The article presents the results of research on the biological activity of gray forest soil depending on the systematic use of organic and mineral fertilizers. It is established that effective reproduction of humus in gray forest soil is provided by organo-mineral (12 t of manure together with N80P60K80 application per 1 ha of crop rotation area) and organic (24 t/ha of manure), respectively 36,5 t/ha, and 35,6 t/ha. The application of only mineral fertilizers in the norm of N80P60K80 per 1 ha of crop rotation area resulted in a decrease in humus reserves by 9 % relative to the initial level (32,4 t/ha). The highest degree of humification of organic matter provided the option of applying organic fertilizers (60 t/ha) both separately – 36,0% and compatible with mineral – (60 t/ha manure + N80P60K80) – 34 %. Prolonged use of organic and mineral fertilizers in crop rotation significantly increased the total number of microorganisms in the soil. The result was increased decomposition of organic matter and increased release of CO2 from the soil. The areas with the highest biological activity and CO2 intensity were characterized by areas where the soil was systematically enriched with fresh organic matter. The intensity of biological processes in the organo-mineral system increased by 67 % relative to the variant without fertilizers and by 30 % relative to the variant with only N80P60K80. The use of organic and mineral fertilizers in one system stimulated the process of decomposition of fiber – at the level of 78,5 %, which in percentage terms exceeded the value of the indicators obtained for a purely mineral fertilizer system.

The article presents the results of studies of the systematic use of organic and mineral fertilizers on the parameters of fertility of gray forest soil and the formation of productivity of winter wheat. It was found that in a five-saw field crop rotation, the formation of ground backgrounds with different physical and chemical properties is observed. The application of bedding manure at a dose of 60 t on ha and against the background of moderate fertilization rates (N50-100P30-60K50-100) contributed to the neutralization of the soil solution to values of slightly acidic reaction (pH – 5,1), while in the absence of manure (mineral system fertilizers) pHcontinued to remain within the acidic reaction. The organic-mineral fertilization system (12 t on ha of manure + N100P60K100) and organic (12 t on ha of manure per 1 ha) turned out to be effective in terms of the humus of the soil regime, in accordance with the total humus content was 1,30 % and 1,32 % which in percentage terms is 18 % and 20 % higher compared to the option without fertilization – 1,10 %. Optimization of the parameters of the nutrient regime (mobile forms of phosphorus and potassium) of the soil at the end of the rotation was provided by the organo-mineral fertilization system (N100P60 K100 against the background of 60 t on ha of manure). A clear tendency to an increase (by 27 mg on kg) of the content of mobile potassium was determined, compensating for its constant deficiency in the soil, and by an increase of 38 % in mobile phosphorus. The highest productivity of winter wheat (5,45 t on ha) was provided by the organo-mineral fertilization system (60 t on ha of manure + N100P60K100), which is 78 % higher than the control (without fertilizers), under these conditions the greatest increase in protein was obtained – 0,63 t on ha.
本文介绍了有机肥和矿肥系统施用对灰色森林土壤肥力参数和冬小麦生产力形成的影响。研究发现，在五锯轮作中，形成了具有不同物理和化学性质的地面背景。在适度施肥(N50-100P30-60K50-100)的背景下，施用60 t垫肥有助于土壤溶液中和微酸性反应值(pH - 5,1)，而在没有肥料(矿物系统肥料)的情况下，pH继续保持在酸性反应范围内。有机-无机施肥系统(12吨/公顷粪肥+ N100P60K100)和有机施肥系统(12吨/公顷粪肥/ 1公顷)在土壤腐殖质方面被证明是有效的，根据腐殖质总含量为1.30%和1.32%，按百分比计算，比不施肥的选项- 1.10%高18%和20%。轮作结束时，有机-无机施肥系统(N100P60 K100，每公顷粪肥60 t)优化了土壤养分状态参数(磷和钾的流动形态)。测定了流动钾含量明显增加的趋势(每公斤增加27毫克)，弥补了土壤中钾的持续不足，流动磷增加了38%。有机肥+ N100P60K100处理的冬小麦产量最高，为5.45 t / hm2，比对照(不施肥)提高78%，蛋白质产量最高，为0.63 t / hm2。

In connection with the development of organic vegetable growing in Ukraine, the topical issue of courgette breeding is the creation of varieties and hybrids of F1 with maximum adaptability to soil and climatic conditions of cultivation. The purpose of research is to identify genetic sources for the breeding of courgette with a stable manifestation of biochemical characteristics of the fruit. Breeding work was carried out with 20 lines of courgette of different geographical origin. Evaluation of linear genotypes was performed on the following indicators – general (GACi) and specific adaptive capacity (SACi), relative stability (Sgi), coefficient of ecological plasticity (bi) and selection value (BVGi). Courgette lines with a high content of dry matter, total sugar and vitamin C in fruits in the phase of technical ripeness have been created. Among them, 2 highly adaptive lines, which simultaneously exceeded the standard variety Chaklun in terms of dry matter content (4.46… 4.71%) and total sugar (2.77… 2.84%). Highly adaptive lines, better than the standard grade for the manifestation of one feature - the dry matter content – 1 line (4.58%), total sugar – 3 lines (2.72… 2.77%), vitamin C – 2 lines 14.93… 15.55 mg / 100 g). Low dependence on growing conditions at the same time on the manifestation of 2 traits (dry matter content and vitamin C in the fruit) was demonstrated by 3 lines (-1 Less than bi Greater than 1). The obtained lines are a valuable source material for the creation of varieties and hybrids of courgette F1, suitable for organic cultivation technologies with high quality fruits in the phase of technical maturity.

