Sustainable production through biostimulants under fruit orchards

The world population is expected to be around 9 billion by 2050 which would be 34 per cent greater than the today’s population. This will enhance the food demand to match the rising population. Horticultural commodities in general and fruit in the particular has been designated as the source of nutraceuticals. For reaching up optimum level of production, Biostimulants may come up with and the emerging concept of to meet out with this challenge and over the last decade, utilization of natural plant biostimulants is gaining importance. The use of biostimulants can be extensively exploited under fruit crops as they contribute towards a crucial role in enhancing the anatomical, morphological, physiological, that ultimately ameliorated the fruit productivity, and quality of the fruits. In addition, the application of biostimulants helps in promoting physiological actions like photosynthesis, nutrients metabolism, enzymatic activities, chlorophyll, protein and carbohydrate content. It also helps to mitigate abiotic stress like water stress, salinity, temperature, and changes related to oxidation–reduction reaction, reactive oxygen species detoxification, stress signaling, and hormonal pathways. After much exploration regarding the effects of biostimulants on fruit crops, there is still a void that exists in the area related to its impact on various traits. Henceforth, an appropriate tactics approach is much needed under the areas of research about biostimulants. Graphical Abstract
