The fertilizer system is one of the most expensive elements of crop production technology, including corn. In today's difficult conditions, there is an acute shortage and rising prices for various types of energy resources, including mineral fertilizers. The variability of climatic and weather conditions and the high cost of mineral fertilizers leads to the search for alternative approaches to optimize existing and develop new technological methods of cultivation. This article evaluates and identifies the main aspects of optimizing the corn fertilization system through the use of modern biofertilizer Grandfix in combination with mineral fertilizers in full and with a reduction in their rate by 30%. The urgency and production necessity of such technological solutions and the search for optimal options for maximizing the yield potential of modern maize hybrids are determined given the importance of this crop for the formation of Ukraine's export potential. The efficiency of application of soil biofertilizer Graunfix produced by BTU-Center, which is recommended for pre-sowing cultivation, in combination with full and reduced rate of mineral fertilizers at different rates of seed sowing. It was established that with the application of soil biofertilizer Groundfix at the rate of 6 l / ha, the increase in yield was, respectively, 5.4-7.1%, or 0.82-0.97 t / ha. The maximum yield in the experiment was 18.31 t / ha and was recorded in the hybrid P8834 on the variant with a seeding rate of 75 thousand / ha. In addition, it should be noted that in the options with a decrease in the rate of mineral fertilizers by 30% N80P40K40 (70%) + Graunfix 6 l / ha received a fairly high yield of 15.07-16.53 t / ha in the hybrid P8834, 14.02 -14.96 t / ha in P9074 and 12.46-13.56 in P9241, which has a high positive effect from an economic point of view.
肥料系统是作物生产技术中最昂贵的元素之一,包括玉米。在今天的困难条件下,包括矿物肥料在内的各种能源资源严重短缺,价格不断上涨。气候和天气条件的变化以及矿物肥料的高成本导致寻找替代方法来优化现有的和开发新的栽培技术方法。本文评价和确定了通过充分使用现代生物肥料Grandfix与矿物肥料组合优化玉米施肥系统的主要方面,并将其减少30%。鉴于现代玉米杂交作物对乌克兰出口潜力的重要性,确定了这种技术解决办法的紧迫性和生产必要性,并确定了寻求最大限度提高现代玉米杂交作物产量潜力的最佳选择。btu中心生产的土壤生物肥料grunfix在播前栽培中推荐使用,在不同播种速率下,与矿质肥的满施和减施量相结合的施用效率。结果表明,施用土壤生物肥6 l / ha时,增产幅度分别为5.4% ~ 7.1%和0.82 ~ 0.97 t / ha。试验最高产量为18.31 t / ha,记录在该变异的杂交品种P8834上,播种量为7.5万t / ha。此外,需要指出的是,在矿物肥施用量减少30%的方案中,N80P40K40 (70%) + grunfix 6 l / ha的杂交组合P8834、P9074和P9241分别获得了15.07-16.53 t / ha、14.02 -14.96 t / ha和12.46-13.56 t / ha的较高产量,从经济角度看具有较高的正效应。

Ukraine is a powerful participant in the world grain market, and grain stocks of domestic farmers are an integral part of global food security. Among cereals in the agro-industrial production of barley is a leading place in the structure of sown areas, it is second only to wheat. However, when conducting a comparative analysis of the yield of barley in Ukraine and other world producers, it should be noted that the average yield of its grain in our country is 2.5 t / ha, while in France it reaches 6.09 t / ha, Great Britain - 5 , 67, Germany - 5.69 t / ha [2]. Therefore, there is a need to find ways to increase the productivity of spring barley in specific conditions of its cultivation. One of the main ways to increase crop productivity is the stable growth and development of spring barley. Development is the formation of specialized organs and parts of aplant to perform its main biological function: the preservation of its species. Of particular importance in the cultivation of cereals are the processes of growth and development that underlie the formation of grains. One of the most important problems of plant growth and development in the technology of growing crops, in particular spring barley, is its growth processes. A characteristic indicator of growth processes, which affects the formation of crop yields, is its height. During our research, a lot of attention was paid to the development of culture in the right-bank forest-steppe of Ukraine.As a result, it was found that the height of plants increased from the germination phase to full maturity, due to increased plant biomass and depended on varietal characteristics and technological methods of cultivation and hydrothermal regime of years of research. Higher plant height in the phase of full maturity was observed in the variety Aizhan - 55 cm, and in the variety Aristei - 50 cm. It was found that depending on the factors studied, the height of spring barley plants in the tillering phase did not change significantly, but starting from the exit phase into the tube, the difference in height was significant. The application of mineral fertilizers provided an increase in the height of spring barley plants.

