Investigations carried out under conditions of meadow alluvial soils in the southern zone of the Republic of Karakalpakstan have determined the effectiveness of various norms of mineral fertilizers (N160P100K75; N200P140K100 and N240P170K125 kg / ha) applied to cotton grown in the following year after winter wheat and as a secondary crop of mung beet against mineral fertilizers (N30P80K60 kg/ha). When cotton was grown in the following year after winter wheat and the second crop of mung beans, the highest yield of raw cotton was obtained, which was 3.4 t/ha against the background of mineral nutrition N200P140K100 kg / ha. As a result of research, in the system of crop rotation, winter wheat-recurrent cotton culture is scientifically grounded in the effectiveness of the agro technical method of locating the mung beans culture before sowing cotton.

The Cost

In modern socio-economic conditions, the production of high-quality grain remains the main task of agricultural production. The main way to solve it is to increase productivity by introducing new varieties and crops with high potential and improving the cultivation technology with minimal costs. Agrarians of the North-East of the Non-Chernozem Zone of Russia, having in their land, use poorly fertile sod-podzolic soils of varying degrees of cultivation. To increase the productivity of grain crops, they use adapted resource-saving technologies, in which the level of mineral fertilizer is determined by the magnitude of the dose of the nutrient established experimentally. The high productivity of the variety, along with the quality of the grain, is the most important indicator of the ultimate goal of every breeder. To assess the economic efficiency of the cultivation of spring triticale, studies were carried out on nine varieties: Saur, Dobroe, Zaozerye, KNIISH 9, KNIISH 11, KNIISH 22, Savva, Timur, Rovnya. The results of our studies convincingly indicate that in the conditions of the republic, even against an unfertilized background, cultivated varieties of spring triticale, provide grain yield from 2.5 to 3.8 t/ha. Some of the most important economic indicators characterizing production efficiency are such indicators as the cost of production and the degree of efficiency of grain production, expressed by the level of profitability. The main application of mineral fertilizers (N60P60K60, (P60K60) and the introduction of nitrogen fertilization in tillering at a dose of N30 increases the cost of 1 kg of grain by 5-8%, thereby reducing the profitability of production when cultivating varieties. The cultivation of varieties Rovnya, Zaur, Zaozerye, KNIISH 22, KNIISH 11, Timur was economically profitable, but less profitable than varieties KNIISH 9, Dobroe and Savva. The cost of production of a kilogram of grain was on the option without mineral nutrition from 5.1; 7.0; 5.9; 5.1; 4.8; and 6.4 rubles, respectively. On fertilized options, the cost decreased to a minimum of 4.1 rubles in the Timur variety with the main application of N60P60K60 with nitrogen fertilization N30 during tillering. The maximum increase in the cost price was shown by the varieties Timur, Zaozerye: 4.8 and 4.9 rubles against the background of the main application of N60P60K60. On average for 2020 according to the results of economic analysis, the lowest cost price and the highest level of profitability indicator are observed when cultivating varieties KNIISH 9, Dobroe and Savva at all levels of mineral nutrition.

Cultivation Techniques

Основным направлением повышения качества зерна является выведение новых сортов, генетически предрасположенных формировать зерно с высоким качеством. Вместе с тем, генетический потенциал сортов способен реализовываться только при конкретных погодных условиях и применении приемов возделывания, благоприятно влияющих на рост и развитие растений. В настоящих исследованиях путем изменения режимов питания растений создавали различные условия для того, чтобы определить возможности сортов формировать урожай зерна с большим содержанием белка. Цель работы оценить и выделить сорта озимой пшеницы, способные реализовать потенциал качества зерна при различных уровнях интенсификации минерального питания. Для достижения цели был заложен двухфакторный полевой опыт. Фактор А сорта озимой пшеницы, фактор В уровни минерального питания. В результате установлено, что сорта озимой пшеницы характеризуются неодинаковыми свойствами накапливать белок в зерне. Высокой активностью накапливать белок при внесении удобрений характеризуется сорт Клавдия 2. Средней активностью сорта Безенчукская 380, Московская 56 и низкой Немчиновская 57, Скипетр и Фатинья. Внесение минеральных удобрений из расчета N16 P16 K16 при посеве осенью и N68 в подкормку весной способствует формированию зерна с более высоким содержанием белка у всех сортов озимой пшеницы.The main direction of improving the quality of grain is the cultivation of new varieties genetically predisposed to form high quality grain. At the same time, the genetic potential of varieties can only be realized under specific weather conditions and the application of cultivation techniques that favourably affect the growth and development of plants. In these studies, various conditions were created by changing plant nutritional regimes in order to determine the possibilities of varieties to form a grain crop with a high protein content. The purpose of the work was to evaluate and highlight varieties of winter wheat that can realize the potential of grain quality at various levels of intensification of mineral nutrition. To achieve the goal, a two-factor field experiment was carried out. Factor A - winter wheat varieties, factor B - levels of mineral nutrition. As a result, it was established that varieties of winter wheat were characterized by unequal properties to accumulate protein in grain. Variety Claudia 2 was characterized by high activity to accumulate protein when fertilizing. Bezenchukskaya 380, Moskovskaya 56 were characterized by medium activity and Nemchinovskaya 57, Scepter and Fatigna - by low. The application of mineral fertilizers at the rate of N16 P16 K16 during sowing in fall and N68 for top dressing in spring contributed to the formation of grain with a higher protein content in all varieties of winter wheat.

