One of the factors of increasing the efficiency of the horticulture industry in modern market conditions is high–quality planting material. Given the high labor intensity of planting material production and the lack of special equipment in nursery breeding, special attention should be paid to the introduction of effective methods and methods of reproduction. The most common way to obtain seedlings of berry crops is green cuttings. The increasing popularity of early berry crops causes an increase in demand for their planting material. To increase the production of seedlings, it is necessary to improve their cultivation technology. In addition, the variety of decorative advantages of honeysuckle attracts the attention of gardening specialists. The influence of growth regulators on the reproduction by green cuttings of four varieties of edible honeysuckle in the conditions of the Republic of Tatarstan has been studied. In the variant with the use of the stimulator \"Kornevin\", a higher percentage of rooting of cuttings was established compared to the control from 79.9 to 85.4%. Varietal influence on the rootability value was also noted, so the highest percentage of rooting of green cuttings was characterized in the Blue Spindle and Azure varieties - 81.9 and 85.4 percent. Treatments of green cuttings of edible honeysuckle with root formation stimulators had a significant impact on the yield of standard seedlings. The use of the drug \"Zircon\" for processing green cuttings of honeysuckle varieties provided the maximum yield of standard planting material in the experiment from 57.2% to 68.2%. Thus, as a result of our research, it was proved that the positive effect on the rooting and growth of roots was positively affected by the treatment with rhizome, and the output of standard seedlings was favourably affected by the treatment with zircon.","PeriodicalId":198484,"journal":{"name":"Agrobiotechnologies and digital farming","volume":" 34","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139623968","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 dynamics of buckwheat yield from 2000 to 2022 was considered, the average yield was equal to 10,5 c/ha. The range of yield fluctuations in the study years turned out to be 13,0 c/ha. The highest yield was recorded in 2008, when humidification conditions were favorable for the development of buckwheat plants, while the minimum figure was recorded in 2010 due to lack of precipitation and high temperature tension, which negatively affected the growth, flowering and maturation of the crop. To assess the dynamics of buckwheat yield development over time, indicators characterizing the dynamics of time series were analyzed. During the study period, variable dynamics of buckwheat yield was observed in the Republic of Tatarstan. The maximum increase was in 2011 compared to the previous year and amounted to 9,6c/ha, which is an increase of 355,6 %. The highest yield rates were recorded in 2011 and 2022 – 455,6 % and 226,9 %, respectively. The minimum rates of buckwheat yield in Tatarstan were noted in 2010 (22,7 %), 2021 (55,3 %) and 2018 (68,2 %). Air temperatures of the month of May, June and July during the periods 2000-2010 and 2011-2022 were compared. It was found that in the period 2011-2022 the average air temperature of the months considered is 0.8-1.0 °C higher than in 2011-2022. Analysis of the correlation of yield with the main meteorological indicators showed that air temperatures in June and July and precipitation in June play an important role for high yields.","PeriodicalId":198484,"journal":{"name":"Agrobiotechnologies and digital farming","volume":" 36","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139624920","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 effectiveness of such systems is achieved with the help of new ways of processing information and mathematical characteristics of technology processes. Based on the study of the main methods of creating discrete chemical and technological systems (CTS), the expediency of using the design of Petri nets (SP) to simulate the process of wastewater treatment of livestock farms (OSWF) was developed. To characterize the system, we use N–schemes, which are based on the mathematical system of the joint venture, which can form a network structure both in analytical form for automating work during analysis, and in graphical form to create visibility of the created model. Analyzing technological and chemical processes, it is important to take into account the formality condition of N–circuits, which assumes that the circuits do not take the properties of simulated systems in time, since the timing of the transition is taken to be zero. We took into account these conditions and proposed updated Petri nets that are focused on the analysis and simulation of discrete CTS, by changing the time delay of labels on transitions and positions, as well as by enabling transitions that are in priority. We have created a model in the form of a modified updated Petri net (SME). With the help of SCADA TRACE MODE technologies, we have developed a whole software package for the control system in the process of OSWF. This system can perform dispatching monitoring of the main parts of the control apparatus, as well as stop and analyze and monitor its condition, this is feasible both in general and within the framework of forecasting the occurrence of emergency situations.","PeriodicalId":198484,"journal":{"name":"Agrobiotechnologies and digital farming","volume":"9 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":"127268172","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}
