“…Qualitative indicators of vegetable raw materials are determined by many factors such as the zone of growth and agrotechnical methods of cultivation (Postnikov et al, 2021;Yakovenko et al, 2020;Firdous and Subhash, 2017;Kumar et al, 2017;Rani and Latha, 2017). When studying the mineral composition of apple fruits, a database was formed for more than 500 samples according to the level of accumulation of magnesium cations depending on the phase of fruit development -fruit size of 8-12 mm, 40 days before ripening and removable maturity (Prichko et al, 2019).…”

Background: Present study on determining the region of origin of raw materials, the authenticity of organic food products is relevant. The determination of the natural content of stable isotopes are not able to answer these questions. The solution can be obtained by studying the ratios and fractionation of stable isotopes, which provide information on the transformations of chemical elements in biological, ecological and geochemical studies. Methods: During 2020-2021 obtained data on the content of magnesium isotopes in apple fruits of 14 varieties from three growing regions of the Russian Federation. Previously, over 10 years, a database was formed of more than 500 samples on the level of potassium, calcium, magnesium, phosphorus and nitrogen cations, depending on the variety and phase of fruit development. Result: Research presents the results of determining the natural content of stable magnesium isotopes in apples, the isotopic composition and their fixation, depending on different regions of the growth of raw materials. The isotopic composition of apples (26Mg/24Mg) varies from 0.1669047 to 0.1782649; the deviation of the magnesium isotopic composition from the conventional standard varies within 25.52-43.52; their chemical fractionation has value: in Central Zone of Russia-185.2-212.3; South of Russia-248.0-311.5; North Caucasus-182.7-214.8.

“…Загальний винос NPK у розрахунку на створення однієї тони плодів груші становить, відповідно, 1,75, 0,76 і 2,51 кг, тимчасом яблуні -1,46, 0,48 і 1,79 кг за рівного врожаю плодів. Насадження груші забирає з ґрунту більше елементів живлення, особливо калію, від якого залежить якість генеративних бруньок, розміри плодів, їх колір та смак [8]. Це підтверджується дослідженнями, проведеними в різних ґрунтово-кліматичних умовах [9][10][11].…”

Modern technologies of cultivation of seed crops plantations imply high efciency of fruit production while optimizing mineral nutrition of trees. The aim of the research is to increase fruit yield and economic efciency under optimized fertilization of pear trees in a re-growing rain-fed plantation. The results of the research, carried out to study the effect of optimized fertilization on yield capacity, fruit quality and economic efciency of replant pear-tree cultivation, cultivars Conference and Osnovianska (on vegetative rootstock quince A) in different age periods of growth and fruiting, were considered. Based on the results of agro-chemical analyses, the rates of nitrogen and potassium fertilizers were calculated in the way to compensate the lack of N–NO3 (by a nitrifcation ability of the soil) and forms of K2O, available for plant nutrition, and to make their content equal to optimal levels, scientifcally established for apple-tree and recommended for pear-tree plantations. It was found out that the highest yield capacity of the studied pear-trees was recorded with additional application of nitrogen and nitrogen-potassium fertilizers (background+N30, background+N30K30); it was higher by 27.2 and 36.7, 29.8 and 36.1 %, respectively, as compared with the yield capacity of unfertilized trees, and it was higher by 0.6 and 2.6, 4.7 and 4.2 % for the fertilized trees with the annual application of N90 P60K90 (production control); there the correlation of nitrogen, phosphorus and potassium of plant nutrition was less balanced, the total amount of fertilizers was larger though. Fertilization is a leading factor in the formation of the proftability of pear-tree agrocenosis. The use of various cultivars and practices to apply fertilizers in pear-tree plantations has an impact on the economic indicators of fruit production in diﬀerent age periods of growth and fruiting. Key words: pear-tree, varieties, fertilization, yield capacity, marketable quality, revenue, proftability.

“…In these conditions, with low initial yield capacity, no return on investment, made when the orchard was planted, takes place. Hence, more and more attention is paid to the overcoming of replant disease both in scientific research and production sphere (Yakovenko and Melnyk, 2015;Melnyk and Yakovenko;2017;Henfrey and Baab, 2013;Wiedmer and Thalheimer, 2013;Moroz, 1990;Yakovenko et al, 2020). The necessity to re-plant new industrial fruit plantations on the site of the uprooted old ones predetermines a more detailed studying of replant disease and the ways to overcome it or at least reduce its negative effect on young newly planted plants.…”

Background: It is expedient to reduce or remove a negative effect of replant disease on new plantations after the old uprooted ones. To solve this problem, it is necessary to carry out the direct researches aimed at identifying the reasons for a negative effect of toxic soil conditions on young fruit plantations. Methods: A vegetative trial, aimed at studying the effect of replant disease on the planted young apple trees after the uprooting of a 34-year-old apple plantation which was grown on the plots after a 50-year-old experimental orchard with apple fertilization systems, was established in spring of 2019. Result: It has been found out in a vegetative trial that the growth of young apple trees weakens considerably in the first two years after planting one-year-old trees. The neutralization of replant disease, when dark grey opodzolic heavy loam soil was fertilized with manure, took place due to enriching it with organic substances. As a result, all the indicators of soil fertility increased and different bio-toxic compounds, which had a negative effect on mineral nutrition of young fruit plants, on their growth process and fruiting, neutralized faster and more intensively.