The aim of the research was to study the effect of the inclusion of different types of perennial leguminous plants as winter wheat precursors in the crop rotation on the rate of accumulation of heavy metals in the soil compared to traditional winter wheat predecessors. The objectives of the research are to develop measures to reduce the accumulation of heavy metals in agricultural soils under conditions of modern crop rotation, limited by the number of crops grown and winter wheat. The accumulations of heavy metals in soils were calculated during the cultivation of the main crops of crop rotation with intensive fertilizer. The concentration of heavy metals in the soil was determined before and after the cultivation of legume precursors. Field studies were carried out during 2013-2017. On gray podzolized medium loamy soils of the Agronomichesky Research Institute of Vinnytsia National Agrarian University. We calculated the volumes of heavy metals with optimal rates of mineral fertilizer application for the most common types of crops grown in crop rotation. Four types of perennial grasses were sown: sowing alfalfa, meadow clover, horned lamb, sainfoin and eastern goatskin. After their four years of use, winter wheat was sown. The control was the predecessors in the following sequence: winter wheat - sunflower - winter wheat - corn. Laboratory studies of the content of mobile forms of heavy metals in soil were carried out in the Vinnytsia branch of the State Center for the Protection of Soil Fertility. Analysis of soil contamination with heavy metals during fertilization of major cereals showed that the amount of mineral fertilizers is from 257 kg/ha to 571 kg/ha for ammonium nitrate, from 175 to 225 kg/ha for double superphosphate and from 58 to 75 kg/ha on potassium chloride. According to the volume of mineral fertilizers used in the cultivation of winter wheat, 1944 mg / ha of lead and 339 mg / ha of cadmium enter the soil. Of these, with ammonium nitrate - 51.4% and 7.4%, respectively, with double superphosphate - 39.6% and 41.3% and with potassium chloride - 9.0% and 51.3%. When growing corn per 1 ha with mineral fertilizers, 2357 mg of lead and 434 mg of cadmium are applied, of which with ammonium nitrate - 48.4% and 6.7%, respectively, with double superphosphate - 42% and 41% and with potassium chloride. - 9.6% and 51.8%. Cultivation of spring barley leads to the receipt of mineral fertilizers to soils 1458 mg/ha of lead and 327 mg/ha of cadmium, of which with ammonium nitrate - respectively 35.2% and 4.0%, with double superphosphate - 52.8% and 42.8% and with potassium chloride - 12.0% and 53.2%. Mineral fertilization of winter rape leads to the entry into the soil per 1 ha of 2223 mg of lead and 390 mg of cadmium, of which with ammonium nitrate - respectively 51.4% and 7.4%, with double superphosphate - 39.6% and 41% and with potassium chloride - 9.0% and 51.5%. With mineral fertilizers for growing sunflower in the soil per 1 ha gets 2073 mg of lead and 427 mg of cadmium, of which with ammonium nitrate - respectively 41.4% and 5.2%, double superphosphate - 47.8% and 42.2 % and potassium chloride - 10.8% and 52.6%. The positive effect of growing leguminous perennial herbs on the decrease in the concentration of heavy metals in the soil and grain of winter wheat has been established. Under the conditions of intensive farming by Vinnitskaya, lead and cadmium fall into the soil for the use of mineral fertilizers in accordance with 1944 mg/ha and 339 mg/ha for growing winter wheat, 2357 mg/ha and 434 mg/ha for growing corn, 1458 mg/ha and 327 mg/ha when growing spring barley, 2223 mg/ha and 390 mg/ha when growing sunflower. The four-year cultivation of perennial leguminous grasses under intensive farming reduced the concentration of lead in the soil from 1.33 to 3.2 times and cadmium from 37 to 54 times compared with cereal crops, which contributed to improving the quality of winter wheat grain by reducing the concentration of lead from 1 7 to 2.4 times and cadmium from 1.4 times to 2.1 times. Key words: legumes, precursors, winter wheat, heavy metals, pollution.

