 mm in size (15-21 %) predominated in the structural composition of chernozem. The use of the biological stimulant Lignohumate AM in the complex protection of spring wheat against the background of the pre-sowing introduction of ammophos in doses of N5P20 and N12P50 contributed to an increase in the number of 2-1 mm aggregates by 4-5 % compared with the control and the formation of an excellent structural state of chernozem containing aggregates of a valuable size 72- 74% during the growing season.

Background. The need to increase the production facilities of the key sectors of the Russian economy arises as the consequences of the covid condition and is justified by social, economic and food crises. Guarantees of food security are provided due to stability and development of national facilities of the agro-industrial complex. Thus, on the legislative level a strategy to develop chemical networks has been developed. Also, a plan to develop mineral production in the agricultural sector has been made.

The purpose of the research is to develop methods for increasing soil fertility by introducing phosphogypsum on alka-line chernozem in the conditions of the Samara region. The effect of the introduction of various norms of phos-phogypsum (1,5, 3,0, 5,0 t/ha) on alkaline chernozem against the background of N120P60K60 on soil structure, the reac-tion of the soil environment and the content of absorbed bases, and on the formation of winter wheat productivity was studied. Field experiments were laid in 2019-2022 on the territory of a pilot site in the central agroecological zone of the Samara region. The soil is alkaline medium loamy chernozem with a thickness of humus horizon up to 50-60 cm. Phosphogypsum was applied against the background of the use of the mineral fertilizer Ammophos (NH4H2PO4 + (NH4)2HPO4). One half of the calculated norm was introduced by spreading for pre-sowing cultivation, and the second – when sowing through the fertilizer dispenser of the seeder. Field experiments were accompanied by the necessary observations and analyses. When phosphogypsum is applied to the soil, the processes of structure formation are activated, stable granules with a diameter of 1-3 mm are formed in a layer of 0-10 cm, an improvement in the mor-phological structure of the soil is observed. The application of nitrogen fertilizer in combination with phosphogypsum (5 t/ha) contributes to the activation of microbiological processes in the soil by 67-87 %. On natural and elevated backgrounds on alkaline chernozem, the annual application of phosphogypsum and mineral fertilizers at a dose of N40P40K40 improves the supply of soil with mobile compounds of nitrogen, phosphorus, and potassium, increasing the level of effective fertility. The growth and development of cultivated crops increases at a dose of phosphogypsum of 2 t/ha, the yield of winter wheat significantly increases (by 19.3%).

Field experiments on ordinary black soil were conducted in 2018-2021 in the Rostov region. The object of research was a variety of winter barley Master. The predecessor is corn for grain. Bacte-rial preparations developed at the All-Russian Institute of Agricultural Microbiology (VNIISHM) in St. Petersburg contain strains of associative microorganisms-nitrogen fixators: Mizorin, Ri-zoagrin, Extrasol. They were applied to barley seeds in the pre-sowing period. It was found that the use of Mizorin (600 g /ha) for seed treatment before sowing against the background of a near-sowing application of nitrogen-phosphorus fertilizer in the form of a mixture of ammophos and ammonium nitrate at a dose of N30P30, nitrogen fertilization by a scattered surface method with ammonium nitrate at a dose of 30 kg/ ha of the active substance increased the increase in grain yield on average for 3 years compared with the control variant by 0.71 t/ ha or by 14.4%. The use of the biological preparation Mizorin without mineral fertilizers against the background of natural soil fertility increased the yield compared to the control variant by 0.31 t /ha or by 6.3%. On av-erage, in 2019-2021, the protein content in winter barley grain in the control variant was 10.7%, which provided a protein harvest equal to 528 kg/ha. Against the background of nitrogen-phosphorus fertilizers at a dose of N30P30 and nitrogen fertilizing at a dose of 30 kg / ha, the max-imum increase in protein content was obtained in the variant with the use of Mizorin, which compared to the control variant was 1.1%, while the protein harvest increased by 138 kg/ha or 26.1%.

