The Impact

The role of macro– and micronutrients for corn plants is great. They increase the intensity of photosynthesis, participate in biological processes. The work is devoted to the development of science–based methods for increasing the yield and quality of corn. Field experiments were conducted in the northwestern zone of Azerbaijan. Test sites were laid in 4-fold repetition, in 6 versions. Used: ammonium nitrate, simple superphosphate, potassium sulfate, manure, compost of various waste products. All agricultural activities were carried out according to the developed technology. Before ploughing, the entire rate of manure, phosphorus and potassium was introduced, in early spring before tillage. As a result, it was revealed that with the introduction of 20 t/ha of compost — the yield of corn was 85.1 c/ha, i.e. an increase of 15.9 c/ha. It can be concluded that mineral fertilizers in combination with manure in the proportions chosen by the authors effectively affect not only the growth and development of plants, corn productivity also increases.

Potato Resistance

The results of a study of the effectiveness of the joint application of potato mineral and organic fertilizers are presented. The studies were carried out in 2017–2018. on the drained lands of the Tver region. Objects of research - potatoes of the Scarb variety, mineral and organic fertilizers in various doses. Organic fertilizers are products of the processing of organic raw materials based on fermentation processes - multipurpose compost (KMN) and BiGuEM. Mineral fertilizers - ammonium nitrate, double superphosphate and potassium chloride. In the work we used experimental methods - field experiments and theoretical research methods - mathematical statistics. Evaluation of the optimal fertilizer doses showed that BiHuEM organic fertilizer at a dose of 3 t / ha, when used together with mineral fertilizers at a dose equivalent to 3 t BiGuEM, provided potato resistance to late blight compared to the version where KMN was used - almost 8% in 2017 and 12% - in 2018, and compared with the option without the use of fertilizers (control) - by 61% and 23%, respectively. This combination of fertilizers provided the maximum yield (both general and marketable) in comparison with the control by 45% when calculating both types of yield in 2017, and in 2018 by 38% of the total and 53% of the commodity yield. A greater increase in potato yield was also revealed in the variant with BiGueM in comparison with the variant of using KMN - by 4.5% and 5.7% in 2017 and in 2018 by 6.1% and 10%, respectively. An increase in the quality of potatoes was noted, which is confirmed by the low content of nitrates in them, as well as by the increased content of starch, which was especially noted in 2017 - 34.3 g / kg and 15.99%, respectively.

The article assesses the relationships between the morphological properties of agrochernozems and yield of peas on the plots, experience with different methods of basic treatment (moldboard plowing at the depth of 20 - 22, 25 - 27 and 14 - 16 cm, moldboard plowing to a depth of 14 - 16 cm, combined midwater moldboard, mid-water subsurface, surface to a depth of 6 - 8 cm and zero tillage) is inherent in V.V. Dokuchaev Research Institute of Agriculture of the Central Black Earth strip, in the fall of 2014. The research was conducted in 2015 - 2016, with the application of mineral fertilizers (N60Р60К60) and unfertilized background. The highest pea yields in the fertilized as the background, and without the use of fertilizers was observed in dumping plowing and especially in the variant with deep moldboard plowing, which creates in comparison with other ways of handling the best conditions for the growth and development of peas. The lowest yield of pea was obtained with zero processing. Apparently legalistic migrational-mizelial agrochernozems the Central Chernozem zone of minimum tillage in the cultivation of peas are not effective, what is evident already in the first year after the laying of experience with different basic treatments. As shown by the results of applying multifactor analysis of variance studied the mapping properties of the soil can have the same significant impact on the yield of agricultural crops, as options for the field experiments aimed at assessing the impact of various treatments on yield.

