Spring barley (Hordeum vulgare L.) is widely cultivated as a fodder, industrial and food crop. The aim of the work is to study the features of the formation of some qualitative characteristics (laboratory germination, weight of 1000 seeds, bulk weight) of seeds of various varieties of spring barley, depending on the agro-climatic conditions of the growing season during the years of their formation. The objects of the study are 14 varieties of spring barley of domestic and foreign breeding, grown in 2020 and 2021, in the Arsk variety plot of the Predkama zone of the Republic of Tatarstan. The seeds of these varieties obtained in 2020 and 2021 were used for the study. At the same time, in 2020, the weather conditions were quite favorable for the growth and development of barley plants, and the conditions of 2021 were characterized by severely dry phenomena. Field experiments were laid in 2022 in the fields at Agrobiotechnopark LLC of Kazan State Agrarian University. At the same time, seeds of spring barley of the studied varieties of the harvest of 2020 and 2021 were sown. All seeds met the requirements of the standard for seed material. Presowing treatment of seeds was not carried out. Seeding rate - 5 million viable seeds per 1 ha. The growing season of 2022 was characterized by relatively moderate temperatures and sufficient precipitation to form a high yield. Agro-climatic conditions during the years of formation of the seed material (2020 and 2021) significantly affected the quality characteristics of the seeds of the 2022 crop. It was found that the seeds of the 2020 offspring varieties (Kamashevsky, Endan, Cornet resistant, Guzel, Zhivago) had low laboratory germination - 76%, 84%, 76%, 18%, and 68%, respectively. For the seeds of the 2021 harvest, the germination rate of the Kamashevsky and Kornet resistant varieties increased by 16%, the Guzel variety - by 58%, and the Zhivago variety - by 32%. Soratnik and Zhivago varieties showed the maximum laboratory germination from the seeds of the 2021 crop, their germination was 100%. The mass of 1000 grains of the harvest of 2022 of the variants of sowing with seeds of 2020 varied in the range from 45.9 to 59.3 g. The Nord 17/2645 variety turned out to be the most coarse - 66.5 g. Sorcerer (679 g/l). The volumetric weight of the crop obtained from the seeds of 2021 for varieties varied in the range from 640 to 690 g/l. The varieties Tevkech, Rafael, Soratnik, Eifel and Nord 17/2645 showed relatively high stability of these traits over the years.","PeriodicalId":198484,"journal":{"name":"Agrobiotechnologies and digital farming","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123465105","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}

In addition, the crop has important agronomic importance in controlling field weeds. It is one of the most important cereal crops in world agriculture. As a high-yielding crop, it plays an important role in fodder production. A powerful reserve for increasing corn yields is mineral fertilizers, as well as the widespread introduction of new zoned varieties and hybrids of corn into production. This article presents the influence of organic and mineral fertilizers with macro-, micro-, complex fertilizers and growth regulators on corn yield and production. Sufficient nutrients are necessary to obtain high yields. Various growth-promoting substances are also used in modern agricultural practice. They improve seed germination and germination energy, accelerate plant growth, plant development and increase yield. Using special mixtures of fertilizers for corn concentrates all the necessary complexes of nutrients. The necessary complex of nutrients is applied in one step, which reduces the unevenness of fertilization. Spraying of combined fertilizers containing microelements and growth regulators before sowing increases plant resistance to adverse weather conditions. The use of combined compositions of NPK fertilizers allows the development of resource-saving systems and reduces the cost of fertilizers.","PeriodicalId":198484,"journal":{"name":"Agrobiotechnologies and digital farming","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127862742","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}

The territory is a poorly divided polygenetic plain with absolute heights of 140-150 m. The bedrock deposits have sandy-loamy layers of the Neogene and Pleistocene, overlain by cloaks of Quaternary deluvial loams, up to 20-21 m thick. The soil cover is dominated by leached medium–sized chernozems, which is 52.6% of the area, typical low–power and medium-sized chernozems - 39.6%, podzolized medium-sized chernozems - 2.7%, gray forest – 4.8%. The humus content in the agrogenic horizon of typical chernozems is average – 4.2-5.2%, and in leached chernozems ranges from 4.6% in a slightly washed analogue to 5.4% in full-profile representatives, where the humus content gradually decreases to the soil-forming rock. The potential reserves of humus of the studied subtypes of chernozems according to typical sections are in the range from 230 t/ha to 462 t/ha. According to the materials of the agrochemical survey for 1972-2021, the dynamics of the content of mobile forms of phosphorus in the arable horizon ranged from 103 mg/kg to 158 mg/kg. The weighted average amount of mobile potassium gradually decreased from 140 mg/kg to 101 mg/kg of soil. The actual yield of spring wheat and the dynamics of the content of mobile forms of potassium over the years of observation have a reliable correlation between each other. The obtained regression equations can be used to predict the yield of spring wheat in a given area. According to the results obtained, for each hectare of arable land for 51 years, about 149.9 kg of phosphorus was received with organic and mineral fertilizers, and since it is sedentary and difficult to dissolve, this led to its accumulation in the soils of the territory.

