One of the main tasks of organic production of agricultural products is to reduce the load on agroecosystems while simultaneously obtaining a yield indicator of high consumer quality, as with intensive production technologies, and this can be attained only through the fuller use of the biological potential of a crop, species, variety. In the production of agricultural products using biologized machine technologies, they interact with the environment: the atmosphere, hydrosphere and soil. The research is aimed to the creation of adaptive biologized machine technologies that ensure the efficient use of natural resources in the production of agricultural products with a minimum impact on the environment. The research object is the potato agrocenosis in the crop rotation of tilled and field crops. The crop rotation includes potatoes, beets, perennial legumes and cereals. In the experiment, potatoes of the Udacha variety (superelite), zoned for the Leningrad region, were cultivated. Particular attention was paid to the assessment of possible environmental risks in the implementation of the selected technological solutions for growing potatoes, as well as the fight against weeds, since the use of synthetic herbicides, fungicides, insecticides, etc. radically contradicts GOST 33980 - 2016 “Organic products. Rules for production, processing, labeling and sale”.

Purpose. The objective of the article is to investigate theoretically the possibility of harmonization of ecological and economic aspects of functioning of organic agricultural products production models under natural and climatic conditions of crop enterprises of Polissia zone in the Region of Chernihiv. Methodology / approach. The study was conducted at the Institute of Agricultural Microbiology and Agro-Industrial Manufacture of the National Academy of Agrarian Sciences of Ukraine during 2011–2020. The analysis of ecological and economic efficiency of organic crop rotations was made based on the results of the proprietary research on the example of generalization of predicted results of the developed standard models of organic crop rotations at crop enterprises of Polissia zone. Main methods: modelling (development, in particular, of standard models of crop rotations, modelling of the size of fertilizer potential over time by years); predicting (prediction of receipt and expenditure of nutrients, organic matter), balance (calculation of balances of humus and key nutrients), calculation and design (calculation of the basic parameters of economic efficiency); abstract and logical (formulation of the provisions of the article based on the analysis of studies of other authors, drawing conclusions based on the results of studies conducted). Results. Developed typical crop rotation models are characterized by positive predictive humus balances and acceptable key nutrient balances (NPK). With the implementation of ‘organic’ prices for agricultural products, most crops achieve an acceptable level of profitability. However, in order to achieve a competitive level of profitability of organic production, it must be provided with an appropriate economic mechanism of its functioning, in particular higher prices compared to traditional agricultural products, etc. Harmonization of economic and ecological aspects in simulated crop rotations is achieved primarily by selecting crops with high yields, which are mainly characterized by insufficient or low level of ecological efficiency, and crops with high or medium ecological efficiency, which having insufficient or low economic efficiency, compensate mostly negative ecological consequences of growing crops with high economic efficiency. This is accompanied by achievement of the ecological balance of agrocenoses and an acceptable level of economic efficiency of organic models. The practical aspect of the activities of specific farms in relation to the choice of the appropriate model of organic management should take into account not only considerations of ecological and economic efficiency, but also the level of resource provision within these limits. Originality / scientific novelty. The possibility of harmonization of economic and ecological aspects and achievement of their acceptable level in crop rotations of organic agriculture for crop enterprises has been theoretically substantiated. For the first time, the methodological approach developed by the authors on the distribution of costs for the production and application of organic fertilizers between crops during crop rotation in proportion to the duration and amount of fertilization was implemented. Practical value / implications. Typical models of crop rotations of organic farming for crop enterprises in Polissia were developed. Methods of choosing a certain model were proposed both according to the criteria of ecological and economic efficiency, and taking into account the organizational and economic capabilities and resource provision of a particular business entity.

