In this regard, improving technological methods for cultivating such a crop as zucchini (Cucurbita pepo L.) is of scientific and practical importance.   Materials and Methods. The research was carried out on the territory of a private farm in the village of Chukhny, Smorgon district. Field and laboratory studies were carried out using generally accepted methods and guidelines.   Results. Substantiated the feasibility of cultivating green manure crops in combination with the local application of thermoammonia-disinfected compost when growing zucchini in seedlings on sod-podzolic light loamy soils in the natural climatic conditions of Belarus. The developed technological methods ensure the reproduction of soil fertility, increased yield, and production of high quality products without the use of mineral fertilizers. When using green manure and disinfected compost, the nitrate content in zucchini cv. Bonus, grown without mineral fertilizers, was in the range of 280-320 mg/kg. To reproduce the fertility of soddy-podzolic light loamy soils when growing zucchini in the natural climatic conditions of Belarus, it is advisable to use oats, oilseed radish and peas as green manure fertilizers. This technological technique increases the content of organic matter in the soil by 0.8-1.3 %. Together with green manure, adding thermo-ammonia-disinfected compost into a hole when planting zucchini seedlings ensures an increase in organic matter content by 1.2-1.5 % in the compost localization zone. During the decomposition of organic matter of green manure crops and disinfected compost applied locally, nutrients are released in quantities sufficient to form a high yield of zucchini with a nitrate content below the maximum permissible concentration. Thus, when grown on soddy-podzolic light loamy soils in the natural climatic conditions of Belarus, the proposed technological methods make it possible to obtain high-quality products and significantly increase the yield of zucchini due to green manure in combination with the local application of disinfected compost without the use of mineral fertilizers.","PeriodicalId":23570,"journal":{"name":"Vegetable crops of Russia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140374472","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}

Today everbearing (remontant) strawberry varieties gain in popularity due to their long fruiting period, and high yield and berry quality. Annually new foreign varieties appear on the Russian market. For this reason, it is important to study foreign garden strawberry varieties of different ecological and geographical origin and identify those of them that are adaptable to agro-climatic conditions of a given region.   The research goal was to determine the biochemical and customer qualities of the garden strawberry varieties introduced in Primorsky kray and to select varieties with economically important traits for further breeding and production.   Research methods. The research was carried out in the nursery of primary variety testing at FSBSI “FSC of Agricultural Biotechnology of the Far East named after A.K. Chaiki”. The following garden strawberry varieties of foreign breeding origin were used as the research object: Сabrillo (USA), Albion (USA), Florentina (Netherlands), Murano (Italy), and Bravura (Netherlands). The studied varieties were day-neutral and everbearing. Variety Elizaveta 2 was used as the control (Russian breeding origin; admitted to use in all regions of the Russian Federation). The following parameters were evaluated: total yield, average berry weight, maximum berry weight, berry size, the yield of marketable berries, and the content of dry matter, reduced sugars, and vitamin C. The accumulation of anthocyanins in berries was determined by a rapid assessment using a color scale. Records were made and scientific observations were conducted according to “Program and methods of variety testing of fruit, berry, and nut crops” (1999).   Results. Based on the results of the research on the economically important traits of the everbearing day-neutral strawberry varieties introduced in Primorsky kray, the following varieties were selected: Cabrillo for yield (263.3 g/plant, control – 82.8 g/plant), Murano for the yield of marketable berries (81.3 %), and Bravura (15.5 g) and Florentina (15.2 g) for berry size. The highest content of dry matter was accumulated in berries of variety Аlbion (9.87%). The highest content of reduced sugars was found in varieties Cabrillo (7.16%), Florentina (7.09 %), and Аlbion (7.09 %); of vitamin C – in Florentina (60.30 mg/100 g), and of anthocyanins – in Murano (50 mg/100 g). Murano was established to be the most promising variety under the conditions of Primorky kray for the complex of its traits.","PeriodicalId":23570,"journal":{"name":"Vegetable crops of Russia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140379628","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}
