Plant nutrition and physiological disorders in fruit crops

Abstract Citrus fruit like other fruit crops (mango, banana, grape, papaya, litchi, loquat, etc.) is prone to different physiological disorders, which decrease its fresh market value and cause economic losses worldwide. In general, these disorders arise due to nonpathogenic factors such as adverse environment conditions, nutrient constraints, chemicals, and some genetic factors, which result in abnormal external or internal conditions and abnormal growth pattern of fruits. In this chapter, special emphasis has been put on not only the causes of physiological disorders but also the management approaches to retain the high quality for higher market value by preventing these disorders.