The studied variety and hybrid, as well as sowing dates influenced the duration of interphase periods of table carrot plants. The interphase period "sowing – mass seedlings" was the longest during the sowing period of the third decade 03: in the variety Shantаne KL – 36 days, which is 3 days longer than the control and 12 days – from the sowing period of the third decade 04, in the hybrid Bolivar F1 – 34 days, which is 3 days longer than the control and 12 days longer than the sowing period III decade 04. The period of root formation – technical maturity lasted from 80 to 92 days. It was shorter during the sowing period of the third decade 04: in the variety Shantane KL it is 12 days shorter than the control, in the hybrid Bolivar F1 it is 8 days shorter than the control. The longest this interphase period was in table carrot plants sown during the sowing period of the third decade 03, in the variety Shantane KL – 92 days, in the hybrid Bolivar F1 – 89 days. Plants had the longest vegetation period during the sowing period of the third decade 03: in the cultivar Shantane KL – 126 days, in the hybrid Bolivar F1 – 124 days, which is 4 and 3 days longer than the control variants. The highest yield of table carrots was obtained during the sowing period of the third decade of March: in the variety Shantane KL – 41.4 t / ha, in the hybrid Bolivar F1 – 47.1 t / ha, where the increase relative to controls was 4.9 and 5.2 t / ha, respectively. The significance of this difference was confirmed by the results of analysis of variance. The studied variety and hybrid were characterized by high marketability. In general, the marketability in the experiment was influenced by varietal characteristics, as well as the timing of sowing of carrot seeds. The marketability of table carrots, depending on the variant of the experiment was 77.2 - 88.0%. The highest marketability indicator was characterized by the roots of the Bolivar F1 hybrid during the sowing period of the third decade of March – 88.0%, which is 2.7% higher than the control. According to the results of biometric measurements, the influence of sowing dates on the biometric parameters of table carrot roots was revealed. The main indicator that affects the size of the crop is the weight of the root crop. The highest mass of root crops was recorded in plants sown during the sowing period of the third decade of March: in the variety Shantane KL – 122 g in the hybrid Bolivar F1 – 128 g, which is more than the control variants by 23.7 and 25.5 g, respectively. In terms of root diameter, this indicator was the largest during the sowing period of the third decade of March: in the cultivar Shantane KL – 6.2 cm in the hybrid Bolivar F1 – 6.6 cm, which is 0.4 cm higher than the control variants, respectively. According to average data, the greatest length of root crops was observed during the sowing period of the third decade of March, where the increase relative to control was 0.2 - 0.4 cm, respectively.

The article considers the biological significance of table carrots in human life and the country's economy. It is concluded that the value of table carrots, first of all, is explained by the presence in its composition of a large set of useful substances for the vital functions of the human body. The special value of carrots is that its varieties have an orange color of roots containing carotene (provitamin A), which in humans and animals is converted into vitamin A. Named the most promising hybrids of carrots, lists the basic climatic requirements for growing high yields of this vegetable. The most important conditions of organic carrot cultivation are briefly described. The stages of the technological scheme of carrot cultivation by organic technology are described and the influence of organic cultivation technology on the biometrics of the carrot plant in 2018–2020 is estimated. Analyzing the results of a field experiment on organic cultivation of table carrots, we can say that as a result of organic cultivation and simultaneous application of organo-mineral fertilizer HelpRost vegetables or HelpRost Boron plant height of Abaco F1 hydride was the highest and amounted to 76 cm, which exceeded the height of control plants almost 1.5 times. The variants in which the Abaco F1 and CB 7381 MS F1 hybrids were grown were characterized by the corresponding length. In these variants, the length of the root was the longest and was 16 and 17 cm, respectively, which exceeded the control variant by 4 and 5 cm, respectively. It was found that the bacteria Azotobacter chroococcum and Bacillus subtilis of the biological product of BTU-Center and chelated microelements, improve the biometrics of the plant and root crop (most positively for the root of Abaco F1 hydride where their value can be 5.1 cm. The yield of table carrot hybrids using organic technology, t / ha for 2018–2020 was studied and it is said that the highest yield can be obtained by growing Abaco F1 hybrid, where its value reaches 68 t / ha . During the cultivation of hybrids Bolivar F1 and SV 7381 MS F1 the yield is lower, is only 61.0-62.5 t / ha and exceeded the yield of Olympi F1 hybrid by 9 and 6%, respectively.

