The purpose of the research was to determine the effectiveness of the complex application of biological preparations in grain sorghum crops to control brown spotting and their impact on the crop yield level in Ukraine. Methods. The study of the effectiveness of complex biological protection for the control of brown spotting of grain sorghum was carried out during 2018–2022 by conducting surveys of agrocenoses in the conditions of the educational and research field of the Polish National University and PE \"Chaykivka\" of the Radomyshl district of the Zhytomyr region. Field and laboratory methods were used to conduct the experiment. Results. The causative agent of brown spotting of grain sorghum is the fungus Helminthosporium turcicum (Luttr.) K.J. Leonard & Suggs. During the research, the first spots on the leaves were visible already in the first decade of June, and the development of brown spotting of sorghum did not exceed 1.6%. The disease reached its maximum development in 2022 and was 29.5%. It was possible to achieve the maximum reduction in the development of brown spotting in sorghum crops as a result of two-time spraying of the cenosis with biological preparations, which reduced the level of the development of the disease by 10.7% in the phase of milky-waxy grain ripeness. Complex application (two-time spraying with biopreparation Agat-25K, PA, 0.03 kg/ha and plant growth regulator Endophyt EM-1, v.s.r., 0.010 l/ha at the 30th stage of development) provided the maximum value of technical efficiency - 39.5%.

Methods. System analysis, field, laboratory, comparative calculation. Results. In the first year of using the herbage during chemical soil reclamation, the alfalfa-grass grass mixture contained 50.4-52.0% of the legume component, without liming - 40.8-42.1%. In the third year of use on the produced plots, alfalfa also dominated the botanical composition of the herbage and occupied 50-53.1%. In areas without chemical soil reclamation, the share of sowing alfalfa has sharply decreased - to 10.5-13.4%. Among the sown cereals in the herbage, tall fescue prevailed. The share of this species grew, reaching a maximum of 41.9-42.4% in the third year of use. The species composition of the herbage significantly changed depending on the mowing. Thus, grasses dominated in the first mowing on non-deoxidized areas, the share of which was 53.9-54.5%, including tall fescue 31.4- 32.2%, timothy grass 15.4-16.8%. The share of alfalfa in the first cut was 25.1-27.3%. Soil liming increased the share of the legume component in the first cut to 46.1-47.4%. The share of grass was also high and amounted to 42.1-42.2%. In the second cut, the proportion of alfalfa increased to 26.1-30.2% in the variants without soil deoxidation and to 65.3-68.0% in the variants with limestone flour. Conclusions.The introduction of limestone flour was the most effective factor in changing the species composition of the studied agrophytocenosis. In the limed areas, the share of alfalfa was high during all three years of grass stand use and amounted to 50.0-59.2%.

To evaluate the productivity of feed grass stands of the Sinyuha variety alfalfa according to yield indicators, quality and nutritional value of green mass harvested in the phases of budding and flowering to establish their value for the use in livestock industry in conditions of northern Podillia. Methods. Field experiment (visual and phenological observations of the growth and development of alfalfa plants), calculation, thermostatic, mathematical-statistical. Results. The studies were carried out in the field experiment of the Khmelnytskyi state agricultural research station of the Institute of Feed Research and Agriculture of Podillya of NAAS during 2019-2020 on podzolized medium loam black soil. The optimal phase of mowing alfalfa in the feed grass stands of the fourth-fifth years of life was determined. It is the budding phase, in which the feed productivity of the crop increased: the yield of green mass in the sum of four mowings, which was 2.5 t/ha or 5% higher. Despite a slight difference in dry matter content, its total yield was practically equal to that of the flowering phase. The studied phases of mowing had an impact on the feed productivity of alfalfa. It has been established that, in terms of quality and nutritional value of the leaf-stem mass, a greater accumulation of nutrients occurred during the mowing of alfalfa in the budding phase, when the gross yield of the sum of cuttings was: feed units – 8.78 t, crude protein – 2.39 t, gross energy – 151.52 GJ and exchange energy – 92.12 GJ. Conclusions. To ensure high yields and good feeding qualities of the Sinyukha variety alfalfa grass stands of the fourth-fifth years of cultivation in conditions of northern Podillia, mowing in the budding phase should be applied, what will contribute to the increase in the total yield of green mass with a slight difference in the total dry matter yield and increase in gross yield: feed units, crude protein, gross and metabolizable energy relative to the flowering phase.","PeriodicalId":384529,"journal":{"name":"Feeds and Feed Production","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127300430","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}

To study the effectiveness of pre-sowing seed treatment in combination with the plant growth and development stimulation in growing soybeans at different levels of mineral nutrition and assessing the competitiveness of these elements of soybean cultivation technology. Methods. Field, calculation and weight, statistical. Results. Research was conducted by the Khmelnytskyi State Agricultural Research Station of the Institute of Feed Research and Agriculture of Podillia of NAAS during 2016-2018 on podzolized, medium loamy black soils. The weather conditions of the growing season during the years of research were characterized by fairly high average daily temperatures, a large amount of unevenly distributed precipitation and a significant shortage of it in certain phases of soybean development, which had a significant impact on the formation of seed yield. Summarizing the results of the research, we found that the improvement of mineral nutrition provided an increase in yield, compared to the control, by 23.2-28.3% – under application of N32P32K32 and by 52.9-65.4% – under application of N48P48K48. At different levels of mineral nutrition, pre-sowing treatment of seeds with a growth stimulator and complex microfertilizers ensured an increase in productivity by 5.8-7.6%, one-time foliar feeding of soybeans in the phase of 2-3 true leaves – by 8.9-12.7%; budding – by 11.0-14.8%, two-time treatment of the crops in these phases – by 19.4-27.0%.

