To reduce the accumulation of toxic substances in tubers in 2014–2016 the author studied biological methods of fertilizers application and plant protection in black earth forest-steppe region under the conditions of high-intensity potato cultivation technology along with drip irrigation. The introduction describes the importance of potato in the diet of population and lists the environmental issues that arise as a result of enhanced using of chemicals during crop cultivation. The doses of mineral fertilizers in experiments were introduced separately and in combination with a bioameliorant: 1) without fertilizers (control site); 2) N60P90K60; 3) N90P135K90; 4) N120P180K120; 5) biological ameliorant – white mustard, post-harvest green manure; 6) bioameliorant + N60P90K60; 7) bioameliorant + N90P135K90; 8) bioameliorant + N120P180K120. Chemical insecticide Aktara and biological preparations Fitoverm, Akarin were used to protect potatoes against Colorado potato beetles. Insecto-fungicide Celest was used to treat seed tubers against fungal diseases. During growing season the author used fungicides Profit Gold, Ridomil Gold against fungal diseases, against weeds – Zenkor and Remus. High yield of potato environmentally friendly considering nitrates was obtained by means of simultaneous application of N90P135K90 and white mustard green mass. Tuber yield was 40.4 tonnes per hectare compared to 22.7 tonnes per hectare on the control site, and nitrate content was 111.3 mg while maximum permissible concentration (MPC) is 250 mg/kg. According to MPC established in the Russian Federation, for childrenʼs and dietary nutrition fertilizer dose should not exceed N60P90K60 in combination with a bioameliorant and a biological plant protection system. Safety interval (period between plant treatment and harvesting) for chemical insecticides is 35–40 days; fungicides – 20 days; herbicides (depending on their type) – 55–70 days. The production of ecologically clean potato according to EU standards was achieved only by means of using post-harvest green manure as a fertilizer, applying biological insecticides and Celest preparation within the framework of protecting plants against pests and diseases.

The Impact

Aim. To study the changes in the content and stock of organic substances as well as the reaction of the soil en- vironment depending on the impact of different types of fertilization of green-manured fallows. Methods. Field studies were conducted on podzolized heavy loamy chernozem, on loess, in conditions of Right-Bank Forest- Steppe of Ukraine. Experimental design included: sweet clover with the seeding rate of 20 kg/ha, white mustard – 20, oilseed radish – 20, spring vetch – 150, and buckwheat – 150 kg/ha with the following fertilization variants: no fertilizers – control; N 40 ; P 40 K 40 ; N 40 K 40 ; N 40 P 40 ; N 40 P 40 K 40 ; N 80 P 40 K 40 . The content of total carbon and nitrogen were defi ned using Anstett’s method, modifi ed by Ponomariova and Nikolaeva; the content of total humus in the soil prior to sowing winter wheat (the impact of green manure for a year) – according to DSTU 4289:2004, pH of the water extract – according to DSTU ISO 10390:2007. Results. Nitrogen-carbon ratio was in the range from 11.1 to 11.8 in the biomass of leguminous crops and from 18.8 to 20.7 – in root remains, and its highest value was observed in root remains of Brassicaceae crops – from 28.8 to 34.5 depending on doses and types of mineral fertilizers. Compared to bare fallow, green manure fertilization promotes humus preservation in the soil. The de- crease in the level of humus intension of the soil by 0.01–0.04 % was registered both in the surface and subsurface layers in conditions of bare fallow compared to green-manured fallow. 1.67 t/ha of humus is mineralized in the soil of bare fallow. The transformation of green manure biomass allows accumulating 1.15–2.05 t/ha of humus depending on doses and types of mineral fertilizers. When the Cruciferae family (white mustard and oilseed rad- ish) are used as green manure, the isohumus index is 1.52–1.55, 1.67–1.69 – for the Leguminosae (annual sweet clover and spring vetch), and 1.52–1.60 – for buckwheat, depending on fertilization. The humifi cation coeffi cient for vegetative biomass of oilseed radish is 0.023, for spring vetch – 0.027, for buckwheat – 0.033, for white mustard – 0.035, and for annual sweet clover – 0.036. The administration of different doses and types of mineral fertilizers conditions the decrease in the coeffi cient of green manure fertilization. Conclusions. The application of green manure both with and without fertilizers compared to bare fallow promotes the preservation of humus content in the soil. The transfer of calcium from lower layers to the arable soil layer, performed by the plant root system in green-manured fallow, decreases active acidity of the soil.