В условиях Республики Коми в полевом стационарном опыте на дерново-подзолистой легкосуглинистой почве изучена эффективность различных доз органических и минеральных удобрений, а также совместного их применения. Исследования проводили в 1978–2019 годах на опытных полях Института агробиотехнологий ФИЦ Коми НЦ УрО РАН. Целью проводимых исследований было изучение влияния комплексного применения удобрений на продуктивность и качество кормовых культур в шестипольном севообороте. Кормовой севооборот имел следующее чередование культур: картофель, викоовсяная смесь с подсевом многолетних трав, многолетние травы 1 г.п., многолетние травы 2 г.п., викоовсяная смесь, картофель. В результате научных исследований (более 40 лет) установлено, что наиболее эффективной была органоминеральная система удобрений, особенно при внесении 80 т/га торфонавозного компоста (ТНК) и минеральных удобрений. Многолетние исследования показали, что наиболее значительные урожаи кормовых культур (в среднем за три ротации) получены при использовании 80 т/га ТНК и NPK: однолетних трав — 4,4 т/га; многолетних трав — 6,2 и картофеля — 7,1 т/га сухого вещества высокого качества. Содержание сухого вещества в клубнях картофеля в вариантах с NPK составило 18,0–18,8%, на органическом фоне — 18,4–18,9 и при комплексном применении удобрений — 17,1–17,7; в контроле — 19,6%. Количество крахмала в картофеле незначительно различалось по вариантам опыта и равнялось 12,6–13,1%. Содержание нитратов не превышало ПДК (250 мг/кг сырой массы). Количество сухого вещества в однолетних и многолетних травах изменялось незначительно и составляло 19,0–19,8 и 25,0–26,8% соответственно. Установлено, что удобрения способствовали повышению содержания сырого протеина в однолетних и многолетних травах до 13,1–15,0% (в контроле — 11,2%) и 8,8–10,6 % (в контроле — 8,1%) соответственно. The impact of various rates of organic and mineral fertilizers was analyzed in the Komi Republic on sod-podzolic soil with low loam content. The research took place at the Institute of Agricultural Biotechnology in 1978–2019. The goal was to test forage crop productivity and quality under fertilization and six-field crop rotation. Crop rotation happened as follows: potatoes, vetch-oat mixture overseeded by perennial grasses, first-year perennial grasses, second-year perennial grasses, vetch-oat mixture, potatoes. For 40 years the combination of mineral and organic fertilizers was the most effective. The highest yields for three rotations were observed under the application of 80 t ha-1 of peat-manure compost and NPK: annual grasses produced 4.4 t ha-1; perennial grasses — 6.2, and potatoes — 7.1 t ha-1 of high-quality dry matter (DM). Potato tubers accumulated 18.0–18.8% of DM under NPK application, 18.4–18.9 — under organic nutrition, 17.1–17.7 — when using complex fertilization, and 19.6% — in the control. Starch content varied within 12.6–13.1% in potatoes. Nitrate content did not exceed the maximum acceptable concentration (250 mg/kg of raw mass). DM concentrations amounted to 19.0–19.8 and 25.0–26.8% in annual and perennial grasses, respectively. Fertilization increased crude protein amount in annual and perennial grasses up to 13.1–15.0% (versus 11.2% in the control) and 8.8–10.6 % (versus 8.1%), respectively.

In order to obtain a higher level of crop yields in crop rotation, there is a need to increase the application of fertilizers and pesticides, which, in turn, creates environmental problems of soil and groundwater pollution by harmful chemical elements and compounds. The purpose of the study was to study the influence of fertilizer systems with different tillage systems on the accumulation of heavy metals and nitrates in the soil and the main products of field crops. Bookmarking and conducting field experiments were carried out in accordance with generally accepted methods of research. The maximum increase in grain yield from the use of N48Р18K18 on the shelf tillage system was – 0.25 (8.7%), grain units – 0.36 (9.9%), feed units – 0.41 (10.3%), digestible protein – 0.02 (5.0%) t/ha of crop rotation area. The use of N48Р18K18 in a differentiated tillage system increased grain yield by 0.34 (12.2%), grain units – 0.49 (13.5%), feed units – 1.12 (28.0%), digestible protein – 0.06 (13.6%) t/ha of crop rotation area. The use of N48Р18K18 in crop rotation with a shallow (mulching) tillage system gave an increase in grain yield by 0.38 (13.6%), grain units – 0.51 (14.2%), feed units – 0.57 (14.5%), digestible protein – 0.07 (15.9%) t/ha of crop rotation area. According to the results of research, the highest increases in mineral fertilizers in terms of productivity were characteristic of a shallow (mulching) background with a characteristic stricter nutrient regime. Our research has not found a significant increase in the content of heavy metals and nitrates in the main and by-products of field crops when applying mineral fertilizers, because their content in the products was within acceptable concentrations. The content of nitrates in the grain of different crops ranged from 18 to 40.4 mg/kg at a maximum concentration limit of 300 mg/kg. High culture of agriculture, improvement and development of new, more effective technologies of application of fertilizers in crop rotation and under each field crop taking into account soil and climatic conditions of the region, biological features of cultures and grades, specialization of crop rotations, etc. prevent environmental pollution. Rational use of mineral and organic fertilizers helps to increase soil fertility and is a major and indispensable factor in significantly increasing plant productivity and crop quality, maintaining an active biological and economic balance of nutrients without contamination of the environment with nitrates and heavy metals.

