The aim of the study is to investigate the state of humus and nutrient regime of leached chernozem under traditional and alternative systems of sugar beet fertilization. Field, laboratory and analytical methods were used during the research. The application of straw stabilized the humus content in the upper 0-30 cm layer of leached chernozem, increasing its content compared to the control without straw by 0.08-0.12%. The highest absolute content of humus in the layer of 0-30 cm was achieved by applying 5 t/ha of straw + N50 + N100P100K100 - 3.00% with an advantage to control without fertilizers by 0.13%. The combined application of mineral fertilizers and straw provided the conditions for favorable mineral nutrition of sugar beets at the beginning of the growing season and the stability of their growth and development during the growing season. The content of nitrate nitrogen in the layer of 0-30 cm of soil under the application of 5 t/ha of straw + N50 + N100P100K100 was 23.2 mg/kg, ammonium - 14.4, mobile phosphorus - 96, mobile potassium - 109 with the advantage to control without fertilizers by 5.2, 3.5, 7.0 and 12 mg/kg of soil, respectively. The study of the influence of alternative organic-mineral fertilizer systems on soil fertility parameters is the basis for the development of sustainable sugar beet fertilizer systems in the context of climate change.

A comparative analysis of the seeds ash composition of the breed Rif (Brassica napus L.) rapeseeds grown in the Lipetskaya region was held. The plants were grown in the conditions of the agroecological experiment using mineral (NPK and zeolite) and organic (hen droppings) fertilizers. 6 variants of the experiment were studied – the plants are grown without fertilizers application (the control); the mineral fertilizer (N60:P60:K60) separately and together with zeolite (5 t.ha-1); the zeolite in pure form (5 t.ha-1); hen droppings (5 t.ha-1) separately and together with zeolite (5 t.ha-1). We studied the accumulation of 9 basic elements (in mass %) contained in Brassica napus. seeds ash using the method of energy-dispersive X-ray spectroscopy. The accumulation order of the elements was determined: P ≈ K > Mg ≥ Ca > Mo > S > Zn > Mn > Fe. The proportion of P fluctuated from 10.852 to 11.855 mass %; the proportion of K – from 9.933 till 12.343 mass %. The rapeseeds contained Mg, Ca, and Mo in similar concentrations within the range of 4.0 -5.8 mass %. The combined application of zeolite with organic fertilizer ensured the accumulation of the minerals in the seeds. Correlations between the elements were established. High correlation between elements K and Mo was found (r = 0.96); P and Mg (0.86); P and Fe (r = 0.94); C and Mo (r = 0.86). The positive effect of the combined organic-mineral fertilizers with poultry farms wastes usage on the mineral elements accumulation in rapeseeds was stated. It is noted that the accumulation of P, Ca, Mo, and S in rape seeds leads to a decrease in Zn.

Water Holding

The results of a field experiment held on podzolic black heavy loam soil of the Right-Bank Forest-Steppe of Ukraine, studying the effect of various fertilization systems on the water-holding capacity of sugar beet, are presented. It was found that the change in nitrogen, phosphorus and potassium nutrition has a different effect on this indicator when closing the leaves of sugar beet plants between rows and during the harvest time. Half-dead cattle manure KRS on straw bedding aw well as mineral fertilizers, namely aqueous ammonia, ammonium nitrate, granular superphosphate, mixed potassium salt, potassium chloride, ANP fertilizer grade A and liquid complex fertilizer grade 10–34–0 were used during the experiment. Manure was applied at a dose of 40 t / ha and mineral fertilizers – N120Р120К120. Fertilizers were applied in August during fall plowing, as well as in late autumn (at the end of October) together with moldboard-free loosening of the soil to a depth of 14–16 cm and in spring –under pre-sowing cultivation. The dynamics of the intensity of water return was monitored by cut sugar beet leaves under conditions of rapid natural evaporation by weighing them every 0.5, 1 and 2 hours (according to Arland's method). It was found that the leaves of sugar beet, both with insufficient and unbalanced nitrogen nutrition, have a weak water-holding capacity during the growing season. Improving phosphorus nutrition, especially when applying liquid complex fertilizer grade 10–34–0, helps increase the water-holding capacity of sugar beet plants throughout the growing season. Replacing potassium chloride with potassium salt mixed as part of a complete mineral fertilizer significantly increases the water-holding capacity of sugar beets due to the better provision with sodium. This is particularly evident in the second half of the growing season. With the age of sugar beet plants, a distinct decrease in the intensity of water loss is observed regardless of fertilization, which can be explained by an increase in the content of bound water due to a rise of the amount of dry matter.

