Agrology, 2(1), 41‒46. doi: 10.32819/2617-6106.2018.14016 Abstract. The research results of the influence of the basic soil tillage and fertilizer system on the fertility of soddy-podzolic soils and the yielding capacity of spring wheat in short-term rotation in the conditions of the Precarpathian region are presented. The research was carried out in 2016‒2018 on the fields of the farm “Fortuna” in the village Negivtsi of Kalush district of Ivano-Frankivsk region. The soil of the experimental plot is soddy-podzolic. It was established that the application of organic fertilizers obtained at the outlet of biogas plants at organic and organomineral fertilizer systems and methods of basic soil tillage positively influenced on the structurization of soddy-podzolic soils in the technology of spring wheat growing. The most agronomically valuable aggregates (0.25‒10.00 mm) were in the variant of surface soil tillage for the organomineral fertilizer system at sowing time ‒ 62.4%, or by 3.7% more compared with the control and before harvesting of the crop ‒ 61.6%, or by 3.8% more in comparison with control. In the same variant, the coefficient of soil structural properties was the highest ‒ 1.66 at sowing time and 1.60 ‒ before harvesting, or, respectively, by 0.24 and by 0.22 exceeded the index in the control. According to the organomineral system of fertilizer in the variant of surface soil tillage (discing at the depth of 8-10 cm), the soil density at the sowing time of the spring wheat in a layer of 0-10 cm was 1.16 g/cm3, in a layer 10‒20 cm ‒ 1.18 g/cm3, which is by 0.05‒0.06 g/cm3 less than in the control. The total porosity of the soil layer of 0‒10 cm at the organic system of fertilizer in the variant of the surface soil tillage (8‒10 cm) at the sowing time of spring wheat was 53.4%, for organomineral system ‒ 54.2%, which is, respectively, by 4,4% and by 5.2% more control. In the layer of soil 10‒20 cm, it was 52.8% and 53.1% and 4.1 and 4.4% respectively. Before harvesting the crop at the organomineral system of fertilizer, the total porosity in the layer of soil 0‒10 cm was 53.7%, 10‒20 cm ‒ 52.6%, which, respectively, by 5.9% and by 4.6% exceeded control indexes; for the organic fertilizer system they were, respectively, 52.3% and 51.8% and 4.5% and 3.8% respectively. The application of organomineral fertilizers obtained at the outlet of the biogas plant resulted in an increase in yields compared with control, on the average over the years of research by 1.41‒2.43 t/ha. The best yielding capacity indexes were achieved on the variant with surface soil tillage (discing at the depth of 8‒10 cm), according to the organomineral fertilizer system, the yielding capacity of spring wheat was 5.28 t/ha, or by 85.2% more relative to the control.

Agrology, 2(1), 51‒58. doi: 10.32819/2617-6106.2018.14018 Abstract. The processes of simulation yields and water consumption of the rice varieties of domestic selection Ukraine-96, Premium, Viscount with the help of the FAO AquaCrop model are described. As experimental data, we used the results of research on improvement of growing technologies of rice seeds, which were conducted during 2016–2018 years at the Institute of Rice of National Academy of Agrarian Sciences of Ukraine. The research was carried out in accordance with the common requirements of the experiment work and the technique of state strain testing of agricultural crops. The data of the climatic conditions of the South of Ukraine, biometric and structural characteristics of the varieties of culture under investigation, agrotechnics, physical soil and water indicators were introduced into the information system regarding the proposed AquaCrop algorithm and its conceptual provisions. The most optimal for water saving and the amount of biomass received among other simulation scenarios was the option of formation of biologically optimal irrigation schedule with an irrigation interval of allowable depletion 78% of RAW (readily available groundwater in the root zone) and a depth of 20 mm. The summarized results of simulation show that the most effective on the amount of accumulated biomass and yield was the Viscount variety with the values, respectively, 21.11 t/ha, 9.50 t/ha – in 2016 year and 19.20 t/ha, 8.83 t/ha – in 2017 year. Calculated by the program rate of irrigation in 2016 year 860 mm (8,600 m3/ha) was lower than the rate in 2017 year (900 mm) with the same rate of irrigation 200 m3/ha. In 2018, the highest indicators of biomass (21.99 t/ha) and crop yield (10.12 t/ha) were obtained in the variety Ukraine-96 with the irrigation rate of 880 mm. The results of our research with using FAO AquaCrop agrotechnology demonstrate this system as a progressive tool with a future perspective for planning the rice production process in crop yield simulation with the aim of comparison of existing and future perspective varieties according to their properties, creating the most optimal irrigation strategies for water saving and less pressure on environment.

