In tests, laboratory and field, seed treatments with Benorade and Celeste Top played the greatest stimulating role. The best results in reducing plant damage by Psylloides attenuate (Koch) 66.7 and 60.0% with a duration of protection of up to four to five pairs of leaves were obtained with the use of Tabu + Albit preparations for seed treatment and Samurai Super insecticide for ground application. With the help of Celeste Top in combination with the studied fungicides, root rot was suppressed, while the prevalence of the disease was reduced by 24.4 and 24.8% compared with the absolute control. A high increase in the yield of stems was guaranteed by the treatment of plants with an insecticide and seeds with Celest Top preparations in combination with Albit and Benorad 2.19 and 2.10 t/ha.

The superiority in milk yield of the first heifers of the brown Swiss breed of Austrian breeding in all months of lactation over the peers of other groups has been established. At the same time, the lactation curves of imported heifers and their hybrids with local Shvits indicate that the maximum levels of productivity were observed in earlier periods – for 2-3 months lactation, whereas in individuals of the local population – for 3-4 months. After the peak of the productivity of the experimental livestock, the Austrian and crossbred Swiss heifers, whose lactation curve was relatively equalized, were the best preserved at the achieved milk yield level, while the local Swiss heifers had a sharp decline. The highest level of milk yield was distinguished by the first heifers of imported breeding, which surpassed both half-blooded peers (by 686 kg, P>0,999) and individuals of the local population (by 1656 kg, P>0,999). Imported animals, as well as crossbreeds, exceeded the yield of milk fat by 37,8-62,7 kg (P>0,999) and milk protein by 31,8–54,1 kg (P>0,999) of the peers of the brown Swiss breed of the local population.","PeriodicalId":219145,"journal":{"name":"The Agrarian Scientific Journal","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130269672","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 this regard, the purpose of the research is to select the optimal seeding rate and sowing method for white mustard, which increase the self-regulation of the number of weeds in the agrocenosis to obtain the highest seed yield. The experiment was carried out in 2020–2022 on the meadow-chernozem soil of the experimental plot of the Federal State Budgetary Educational Institution of Higher Education Penza State Agrarian University. The weather conditions during the years of research were different, but they met the requirements for the growth and development of white mustard. The growing season of mustard in the first and third years passed under conditions of sufficient moisture at the optimum temperature regime (HTC 1.3 and 1.0, respectively). In the second year of research, drier conditions developed, when the hydrothermal coefficient was 0.87. On average, the minimum infestation of mustard crops before harvesting was traced with an ordinary sowing method of 36-51 pcs/m2 with a wet weight of weeds of 75.8-106.0 g/m2, while with a wide-row method their number was 43-62 pcs/m2 with a mass of 91.0-129.2 g/m2, where the feeding area increased not only for cultivated, but also for weeds. Moreover, the agrocenosis was the cleanest with the maximum seeding rate (3 million germinating seeds/ha) and mustard sowing with a row spacing of 15 cm, where the vegetative mass actively suppressed weeds. The highest infestation in terms of quantity and weight of the weed component was established at a rate of 1.5 million and mustard sowing with a row spacing of 30 cm. Plants with row sowing with a seeding rate of 2.0-2.5 million germinating seeds/ha were more competitive, while providing a maximum oilseed yield of 2.46-2.58 t/ha.","PeriodicalId":219145,"journal":{"name":"The Agrarian Scientific Journal","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122281858","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}