To substantiate the scientific and theoretical foundations of the formation of feed centers in the united territorial communities in conditions of limited resources and to solve the problem of providing the population with livestock products. Methods. The dialectical method of scientific cognition, observation, comparison, abstract-logical and statistical-analytical analysis, graphic-illustrative method. Results. The peculiarities of the development of livestock in Ukraine in modern economic conditions are determined. The problems of dairy farming under martial law in Ukraine are characterized. It is established that with a decrease in the number of cows, their productivity increases, both in large farms and in small ones. It has been determined that the level of feed supply in small farms requires improvement of the level of feed supply and the quality of diets. This problem can be solved, according to the experience of developed countries, by forming feed centers on an integrative basis within individual territorial communities. The organizational and structural structure of a feed center within a typical rural territorial community is presented. The algorithm for the formation of a complete mixed diet in a feed center for different types of farm animals is formed. The basic requirements for the organization of complete feeding of highly productive cows are outlined. Conclusions. In the context of the European integration processes of domestic agricultural production, the problem of food supply, the decline of traditional livestock industries, the migration of economically active population, in particular from rural areas, the development of small-scale livestock production is becoming increasingly important. The formation of integration formations based on cooperation will help to solve the problem of providing the population with livestock products, employment of the rural population and socio-economic development of territorial communities.","PeriodicalId":384529,"journal":{"name":"Feeds and Feed Production","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129639959","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}

To experimentally substantiate the effectiveness of the processes of mowing alfalfa and alfalfa-cereal mixtures with mower-conditioners with a roller and hammer types working bodies. Methods. The research was carried out in the technological process of intensive harvesting of pressed hay into rolls with the use of a trailed mower-conditioner with side traction, equipped with chevron ribbed rollers and metal vshaped hammers. Raw material: freshly cut green mass of alfalfa in the phase of budding-the beginning of flowering; alfalfa-cereal mixture (perennial ryegrass ‒ at the beginning of earing), the share of cereal grasses ‒ 22.4-36.8% of dry matter. Results. It was established that the indicators of the intensity of dehydration for alfalfa in pure crops were 1.66-1.81%/h; alfalfa-perennial fenugreek mixture ‒ 1.24-1.48%/h (I and II mowers), drying time in optimal weather conditions ‒ 3 days. The technology of active field drying of leguminous grasses with the use of a disc mower-tender with roller and bitter working bodies involving wideband stacking of the mass for drying, significantly accelerated the rate of moisture release of leguminous grasses and mixtures. Harvesting technology involves: mowing with a disc mower with flattening and stacking of the mass in a wide-band roll; one-time turning at 60-65% humidity; introduction of preservatives. The capacity of the rolls when mowing according to the technology variants was: for the Sinyuha variety alfalfa ‒ 12.9 kg/running m, for the alfalfa-cereal mixture (with perennial fenugreek of the Ruslana variety) ‒ 15.3 kg/running m. Conclusions. To intensively increase the rate of field moisture transfer of the green mass of alfalfa and its mixtures with perennial fenugreek, it is advisable to use the process of the stream dynamic flattening (under favorable weather conditions) and combine it with wide-band stacking.

The results of research on the content of organic and mineral substances in various types of perennial grasses feed, its nutritional value and energy intensity on sod-podzolic soils of the Carpathian region are presented. Conclusions. Nitrogen has the most positive effect on the chemical composition of cereal grass stands. With the fractional application of nitrogen fertilizers in a dose of N90 under each mowing against the background of application of P60K60, the content of crude protein in the dry mass of various types of grasses increased from 10.3-11.5% to 14.5-15.6%, or by 3.1- 4.0%, protein – from 7.6-8.0% to 10.0-10.8%, or by 2.2-2.4%, as well as tendentious crude fat, and the content of nitrogenfree extractive substances decreased from 46.8-51.2 to 41.9-45.9%, or by 4.2-4.9%. At the same time, the supply of digestible protein of the feed unit increased from 107-110 g to 142-152 g, or by 35-42 g. With the application of P60K60, compared to the variant without fertilizers application, the phosphorus content in the dry mass of grasses increased by 0.02-0.04% and that of potassium – by 0.20-0.36%. Most of these mineral elements, as well as raw ash, were accumulated by the Dactylis glomerata.