The article presents the results of the economic and bioenergetic assessment of winter barley cultivation methods for harvesting bulky fodder. In a short-term experiment the effect of five levels of mineral nutrition on two methods of tillage in the crop rotation link soybean – winter barley, on fused leached chernozems of the southern foothill zone of Adygea has been studied. Differentdepth methods of tillage have been used for 20–22 cm (plowing) and 12–16 cm (surface tillage). As a background on the variants, the main fertilizer ammophos and ammonium nitrate have been used as top dressings (N30; N45; N60). It has been revealed that the use of surface treatment reduces the yield of winter barley green mass by 21-41%. The average yield varied from 8.8 for surface tillage to 12.8 t/ha for plowing. The highest level of productivity is 19.2 for plowing and 12.0 t/ha for surface treatment. It has been revealed that the green mass of the studied varieties of winter barley in 1 kg of natural feed contains, on average, from 0.42 to 0.605 EFU (energy feed units). Analysis of the nutritional value of the obtained green mass has shown: in 1 kg of dry matter of feed for plowing: crude protein 10.1%, exchange energy 11.72 MJ, feed units (Ke) 1.12; for surface treatment – 8.8%, 11.72 MJ, 1.13 (Ke). The highest yield has been formed according to the cultivation method, with the introduction of 60 kg of a.i. N by background (N24 P104) – by plowing. The most profitable plowing option is: Background + N60 (Romans variety), with a yield of 19.2 t / ha, the profit from the sale is 10603.8 thousand rubles, the profitability level is 58.3%. Bioenergetic assessment of cultivation methods has shown that for each unit of energy invested in the production of winter barley green mass, on the best options, from 2.75 to 2.92 units of energy have been obtained.

Full textAbstract:
The results of long-term (1968-2021) experiment on the use of fertilizers for the 10th and 11th rotations of grain and fallow crop rotation in the experimental field of the Kurgan region are presented. Crop rotation included fallow and three crops of wheat. Fertilizer efficiency varied depending on the combination of the nutrients, the place of wheat in the rotation, and the moisture conditions of the growing season. Moderate effect of phosphorus fertilizer and high effect of nitrogen fertilizer on heavy loamy leached chernozem of the experimental field in these rotations was observed on the crops distant from the fallow. The combination of nitrogen and phosphorus fertilizers gave a higher yield increase. Nitrogen fertilizer also had a positive effect on the quality of wheat, increasing the gluten content and the thousand-kernel weight. With the increase of gluten accumulation in wheat grain against the background of nitrogen fertilizer, the repeatability of wheat quality compliance with the requirements for the 3rd class of grain increased. The effect of fertilizers and the duration of their application on the agrochemical properties of soil became visible. The content of mobile nutrients, humus, total nitrogen and phosphorus increased more noticeably with the use of fertilizers, but the рНsan value decreased. High economic efficiency related to nitrogen fertilizer applied on the second and third wheat after fallow with a payback of 1 kg of nitrogen 12-19 kg of grain. The effect of phosphorus fertilizer was moderate, since the content of mobile Р2О5 in the topsoil remained high. The use of ammophos had a stronger effect on the yield of wheat when the plants were well supplied with nitrogen in the first fallow crops.

The article presents the results of field experiments on the effect of mineral fertilizers and bacterial preparations on the yield and quality of safflower seeds. Studies were conducted in 2016-2018 in the North-Eastern zone of the Rostov region on dark chestnut soils. The object of research was the variety of safflower Zavolzhsky-1. Predecessor was winter wheat. As mineral fertilizers, ammonium nitrate and ammophos were used in various doses, according to the scheme of experience, which were introduced simultaneously with sowing or randomly for presowing cultivation. The bacterial preparations were presented to the associative nitrogen-fixing bacteria of the strains Minorin, Flavobacterium, KL-10 production research center of Pushkin. In the field experiment, the variants of the joint application of mineral fertilizers and pre-sowing treatment of seeds with bacterial preparations were also studied. The control was an option without the use of mineral fertilizers and bacterial preparations. The research methodology is standard for studying the action of fertilizers. The average seed yield of safflower on the options amounted to 1,03-1,22 t/ha, oil content of seeds of 35.9-36.3 percent, and the yield of oil yield of seeds from 1 ha – 337-398 kg. In the course of research, we have found that the optimal dose of mineral fertilizers, providing the greatest yield and yield of oil in harvest – introduction of scattering under the sowing cultivation at a dose of N48P52. The increase to the control variant was 18.4%. The yield of oil was increased by 23.7%. The bacterial preparation with associative strains of nitrogen-fixing bacteria for use on natural background fertility of the soil Flavobacterium was identified. The increase in the yield of oilseeds was 13.6%, oil collection was 18.1%.