Abstract As global water resources are decreasing and the demand for it is constantly increasing, the problem of proper water management is becoming more pressing. Poland is one of the largest producers of vegetables in Europe, including carrots, with significant exports. However its freshwater resources are relatively small. The paper presents the results of research on the water footprint (WF) life cycle assessment (LCA) in conventional and organic carrot production. The methodology of calculating WF was used in accordance with PN-EN ISO 14046. It was found, e.g., that the water scarcity index (WSI) for organic production of carrot (WSI = 1.9 m3∙ha-1) is over five times lower, as compared to conventional production (WSI = 10.4 m3∙ha-1). In the case of conventional production, the fertilization process (67.0% - 67.7%) has the greatest impact on the shaping of WF in the individual impact categories, i.e. Human Health, Ecosystem Quality and resources. In organic production, the WF-shaping factor is carrot harvesting (41.9% - 43.1%). The research can be used to develop pro-ecological carrot production technologies, as well as to shape sustainable development plans in agricultural areas. It can also be used to outline policy directions regarding foreign trade in water-consuming agricultural products.

The expediency of fusarium resistant lupines usage in organic farming for improving soil fertility and producing high protein feed for livestock is justified in this article. Organic production excludes the use of mineral fertilizers and pesticides. In these circumstances, increases the value of cultures that positively affect the fertility of soils and their phytosanitary status. These crops include annual fodder lupine (yellow, white and angustifolia), especially varieties that are resistant to disease. Having the highest nitrogen-fixing ability among annual legume crops, lupins, depending on the type and conditions of cultivation, can accumulate from 80 to 300 kg/ha of environmentally pure symbiotic nitrogen in biomass. Plowing the green mass (30-45 t/ha) is equivalent to the corresponding amount of manure or introduction of 5-7 t/ha of ammonium nitrate. 30 kg/ha of phosphorus and 50 kg/ha of potassium are entering the soil with plant remains. Therefore, lupine provides itself with nutrients and still leaves up to 150 kg/ha of nitrogen in the soil after harvesting for subsequent crops in crop rotation. In organic production, fusariosis resistant varieties of lupines are also interesting as a source of high protein feeds for livestock. They are building up to 60 t/ha of biomass, which contains more than one ton of digestible protein. In grain of the fodder varieties contains 40-52% of crude protein, 5.5-6.0% of fat, 10-12% of sugar. The characteristic of fusarium resistant varieties of lupins (yellow, white and angustifolia), created in the NSC "Institute of Agriculture NAAS" and included in the Register of Plant Varieties of Ukraine is presented in this article. These varieties are practically not affected by fusariosis under the production conditions and do not require the use of fungicides during the growing season. They can be grown in crop rotation with a return period of 2-3 years, whereas for unstable it took 6-7 years. Because of the inability to use in organic farming fungicide to prevent crop losses from anthracnose, it is necessary to use predominantly angustifolia lupine varieties, which are now more tolerant to this disease, prevent sowing of infected seeds and adhere to crop rotation. Fusarium-resistant varieties of lupins are suitable for cultivation in poucous and sown crops, and in mixtures with other crops.

<p class="sar-body"><span lang="EN-US">There are little economic data concerning the profitability of organic vegetable crops in the Southern Coastal Plain, especially in reference to sod-based rotation and tillage alternatives.  A three-year experiment was conducted at the North Florida Research and Education Center-Quincy involving a crop rotation sequence of oats and rye (winter), bush beans (spring), soybean (summer) and broccoli (fall). Bush beans and broccoli were the cash crops. This paper presents analyses of the riskiness of organic production utilizing years in bahiagrass prior to initiating the crop rotation sequence and conventional tillage (CT) versus strip tillage (ST). Methods of “Risk-rated enterprise budget” and “Analyses of Variance-Covariance Matrix (ANOVA)” were utilized for determining relative profitability, and coefficient of variation was applied for measuring riskiness of each treatment. Three years of bahiagrass prior to initiating the crop rotation sequence, in combination with conventional tillage, had the highest profitability and ranked as the least risky scenario.  The second most profitable treatment was conventional tillage with four years of bahiagrass. Focusing on strip tillage, four years of bahiagrass with strip-tillage ranked third in term of profitability.</span></p>