The Right

The research results of the influence of fertilizer systems on the productivity of spring barley in the Right-bank Forest Steppe were presented. Traditionally fertilized backgrounds were studied: mineral, organic and organomineral (with half fertilizer rates of previous backgrounds), and the alternative to organic matter was cereal straw and biomass of green manure crops. The best backgrounds and optimal fertilizer systems for high level of grain yield were determined. The main factors that formed the productive plant density of spring barley were the rates and types of fertilizers. The improving of plant nutrition due to using of organic and mineral fertilizers led to an increase in the productive plant density in the agrocenosis and the competitiveness of plants, the reducing of weed infestation. Depending on the type of fertilizer, the grain yield of spring barley changed. Based on the research results, it was found that the combination of traditional fertilization with the application of alternative types of organic matter increased the grain yield of barley spring compared to the control variant on mineral background within 1.61–2.04 t/ha, organic – 1.69–2.14 t/ha, organomineral – 1.79–2.19 t/ha. At the same time, the yield indicators had a range: 4.86–5.29 t/ha on the mineral, 4.94–5.39 t/ha – organic and 5.04–5.44 t/ha organomineral background. The highest yield of spring barley was provided by a combined fertilizer system with half norms both mineral fertilizer and manure against the background of the afteraction of predecessor straw with compensatory dose of N10/t and green manure biomass of white mustard as organic fertilizer, and equaled of 5.44 t/ha (yield gain was 2.19 t/ha compared to control). The optimal fertilizer systems to increase of spring barley yield in conditions of the Right Bank Forest Steppe are combined mineral, organic and organomineral fertilizer systems, which include the use of traditional fertilizers: the action of mineral fertilizers and the afteraction of manure, as well as alternative fertilizers – the straw of predecessor with a compensatory dose of N10/t in combination with the white mustard biomass. Keywords: spring barley, predecessor by-products, mineral fertilizers, yield, fertilizer systems, grain quality.

If a farmer has nematode problems or has too many weeds or fungal attacks a simple solution is to spread some mustard on them. Agricultural Research Service and university scientists are experimenting with mustards as an alternative to fighting crop pests chemically. The system biofumigates pests with stands of white mustard, brown mustard, and rapeseed.. Biofumigation refers to natural substances plants release while decomposing that make surrounding soils toxic to some weeds, nematodes, and fungi. The experiments, in Washington State, dovetail with increasing grower interest in mustard crops for pest control and as "green manure" meaning it can be disked into soil to improve tilth, organic matter, aeration, and water filtration. Despite such benefits, there is still much to learn about how mustards control pests and under what conditions they work best.

The Impact

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.

The aim of this work is to develop an innovative technology for the cultivation of Myrtillocactus geometrizans, introducing the use of Effective microorganisms and at the same time, limiting the use of mineral fertilizers, plant protection products and improving the physico-chemical and organoleptic characteristics of garambullos for consumption and processing. The trial showed a significant improvement in the agronomic parameters analysed on Myrtillocactus geometrizans plants treated with Effective microorganisms. In particular, there was an increase in plant height and circumference, vegetative and root weight, number of flowers and fruits, number and length of thornes in plants treated with microorganisms. In addition, the use of EM microorganisms showed a significant increase in total betalains, ascorbic acid, phenols and total flavonoids in garambullos. It was important to underline how the use of Effective microorganisms guaranteed, despite the reduction of irrigation and fertilisation by 50% in the growing medium, the same results in terms of agronomic parameters and fruit production and quality as the control with irrigation and fertilisation under optimal conditions. The application of Effective microorganisms in agricultural processing can therefore guarantee higher production standards, with a possible reduction in costs fertilizer and water. Particularly for those farms that want to focus on the production of ornamental and fruit cacti. Fruits obtained from growing plants treated with Effective microorganisms have a high antioxidant and nutraceutical potential, which is very important especially in this age where food is also a medicine.

The Government

The demand for organic food is a prerequisite for the formation and development of organic agriculture, and the task of promoting it on domestic and foreign markets is among the priority ones. A serious problem in the sale of this category of goods to the domestic food markets of the country is the distrust of potential consumers. It is possible to solve this problem through certification and the use of a well-known brand. Certification of manufacturers of environmentally friendly products is a rather complicated and expensive procedure, therefore it is not available for most agricultural producers in the Saratov region. However, basing on the fact that today the task of developing the organic agriculture industry is set at the level of the government of the country, it is possible to solve this problem with the support of the state. The article examines the enterprises of the Saratov region of various legal forms, which do not use fertilizers and chemical means of crop protection in the production of crop production. Using the example of agricultural organizations and farms in the region, a mechanism for subsidizing certification of the most promising producers of organic wheat (winter and spring) is proposed, which includes the allocation of targeted subsidies for its implementation. As a criterion for the selection of applicants for this type of state support, as well as the distribution of budgetary resources between them, it is proposed to use the average indicator (potential) of the annual volume of organic production in the work. As a result, direct participants in certification subsidies were selected from the compiled sample of the studied enterprises that do not use chemical plant protection products and mineral fertilizers and the total annual volume of their marketable wheat was determined. The author determined the maximum cost of quality confirmation procedures for one enterprise, taking into account the increasing coefficients per one day of inspection, and also established the largest amount of budgetary resources that may be spent on the implementation of the proposed measure. In order to evaluate the effectiveness of the proposed certification subsidy mechanism, the author developed formulas for determining the selling price of products in the promising organic segment, taking into account its increase by the level of premium premiums.

