Abstract
In recent days, several technological innovations were proposed in order to improve the production and sustainability through a significant reduction in use of agrochemicals. One 0f the best approach to increase crop productivity is the utilisation of environment-friendly organic products such as “Biostimulants”. There are different types of substances that act as biostimulants namely humic and fulvic acid, protein hydrolysates and other N-containing compounds, Seaweed extract and botanicals, Chitosan and other biopolymers, Inorganic compounds, beneficial fungi and bacteria. These biostimulants plays an important role in improving the plant growth, yield and quality of the product. The guava fruits coated with chitosan 1% and stored at 12°C had shown higher firmness, TSS, titratable acidity and maintained greenness with a slow increase in yellow colour by the end of storage. Knowledge on effective use of these biostimulants by understanding their properties has become a challenge to the researchers to improve yield, quality and shelf life of different horticultural products.