Studies have been carried out with the identification of criteria for the anthropogenic stability of agro-gray forest soils according to the main indicators of biological activity under conditions of intensive farming. Soils of this type are dominant in the soil cover of the Republic of Tatarstan, so the results of the experiment can be widely interpolated to similar conditions of soil formation and serve as quickly defined markers for diagnosing anthropogenic pressure. Studies have been carried out in field crop rotation since 1992, using various doses of potassium at three levels of soil nitrogen supply. As a result of long-term use of fertilizers, changes in microbiological activity have been revealed, in the variant with the use of environmentally balanced doses of mineral nutrition, an increase in microorganisms from 3,400 thousand (control) to 4,000 thousand per 1 g of soil is observed. A subsequent increase in the dose of fertilizers led to a decrease in the number of microorganisms relative to the control. Under the influence of the optimal combination of fertilizers (option 3), conditions for the development of actinomycetes, ammonifiers, nitrifiers, cellulose-decomposing bacteria are improved, while very high doses of mineral fertilizers (N180P60K200) worsen them, indicating a decrease in the activity of beneficial bacterial microflora. This leads to a slowdown in decomposition of fiber, nitrification and other biochemical processes. Indicators of the biological activity of the soil correlate among themselves, as well as with other indicators of its fertility, with the productivity of crop rotation and therefore can serve as an additional diagnostic sign when assessing the anthropogenic stability of the agricultural soil of the agricultural soil in intensive agriculture.

Organic Carbon Content

The paper presents the results of over 30-years of field experiment on soil organic carbon accumulation under different crop rotation, manure and mineral N fertilization. The experiment was conducted with two crop rotations: A – recognized as soil exhausting from humus (potatoes, winter wheat, spring barley and corn) and B enriching soil with humus (potatoes, winter wheat, spring barley, and clover with grass mixture). In each crop rotation, five rates of manure – 0, 20, 40, 60 and 80 t/ha and four rates of mineral fertilizers N1, N2, N3 and N4 were applied. At the beginning of the experiment in 1979, the initial organic carbon content amounted to 0.74%, and after 33 years dropped to 0.61% in crop rotation without legumes. On the contrary, in crop rotation with clover – grass mixture, the tendency to stabilization of organic carbon quantity in soil was observed with the highest value 0.79% and the lowest one 0.72%. It was found that crop rotation enriching soil with humus produced organic matter ever more than those depleting the soil with humus, regardless of the manure fertilization. Mineral fertilization has modified soil organic carbon content.

Variety Testing

В настоящее время недостаточно известны объективные потребности растений в элементах питания, об этом свидетельствуют значительные различия между максимальными и средними значениями урожайности при испытании сортов. Существенные различия урожайности связаны с тем, что не учитываются генетические особенности сортов поглощать элементы питания из почвы и удобрений. В основном, как правило, применение удобрений рассчитывается на усредненное значение по культуре, а не под возделываемый сорт. В результате сортоиспытание без учета генетически обусловленных особенностей минерального питания приводит к тому, что агрохимически активные сорта снимаются с испытания, так как для реализации их генетического потенциала не созданы соответствующие условия минерального питания. Цель работы – оценить общую и специфическую отзывчивость сортов озимой пшеницы на применение минеральных удобрений и выделить агрохимически активные формы. Для достижения цели был заложен двухфакторный полевой опыт. Фактор А – сорта озимой пшеницы, фактор В – уровни минерального питания. В результате установлено, что наиболее агрохимически активными формами являются сорта озимой пшеницы Скипетр, Клавдия 2 и Московская 56. Сорта Безенчукская 380, Немчиновская 57 и Фотинья характеризуются как формы с меньшей агрохимической активностью. At present, the objective nutrient requirements of plants are not well known, as evidenced by the significant differences between maximum and average yields in variety trials. Significant differences in yields are due to the fact that the genetic characteristics of varieties to absorb nutrients from soil and fertilizer are not taken into account. For the most part, fertilizer application is calculated as a crop average rather than for the variety being cultivated. As a result, variety testing without taking into account genetically determined features of mineral nutrition leads to the fact that agrochemically active varieties are withdrawn from testing, because appropriate conditions of mineral nutrition are not created for realization of their genetic potential. The aim of the work is to evaluate the general and specific responsiveness of winter wheat varieties to the application of mineral fertilizers and to identify agrochemically active forms. In order to achieve the objective a two-factor field experiment was laid. Factor A - winter wheat varieties, factor B - mineral nutrition levels. As a result, it was found that the most agrochemically active forms are winter wheat varieties Skipetr, Klavdiya 2 and Moskovskaya 56. Bezenchukskaya 380, Nemchinovskaya 57 and Fotinya varieties are characterized as forms with less agrochemical activity.

