The study was conducted in the conditions of the economy of LLC “Flame” of the Korablinsky district of the Ryazan region, in 2021–2023. Clearfield is a universal production system currently used worldwide, which involves the use of modern high-yielding hybrids resistant to selective herbicide. A single application of herbicides of this system allows you to create a soil herbicide screen that restrains subsequent waves of weeds. The conducted studies allowed us to establish that the post-emergence use of herbicides in combination with an adhesive in oilseed crops destroyed 100% annual dicotyledonous weeds such as the common mountaineer, rough mountaineer. Cultivation of rapeseed and sunflower using Clearfield technology provided clean crops of these crops, and additional foliar treatment of plants with fertilizers created favorable conditions for additional formation of elements of the crop structure. The maximum yield of spring rapeseed over the years of research was recorded on the Lebozol-RAPSMIX variant of 21.4–24.2 c/ha (winter wheat) and 21.9-26.3           (spring wheat), the excess relative to the untreated variant was 21.7 % (+4.2 c/ha) and 25.7 % (+5.0 c/ha), respectively.

Resistance to lodging (RL) of samples in years with contrasting heat and moisture conditions may also have different estimates. In this connection, the purpose of the research was to identify the dependence of plant height and resistance to lodging of peas on the hydrothermal coefficient (HTC) of the growing season. The research was carried out in 2019 2023 in the forest-steppe of the Krasnoyarsk Territory, in the competitive variety testing nursery of the pea breeding laboratory of the Krasnoyarsk Research Institute of Agriculture. The soil of the site is represented by ordinary chernozem of medium thickness, medium humus with neutral acidity. For the study, 8 samples of selfselected peas were taken. Samples were arranged in a systematic manner in quadruplicate, the plot area being 15 m2. During the research, it was revealed that in order to objectively characterize pea samples by stem length and its resistance to lodging, it is necessary to take into account the HTC of the growing season, since the differences between the lengths of plants in years of different HTC of the growing season can change by 2 times. The length of plants depended significantly on the hydrothermal coefficient of the growing season; separately for the months of the growing season, it was revealed that the strongest direct correlation is typical for August r ± Sr = 0.88 ± 0.08. The maximum lodging of samples was noted during an excessively humid growing season, the minimum during a dry one, the difference in the assessment could reach one point. An increase in HTC had the maximum effect on reducing the resistance to lodging of semi-dwarf samples and the entire sample; medium-sized samples showed an average degree of dependence. When analyzed by month of the growing season, the greatest influence on the decrease in plant resistance to lodging had the August HTC r ± Sr = -0.95 ± 0.18, p = -0.75.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":"65 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141663386","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 research was carried out in a field of fallow and grain crops in a five–field field crop rotation (fallow – wheat – rapeseed – barley – oats). The experimental design included basic tillage techniques: 1 – moldboard tillage to a depth of 20–22 cm; 2 – minimal processing (disc peeling to a depth of 10–12 cm); 3 – zero tillage (direct sowing on the stubble of the predecessor). It was shown that ordinary chernozem of the Krasnoyarsk forest–steppe under the conditions of basic cultivation was characterized by a loose and normal composition of the 0–20 cm layer with a seasonal rhythm not exceeding 18 %. The density of the 0–20 cm layer of chernozem depended 19–28 % on the nature of the agrocenosis. This influence is most pronounced in the 10–20 cm layer (26–37 %). Crop rotation fields according to the density of the crop on all backgrounds of the main cultivation were located in the following increasing series: fallow (0.90–0.96 g/ cm3) – wheat (0.95–1.02 g/cm3) – barley (0.97–1.00 g/cm3) – oats (0.98–1.05 g/cm3). It was established that the cultivation of agricultural crops and fallowing the field against the background of moldboard plowing formed a density at the level of 0.94–0.98 g/cm3. Tilling the soil with a discor in crops of grain crops increased the soil density to 0.97–1.01 g/cm3; zero sowing – up to 1.00–1.05 g/cm3.

According to the research results, technologies for growing promising crops (eastern goat, variable alfalfa, festulolium, reed fescue) in single-species and mixed crops have been developed. Bloodless crops of goat and grass mixtures for two mowing ensured the production of 7.2–7.9 t / ha of dry matter. In terms of productivity, single-species crops significantly exceeded mixed crops. From grass mixtures, stand out crops with meadow fescue, hedgehog and awnless rump stood out. The yield of variable alfalfa and grass mixtures with its participation for two mowing ranged from 7.8 to 9.5 t/ ha of dry matter. Significantly inferior to alfalfa by 0.86–1.04 t/ha of dry matter were grass mixtures with timofeevka. Single-species festulolium crops with two-mowing use were significantly inferior in yield to grass mixtures with leguminous grass species by 0.9-4.0 t/ha of SV. Legume-cereal grass mixtures were characterized by an increased protein content (1.7–2.1 times), fat (1.1–1.2 times), reduced fiber (1.2–1.3 times). Harvesting of the first mowing during the budding phase of legumes, the beginning of earing of the festulolium significantly reduced the yield of dry matter by 20% compared with harvesting during the flowering phase. At the same time, the protein content in the plant mass of early mowing increased by 12 % in festulolium, by 21–36 % in festulolium with clover and birdʼsfoot trefoil, and by 3–11 % in herbage with alfalfa.

A total of 165 species of vascular plants have been identified, of which 3 species form a stand, 26 species of undergrowth, and 136 species of living ground cover. 39 synanthropic plant species (23.6 % of the total flora) were found in the lower tiers of the forest, including 14 anthropophytic species in the undergrowth, 5 anthropophytic and 20 apophytic species in the living ground cover. A richer floral composition is characteristic of the grass forest type, compared with the fresh forest type, which is associated with different forest growing conditions. Anthropogenic factors lead to an increase in the species composition of pine plantations near the city limits – more intensively in the grass forest (r = -0.74), less intensively in the fresh forest (r = -0.39). As we move away from the city limits, the ratio of ecological and cenotic components changes in pine plantations: the share of the forest component increases, the share of the synanthropic component decreases. Among the synanthropic plants of the lower tiers, aggressive species (Malus baccata (L.) Borkh., Acer negundo L.) are noted, which strongly transform the forest environment, preventing the renewal of the main breed. The value of the index of synanthropization of the species composition of pine plantations varies with distance from the city limits: 0,28–0,29 – 0–4 km; 0,12–0,20 – 4–11 km; 0,03–0,07 – 15–43 km, therefore, the forest fund of the forestry can be divided into 3 zones – high, moderate and weak anthropogenic transformation.