The results of field experiments to study the effect of mineral fertilizers and bacterial preparations on the yield and quality of sunflower seeds are presented. The studies were carried out in 2011–2014 in the Rostov region on medium-power ordinary chernozem. The object of research was a hybrid of sunflower Patriot. The predecessor is winter wheat. Ammonium nitrate, ammophos and potassium chloride in various doses were used as mineral fertilizers, according to the experimental scheme. Fertilizers were introduced before sowing, before the main tillage and pre-sowing cultivation. Bacterial preparations were represented by associative nitrogen fixers of the strains Mizorin, Flavobacterin, PG-5 and 17-1 produced by the All-Russian Scientific Research Institute of Agricultural Medicine, Pushkin. In the field experiment, variants of the joint application of mineral fertilizers and presowing treatment of seeds with bacterial preparations were also studied. The control was the variant without the application of mineral fertilizers and bacterial preparations. The Patriot sunflower hybrid seed yield in the control variant on average for 3 years amounted to 1.61 t/ha. A significant increase in the yield of sunflower seeds and oil gathering was established in the variant with pre-sowing application of mineral fertilizers in a dose of N40P50. The increase compared to the control variant was 0.53 t/ha, or 34.2%, and in the oil gathering in the crop - 226 kg/ha, or 36.4%. The application of biologics of associative nitrogen fixers contributed to an increase in the yield of sunflower seeds. Inoculation of sunflower seeds with a strain of the biological preparation PG-5 was more effective. The increase in the yield of sunflower seeds amounted to 0.44 t/ha, or 28.6% compared to the variant without the application of fertilizers. The increase in the oil gathering in the crop was by 29.3%. The application of bacterial preparations under sunflower against a background of nitrogen-phosphorus fertilizers was ineffective.

Gluten, protein and amino acid composition play an important role in grain quality assessment. Areas of interest of our research include essential amino acids, which are not synthesized in the human body. It is a commonly known fact that large doses of mineral fertilizers increase grain crops’ yield and quality. However, fertilization leads to undesirable effects—in particular, environmental pollution. This creates a need to replace mineral fertilizers, at least partially, with alternative methods. One such method is the use of microbial preparations in modern technologies for growing cereals. This research, therefore, aimed to study the effect of presowing seed inoculation with a microbial preparation (based on phosphate-mobilizing bacterium Lelliottia nimipressuralis CCM* 32-3) on T. aestivum grain quality, namely the content of gluten, protein and amino acids. The analysis of three-year field experiments showed that the highest values were obtained when using the microbial preparation against the background of mineral fertilizers at the rate of P30. Presowing seed inoculation contributed to a significant increase in grain productivity (by 31.5% compared to control). The content of protein and gluten in the grain also increased up to 12.5 % and 28.0%, while in the control, these figures were 10.8% and 21.2%, respectively. Moreover, the total content of amino acids in wheat grain in the variant inoculation + fertilizers (P30) was the highest compared to those without inoculation. The following excess was noted: by 52% compared to control (without fertilizers); and by 29%, 17% and 10% in variants with mineral fertilizers at the rate of P30, P60, and P90, respectively. The obtained research results indicate that the combined application of mineral fertilizer Ammophos (at the rate of P30) and microbial preparation based on the phosphate-mobilizing bacterium L. nimipressuralis CCM 32-3 for presowing seed inoculation is an effective technique that improves the yield and quality indicators of winter wheat grain under the conditions of southern regions with insufficient moisture supply.

