Perspective Chapter: Effect of Organic Sources on Fruit Quality of Guava

Abstract

The organic tradition is the key to sound development of agriculture. The post green revolution era has lead to numerous challenges before the ecosystem, researchers and human health. Organic fruits are anticipated as higher nutritional content than conventionally grown fruits. The guava (Psidium guajava L.) is considered as potential, nutritional and important crop in India. It is well recognized for its medicinal values as it is rich source of antioxidants, secondary metabolites such as antimicrobial, antiviral and anti-inflammatory compounds. Guava fruits are employed for various cure viz., dysentery, diabetes, diarrehoea etc. Organic manures contains macro as well as micronutrients, plant growth promoting substances such as auxin, gibberellin and cytokinin. The positive response of combined application of different organic manures are proved by many researchers. The amendment of different organic manures in combinations can enhance the quality attributes and yield of guava fruits. At the same time, it is environment-friendly, sustaining soil fertility and productivity. The various fruit quality attributes viz., TSS, titrable acidity, sugar content, pectin content, ascorbic acid and TSS/Acidity ratio are discussed in this chapter.