In the modern conditions of agricultural development, the use of microbiological preparations as an alternative to mineral fertilizers and chemical plant protection products is gaining wide interest and practical significance. Soil microorganisms have the ability to interact with the root system of plants, optimize mineral nutrition, synthesize growth hormones and antimicrobial compounds that inhibit the development of phytopathogenic fungi and bacteria and have a stimulating effect on the growth and development of cultivated crops, increasing their resistance to phytopathogens and stress. The search for environmentally friendly technologies, the use of enzymes and active metabolites of bacterial origin, or the use of bacterial strains that promote plant growth is a promising direction. The effect of culture fluid of Bacillus ginsengihumi and Pantoea brenneri on the average length of the plant stem was studied. When processing wheat seeds of P. brenner AS3, the length of the first leaf increased by 50%, and B. ginsengihumi M2.11 by 25%.

Plant Protection System

The purpose of the research was to study the effect of mineral fertilizers and plant protection system on the vegetation index NDVI and its seasonal dynamics in agrocenoses of spring barley with overseeding of perennial grasses in the North-West of Russia. The data obtained indicate that against the background of the deficiency of the main elements of mineral nutrition in the second half of the growing season of spring barley, a significant phytomass of perennial grasses is formed in the crop, which account for 36.7%. This leads to a smaller decrease in the NDVI index (by 0.06) than in the fertilized variants (0.20). The value of NDVI index reflects not only the state of cultivated plants and weed infestation of crops, but also the level of development of crops, growing under vegetation. The influence of mineral nutrition developed during the period of maximum values of the index, which were recorded 6-8 weeks from the sowing date and 26-30 weeks from the beginning of the year. Under the influence of average doses of fertilizers, the NDVI index increased by 0.09...0.2 (on average 0.13), under the influence of high doses – by 0.13...0.26 (on average 0.18). The influence of plant protection system was expressed by a decrease in the phytomass of weeds (by 49.4...68.9%), at the same time the mass of spring barley and perennial grasses increased (by 1.7...18.5% and by 11.7...43.5% respectively). Carrying out the whole complex of protective measures led to a decrease in the NDVI index values by 0.01...0.06, depending on the phytosanitary situation in the agrocenosis. The most reliable forecast of the yield of spring barley can be implemented in the period from 5 to 7 weeks from the beginning of the emergence of barley shoots, especially against the background of the use of plant protection products that eliminate the influence of harmful organisms on the formation of the crop and the optical properties of crops

The experimental studies were carried out on the fields of the Sumy NAU Training Research and Production Complex (TRPC) during 2016–2018.The soil of the experimental plot is typical deep-medium humus, large-dusty and medium-loam black soil on forest trees. The subject of the research was a white mustard variety of Oslava created at the Institute of Feed and Agriculture of the Podillya NAASU, entered in the Register of varieties suitable for cultivation in Ukraine in 2010. The aim of the research is to optimize the nutrition of the white mustard variety of Oslava through the complex application of mineral fertilizers and foliar fertilization under the conditions of the northeastern forest-steppe of Ukraine. The analysis of weather conditions, in particular the hydrothermal coefficient of Selyaninov (HTC), established that 2016 season was wet (HTC = 1.60), 2017 and 2018 were dry (HTC = 0.59 and 0.46). During the research, the cultivation technology was generally accepted in the experimental area, except for the elements studied. The results of the three-year study on the influence of foliar fertilizing under different mineral nutrition backgrounds on the yield of the white mustard variety Oslava are presented. It was found that the application of mineral fertilizers and complex fertilizers for the foliar feeding had a positive effect on the morphometric parameters of the white mustard, in particular, increased the plant height and the number of branches of the first order. The use of mineral fertilizers at the rate of N30P30K30 provided an increase in the yield by 0.34 t/ha, N60P60K60 – by 0.55 t/ha, N90P90K90 – by 0.61 t/ha on an average compared to the control. Therefore, for the maximum yield (2.14–2.21 t/ha) with a mass of 1000 seeds (5.39–5.54 g) of the white mustard under the conditions of the Northeastern Forest-Steppe of Ukraine, foliar fertilizing of Vuxal boron (3.0 l/ha) + Vuxal bioaminoplant 3.0 l/ha) and Spectrum B + Mo (2.0 l/ha) + Spectrum Ascorist (3.0 l/ha) should be applied on the background of N60-90P60-90K60-90, what provided an increase in the yield compared to the control of 0.58-0.65 t/ha.