The purpose of the research is to develop ways of soil reclamation applying phosphogypsum for spring barley crops on chernozemic soil growing under the conditions of the central agro-climatic zone of the Samara region. The studies were conducted in 2019-2021. The soil is ordinary medium loamy chernozemic with A1 horizon up to 50-60 cm. Full shoots of spring barley of the Berkut variety under the conditions of the central agro-climatic zone of the Samara re-gion come up on the 7th day after seeding have been performed, there is no effect on this process both of mineral fertilizers and phosphogypsum. Their influence begins to manifest itself later. The introduction of phosphogypsum into the soil at a rate of 1.5-4.5 t / ha increases the vegetation of spring barley by 3-4 days, the use of phosphogypsum at a rate of 6.0 t / ha – by 5 days. The introduction of phosphogypsum into the soil against the background of the use of Ammophos in the norm of 100 kg/ha in gross weight, or 12 kg /ha – N and 52 kg/ha – P2O5 of the primary material, contributes to an increase of grain, on average by 5.9-9.5% – up to 710-734 g/l, the content of fat and ash in abso-lutely dry matter, respectively by 3.4-14.2 and 4.5-20.3% and free nitrogen extract – с 69.2% до 72.7%. The maxi-mum values of these indicators were noted on the variants with the introduction of phosphogypsum 4.5 and 6.0 t per 1 ha. Economically, it is most expedient to apply phosphogypsum at a rate of 4.5 t/ha for spring barley of the Berkut variety on ordinary chernozemic soil of the central agro-climatic zone of the Samara region. The use of the above norm of phosphogypsum (6.0 t/ha) does not provide a significant increase of yield, leads to an increase of the produc-tion cost, a decrease of profitability of works and inefficient use of ameliorant.

Solving the problem of increasing pea yield is one of the main tasks of crop production in the arid conditions of the Orenburg-Cis-Ural region. The most optimal solution is to use pea crops after applying ammophoska for fall plowing in grain-fallow crop rotations and to identify the effect of factors on grain yield. Adding chopped straw and green manure to the soil of pea predecessors without mineral fertilizers does not solve the problem. Conducting field experiments and statistical analysis (regression) of the results obtained is timely and relevant. The aim of the study is to determine the effect of weather conditions, soil productive moisture and nutrients, weeds and precursors of crop rotation on pea yield by nutritional backgrounds in the arid conditions of the Orenburg Region. On the territory of the experimental production farm named after Kuybyshev, Orenburg Region, pea crops (2002–2022) are being studied in 6-field and 2-field crop rotations on a longterm stationary experimental plot established in 1990. The repetition of the two-factor experiment is fourfold in the area and twentyfold in time. Factor A is backgrounds: fertilized (ammophoska – N40P40K40 kg/ha) and unfertilized (control). Factor B is options: five pea predecessors (two durum and three soft wheat) of crop rotations. Average data were obtained: air temperature for May-August is +16.2…+22.8°C; precipitation – 21.7–42.7 mm; number of dry days – 14–18; hydrothermal coefficient (HTC) – 0.09–0.19; productive moisture content after sowing – 126.9–137.9 mm, before harvesting – 32.2–51.2 mm, consumption – 170.7–179.6 mm; N-NO3 on a fertilized nutritional background – 84–101, 55–86, 9–30 mg and on an unfertilized background – 66–76, 45–74, 1–25 mg; P2O5–58–63, 52–60, 0–7 mg and 43–46, 37–45, 0–7 mg; K2O – 423–500, 367–454, 42–56 mg and 382–425, 329–404, 13–53 mg/kg; the number of weeds in the germination phase – 91–139 and 84–109 pcs., in the ripening phase – 40–58 and 37–49 pcs./m2; the mass of weeds – 35.8–47.1 and 33.8–42, 2 g/m2; yield – 0.65–0.87 and 0.60–0.83 t/ha; increase in pea grain – 0.01–0.06 t. The observations revealed an increase in pea yield by nutritional backgrounds in a six-field crop rotation with summer sowing of Sudan grass, depending on the effect of June precipitation, ammophoska and the precursor of soft wheat. Lack of precipitation in June, spent moisture, nitrate nitrogen and weeds significantly reduced pea yield after durum wheat in a two-field crop rotation. The experimental variants revealed a significant effect of dry weather conditions, use of productive moisture, soil nutrient imbalance and weed infestation on pea yield reduction in grainfallow and green manure rotations. The effect of other factors combined was insignificant.