Two-tester analysis of topcross crossings of soybean varieties, which differ in valuable economic traits and ecological and geographical origin, was used in the research. According to the indicators of combining ability, the value of soybean varieties was determined by the elements of the crop structure. In hybrid populations, the degree and frequency of positive transgressions have been determined, which is a selection material for the creation of new varieties by hybridization. High effects of ZKZ on plant height and attachment of lower beans were established in Sawyer 2-95 variety and KiVin tester; by the number of productive nodes - in the varieties Sawyer 2-95, Medea, Kyivska 97 and tester KyVin; according to the number of beans per plant - in varieties Ustya, Kyivska 97 and tester KyVin; according to the number of seeds on the plant - in the Medea, Kyivska 97 and Hoverla tester varieties; by the weight of 1000 seeds - in varieties Sawyer 2-95, Kyivska 97 and Hoverla tester; according to the mass of grain from the plant - in the varieties Medea, Kyivska 97 and tester Hoverla; in terms of productivity - in Medea, Kyivska 97 and tester Hoverla varieties. It was established that additive effects of genes were dominant in the genetic control of plant height traits and attachment of lower beans, elements of crop structure and productivity, but there was also a significant non-additive effect. According to the number of beans per plant, the number of seeds per plant, and the weight of seeds per plant, in the vast majority of hybrid populations, inheritance by the type of overdominance and dominance of the parental form with a higher manifestation of the trait was noted. The analysis of dominance indicators made it possible to identify crossbreeding combinations that are distinguished by the overdominance of the specified traits and have significant breeding value: Sawyer 2-95 × Hoverla, Kyivska 97 × Hoverla, Kharkivska precocious × Hoverla, Sawyer 2-95 × KiVin, Kharkivska precocious × KiVin.

The article presents the results of research on the study of ornamental grasses. In general, a separate area in modern landscape design, which features a focus on the use of perennial herbaceous plants in general and cereals in particular, their shape and texture is called "New Wave". The landscape movement is also based on the principles of growing a garden as a stable and self-reproducing system, the landscape of which naturally evolves from season to season. A study of current trends in landscaping of urban areas has shown that floral design is an integral tool in creating an aesthetically attractive, comfortable and environmentally sustainable space of the city.

Due to global and rapid changes in climatic conditions for the cultivation of major crops, there is an urgent need for the selection of adaptive varieties that will not reduce their productivity. In modern agricultural production, the variety is the biological foundation on which all elements of cultivation technology are based. If you choose the right variety, it will enhance the effect of other factors. Conversely, if the manufacturer makes a mistake with the chosen variety, it will weaken the effect of all other factors. In agricultural production, it is difficult to predict the outcome, because the existing approaches to soybean cultivation are 70% dependent on soil and climatic conditions. To solve this problem, you need to carefully select adaptive varieties of soybeans. In Ukraine, a fairly large range of soybeans of different maturity groups. In conditions of intensive agriculture with extreme weather conditions, it is important to grow several varieties of different maturity groups on farms. The article highlights the results of the analysis of the State Register of plant varieties suitable for distribution in Ukraine, as well as analysis of research by other scientists on the basis of which we chose two adaptive varieties of different maturity groups with genetic potential of 4-5 t / ha Ukrainian and foreign selection: Ukrainian ( early-ripening variety Nugget) and Canadian selection (early-ripening variety Amadeus). These varieties are adapted for growing in the Forest-Steppe zone, have high resistance to lodging and shedding. Resistant to soil moisture deficiency, high temperatures and drought-resistant in summer, which is relevant in climate change. The height of attachment of the lower beans in the nuggets Nuggets and Amadeus 13 cm, which determines its suitability for full mechanized cultivation from sowing to harvesting. Phenological observations of seedlings of the studied varieties according to the scheme: Factor A - variety: Nugget, Amadeus. Factor B - inoculation. Factor B - foliar feeding. The experiment was laid on the experimental site of 0.06 ha. The seeds were treated with BTU-t Bioinoculant at the rate of 3 kg / t of seeds, the control was not processed. After the mass emergence of seedlings, it was found that the seeds treated with bioinoculants came out a little later than the control, because bacteria slow down the germination of seeds.