Traditional beekeeping is faced with a number of issues of conservation from the negative impact of chemicals. The use of chemical preparations for plant growth in crop production has a detrimental effect on them. Today, a large number of agricultural holdings use chemicals in agriculture and forestry, while not coordinating the processing rules in the vicinity of apiaries. On the basis of the adopted Federal Law of December 30, 2020 N 490-FZ (as amended on June 11, 2021) \"On beekeeping in the Russian Federation\". According to the rules, agricultural enterprises and organizations, as a result of the use of chemicals for the treatment of honey plants, are obliged to notify enterprises, institutions, organizations and beekeepers that have apiaries within a radius of up to 7 km from the treated areas in writing or through the local press 5 days before the start of work. , report on the drug used, its toxicity and the timing of isolation. But due to the fact that there is no consistency between agricultural enterprises and apiary farms, it becomes necessary to use a modern digital service to timely identify and prevent the causes of bee death. Considering the traditional maintenance of bee colonies, the article provides the use of modern digital technologies to protect bees from external climatic and internal factors of keeping bee colonies. Based on the results of the data obtained, it is proposed to use analytical data for the timely resolution of life support issues for bee colonies. At the same time, a system of digital service for monitoring and controlling bee colonies is being considered, and the use of a digital service in beekeeping is being carried out: a smart hive, digital beekeeper programs.","PeriodicalId":198484,"journal":{"name":"Agrobiotechnologies and digital farming","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129186351","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}

They are well absorbed, as they contain all the necessary nutrients in ratios that best meet the zootechnical requirements. In addition, the absence of annual costs for tillage and sowing, as well as the ability of perennial grasses to form 3 mowing with irrigation and 2 without irrigation, allow you to get feed at the lowest cost. Most importantly, perennial herbs have a unique ability to increase soil fertility and improve its structural composition, which is an invaluable advantage in conditions of exorbitant high cost and shortage of fertilizers. In this regard, it is necessary to revise the structure of the acreage of fodder crops in the direction of increasing the area of perennial grasses to 25% of arable land against 15-18% at present (0.8-0.9 hectares per 1 conditional head of cattle). Taking into account the above, this article presents the generalized results of field experiments on the study of the cenotic activity and nutritional value of goat agrocenoses in the conditions of the Republic of Tatarstan.

Identification of the optimal age of the first calving for cows of a particular herd allows them to be operated more efficiently for a long time. The optimal age of the first calving of cows is an indirect criterion for early prediction of dairy productivity and indicators of lifetime use of cows. In this regard, the aim of the research was to study the influence of the age of the first calving on the indicators of dairy productivity of Tatarstan-type cows with different genotypes by lipid metabolism genes (OLR1, DGAT1, LEP). The research was carried out on 79 first-class heifers of the Tatarstan type in the conditions of the agricultural company \"Agrofirma Rassvet\" of the Kukmorsky district of the Republic of Tatarstan. Genotypes of lipid metabolism genes in animals were determined by molecular genetic methods, namely: PCR-RFLP analysis (OLR1, DGAT1) and AS-PCR analysis (LEP). The analysis of the complex effect of the age of the first calving and the genotypes of the genes of the low-density lipoprotein receptor (OLR1), diacylglycerol-O-acyltransferase (DGAT1) and leptin (LEP) on the manifestation of milk productivity (yield, mass fraction of fat and protein in milk, milk fat and protein yield) of cows of the Tatarstan type was carried out. Studies have shown that with an increase in the age of the first calving to 24.1-26.0 months, 26.1 months and more, Tatarstan-type cows with the genotypes OLR1/AC, OLR1/CC, DGAT1/AK, DGAT1/AA, LEP/CC and LEP/CT increased milk productivity (yield, milk fat and protein). The opposite trend was typical for individuals with the LEP/TT genotype, in which the animals with the lowest age of the first calving (up to 24.0 months) had the highest milk productivity.","PeriodicalId":198484,"journal":{"name":"Agrobiotechnologies and digital farming","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115189554","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}

Thanks to biogas plants, it is possible to mitigate the harmful effects on reservoirs and their inhabitants, reduces pollution with ammonium salts and restores the natural oxygen saturation of waters. The effectiveness of the functioning of such systems can be ensured with the help of modern methods of information processing, using methods of system analysis of complex objects based on a mathematical description of the technological process. Based on the review of the main methods of modeling discrete-continuous chemical-technological systems (CTS), the expediency of using the apparatus of the theory of Petri nets (SP) for process modeling (ASN) is substantiated. To describe the system, we propose the use of N–schemes based on the mathematical apparatus of Petri nets, one of the advantages of which is the possibility of presenting the network model both in analytical form, with the possibility of automating the analysis process, and in graphical form to ensure the visibility of the model being developed. When analyzing chemical-technological schemes, the main limitation of the N–scheme formalism should be taken into account, which is that they do not take into account the time characteristics of the simulated systems, since the transition response time is considered to be zero. Taking into account these conditions, we have proposed modified Petri nets focused on modeling and analysis of discrete-continuous CTS by including priority transitions, delay time of labels in positions and transitions. A model in the form of a modified Petri net (SME) is constructed. By means of the TRACE MODE SCADA technology, a software package of the process control system (ASN) has been developed. The process control system allows you to perform dispatching control of the main elements of the control system, stop the system (ASN) and analyze its condition, both as a whole and in order to predict the development of emergency situations.","PeriodicalId":198484,"journal":{"name":"Agrobiotechnologies and digital farming","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115338649","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}