Purpose. Increasing the uniformity of distribution of mineral fertilizers and other bulk materials due to the stability of their feed from the body to the spreading working bodies using the top feeder. Methods. The following methods are used to achieve this aim: the method of comparing the differences between individual groups of fertilizers, the method of analyzing the properties of a new technical system, the method of functional inventiveness, and the methods of theoretical and analytical mechanics. Results. The traction body of the conveyor of the upper feed of the body fat body machine for mineral fertilizers and other bulk materials was substantiated and the relationship between the height of its scrapers and the distance between them was established, as well as the nature of the mineral fertilizer pressure on the curvilinear wall of the body. In addition, the design of the advanced body fertilizer spreader is justified, which ensures a stable flow of fertilizers from the body due to the improvement of the top feeder. Conclusions. Because of the conducted researches, the advantages of machines equipped with top feeder are found. They create the conditions for the forced feeding mineral fertilizers and other loose materials from the container to the distribution bodies, which is a prerequisite for their evenness on the surface. With this, the imperfection of known machines with the top feeder constrains their introduction into agricultural production. On this account, a more thoroughly constructed solution of the body feeder of the top feed is substantiated, in which the conveyor provides a stable supply of fertilizers from the body with reduced energy consumption during operation.

The cultivation expediency of more drought-resistant crops, in particular sorghum, millet, false flax, safflower and others, instead of sunflower in the area of the Southern Steppe of Ukraine is substantiated. This is, first of all, required by climate change both in Ukraine and in the world. Since 2004, researches of field crops were carried out in the conditions of the Educational and Scientific Practical Center of the Mykolaiv National Agrarian University. Soil phase is the southern chernozem with humus content in the 0–30 cm soil layer which consist of 2.96–3.21 %, with medium and high level of availability of mobile phosphorus and potassium and low – mobile nitrogen. Experiments with soriz (Oksamyt hybrid) were conducted during 2004–2006, millet (Tavriiske, Kostantynivske, Skhidnevarieties) in 2008–2010, grain sorghum (Stepovyi 5 hybrid) in 2014–2016, safflower dye (Lahidnyi variety) in 2017–2019. The years of research differed significantly in temperature and even more in the amount of precipitation before sowing and during the growing season of crops. However, the weather conditions were typical of the Southern Steppe zone of Ukraine. It is established that all studied drought-resistant crops respond positively to nutrition optimization – the level of yield and quality of grain or seeds increases. It was found that the soriz productivity depending on the application of fertilizers and sowing dates increased by 37.6–39.2 %, millet –by 33.3–41.6 %, grain sorghum depending on the background of nutrition and growing conditions – by 8.2–33.2 %, dye safflower – by 11.1–64.6 %. It was determined that the optimization of nutrition of cultivated crops allows to increase their resistance to adverse conditions and productivity in the case of application of low doses of the mineral fertilizers before sowing, pre-sowing treatment of seeds, and growth-regulating chemical application of plants on the main stages of the growing season. Key words: drought-resistant plants, climatic conditions, nutrition optimization, yield, crop quality, varieties, sowing dates.