In the steppe zone of the Omsk region from 2020 to 2022 two sowing periods (May, 15 and 25) of Severny oilseed flax with a seeding rate of five million germinated seeds per hectare on four chemicalization backgrounds were tested. With the norm for the steppe zone of the HTC 0.78 all the years of the experiments this indicator was only 0.37-0.58. Having sowed in the third decade of May, the yield of oilseed flax seeds with the use of a tank mixture of herbicides (Agritox, WC 1 l/ha and Legion, EC 0,4 l/ha) with a working fluid flow rate of 200 l/ha 0.868 tons of oilseeds were obtained from 1 ha and 1.009 t/ha were obtained with the help of a complex chemicalization, where Lingohumate 100 g/ha was used during the leaf development phase in a mixture of herbicides and Isagry Bor 0.5 l/ha during the building phase. They provided a profitability level of 197 %. Similar results were obtained having used only herbicides – 179.9 %. Ammophos’s introduction during sowing did not bring a significant increase in yield and reduced economic indicators. Having sowed in the second decade of May, the annual oilseeds yield was significantly lower and, accordingly, the level of profitability was decreasing sharply from 27.8 to 87.8 %.

В исследованиях Курганского НИИСХ - филиала ФГБНУ УрФАНИЦ УроРАН было сравнено влияние на урожайность и качество зерна яровой пшеницы действия и последействия фосфорных удобрений при разных уровнях внесения азотного удобрения в вариантах: 1) без фосфорного удобрения, 2) на фоне последействия многолетнего применения суперфосфата (Р21) 3) на фоне Р21 с последующим 10-летним внесением аммофоса (Р26). Возобновление применения фосфорного удобрения содействовало увеличению накопления клейковинных белков в зерне пшеницы на 1-2 процентных пункта (п. п.) в среднем за 2008-2017 гг., а в 2011 и 2012 гг. - на 6-7 п. п. к применению одного азота. Увеличение сбора клейковины, обусловленное как прибавкой урожая, так и повышением содержания клейковины в зерне, на фоне Р26 было существенно выше по отношению к фону Р21. Положительное действие фосфора заметнее проявлялось при недостатке влаги, когда растения активнее используют фосфор из гранул удобрения, чем из запасов высохшей почвы. In the studies conducted in the Kurgan research Institute of agriculture - branch of FSBSI UrFASRC, UrB RAS the effect and aftereffect of phosphorus fertilizers on the yield and grain quality of spring wheat at different levels of nitrogen fertilizer are compared in the variants: 1) without phosphorus fertilizer, 2) on the background of the aftereffect of long-term application of superphosphate (P21), 3) on the background of P21 with subsequent 10-year additional fertilization with ammophos (Р26). The resumption of the use of phosphorus fertilizer contributed to an increase in the accumulation of gluten proteins in the wheat grain by 1-2 percentage points (p. p.) on average for 2008-2017, and in 2011 and 2012 by 6-7 p. p. versus the separate use of nitrogen. The increase in gluten harvest, due to both the increase in yield and the increase in gluten content in grain, against the background of P26 was significantly higher compared to the background of P21. The positive effect of phosphorus was more noticeable when there was a lack of moisture, when the plants make more use of phosphorus from fertilizer granules than from stocks of dried soil.