The Impact

The article presents the results of studies conducted in 2004-2010 at the experimental plot in the forest-steppe Volga region. The research investigated the impact of traditional (average) and differentiated use of mineral fertilizers in the field crop rotation (winter wheat (reconnaissance sowing) – spring wheat ‒ annual grass – spring barley – bare fallow– winter wheat – spring wheat) on the change of agrochemical properties of leached chernozem. It was established that the six-year use of fertilizers contributed to the improvement of the main indicators of top soil fertility regardless of application technology. On average, in 15 sectors (plots) of each variant, the content of mobile phosphorus per rotation of crop rotation increased with differentiated fertilization by 15.9%, potassium – by 15%, and in the traditional one – by 4.8 and 16.7% respectively, (control of 100.8 and 116.2 mg/kg of soil, respectively). In sectors where no fertilizer was applied, the content of mobile elements decreased by 2-7%. The nitrogen content in the soil directly depended on the timing of sampling and the amount of moisture in the soil, so it was difficult to track its change. The difference in the accumulation of mineral nitrogen between the technologies of fertilizer application was not observed. For organic matter in all variants of the experience over the years of research there was a decrease in the indicator. This was more noticeable in the control, where the value decreased by 2.7%. Here, the value of soil acidity increased by 0.12 units and became 4.7. In variants with fertilizers soil acidity remained the same (4.6-4.7). In general, the differentiated use of mineral fertilizers did not have a negative influence on the agrochemical composition of leached chernozem. There was a gradual equalization of soil fertility due to the residual amounts of phosphorus and potassium on low-fertile plots and some reduction of mobile elements in zones with high content.

Research on the effectiveness biomodified mineral fertilizers were carried out on the basis of Ulyanovsk SRIA – SamSC RAS branch during the rotation grain fallow five fields crop rotation: pure steam – winter wheat – spring wheat – barley – oats in 2013-2018. The field experiment scheme included options (except control): with the introduction of biologics BisolbiFit (introduction with seeds that were treated before sowing), azofoski N15P15K15, in pure form, modified with biopreparation azofoski in the same dose N15P15K15, half a dose of modified azofoski (N7, 5 P7, 5 K7, 5). The effectiveness of fertilizers and biopreparations in crop cultivation was studied on three backgrounds: natural (control), ammonium nitrate at a dose of 40 kg ai/ha (NH4NO3), and modified ammonium nitrate at a dose of 20 kg DW/ha. It was established that modification of azofoski with Bisolbifit biopreparation can significantly increase the coefficients of use of elements from it by plants. The latter allows to reduce the dose of fertilizer, without reducing the productivity of cultivated crops, twice. Long-term cultivation of crops using only mineral fertilizers and biological products led to a relative decrease in the humus content in the soil and its acidification. For 6 years, the content of humus in the arable layer of leached chernozem decreased by 0.12 %, and the acidity of the soil solution increased by 0.5 pHKCI units. In the conditions of the Volga forest-steppe, when cultivated on chernozems, the highest-yielding winter wheat is (up to 4.00 t / ha or more, in our experiments 3.88-4.80 t / ha). The average yield of spring wheat was 2.68-3.31 t / ha, spring barley 2.67-3.21 t / ha, oats 2.15-2.71 t / ha. The highest productivity of crop rotation was observed against a background with modified ammonium nitrate at a dose of 20 kg ai/ha (½NH4NO3) when applying modified azofoski (N15P15K15). Grain harvest for 2013-2018 in this variant was 13.36 t / ha, exceeding the control variant on this background by 1.31 t / ha.