Intensification of horticulture in Russia involves planting of new high-density orchards with drip irrigation and fertigation as well as intensification of the exploitation of traditional orchards. This approach involves an increase in mineral fertilizer application imposing the risk of soil fertility loss. For several reasons, the use of traditional organic fertilizers like manure in orchards is currently marginal. Although bacteria-based biofertilizers cannot substitute mineral fertilizers completely, they can significantly reduce the need for mineral fertilizer application. The effect of microbial biofertilizers of the brands “Azotovit” (Azotobacter chroococcum), “Phosphatovit” (Bacillus mucilaginosus), as well as a mixture of bacteria and the fungus, “Organic” (Azotobacter chroococcum, Bacillus subtilis, Bacillus megaterium, Trichoderma harzian) was studied in two field experiments. In the experiment #1, the preparations “Azotovit” and “Phosphatovit” were delivered through a drip irrigation system in various combinations with mineral fertilizers. In experiment #2, the preparation “Organic” was also applied to the soil with irrigation water, also in combination with the mineral fertilizer. When solely applied, none of the studied preparations changed significantly the soil nutrient content and yield as compared with the variant fertilized by the mineral fertilizer at the maximum studied application rate. The combination of the microbial biofertilizer and mineral fertilizers applied at a low rate ensured the yield commensurate to that obtained under high-rate application of the mineral fertilizer.

The purpose of the article – to perform comparative analysis of the economic effectiveness of the 10 samples of organic fertilizer of pig farm, bio humus “Humivit” and mineral fertilizers (Nitroamofoska, ammonium nitrate, carbamide) on the example of oats. The study used the following methods: abstract-logical, cash-analytical, cash-equivalent, expert, monographic. The research was done in Ukraine. The results of the comparative analysis of economic effectiveness of the 10 samples of organic pig fertilizer, bio humus “Humivit” and mineral fertilizers (Nitroamofoska, ammonium nitrate, carbamide) in the example of oats on the green mass show that the use of organic fertilizers sample number 1, 2, 3, 4, 5, 6, 10 is an economically effective, while organic fertilizers of sample number 7, 8, 9 are economically inefficient. By the main indicators of economic effectiveness (coefficients of payback, conditional additional profit, level of profitability) organic fertilizers sample number 1, 2, 3, 4, 5, 6, 10 have significant competitive advantages over the studied brands of mineral fertilizers and bio humus “Humivit”. The use of organic pig fertilizers, except the sample number 8, in economic terms for the impact on potential soil fertility is more effective than bio humus “Humivit”. The most significant economic benefits for the impact on potential soil fertility are samples of organic fertilizers pig number 1, 5, 10, whose application generates the lowest cost price of humus. The element of novelty is that with using the author’s scientific and methodical approach it was conducted the estimation of economic effectiveness of the liquid organic fertilizer of pig farm for the impact on potential soil fertility.

