Abstract

The article presents the results of research on the effect of the Trevitan® composite recultivator on the elemental composition and ratio of macroelements in the fruits of the F1 Talent edible hybrid tomato. Field experiments with edible tomato were carried out in the conditions of the Western Forest Steppe of Ukraine on meadow-chernozem medium loam soils in 2021. The soil of the experimental field was characterized by a neutral reaction (pH=7,12), a low content of mobile compounds of macronutrients, and of trace elements (Fe, Mn, Cu, Zn). In the studies, Trevitan® composite recultivator was used – a product of organic origin for rapid soil regeneration, processing of seeds and planting material of various agricultural crops, acceleration of plant growth and development. Trevitan® is a liquid with a pH=7.5-10.9 and a mass fraction of organic matter of 50-80 % on the dry substance of the preparation. Trevitan® was applied by autumn soil treatment before plowing, seed and plant treatment during the growing season. 
 The use of Trevitan® compound recultivator in the technology of growing the Talent hybrid tomato influenced the indicators of the content of macro- and microelements, mainly by increasing their content. The content of Nitrogen, Potassium and Magnesium in the fruits of experimental plants compared to the control increased by 21,0, 31,6 and 43,3%, respectively. The amount of nitrogen in the fruits did not exceed the permissible level, which is an important characteristic of the quality of the fruits. It has been established that the use of Trevitan® composite recultivator helps to improve the mineral composition and biological value of tomato fruits, to increase the content of Manganese, Copper, Zinc and Potassium in them, while optimizing nutrition in the soil-plant system.