Изучали влияние доз минеральных удобрений и систем обработки лугово-каштановой почвы на урожайность и качество зерна нового сорта озимой твердой пшеницы Крупинка. Исследования проводились на опытной станции имени Кирова – филиал ФГБНУ «ФАНЦ РД» в условиях орошения. Сорт высевали на трех уровнях минерального питания: 1. Без удобрения (контроль), 2. N90 P50 (N10 P50 аммофоса под основную обработку N30 аммиачной селитры, в фазе кущения N30 - выхода в трубку, N20 карбомида в фазе колошения), 3. N180 P100 (N120 P100 под основную обработку, N60 – в фазе кущения, N60 – в фазе выхода в трубку, N40 – в фазе колошения). Эффективность доз минеральных удобрений изучали на фоне двух систем обработки почвы: поливного полупара (контроль) и полупаровой системы обработки почвы: 1- а) проведение влагозарядкового полива вслед за уборкой предшественника, с использованием оставшейся оросительной сети нормой 1200 м3/га; б) 2-3 дискования на 12-15 см по мере отрастания сорняков, июль-август (ДТ-75М+БДТ-3); в) отвальная вспашка на 20-22 см в начале второй декады сентября (Т-150+ПЛН-4-35); г) продольно- поперечные дискования с одновременным боронованием во второй декаде сентября (ДТ-75М+БДТ-3+3БЗСС1). 2- полупаровая система обработки почвы: - а) лущение стерни на глубину 6-8 см, вслед за уборкой предшественника (Т-150+ЛДГ-5); б) отвальная вспашка на 20-22 см в третьей декаде июля (Т-150+ПНЛ-6-35); в) выравнивание поверхности почвы малой-выравнивателем (МВ-6), после вспашки; г) влагозарядковый полив нормой 1200 м3/га в третьей декаде августа; д) дискование на 12-15 см с одновременным боронованием перед посевом (ДТ-75М+БДТ-3+3БЗСС-1). Максимальная урожайность озимой твердой пшеницы – 5,58 т/га, в среднем за 2015-2018 гг., достигнута в варианте внесения повышенной дозы минеральных удобрений (N180P100) на фоне полупаровой системы обработки почвы, что на 44,8% больше, чем на контроле (без удобрения). Применение системы обработки почвы по типу поливного полупара приводило к снижению урожайности в варианте внесения повышенной дозы минеральных удобрений (N180P100) по сравнению с полупаровой системой на 0,49 т/га, или на 8,8 %. The influence of doses of mineral fertilizers and meadow-chestnut soil treatment systems on the yield and quality of grain of a new variety of winter durum wheat Krupinka was studied. The research was carried out in the Kirov Experimental Station - a branch of the FGBNU "FANC RD" on heavy loamy soil in irrigation conditions. The variety was sown at three levels of mineral nutrition: 1. Without fertilizer (control), 2. N90 P50 (N10 P50 ammophos for the main treatment of ammonium nitrate N30, in the tillering phase N30 - exit into the tube, N20 carbomide in the earing phase), 3. N180 P100 (N120 P100 for main processing, N60 in tillering phase, N60 in tube outlet phase, N40 in ear phase). The effectiveness of mineral fertilizer doses was studied against the background of two tillage systems: irrigation semi-steam (control) and semi-steam tillage system: 1- a) moisture-charging irrigation following the harvesting of the predecessor, using the remaining irrigation network at a rate of 1200 m3 / ha; b) 2-3 discs of 12-15 cm as the weeds grow back, July-August (DT-75M+BDT-3); c) dump ploughing by 20-22 cm at the beginning of the second decade of September (T-150 + PLN-4-35); d) longitudinal-transverse disking with simultaneous harrowing in the second decade of September (DT-75M + BDT-3 + 3BZSS1). 2- semi-steam tillage system: - a) peeling of stubble to a depth of 6-8 cm, following the harvesting of the predecessor (T-150 + LDH-5); b) dump ploughing by 20-22 cm in the third decade of July (T-150 + PNL-6-35); c) leveling of the soil surface with a small leveler (MV-6), after plowing; d) moisture-charging irrigation with a norm of 1200 m3 / ha in the third decade of August; e) disking by 12-15 cm with simultaneous harrowing before sowing (DT-75M + BDT-3 + 3BZSS-1). The maximum yield of winter durum wheat - 5.58 t / ha, on average for 2015-2018, was achieved in the option of applying an increased dose of mineral fertilizers (N180P100) against the background of a semi-steam tillage system, which is 44.8% more than on the control (without fertilizer). The use of a tillage system of the type of irrigation semi-steam led to a decrease in yield in the option of applying an increased dose of mineral fertilizers (N180P100) compared to a semi-steam system by 0.49 t / ha, or by 8.8%.