В данной статье рассматриваются вопросы влияния биологических и минеральных удобрений на продуктивность озимой ржи на темно-серой лесной почве в условиях Рязанской области. Исследования проводились по методу расщепленных делянок: на делянках первого порядка на озимой ржи изучали эффективность минеральных и органических удобрений, а на делянках второго порядка – действие биопрепаратов. Результаты исследований показали, что наилучшим из исследованных агроэкологических приемов повышения урожайности озимой ржи является использование в качестве органического удобрения соломы люпина и инокуляции семян биопрепаратами ризоагрин или флавобактерин. Урожайность зерна озимой ржи составляет от 37,5 ц/га при использовании ризоагрина и до 38,7 ц/га – флавобактерина, в среднем за 3 года. Относительно фона прибавка составляет 6,7 и 7,9 ц/га или 21,9 и 25,5%. При данном агротехнологическом приеме прибавка получена как за счет увеличения продуктивных стеблей с 495 ш/м2 до 521 шт/м2 при обработке ризоагрином и 538 шт/м2 при обработке флавобактерином, так и за счет увеличения массы зерна в колосе (35,1 г на контроле, 37,5 г при обработке ризоагрином и 37,7 г флавобактерином). Необходимо отметить, что этот максимальный уровень урожайности в опыте был достигнут без внесения минеральных азотных удобрений. В целом наблюдается прямая корреляция между содержанием азота и урожайностью озимой ржи. Вынос основных элементов питания возрастает с увеличением урожайности. This article discusses the impact of biological and mineral fertilizers on the productivity of winter rye on dark gray forest soil in the Ryazan region. Studies were carried out by the method of split plots: on plots of the first order on winter rye studied the effectiveness of mineral and organic fertilizers, and on plots of the second order-the effect of biological products. The results of the research showed that the best of the studied agroecological methods of increasing the yield of winter rye is the use of Lupin straw as an organic fertilizer and inoculation of seeds with biologics rizoagrin or flavobacterin. The yield of winter rye grain is from 37.5 C / ha using rhizoagrin and up to 38.7 C / ha from flavobacterin, on average for 3 years. Relative to the background, the increase is 6.7 and 7.9 C / ha or 21.9 and 25.5%. With this agrotechnological method, the increase was obtained both by increasing the productive stems from 495 W / m2 to 521 PCs/m2 when treated with rizoagrin and 538 PCs/m2 when treated with flavobacterin, and by increasing the weight of grain in the ear (35.1 g on the control, 37.5 g when treated with rizoagrin and 37.7 g flavobacterin). It should be noted that this maximum level of yield in the experiment was achieved without the introduction of mineral nitrogen fertilizers. In General, there is a direct correlation between nitrogen content and winter rye yield. The removal of essential nutrients increases with increasing yields.

ABSTRACT Basil (Ocimum basilicum L.) is an annual plant that belongs to the Lamiaceae family. It is used as an aromatic and medicinal plant. Basil is grown in different regions with varying climates; the productivity and quality are influenced by both abiotic and biotic factors. This study was aimed to determine the impact of the application of different types of fertilizers on the yield and contents of some bioactive components in basil. The treatments consisted of three different types of fertilizers (mineral, organomineral, and organic) and control (without fertilization). The yield per plant and the essential oil content with fertilizer treatment were better than that in control. The highest fresh yield (450.9 g per plant) and oil content (0.94 mL 100 g-1) were recorded in basil cultivated using mineral fertilizers. Furthermore, the fresh yield (333.9 and 327.8 g per plant) and oil content (0.87 and 0.85 mL 100 g-1) were higher after the application of organic and organomineral fertilizers compared to that in the control treatment. There was no significant effect of fertilizer application on the total phenolics, total flavonoids, and antioxidant capacity. This study demonstrated a suitable practical application of organomineral fertilizers as a nutrient source in basil crop production in areas where the use of mineral and organic fertilizers is limited.

The article presents the results of research conducted during 2016-2019 on the impact of different rates of mineral fertilizers and by-products of the predecessor on the content of chemical nutrients in plants and the yield of maize hybrids in the Forest-Steppe. The aim of the research was to establish the peculiarities of nitrogen, phosphorus and potassium accumulation in maize plants in ontogenesis in relation to the yield of hybrids of early and middle-early maturity groups to optimize the mineral nutrition of the crop. The research was conducted on dark gray wooded soil using field, chemical, calculation-weight and mathematical-statistical methods. According to the stages of growth and development of BBCH, the peculiarities of the dynamics of nitrogen, phosphorus and potassium content in plants of hybrids with FAO 190 and 280 depending on the agrochemical load of growing technology are established. Varietal regularities of concentration of chemical elements in maize plants in connection with the accumulation of dry matter by crops in ontogenesis and yield were revealed. Hybrids with the corresponding genetically determined level of nitrogen, phosphorus and potassium content in plants have been identified and its influence on the realization of genotype productivity potential has been shown. The decisive role of potassium and nitrogen in the formation of the corn crop on dark gray wooded soil has been experimentally proved and confirmed on the basis of statistical and correlation analyzes. All hybrids were characterized by high tightness of correlations between yield and content in plants of nitrogen (r = 0.760–0.934) and potassium (r = 0.755–0.943) during the growing season as opposed to phosphorus, where these connections were of medium strength (r = 0.334–0.589) and only partially close (r = 0.702–0.806). According to the results of plant diagnostics of mineral nutrition of plants, the most effective growing technologies with different agrochemical loading are singled out, which ensure the yield of early and middle-early maize hybrids in agro-climatic conditions of the Forest-Steppe at 9.56–10.39 and 11.21–12.10 t/ha.