由于主要作物种植的全球气候条件的快速变化,迫切需要选择不会降低其生产力的适应性品种。在现代农业生产中,品种是所有栽培技术要素的生物学基础。如果你选择了正确的品种,它会增强其他因素的效果。相反,如果制造商在选择品种上犯了错误,则会削弱所有其他因素的影响。在农业生产中,很难预测结果,因为现有的大豆种植方法70%依赖于土壤和气候条件。为了解决这个问题,你需要仔细选择适应性强的大豆品种。在乌克兰,有相当大范围的不同成熟度组的大豆。在极端天气条件下的集约化农业条件下,重要的是在农场种植不同成熟度组的几个品种。本文重点介绍了乌克兰适合分布的植物品种国家登记册的分析结果,以及其他科学家研究的分析结果,在此基础上,我们选择了两个不同成熟度群体的适应性品种,遗传潜力为4-5 t / ha乌克兰和外国选种:乌克兰(早熟品种nuget)和加拿大选种(早熟品种Amadeus)。这些品种适合生长在森林草原地带,有很高的抗倒伏和脱落。夏季耐土壤水分不足、耐高温、抗旱,与气候变化有关。鸡块和阿玛迪斯下部豆子的附着高度为13厘米,这决定了其从播种到收获的全机械化栽培的适宜性。按因子A -品种:金块、金丝桃。因子B -接种。因子B -叶面取食。试验场地为0.06 ha。用BTU-t生物接种剂按3 kg / t的剂量处理种子,对照组不处理。在幼苗大量出苗后,发现用生物接种剂处理过的种子出来的时间比对照稍晚,因为细菌减慢了种子的发芽速度。

The article describes the results of research on the content and ratio of photosynthetic pigments in the stipules of winter peas using different cultivation technologies. The objects of the study were winter pea plants (Pisum sativum L.) of variety NS Moroz, plant growth regulator (PGR) Endofit L1 RK, bacterial preparation Bioinoculant BTU-r, microfertilizers «LF-Bobovi» and Biobor 140. The purpose of our research was to study the formation of photosynthetic pigments of winter pea plants under the action of growth regulator Endophyte L1 RK, bacterial preparation Bioinoculant BTU-r, their complex applying and foliar treatment systems with microfertilizers «LF- Bobovi» and Biobor 140. Analysis of chlorophyll and carotenoid content in alcohol extract (96.0%) was performed using a spectrophotometer Ulab − 102UV (China) at different values of wavelength: λ = 441; λ = 649; λ = 665. The volume of the working solution was 25 ml. Calculations of these indexes were performed according to the formulas of H. K. Lichtenthaler. During the study period, the influence of plant growth regulator, bacterial preparation, and foliar fertilization on the content of chlorophyll a and b, their sum, and concentration of carotenoids in the stipules of winter pea plants were evaluated. The research results indicate the dependence of these indicators on the use of the growth regulator and the bacterial drug, as well as on foliar fertilization. It was found that the implementation of foliar treatment in the phase of 3-5 stipules and complex use (in phases 3-5 of stipules and buttons) phase with tank mixtures of micro fertilizers «LF- Bobovi» (1.5 l / ha and 2.5 l / ha) and Biobor 140 (1.0 l / ha) led to an increase of the content of chlorophyll a and b, their total amount and carotenoid content. The highest content of chlorophylls a and b, their sum, and carotenoids in the stipules of winter pea plants were in the variant with the combined use of pre-sowing seed treatment with growth regulator Endophyte L1 RK (0.01 l / t), bacterial preparation Bioinoculant BTU-r (2 l / t) and at foliar treatment with microfertilizers «LF- Bobovi» (1.5 l / ha and 2.5 l / ha) and Biobor 140 (1.0 l / ha).The search for ways and opportunities to increase the grain yield of winter pea varieties Moroz due to the introduction of new technological methods of its cultivation remains relevant. A possible solution to the problem of improving the productivity of winter peas is the use of different mechanisms of action of plant growth regulators, inoculation with symbiotic microorganisms, and foliar feeding with tank mixtures of chelated microfertilizers.