O mamoeiro é umas das plantas frutíferas mais comuns em quase todos os países da América Tropical. Um dos principais problemas na cadeia produtiva da cultura de mamão é obter bom manejo do material propagativo e garantir uniformidade e qualidade de estande, sendo para isso necessária a obtenção de mudas de qualidades fisiológicas e sanitárias adequadas.  A utilização de produtos alternativos vem demonstrando efeitos significativos no desenvolvimento radicular de várias plantas, o que beneficia a formação de um pomar de maneira rápida, homogênea, permitindo assim a antecipação da colheita e maior lucratividade ao produtor. O objetivo deste trabalho foi avaliar o efeito do organomineral em diferentes doses na produção de mudas da cultura do mamoeiro da cultivar Sunrise Solo Line 72/12, em condições de ambiente protegido. O experimento foi conduzido no viveiro de mudas do Centro Universitário de Santa Fé do Sul - UNIFUNEC, Campus II. O delineamento experimental utilizado foi de blocos inteiramente casualizados, com seis tratamentos (0; 0,050; 0,100; 0,200; 0,300 e 0,400 kg tratamento de organomineral) e quatro repetições (6X4), utilizando 5 saquinhos por repetição, totalizando 120 saquinhos. Os dados biométricos analisados foram altura da planta (cm); comprimento da raiz (cm); diâmetro do caule (cm); massa úmida e seca da área foliar (g) e massa úmida e seca da raiz (g), aos 60 dias após plantio. Com base nos dados obtidos dos caracteres agronômicos analisados, conclui-se que o uso das doses 0,050; 0,100; 0,200 e 0,300 kg por tratamento de fertilizante organomineral promoveu a obtenção de mudas de mamoeiro com maior qualidade fisiológica que são imprescindíveis na formação de pomares comerciais.   REVIEW OF DIFFERENT DOSES OF ORGANIC MINERAL FERTILIZERS FOR PAPAYA SEEDLING DEVELOPMENT   ABSTRACT The papaya tree is one of the most common fruit trees in almost all Tropical American countries. One of the main issues in the papaya cultivation production chain is obtaining good management of propagative material and provide uniformity and quality for sales quality assurance, being to this end necessary to obtain physiological and sanitary appropriate seedling. The use of alternative products has demonstrated significant effects on the root development of several plants, benefiting a fast, homogeneous formation of an orchard, resulting in the anticipation of the harvest and higher profitability for the farmers. This paper aims at reviewing the organic mineral in different doses to produce papaya tree seedling from cultivar Sunrise Solo Line 72/12, in environment-protected conditions. The experiment was carried out at the Centro Universitário de Santa Fé do Sul - UNIFUNEC, Campus II greenhouse. The trial design chosen was the completely randomized blocks, with 6 treatments (0; 0,050; 0,100; 0,200; 0,300, and 0,400 kg organic mineral treatment), and four repetitions (6X4), using 5 small bags per repetition, total 120 small bags. Biometric data analyzed was the plant height (cm); root length (cm); stem diameter (cm); wet and dry mass of the leaf area (g), and wet and dry mass of the root area (g), 60 days after planting. Based on the data obtained from agronomic characters analyzed, it was concluded that the use of 0,050; 0,100; 0,200, and 0,300 kg doses per treatment with organic mineral fertilizer provided papaya tree seedling with higher physiological quality which are vital for the commercial formation of orchards.   Keywords: Carica papaya L.

The studies were carried out under the conditions of a microfield experiment on typical chernozem (Belgorod region) with two soils (pH 5.0 and 6.5) with the addition of urea (enriched in 15N, 17.1 at. %) And effluents from a pig-breeding complex (PSC) at doses of 6 and 12 g N/m2 (against the background of phosphate and potash fertilizers, P6K6). The largest amount of nitrogen was consumed by sugar beets with the combined introduction of CCA and urea (25.8 g N/m2). When the soil was acidified to pHsalt 5.0, the consumption of nitrogen in mineral fertilizers decreased by 15-18%, soil ni-trogen – by 21-52%, and waste nitrogen – by 16%. At the same time, the immobilization of nitrogen in the fertilizer decreased by 13-18%, and the loss of gaseous nitrogen compounds increased by 47-108%. The effluent from the pig-breeding complex increased the immobilization of nitrogen in mineral fertilizers (by 38-46%) and reduced gaseous nitrogen losses (by 22-44%). The highest stability and productivity (root crop yield 1654 g/m2, tops yield 239 g/m2) was exhibited by agrophytocenosis on soil with pH 6.5 with the combined application of CCA and urea. When the soil solution was acid-ified to pH 5.0, the yield of beet root crops decreased by 30% and the yield of tops – by 24%. On soil with pH 5.0, fertilizers increased the sugar content in root crops by 0.2-1.3%, on soil with pH 6.5, they decreased by 1.3-2.0%.

Through the period of 1977–2018, studies were conducted on three experimental fields of the Samara State Agricultural Academy with the purpose of studying the influence of the basic elements of the farming system on the weediness and the yield of winter wheat. Experimental schemes included the following options: the type of fallow in the crop rotation (black, seeded and green-manured), fertilizer systems (organic-mineral recommended, organic-mineral intensive and organic) and various methods and depths of soil tillage of fallow lands. Observations and surveys were carried out according to generally accepted methods. The soil of the plots was ordinary chernozem and typical medium-thick loamy chernozem (humus content was from 6.0 to 8.3 %, mobile phosphorus was from 90 to 155 mg/kg, exchange potassium was from 129 to 190 mg/kg, pHsalt was from 6.3 to 6.8). Replacing black fallow with seeded or green-manured fallow increased the weediness of crops 1.4–1.6 times and reduces the yield of winter wheat by 0.29–1.03 t/ha. Organic fertilizer systems significantly changed the weed species compositions and contributed to an increase in the number of perennials by a factor of 3.0, and their masses by a factor of 1.3–1.4 in comparison with organic-mineral fertilizer system. Organic-mineral fertilizer systems did not have a significant effect on the yield of winter wheat. The organic fertilizer system led to a slight (0.26–0.31 t/ha) grain shortage compared with organic-mineral. The methods and depths of soil tillage did not have a practically significant effect on the weediness and yield of winter wheat.