Organizational production of agricultural products is used to preserve the natural environment and to preserve the quality of the products. The development of organic wines in the light of 100 years and over the course of the period has become insane, as for the correct organization of it, you can preserve ecological, social, and commercial transfers. The organizational structure has become a warehouse part of the bio-economy and circular economy, which is a priority for the economic development of the European Union, the USA, Great Britain, the Great Britain, the Republic of Korea, Japan, and the United States of America. For determining the prospects and problems of organic production of agricultural products, general scientific methods were used such as publicity, systematization, analysis, and synthesis, of the scientific literature and normative documents. For an additional analysis of regulatory documents, a procedure for certifying the authorities of the United States, the European Union and Ukraine has been established. Ukraine, in turn, began to take the first steps towards organic production in the late 1990s. It was at this time that she began to grow organic grain and opened export lines for its transportation to other countries, mainly Europe. Ukraine remains a leader in the production and export of organic cereals. Export competitive advantages of national agar products are lower production costs and logistics support. Ukraine continues to increase its organic production capacity - an increasing number of operators are appearing in this sector of agricultural production. As of 2019, the share of organic production of crop products in Ukraine is 1.4% (5th place in the world in terms of growth rate of organic agriculture), which is 467.9 thousand hectares of the total area of agricultural land in 32, 7 million hectares, as well as 470 operators of organic production. The dynamics of changes in organic agricultural production in Ukraine indicates a general trend of increasing their number, but in some periods, there is a decrease due to the economic and political situation in the country and changes in legislation in this area. Ukraine has significant advantages of organic production, which include a high level of soil fertility, favorable climatic conditions, traditional orientation as an agrarian state. Also, the price of Ukrainian products is lower than the minimum price of organic products of European countries. In the organic production of crops use methods that optimize the biological activity of soils, provide a balanced supply of nutrients to plants. At the same time, there are problems in Ukraine that hinder the development of organic production. In particular, the diversity of the territory in terms of the level of pollution of environmental components, lack of practical application of innovations and modern technologies of agricultural production. The lack of state support for organic producers and state certification system (including qualified specialists for its implementation). Resolution of the Cabinet of Ministers of Ukraine of October 21, 2020, № 1032 "On approval of the Procedure for certification of organic production and / or circulation of organic products and amendments to the resolution of the Cabinet of Ministers of Ukraine of October 23, 2019, № 970" approved the stages of certification. Was made the comparison of approaches to the certification of agricultural enterprises in Ukraine shows that they meet European and American standards. However, the absence of a state certification body that certifies organic producers and accredits private certification bodies makes it impossible for state control over organic market operators and the functioning of state certification. The current certification system in Ukraine does not cover the issue of soil contamination or other components of environment, which may affect the quality and safety of organic products. In Ukraine, enterprises in various sectors of the economy use outdated technologies, which can cause soil contamination of agricultural lands, and, accordingly, affect the quality of organic products. Currently, the Laws of Ukraine and the Cabinet of Ministers do not require: the location of the organic agricultural enterprise; content of harmful substances in the soil (including the content of radionuclides and pesticide residues); content in the soil of nutrients that can ensure the production of quality agricultural products and confirm the activities of the farm aimed at maintaining soil fertility. To guarantee the quality of organic products, it is advisable in the certification procedure to consider the level of fertility and soil contamination of agricultural lands, as well as the availability of sources of environmental pollution in the location of the organic producer. Given the above, it is advisable to introduce criteria for assessing the compliance of soils with the requirements of organic production. This approach can guarantee the safety and quality of organic products. During the organization of organic production of agricultural products in Ukraine, the issues of criteria for assessing compliance with regulatory requirements, documentation to be kept by the operator of organic production, etc.

