The role of grafting in the productivity of tomato of extended cycle

Abstract

Relevance. The purpose of the research: to study the effect of technological method (grafting) on tomatos productivity in the conditions of protected soil in the Tyumen region. Research objectives: based on the study of tomato rootstocks for the studied graft, to identify the most productive rootstock for subsequent use in LLC “Greenhouse facility “TyumenAgro” . Subject of research: protected ground conditions.The object of research: tomato hybrids F1 Maxeza, F1 Trovanzo and F1 Complis (as grafts), F1 Maxifort and F1 Emperador (as a rootstocks). The article also provides information on the use of the technological method of grafting when growing tomatoes in protected soil conditions in LLC “Greenhouse facility “TyumenAgro””.Methods. The productivity of tomatoes is taken into account from1 m2 in three-fold repetition. Crop accounting is carried out separately for each option as the fruit ripens, after 5–7 days. The results of crop accounting are processed by the method of variance analysis presented by B.A. Dospekhov. Results. In the course of research, it was found that the cultivation of tomato hybrids in conditions of lowvolume hydroponics, subject to phytosanitary measures, allows to increase the yield and quality of fruits. The highest yield for the crop cycle of 2018–2021 was observed in plants with Maxesa F1 graft and Emperador F1 rootstock, it amounted to 226.47 kg/m2. Based on the research, elements of a new technology will be proposed, characterized by significantly higher quality indicators of tomato productivity formation.