In arid conditions of the Steppe zone of Ukraine for obtaining stable yields of lucerne and observance the conditions of resource-saving, it is important to know from what factors the value of the yield of lucerne depends on. According to the results of the conducted research, an agroecological model of the productivity of growing crop on irrigated lands of the Ukrainian Steppe has been formed. For the carrying out research, the method of artificial neuron networks was used. Creating an agroecological model of lucerne production using neuron networks consists of the following phases: search of data; preparation and normalization of data; choice of type of neuron network; experimental choice of network characteristics; experimental choice of parameters; obtaining an artificial neuron network for modeling the productivity of lucerne; checking of adequacy of the model; adjustment of parameters, final training. As a result of the research it was found that artificial neuron networks are fundamentally different from traditional methods of statistical data analysis. In the capacity of main elements of the system are taken: the sum of effective temperatures above +5 °С; amount of atmospheric precipitation; solar lighting duration; irrigation norms; depth of soil tillage; fertilization and plant protection. The article presents a constructed neuron network with architectural parameters. It has been established that among the significant number of natural and agrotechnical factors affecting the productivity of crops of lucerne, the greatest influence is carried out by atmospheric precipitation and, in our case, water-saving irrigation norms. Among the investigated factors there are a high degree of pair and multiple correlations. It is proved that the components of architecture contain different compositions of multilayered perceptrons, radial-basic functions, and also linear components.

In the agriculture of the Ukrainian Steppe was increased the potential weediness of chernozems in the arable soil layer of vegetative and seed reproductive organs. The soil is considered to be pure, in the arable layer of which there are less than 1 thousand/ha of roots perennial and 10 million pcs./ha of germinative seeds of annual weeds. Due to the excessive potential weediness of soil in bare fallows and in sowing of row crops during the vegetative period, it may appear on 1 m2 to 1.5‒2.0 thousand shoots of annual and 15‒30 sprouts or shoots of perennial weeds. Analysis of the state of potential weediness of soils of different pedogenesis and ecological and technogenic history showed that human interference in ecological and landscape complexes in the form of agricultural activity is accompanied by a significant increase in the reserves of weed seeds in the soil. Active soil tillage in crop rotation on the old arable lands is accompanied by accumulation in the layer of soil 0‒30 cm to 452 million pcs./ha of weed seeds. Analysis of the state of potential weediness of soils of different pedogenesis and ecological and technogenic history showed that human interference in ecological-landscape complexes in the form of agricultural activity is accompanied by a significant increase in the reserves of weed seeds in the soil. Active soil tillage in the crop rotation on the old arable lands is accompanied by accumulation in the layer of soil 0‒30 cm to 452 million pcs./ha of weed seeds. The danger of high degree of potential weediness is also increased by the fact that in each layer of a profile section of ploughland, a significant amount of seeds is retained, which in any case creates a risk of high harmfulness of weeds in connection with vertical migration. In the upper most active layer of soil 0‒10 cm concentration seed is 133 million pcs./ha. In the long fallow lands of agrotechnical dormancy the potential weediness in the upper layer of soil is 6‒7 million pcs./ha. In deeper layers are observed only residual signs of the presence of weed seeds. Consequently, the degree of potential weediness on cultivated lands is 20‒50 times higher than in zones of natural development of succession. Potential weediness is a major factor determining the degree of crop weediness, the harmfulness of weeds and the amount of crop loss.