Full textAbstract:
На опытной станции имени Кирова – филиал «ФГБНУ ФАНЦ РД» изучена продуктивность новых перспективных сортов озимой пшеницы (Гром, Васса, Сила, Таня), селекции «НЦЗ имени П.П. Лукъяненко». Почва опытного участка лугово-каштановая тяжелосуглинистая. Цель исследований заключалась в изучении элементов ресурсосбережения высокоурожайных сортов озимой пшеницы в условиях орошения равнинной зоны Дагестана. Сорта озимой пшеницы высевали на трех уровнях минерального питания: 1- без удобрения (контроль); 2 - N90P50 (N10P50 аммофоса под основную обработку, N30 аммиачной селитры - в фазе кущения, N30- выхода в трубку, N20 карбамида - в фазе колошения; 3- N180P100 (N20P100 под основную обработку, N60- в фазе кущения, N60- в фазе выхода в трубку, N40- в фазе колошения). Изучали две системы обработки почвы: система поливного полупара (контроль), влагозарядковый полив вслед за уборкой озимой пшеницы с использованием оставшейся после предшественника оросительной сети нормой 1200 м3/га; б) 2 - 3 дискования по мере отрастания сорняков (июль-август); в) отвальная вспашка на 20-22 см в начале второй декады сентября; г) продольно – поперечные дискования с одновременным боронованием во второй декаде сентября; полупаровая система обработки почвы – а) лущение стерни на глубину 6 – 8 см; б) отвальная вспашка на 20-22 см в третьей декаде июля; в) выравнивание поверхности почвы малой - выравнивателем; г) полив нормой 1200 м3/га в третьей декаде августа; д) дискование с одновременным боронованием. Новизна исследований состоит в том, что впервые в условиях Терско-Сулакской подпровинции Дагестана, экспериментальным путем установлена оптимальная доза минеральных удобрений под озимую пшеницу и определена адаптивная система обработки лугово-каштановой почвы в условиях орошения. Исследования показали, что наиболее высокую урожайность 7,6 т/га, в среднем за 2013-2015 гг., обеспечил сорт Гром, при внесении повышенной дозы минеральных удобрений (N180P100) на фоне полупаровой системы обработки почвы. На контрольном варианте урожайность составила (сорт Таня) 5,6 т/га. Другие сорта также уступали сорту Гром по урожайности зерна в оптимальном варианте: Васса на 1,1 т/га, Сила на 1,4 т/га. Однако в экономическом отношении наиболее эффективной оказалась доза N90P50, где чистого дохода получено на 1200 руб. больше, чем в варианте, где получен наиболее высокий урожай зерна (7,6 т/га). In the Kirov experimental station - a branch of the "FSBSI FASC RD" the productivity of new promising varieties of winter wheat (Grom, Vassa, Sila, Tanya), selection "NHZ named after P.P. Lukyanenko" was studied. The soil of the experimental site is meadow-chestnut heavy loamy. The purpose of the research was to study the elements of resource saving of high-yielding varieties of winter wheat in the irrigation conditions of the plain zone of Dagestan. Winter wheat varieties were sown at three levels of mineral nutrition: 1- without fertilizer (control); 2 - N90P50 (N10P50 ammophos for main treatment, N30 ammonium nitrate - in the tillering phase, N30 - exit into the tube, N20 - in the earing phase; 3 - N180P100 (N20P100 for main treatment, N60 - in the tillering phase, N60 - in the tube outlet phase, N40 - in the earing phase). Two soil treatment systems were studied: irrigation semi-evaporation system (control), moisture-charging irrigation after harvesting winter wheat using the norm of 1200 m3 / ha remaining after the predecessor; b) 2 - 3 disks as the weeds grow (July-August); c) dump ploughing by 20-22 cm at the beginning of the second decade of September; d) longitudinal -transverse disking with simultaneous harrowing in the second decade of September; semi-steam tillage system – a) peeling of stubble to a depth of 6 – 8 cm; b) dump ploughing by 20-22 cm in the third decade of July; c) leveling of the surface of the soil with a small leveler; d) watering with a rate of 1200 m3 / ha in the third decade of August; e) disking with simultaneous harrowing. The novelty of the research lies in the fact that for the first time in the conditions of the Tersk-Sulak subprovince of Dagestan, the optimal dose of mineral fertilizers for winter wheat was established experimentally and an adaptive system for processing meadow-chestnut soil under irrigation conditions was determined. Studies have shown that the highest yield of 7.6 tons / ha, on average for 2013-2015, was provided by the Grom variety, with the introduction of an increased dose of mineral fertilizers (N180P100) against the background of a semi-steam tillage system. On the control version, the yield was (Tanya variety) 5.6 t / ha. Other varieties were also inferior to the Grom variety in terms of grain yield in the optimal version: Vassa by 1.1 t / ha, Sila by 1.4 t / ha. However, in economic terms, the dose of N90P50 turned out to be the most effective, where the net income was obtained by 1200 rubles. more than in the version where the highest grain yield was obtained (7.6 tons / ha).