The reductionist approach to intensification of agriculture has created unanticipated economic, ecological and social consequences. Across the steppes, elimination of perennial legumes from the crop rotation and even elimination of crop rotation, large areas under black fallow, and the demise of crop and animal husbandry are draining soil fertility – and in many places loss of the soil itself. Data from long-term field experiments demonstrate the importance of perennial legumes in crop rotation for nitrogen- and water-use efficiency, accumulation of soil organic matter in deeper soil layers, and resilience in the face of drought.

Two trials were conducted from 1996 to 1999; one at Indian Head, SK, to examine the impact of tillage management on the severity of ascochyta blight of lentil, caused by Ascochyta lentis (teleomorph Didymella lentis), and a second at Saskatoon, SK, to assess the impact of crop rotation. In 1995, the blight-susceptible lentil cv. Eston was seeded across both sites and later inoculated with blight-infested lentil residue to provide a uniform level of infection. Treatments were initiated in the spring of 1996. Ascochyta blight severity was assessed on each lentil plot during the growing season. Seed quality and yield were assessed each year. A split-block design was used to minimize movement of inoculum among plots over years. In the tillage management trial at Indian Head, the main plot treatments were 0, 1, or 2 yr between lentil crops, with spring wheat as the alternate crop; the subplot treatments were zero-till vs. conventional tillage. Ascochyta blight severity was substantially higher under zero-till than under conventional tillage in the continuous lentil treatment when conditions were conducive to blight development. However, tillage management had little effect on severity when there were 2 yr between successive lentil crops. We conclude that tillage management is unlikely to have an important impact on blight severity, except in rotations with short re-cropping intervals. In the crop rotation study at Saskatoon, the main plot treatments were two rotation sequences and the subplot treatments were three crop species (canola, barley, pea) planted in 1996. Rotation 1 was seeded to cv. Eston in 1997 and barley in 1998; Rotation 2 was seeded to barley in 1997 and cv. Eston in 1998. Both rotations were seeded to cv. Eston in 1999. Also, a plot seeded continuously to cv. Eston was included at one end of each replicate block as a control. Blight was more severe in continuous lentil than in the other crop rotations, and ascochyta blight levels in 1999 were lowest where barley followed the 1996 lentil crop for both Rotation 1 and 2. However, the intervening nonhost crop had little impact on seed infection or seed yield. We conclude that at least two nonhost crops between successive lentil crops are required to substantially reduce inoculum of A. lentis following a disease outbreak.

Palmer amaranth’s ability to evolve resistance to different herbicides has been studied extensively, but there is little information about how this weed species might be evolving other life-history traits that could potentially make it more aggressive and difficult to control. We characterized growth and morphological variation among 10 Palmer amaranth populations collected in Florida and Georgia from fields with different cropping histories, ranging from continuous short-statured crops (vegetables and peanut) to tall crops (corn and cotton) and from intensive herbicide use history to organic production. Palmer amaranth populations differed in multiple traits such as fresh and dry weight, days to flowering, plant height, and leaf and canopy shape. Differences between populations for these traits ranged from 36% up to 87%. Although glyphosate-resistant (GR) populations collected from cropping systems including GR crops exhibited higher values of the aforementioned variables than glyphosate-susceptible (GS) populations, variation in traits was not explained by glyphosate resistance or distance between populations. Cropping system components such as crop rotation and crop canopy structure better explained the differences among populations. The higher growth of GR populations compared with GS populations was likely the result of multiple selection forces present in the cropping systems in which they grow rather than a pleiotropic effect of the glyphosate resistance trait. Results suggest that Palmer amaranth can evolve life-history traits increasing its growth and reproduction potential in cropping systems, which explains its rapid spread throughout the United States. Furthermore, our findings highlight the need to consider the evolutionary consequences of crop rotation structure and the use of more competitive crops, which might promote the selection of more aggressive biotypes in weed species with high genetic variability.
