The art of topiary requires a well-thought-out compositional integrity. Before choosing plants, you should decide on the theme of the garden and the harmonious arrangement of topiary figures in it. Such compositions become an adornment of any backyard territory, giving it an aristocratic exclusivity and originality. A detailed taxonomic analysis of the assortment of plants, which were used to form topiary on the territory of Vinnytsia National Agrarian University and the botanical garden \"Podillya\", was carried out. The state of the existing topiary figures was assessed. The features of the formation of topiary figures by the classical and wireframe formation technique have been investigated. Of the plants of the classical formation technique, a spiral figure has an excellent appearance. The hedge, cone and column shape have a good appearance. Plants formed in the form of a circle have the lowest indicators of external perception. The frame technique for creating plant compositions prevails at the VNAU exposition area. Project proposals have been developed to improve the aesthetics and general appearance of topiary figures on the territory of the Vinnytsia National Agrarian University. For the plant to have an attractive appearance, appropriate care is needed. Pruning of plants (sanitary) should be carried out only during the dormant period. The best period will be the end of winter, when the threat of severe frosts has passed. In the spring, no later than the first half of April, the first corrective pruning of figures and hedges should be carried out. In the summer, several additional haircuts are made, the frequency of which depends on the intensity of growth. It is optimal to carry out an additional haircut 3 months after the first one. In summer, you do not need to cut in extreme heat. Haircuts are finished before the onset of the first frost. If you carry out the formation later, then the created topiary will simply freeze over. In the cold season, some figures, especially those created from conifers, can fall apart under the weight of snow, so it is advisable to tie them up.","PeriodicalId":7511,"journal":{"name":"Agriculture and Forestry","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81867118","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}

Two hybrids of early-ripening sunflower maturity Integral and Slavson were studied in the studies of row spacing and sowing density. To achieve this goal used field, laboratory, statistical and computational methods. The quality of the harvest and its structure, the efficiency of the use of environmental resources were determined by the laboratory method. The reliability of the obtained research results was assessed by a statistical method. The economic efficiency of the studied elements of the technology was determined by the calculation-comparative method.

The best conditions for growth and development of sunflower plants were created in the variant where the mouldboard tillage was carried out with a plow PLN-3-35 to a\u0000depth of 23-25 cm and the whole period the cultivated plants were without competition from weeds for life factors - SI Arko - 143 cm, Alcantara - 158 cm and NC Brio - 177 cm.

The height of plants in the early-ripening hybrid of sunflower SI Arco in 2021 ranged from 122-143 cm, middle-early Alcantara - 142-158 cm and medium-ripe NK Brio - 160-177 cm, i.e. was the highest. Shallow and surface tillage with disc implements increases vegetative weeds by 2.3 and 2.8 times, respectively. The implementation of protective mechanized measures for sunflower sowing against weeds has contributed to a significant reduction in their number.
