The role of biostimulants in modern fruit tree and shrub cultivation

Abstract

Dynamic changes in the fruit tree and shrub cultivation sector caused, among other things, by a high increase in production costs, the European Green Deal and increasingly high requirements with regard to the quality parameters of the obtained yield and their safety for consumers force producers to continuously introduce new changes in cultivation technology in order to meet all requirements. Choosing the optimum cultivation technology is also crucial to the economic success of farmers, allowing them to continue to operate and grow. One of the fastest growing branches of crop support today is biostimulation. Although biostimulants are not essential for crop production, their use can be fundamental under certain conditions. The aim of this paper was to provide comprehensive information on research in the field of biostimulation of fruit trees and shrubs and to consider the potential use of such preparations in the perspective of maximising the use of fertilisers, plant protection products and improving the quality, structure and microbial life of soils and substrates. At the same time, obtaining the highest possible yield with the highest possible crop quality, fully safe for consumer consumption.