Agrology, 2(1), 22‒26. doi: 10.32819/2617-6106.2018.14013 Abstract. The industrial enterprise for the extraction of polymetallic ores Vilnohirskyi Mining and Metallurgical Integrated Works (MMIW) has assumed the responsibility for the removal and sewage treatment of industrial and communal significance. An essential part of the total wastewater discharge enters into the Samotkan river from the largest waste dump called as Skazhena ravine. Sludge setting tank in Skazhena ravine is located on the left bank of the Samotkan river. Kamianske reservoir is a receiving water of debalance wastewater of the plant according to the current permit for special water use, issued for the Vilnohirskyi MMIW. The discharge of waste water from the storage tank into the Skazhena ravine is carried out in the sanitary protection zone of Verkhniodniprovskyi and Aulskyi water intakes. The site of the water object, which is the release of wastewater from the reservoir in the Skazhena ravine is located within the boundaries of the settlement of the city of Verkhniodniprovsk. The tail farm in the Skazhena ravine is a place of waste depository, which are formed at the enriching plant in the process of developing the Malyshevskyi deposit of polymetallic ores. The chemical composition of the Samotkan river is formed under the influence of surface run-off and groundwater run-off, a drainage inflow from the Kamianske reservoir, evaporation of water from swamps, bodies of water, and discharges from the sludge setting tanks (reservoirs) of the Vilnohirskyi MMIW. Comparison of the calculation data of complex pollution with established by means fishery maximum permissible concentrations showed that the water of the Dnipro river at the place of its sampling in the Verkhniodniprovskyi water intake was estimated as “moderately polluted”. But, taking into account the requirements for communal needs, water is characterized as “pure”. The concentration of substances in the return water does not exceed the maximum permissible concentrations in the conditions of communal use of the water object. Changing the channel of the Samotkan river, transformation of several beams into slime tanks, and dumping the quarry waters in Kamianske water storage is a challenge for urgent search of the optimal technologies for solving these problems.

Kamianske reservoir is a receiving water of debalance wastewater of the plant according to the current permit for special water use, issued for the Vilnohirskyi MMIW. The discharge of waste water from the storage tank into the Skazhena ravine is carried out in the sanitary protection zone of Verkhniodniprovskyi and Aulskyi water intakes. The site of the water object, which is the release of wastewater from the reservoir in the Skazhena ravine is located within the boundaries of the settlement of the city of Verkhniodniprovsk. The tail farm in the Skazhena ravine is a place of waste depository, which are formed at the enriching plant in the process of developing the Malyshevskyi deposit of polymetallic ores. The chemical composition of the Samotkan river is formed under the influence of surface run-off and groundwater run-off, a drainage inflow from the Kamianske reservoir, evaporation of water from swamps, bodies of water, and discharges from the sludge setting tanks (reservoirs) of the Vilnohirskyi MMIW. Comparison of the calculation data of complex pollution with established by means fishery maximum permissible concentrations showed that the water of the Dnipro river at the place of its sampling in the Verkhniodniprovskyi water intake was estimated as “moderately polluted”. But, taking into account the requirements for communal needs, water is characterized as “pure”. The concentration of substances in the return water does not exceed the maximum permissible concentrations in the conditions of communal use of the water object. Changing the channel of the Samotkan river, transformation of several beams into slime tanks, and dumping the quarry waters in Kamianske water storage is a challenge for urgent search of the optimal technologies for solving these problems.","PeriodicalId":33211,"journal":{"name":"Agrology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45693339","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}

Agrology, 2(1), 27‒30. doi: 10.32819/2617-6106.2018.14014 Abstract. The fruits of cherry belong to the category of prophylactic and therapeutic due to the balanced chemical composition: sugars, acids, tannins and coloring matters, vitamins. However, the quality of the fruits varies depending on the variety, growing zone, and especially under the influence of weather conditions. Just the weather conditions before harvesting have an influence on the fruit growing and productivity. Therefore, the purpose of the work was to establish the influence of such climatic indicators as the sum of effective temperatures of the period of vegetation and the phase of ripening, the amount of precipitation and the hydrothermal coefficient on the formation of the content of dry soluble substances and sugars in the fruits of cherry. The research was carried out on the basis of the Laboratory of the Department of Technology of Storage and processing of fruits and vegetables of Uman State University of Horticulture during 2013‒2017. As the objects of research were fruits of cherries of varieties Lotovka and Shpanka, grown in the Central region of Ukraine. In fruits were determined the content of dry soluble substances by the refractometric method and the total content of sugars by the ferricyanide method. In accordance with the results of research the weather conditions of the period of ripening of the fruit are affected on the formation of the content of dry soluble substances and sugar of fruits of cherry. It was established that the content of dry soluble substances is in the inverse average correlation dependence on the amount of precipitation for the cherry fruit of the Lotovka (‒0.76) and Shpanka (‒0.83) varieties. Between the hydrothermal coefficient and the content of dry soluble substances in both varieties was established the significant inverse correlation with the correlation coefficients ‒0.96 and ‒0.91. The regression equation is derived, whereby by means of the hydrothermal coefficients can predict the content of dry soluble substances in the fruits.