本文介绍了不同栽培技术对冬豌豆托叶光合色素含量和比例的研究结果。以NS Moroz品种冬豌豆(Pisum sativum L.)、植物生长调节剂(PGR) Endofit L1 RK、细菌制剂生物接种剂BTU-r、微量肥料LF-Bobovi和Biobor 140为研究对象。本研究旨在研究生长调节剂内生菌L1 RK、细菌制剂生物接种剂BTU-r及其复合施用和微肥“LF- Bobovi”和Biobor 140叶面处理体系对冬豌豆光合色素形成的影响。用Ulab−102UV分光光度计(中国)在不同波长值下分析醇提物中叶绿素和类胡萝卜素含量(96.0%):λ = 441;λ = 649;λ = 665。工作液的体积为25 ml。这些指标的计算依据H. K. Lichtenthaler公式。在研究期间,研究了植物生长调节剂、细菌制剂和叶面施肥对冬豌豆植株托叶叶绿素a和b含量、叶绿素a和叶绿素b总量以及类胡萝卜素浓度的影响。研究结果表明,这些指标依赖于生长调节剂和细菌药物的使用,以及叶面施肥。结果表明,在托叶3 ~ 5期进行叶面处理,在托叶3 ~ 5期复合施用“LF- Bobovi”(1.5 l / ha和2.5 l / ha)和“Biobor 140”(1.0 l / ha)混合施用,可提高叶绿素a和叶绿素b的含量、总含量和类胡萝卜素含量。套用生长调节剂内生菌L1 RK (0.01 l / t)、细菌制剂生物接种剂BTU-r (2 l / t)和叶面微肥“LF- Bobovi”(1.5 l / ha和2.5 l / ha)和Biobor 140 (1.0 l / ha)处理的冬豌豆植株托叶叶绿素a和叶绿素b含量、总含量和类胡萝卜素含量最高。由于引进了新的栽培技术方法,寻找方法和机会来提高冬豌豆品种莫罗兹的籽粒产量仍然是有意义的。提高冬豌豆产量的一个可能的解决办法是利用植物生长调节剂的不同作用机制,接种共生微生物,以及用螯合微肥料的罐混合物在叶面上饲喂。

In the course of research, varieties of common bean were selected, which were distinguished by stable indicators of the duration of the growing season, which depended to a lesser extent on the hydrothermal regime of the conditions of the years of research. This will contribute to the formation of a stable growing season in dry and optimal years of research in terms of moisture supply. The highest coefficients of repeatability were noted in varieties of common bean: UD0301786 - 0.98, with a coefficient of variation (V) - 1%; UD0302656 – 0.97, coefficient of variation – 1%; UD0300495 – 0.95, coefficient of variation – 1.45%; UD0302223 – 0.95, and the coefficient of variation – 1.34%; UD0302398 – 0.95, coefficient of variation – 1.33%; UD0300019 is 0.95, and the coefficient of variation is 1.3%. The weight of 1,000 grains affects the grain productivity, while, as already noted, varieties with low variability of the weight of 1,000 grains belong to drought-resistant ones. Higher values of the mass of 1000 grains compared to the standard and, at the same time, lower variability according to statistical indicators were identified in the variety samples: UD0300577 – 284.7 g, repeatability coefficient – 0.9, variation coefficient – 7%; UD0303753 – 274.5 g, repeatability coefficient – 0.9, coefficient of variation – 7.1%; UD0300004 – 265.4 g, repeatability coefficient – 0.86, coefficient of variation – 9%; UD0303398 – 243.4 g, repeatability coefficient – 0.91, coefficient of variation – 6.0%; UD0302256 – 234.6 g, repeatability coefficient – 0.9, coefficient of variation – 8.4%; Yield is a summary feature, the level and stability of which are affected by resistance to diseases and pests, drought resistance, heat resistance, cold resistance, and manufacturability.Higher yield and lower variability compared to the standard was noted only in variety samples: UD0300577 – 333.0 g/m², repeatability coefficient – 0.98, and variation coefficient – 4.5%; UD0303753 is 329.0 g/m², repeatability is 0.97, and coefficient of variation is 7.1%. The vast majority of variety samples were characterized by higher variability in the level of productivity, this is due to the influence of adverse growing conditions that cause stress.
