Evaluation of the Content of Macro- and Microelements in the Leaves of Garden Strawberry (fragaria Ananassa Duch.) Under Different Mineral Nutrition Systems

Abstract: The use of mineral fertilizers is a necessary practice that contributes to realizing the yield potential of crops. However, the efficiency of nutrient utilization by plants remains low, which can lead to non-productive losses and negative environmental consequences. One of the possible solutions is the use of fertilizers of prolonged action, including modern Russian developments in the field of polymer-modified fertilizers (PMFs). In this work we evaluated the changes in the content of a number of elements (Ca, P, K, Mg, Cu, Zn, Mn, Fe) in the leaves of strawberry (Fragaria ananassa Duch.) cultivars Elizaveta-2, Profusion, Irma under the conditions of different nutrition systems – without fertilizers, with the application of traditional mineral fertilizers, the author's system with the use of PMF (with a polymer content of 5% and 10%) and with the use of a foreign analog of PMF. Strawberry plants were grown under greenhouse conditions, and leaf samples were taken at three vegetative stages – the stage of formation of white fruits, the stage of beginning of fruit ripening, and the stage of ripe fruits. Elemental analysis of the leaves was performed by inductively coupled plasma optical emission spectrometry (ICP-OES). Differences between strawberry cultivars and between nutrition systems for plants of the same cultivar were found. At the same time, according to the results of the evaluation of the changes in the content of a number of macro- and microelements in the leaves of strawberry plants at different stages of vegetation under different nutrition systems, no striking regularities were observed that would be characteristic of each variety used in the experiment. However, the increase in the content of Ca, Mg, Cu and Fe observed in a number of cases when using the author's nutrition system may indicate the improvement in the conditions for the uptake of these nutritional elements when using PMF.