The article presents the results of studies on the effect of postemergence herbicides and their tank compositions on soybean weeds. It was found that the use of Miura allowed to reduce the level of total weediness of crops, at the time of harvest by – 75 78 %, the raw weight of weeds – by 19– 46 %. It is established that the use of the tank mixture Harmony – 3 g on ha + surfactant Trend 0,2 l on ha + Bazagran – 1.5 l on ha, afte 8-10 days Harmony – 5 g on ha and the use of anticereal drug Miura – 0,4 l on ga. With the introduction of such a tank mix, the death of dicotyledonous species a month after application reached 93 %, and the death of cereal weeds was – 84 %. The weight of those weeds that remained in the agrocenosis was 52 g on m2, which is 87 % less than the control. The use of Harmony – 8 g on ha + Bazagran – 1.75 l on ha and the anti-cereal product – Miura – 0,6 l on ha helped to reduce the total weediness of crops by 86 % a month after the application of herbicides. The death rate of dicotyledonous weeds was 83 %. The total weight of weeds before harvest decreased by 91 % compared to the control and was 62 g on m2.The maximum soybean harvest – 2,45 t on ha provided the use of a mixture of Harmony – 3 g on ha + surfactant Trend – 0.2 l on ha and Miura – 0.4 l on ha. Comparing yield were absent, this indicates that soybean yields inherbicide variants were lower.The studies herbicides and their compositions showed high selectivity to soybean plants. By reducing the level of weeding, they contributed to an increase in yield by 0,57–1,11 t on ha. Under conditions of mixed weeding, the following mixtures of post-emergence herbicides were the best: Harmony – 3 g on ha + Bazagran – 1,5 l on ha in 8-10 days Harmony – 5 g on ha and Miura – 0,4 l on ha; Harmony – 8 g on ha + Bazagran – 1,5 l on ha and Miura – 0,6 l on ha.

Tomato grafting has a considerable scientific and practical interest, because it promotes plant resistance to illnesses, pests, stress factors, improves nourishment conditions and as a result increases crop yields and contributes to the greening of cultivation. The study of this issue is actual for the indoor ground conditions, particularly, for growing in glass greenhouses using low-volume hydroponics method. Experiments for studying three indeterminate hybrids of tomatoes Torero F1, Barteza F1 and Merlice F1 with grafting on rootstocks Maxifort F1, TD-1 F1 і Emperador F1 were conducted in the “Venlo” type on Private Joint Stock Company «Сombinat «Teplychnyy» («Комбінат «Тепличний»). The main goal of the experiments was to find out the efficiency of varietal-rootstocks combinations on the inderterminate hybrids F1 tomato. Consequently, the usage of rootstocks promotes the increase in early yield in all options. Significantly higher yield compared to the plants that were not rootstocked during all the years of research, was gotten from the Toreto F1 hybrid on the TD-1 F1 rootstock (in general during 3 years 30,4 kilograms per square meter), from Merlice F1 hybrid on Emperador F1 (31 kilogram per square meter). Mathematically significant difference in early yield between the studied cultivar-rootstock combinations was not found. The usage of the rootstocks also improves biochemical indicators, particularly, contributes to the increasing the dry matter content in the fruits of all hybrids by 0.1-0.8%. Emperador F1 rootstock causes an increase in the total sugar content in tomatoes by 0.3-0.5% and ascorbic acid by 1-4.7% for all studied rootstocks. It is recommended to use such grafting options as Torero F1 to TDß1 F1; Barteza F1 to Emperador F1; Merlice F1 to Emperador F1 with a view to increasing the share of early yield (10th July) in modern block hydroponic winter greenhouses of the “Venlo” type at the level of 30,4-31,0 kilograms per square meter with high biochemical indicators of fruits.

Due to the intensification of production of parsnip, the question arises to clarify the elements of cultivation technology that should ensure its high productivity. The use of varietal plant resources is one of the most important parts of agriculture - the basis of economic and social development of the state. The most efficient and cost-effective is the widespread introduction of new varieties and hybrids with a genetically determined level of adaptation to the conditions of soil and climatic zones of their cultivation. The indicator of the dynamics of the formation of photosynthetic productivity is the basis of the yield of each crop. The purpose of the research was to study the dynamics of leaf surface formation in varieties of parsnip in the conditions of the Right-Bank Forest-Steppe of Ukraine. The studied cultivars of parsnip sowing formed a high area of active assimilation surface, the dynamics of which depends on the stage of organogenesis, soil and climatic conditions of the year and varietal characteristics. With the highest average for the growing season leaf area (49.0-49.6 thousand m2 on ha), photosynthetic potential (1.79-1.83 million m2 per day on ha) and net productivity of photosynthesis - 5.56 g on m2 per day) were characterized by varieties Stymul and Pulse in terms of other varieties. It is established that in order to obtain stably high yield (44.4-45.4 t on ha) and marketability of root crops (85-93%) in the conditions of the Right-Bank Forest-Steppe of Ukraine it is necessary to sow highly productive varieties of parsnip sowing Stymul and Pulse.
