“…However, fertilizers' introduction into the soil cannot always provide a sufficiently reliable effect due to the varying availability of elements, environmental conditions, delayed manifestation of fertilizers' effect on perennial crops. Mineral elements supplied with fertilizers take part in the formation of chemical indicators' complex of fruit quality [15][16][17][18][19].…”

The results of a five-year study of the mineral fertilizers' effect on the chemical composition of Venyaminovskoe apple cultivar fruits are presented. It is shown that the use of soil and foliar application of nitrogen and potash fertilizers did not have a significant effect on the content of soluble solids, sugars, titrated acids, ascorbic acid, and phenolic compounds in fruits. It was established that the most significant factor affecting the chemical composition of fruits are the weather conditions of the growing season. At the same time, the content of ascorbic acid significantly exceeding the control over an average of five experimental years was found in the option with the introduction of nitrogen and potash fertilizers into the soil at a dose of N60K80 together with foliar top dressing. There is a tendency of increasing accumulation of leucoanthocyanins in fruits over the years. In 2021, there was a significant decrease in catechins with the use of mineral fertilizers at a dose of N60K80, as well as in the following options: without soil and minimal (N30K40) fertilization against the background of top dressing.

“…For apple orchards grown in the climatic conditions of the Central Russian Upland, a significant effect of meteorological conditions and tree productivity on the level of mineral forms of nitrogen in the soil has been shown [11,12]. The same factors have a significant impact on the Nmin dynamics in the soil of young sour cherry orchards entering fruiting [13,14].…”

The aim of the investigation was to research the mineral nitrogen (Nmin) behavior in loamy haplic Luvisols of orchards located in the forest-steppe zone of the Central Russian Upland. The seasonal dynamics of N min (ammonium + nitrates) was studied during the growing seasons of 2018 and 2019 in field experiments with apple and sour cherry. Fertilizers were applied annually in spring at doses increasing from N30K40 to N120K160. The most important factors influencing the nitrogen dynamics were meteorological conditions, productivity of trees, peculiarities of nitrogen uptake by the studied crops. Fertilization of orchards with nitrogen contributed to an increase in Nmin content by 1.5 … 5 times, depending on the dose. The dynamics of Nmin in the soil of fertilized and unfertilized plots was similar and depended on the biological features of the crops: the lowest indicator’s level in the soil under sour cherry was in July during fruit ripening, while in the apple orchard a low nitrogen content was noted in August. Studies have shown that in the climatic conditions of the Central Russian Uplands, loamy haplic Luvisols without additional application of nitrogen fertilizers can provide a favorable level of nitrogen nutrition for apple and sour cherry trees in the first years of fruiting.

“…Te mineral composition of fruit crops afects fruits' quality and technological indicators, including their shelf-life capacity. One of the critical problems in ensuring the high quality of products and their safety is providing the optimal calcium content in fruits and berries [25][26][27].…”

“…Calcium is a critical component in maintaining the hardness of fruits during storage, as it is responsible for the integrity of the cell [25,26]. Calcium ions create compounds between the peptic molecules in the middle of the plate, which are responsible for the integrity of the cell [25][26][27]. For instance, it was confrmed that apple fruits with a content of Ca >5 mg/100 g f.w., with a ratio (K + Mg)/Ca <25 mg/100 g f. w. and Ca/Mg >1 mg/100 g f. w. have high resistance to diseases during storage [27,28].…”

Tus, the softening of the fruit may result from the loss of calcium in the middle of the plate and/or its absence in the bonds between the peptic molecules [28].…”

Foliar calcium (Ca) treatment exhibits strong potential for enhancing yield and quality in some fruit crops. This study aimed to assess the impact of foliar application of Ca-organomineral (Ca-OM) suspension on total soluble solids (TSS) and Ca dynamics in leaves and berries across five red currant cultivars during the vegetation and storage. A randomized block design with two treatments: (1) Control (without Ca-OM treatment) and (2) foliar Ca-OM treatment, with three repetitions, was applied on five different red currant cultivars. Although foliar Ca-OM treatments did not impact Ca or TSS in leaves, they positively influenced Ca and TSS in fruits, displaying significant variability among cultivars. In addition, Ca-OM treatment increased berry density, reduced abscission, and inhibited the development of diseases, extending storage periods for “Lvovyanka,” “Vika,” and “Gazel” cultivars by three to seven days compared to the Ca-OM untreated control. Ca-OM treatment in the early stages of the ontogenesis of currants provided a high percentage of Ca intake in berries. At the stage of complete maturation, the Ca content in berries decreased and depended on the ripening period of the cultivars. Before harvesting, Ca-OM increased the strength of berries (Fc) and reduced the shedding of berries in the clusters (Fs). At the vegetation stage, Ca-OM increased TSS in berries, and the content of TSS depended on the genotype and weather conditions. The Ca-OM treatment and low temperatures contributed to preserving berry density, reducing the shedding of berries and PLW, and restraining the development of diseases during storage. In addition, the high content of TSS and Ca in berries against the background of a slow rate of decrease in berry density in the Ca-OM variants ensured an extension of the shelf life of “Lvovyanka,” “Vika,” and “Gazel” by three to seven days compared to the control untreated with Ca-OM. Clustering analyses identified these cultivars as similar in terms of TSS and calcium content in fruits, emphasizing their common traits. The study underscores the potential of foliar Ca treatment to enhance berry quality during growth and storage, significantly improve storage duration, and fortify resistance against adverse factors, presenting promising opportunities for elevating yield and quality in specific red currant cultivars.
