It is determined that mathematical methods in combination with qualitative, logical methods of analysis contribute to the correct assessment of production efficiency or assessment of individual economic phenomena. It is a set of methods that turns analysis into truly scientific means of production management. It is proved that the most important universal method of research of economic activity of the enterprise is the method of modeling and construction of mathematical model of economic object. The study of economic processes in agricultural enterprises with the help of economic and mathematical modeling allows to assess the level of efficiency of the enterprise for the past period and to predict the effect of the implementation of certain management measures. Particular attention is paid to the principle of classification of economic and mathematical models on various grounds used in agricultural production during management decisions. The optimization models which make the widest group of models are considered and are intended for a choice of an optimum variant which will provide the maximum efficiency of the enterprise. Different approaches to the choice of basic parameters for building models to determine the resource potential are presented. It is revealed that during modeling it is necessary to follow the system approach, considering not only separate components and their interrelations, but also all system as a whole. It is advisable to use a system of models of parameters, characteristics, condition, and behavior in the external environment of interconnected economic processes, taking into account the complex structure of the organization, which will increase the adequacy and accuracy of results obtained in management decisions by managers of agricultural enterprises. It is established that economic-mathematical modeling allows to effectively solve specific economic problems and practical problems in the field of enterprise management in order to minimize the negative economic consequences.","PeriodicalId":268656,"journal":{"name":"Agriculture and plant sciences: theory and practice","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133343717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Establish the most productive types of medicinal and forage grasses for the formation of phyto-mixtures based on them to obtain organic feed additives for animal feed. Methods. Field, laboratory, animal testing by group method, means of variation statistics. Results. On the basis of the conducted researches the optimum terms of collecting of medicinal and forage grasses are established. According to the yield of dry mass, the most productive are milk thistle (3.6–4.2 t / ha), еchinacea purpurea (3.3–4.7 t / ha), fennel (3.0–4.0 t / ha) and the Moldavian snakehead (2.8–4.3 t / ha), and by the seed yield is coriander (0.3–1.8 t / ha). Hyssop, lofant anise, yarrow and shandra are also quite productive. During the years of research, annual wormwood, cephaloflora fragrant, cha­momile and cumin remained unclear for the production of raw materials. In addition, the height of these plants is low and they are not able to successfully control weeds, and the use of herbicides in the conditions of growing organic raw materials is impossible.

Give a comparative comprehensive assessment of the balance of phosphorus, Ca and Mg and establish a hierarchy of subordination of balances with the productivity of short-rotation crop rotations for long-term use of organo-mineral fertilizer system using by-products of crops as organic fertilizers for Central Forest-Steppe of Ukraine. Methods. The generally accepted methods of researches were applied: field, laboratory, mathematical methods, comparative-settlement. Research results. Regardless of the structure of short-rotation crop rotation, the balance of Ca and Mg was deficient, and the balance of Ca exceeded the balance of Mg by 4.88 times. The balance of Ca was 1.74 times more stable by the coefficient of variation. Between the components of the phosphorus balance and the balance of Ca revealed 62.5% of correlations of medium and strong level, between the turnover of Mg–9.14%, and between the components of the balance of Ca and Mg revealed 34.7% of paired correlation coefficients, indicating subordination balances in the sequence: Mg next Ca then R. Between the balance of Mg and Ca and performance, the relationship was at a low functional level. The ratio of Ca to Mg in the components of the balances did not exceed the optimal values: in the main products the ratio was 1.3 to 1, and the normalized interval varied from 0.9 to 1 to 1.6 to 1. The widest ratio of Ca to Mg was in by-products 2.3–3.7 to 1 with a normalized interval of 2.7–5.0 to 1. Conclusions. When expanding the ratio of the balance of Ca to Mg > 3 to 1 and when reaching the balance of Ca > 800 kg / ha, the circulation of phosphorus is blocked, which leads to a decrease in crop rotation productivity at the yield of k.o. up to 4.0-4.5 t / ha, and with the narrowing of the ratio of Ca to Mg to 2.5 to 1 and 1.5–2.0 to 1 there is an increase in productivity to 5-6 t / ha and 6.0–7.0 t/ha from 1 hectare. According to the established criterion of the ratio of Ca to Mg in the circulation of macronutrients, crop rotations can be classified according to increased soil protection capacity (Ca to Mg > 3) and crop rotations with high productivity (Ca to Mg <2). Crop rotations with a ratio of Ca to Mg 2.0-3.0 to 1 are intermediate in nature and combine soil protection properties with high productivity.","PeriodicalId":268656,"journal":{"name":"Agriculture and plant sciences: theory and practice","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129504112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The average values of the duration of the growing season in hybrids were intermediate between the indicators of the corresponding parent forms. The coefficients of variation in the parent forms were insignificant (1.1 – 1.4%); in hybrid populations they were low – from 4.9% (Line 744-14 / Ukrainka) to 9.2% (Line 741-14 / Suita).In terms of plant height, the limits of variability of hybrid offspring F2 went beyond the limits of variability of the parent components. The average values of the trait in hybrid populations significantly exceeded the corresponding indicators of the parent forms. The degree of variability in plant height of hybrid populations was significant in the combination Line 872-14 / Podolyanka-1 (the parent components differ in the type of plant growth) and was equal to 20.6% versus 3.5% and 4.9% for the corresponding parent forms.

The use of a herbicide based on D. R. prosulfuron (750 g/kg) increased this indicator to 90%.With flat-cutting loosening, the potential contamination of the upper 0–5-centimeter layer of soil, from which the bulk of weeds germinate, in the crops of the studied crop was 31.3–31.8% higher compared to plowing. Indicators of potential contamination and the rate of germination of weed seeds with this method of basic tillage caused a high level of actual weediness of winter wheat crops in a short-term crop rotation. However, systematic tillage without layer turnover ensured gradual self-cleaning of the lower part of the arable soil layer from weed seeds.The highest yield of winter wheat 6.11 t/ha of grain was obtained during plowing and the autumn period of application of the herbicide based on D.
