The intrinsic potential of this crop, as highlighted by the authors, instigated a keen interest in its investigation. (Research purpose) To conduct research on the cultivation of trititrigia Pamyati Lyubimovoy (In Memory of Lyubimova) in the semi-arid southern zone of the Rostov region. (Materials and methods) Trititrigia was cultivated on typical chernozem soil with carbonate content, characterized by heavy loamy texture, in conditions of insufficient and unstable moisture, following the zonal technology for cultivating winter wheat. The main pre-sowing tillage was performed using a shallow method by a combined KUM-4 unit. For seed sowing, the «Demetra» selective seeder was used. Throughout the trials from October 2020 to August 2022, meteorological conditions were taken into account, including precipitation levels and air temperature. Using two crops as examples, the biometric data of trititrigia plants, yield structure elements, combine yield and drought resistance were studied. (Results and discussion) It is determined that trititrigia Pamyati Lyubimovoy (In Memory of Lyubimova) aligns with the declared parameters in terms of plant height, ear length, and duration of the vegetative period. The plant development type of trititrigia is identical to winter wheat. (Conclusions) It is established that trititrigia Pamyati Lyubimovoy (In Memory of Lyubimobva) shows low resistance to drought within a semi-arid climate. Additionally, the straw yield surpasses the grain yield by a factor of four, while the weight of 1000 grains is low at 23.58 grams. Moreover, the combine yield (3.80 tons per hectares) falls short compared to the winter wheat variety Stanichnaya (5.09 tons per hectares). Further investigations into trititrigia within a semi-arid climate are considered necessary to determine its cultivation feasibility.","PeriodicalId":32503,"journal":{"name":"Sel''skokhoziaistvennye mashiny i tekhnologii","volume":"179 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136313413","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}

As a result, the area of soil compaction arising from tractor wheel pressure increasingly covers the plant's protective zone. This poses challenges for both root system growth and development, as well as the optimal uptake of soil nutrients, often leads to plant damage or even trampling. Presently, there is no universally accepted metric for assessing the compatibility between tractor track width and the specific inter-row spacing under cultivation. (Research purpose) Development of an indicator to assess the compatibility of the tractor track width with the cultivated inter-row spacing. (Materials and methods) The analysis demonstrates that the level of compatibility of the tractor track to the crop inter-row spacing is determined based on the dimensions of the crop spacing, the tractor track width, the protective zone outlined by agrotechnical standards, the deviation of the wheel trajectory from the axis of row symmetry, and tire size. (Results and discussion) An analytical correlation has been derived to determine the level of compatibility between tractor track width and crop inter-row spacing, using the context of cotton cultivation as an illustrative example. It has been revealed that among the serial tractors utilized within cotton farms across the region, full-fledged operational performance is exclusively achieved when row spacings measure 60 and 90 centimeters. In contrast, the utilization of this machinery on row spacings of 70 and 76 centimeters leads to detrimental outcomes such as row trampling and plant damage. (Conclusions) The viability of the developed indicator has been determined and validated. The improvement of the tractor propulsion system should be aimed at devising a technical solution that facilitates seamless adjustment of track width over a broad spectrum, thus allowing for adaptability to diverse row spacing requirements.","PeriodicalId":32503,"journal":{"name":"Sel''skokhoziaistvennye mashiny i tekhnologii","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136308519","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}

(Research purpose) The research aims to substantiate the thickness of narrowing partitions in the vertical deep aspirating channel. (Materials and methods) A prototype of a vertical deep aspirating channel with three sections of varying height, was used for cleaning soybean seeds. The optimal thickness of the narrowing partitions in the channel has been justified. Impurity extraction completeness and seed separation efficiency within a vertical aspirating channel were assessed for soybean seed cleaning under maximum specific grain load conditions. (Results and discussion) The following parameters have been determined: the optimal thickness for the narrowing partitions is 70 millimeters under a maximum specific grain load of 5 kilograms per square centimeter per hour. Seed losses do not exceed 3 percent in the aspirating channel with narrowing partitions, with impurity extraction completeness of 74 percent for the «Waste» fraction. The efficiency of the separation process stands at 71 percent, and the purity level of the «Seeds» fraction reaches 81 percent in a single pass during the preliminary cleaning stage.

It also introduces the equation governing the movement of this working body, thereby enabling the determination of the fundamental geometric parameters of the mechanism. (Research purpose) To develop the technology for fiber flax stripping at a flax mill using the proposed comb-type device, and to examine the parameters and modes of its functionality. (Materials and methods) A testing model was designed for a stripping machine, enabling an exploration of the flax combing process within the factory. The limitations of the parameters under investigation were identified. Furthermore, a theoretical model was formulated to calculate the performance of the stripper. (Results and discussion) The operation kinematic mode, stripping cleanliness, and seed losses during the stripping process are determined through theoretical analysis. It is discovered that the quality of stripping is influenced by the thickness of the flax ribbon. Specifically, an increase in the flax straw's thickness results in the clogging of the stripping device, subsequently leading to the formation of tangles and entanglements on the working body. On the other hand, insufficient thickness of the flax ribbon leads to significant damage to the stems. The limits for the thickness of the flax ribbon are established considering both the potential minimum and maximum yields: the lower limit being 0.01 meters and the upper limit set at 0.05 meters. The application of the factory's stripping technology is expected to ensure a 10 percent reduction in seed losses and an additional 6 percent reduction in production costs. (Conclusions) Theoretical justification for the parameters and operational modes of the stripper in the flax processing line, along with its design, is provided. The feed speed of the flax ribbon is configured to range between 1.0 and 1.5 meters per second, while the rotation frequency of the working body varies from 2.2 to 3.0 revolutions per second.","PeriodicalId":32503,"journal":{"name":"Sel''skokhoziaistvennye mashiny i tekhnologii","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136309242","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}