Топинамбур ценная культура, используемая в различных отраслях. Цель исследований: оценка адаптивности сортов топинамбура Файз-Барака и Мужиза к условиям жаркого сухого климата и засоленных почв, а также разработка важнейших элементов технологии для получения урожая в экстремальных условиях. Климатические условия характеризуются резко континентальным климатом, очень жарким летом и холодной зимой. В Кегейлинском районе, где проводились испытания, незначительное количество осадков в весенний период (510 мм), их отсутствие в летние месяцы и постоянный ветер способствуют низкой относительной влажности воздуха (1128) и засушливости. В летний период температура днем повышается до 4043 C, что вызывает стресс у всех произрастающих культур. Почвы участка, где проводили исследования-лугово-аллювиальные, легкосуглинистые, слабозасоленные, тип засоления-хлоридно-сульфатный. В пахотном горизонте содержание гумуса составляет 0,871,03, валового азота 0,100,12, фосфора 0,230,28, калия 2,52,7 мг/кг, а обменного калия 197305 мг/кг почвы. В период вегетации соли постепенно поднимаются в корнеобитаемый слой и на поверхность почвы, что отрицательно влияет на рост и развитие культур. Агротехнические мероприятия включали промывку почвы от солей в зимний период водой (35004000 м3/га), вспашку, боронование, нарезку борозд, две культивации в период вегетации, внесение минеральных удобрений общей нормой N100P150K100 (д.в.), 34 полива с нормой 600650 м3/га. Факторы и варианты опыта: два сорта топинамбура при четырех сроках посадки клубней, трех схемах посадки, трех фракциях массы клубня и трех вариантах глубины посадки. Каждый опыт закладывали в четырехкратной повторности рендомизированным способом. Площадь делянки каждого варианта опыта составляла по 55 м2. Использовали стандартные методики. При оптимальном сроке посадки клубней 5 апреля, клубнями массой 4060 г на глубину 910 см по схеме 7040 см обеспечивается наибольшая урожайность у сорта Файз-Барака (2,79 кг/м2) и Мужиза (3,02 кг/м2).Jerusalem artichoke is a valuable crop used in various branches of industry. The goal of the research is to assess the adaptability of Jerusalem artichoke Fayz-Baraka and Muzhiz cultivars to the conditions of hot dry climate and saline soils, as well as to develop the most important elements of the technology for obtaining a yield in extreme conditions. Climate conditions are characterized by a sharply continental climate, very hot summers and cold winters. In The Kegeyli region where the tests were conducted, the low amount of precipitation in the spring (510 mm), their absence in the summer months and constant wind contribute to low relative humidity (1128) and dryness. In summer, the daytime temperature rises to 4043 C, which causes stress for all growing crops. The soils of the area where the research was carried out are meadow-alluvial, light-loamy, slightly saline, and the type of salinity is chloride-sulfate. In the arable horizon, the humus content is 0.871.03, gross nitrogen 0.100.12, phosphorus 0.230.28, potassium 2.52.7 mg/kg, and exchange potassium 197305 mg/kg of soil. During the growing season, the salt gradually rises in the root layer and on the soil surface, which negatively affects the growth and development of crops. Agrotechnical measures included washing the soil from salts in winter with water (35004000 m3/ha), plowing, harrowing, cutting furrows, two cultivations during the growing season, applying mineral fertilizers with a General norm of N100P150K100 (act. subst.), 34 watering with a norm of 600650 m3/ha. Factors and experience options: two varieties of Jerusalem artichoke with four terms of planting tubers, three planting schemes, three fractions of the mass of the tuber and three options for planting depth. Each experiment was laid out in a four-fold repetition in a rendomized way. The plot area of each variant of the experiment was 55 m2. We used standard methods. The optimal term for tubers planting on April 5, planting tubers weighing 4060 g to a depth of 910 cm according to the 70x40 cm scheme provide the highest yields for the variety Fayz Baraka (2.79 kg/m2) and Mujiza (3.02 kg/m2).
