Book Description
Physiological or abiotic disorders are mainly caused by changing environmental conditions such as temperature, moisture, unbalanced soil nutrients, inadequate or excess of certain soil minerals, extremes of soil pH and poor drainage. The distinction between physiological or abiotic disorders from other disorders is that they are not caused by living organisms (viruses, bacteria, fungi, insects, etc.), but they are the result of abiotic situations (inanimate) i.e. their agents are non-living in nature which causes deviation from normal growth. They results in physical or chemical changes in a plant which is far away from what is normal and is generally caused by an external factor. Non-infectious disorders in some cases are easy to identify, but others are difficult or even impossible to recognize. Most of them are non reversible once they have occurred. For the identification of physiological disorders it is important that one must know that: a) Physiological disorders are often caused by the deficiency or excess of something that supports life or by the presence of something that interferes with life. b) Physiological disorders can affect plants in all stages of their development. c) They are non-transmissible because they occur without or in absence of infectious agents. d) Plant reacts differently to the same agent and sometimes response is seen as a little reaction to death. e) Dealing with physiological disorders often means dealing with the consequences from a past event. f) Generally damaged and undamaged tissue is clearly demarcated. g) Physiological disorders not only causes damage themselves but also serve as the 'open door' (entry) for pathogens.

Book Description
Among the Horticultural Crops, Fruits and Vegetables (FV) are of primary - portance as the key source of essential components in an adequate and balanced human diet. FV have supported largely the daily food requirement of mankind since ages and even before man learned to grow cereal crops systematically. Over the years, growing FV has been the mainstay of rural economy and has emerged as an indispensable part of agriculture world over, offering farmers a wide range of crops in varied topography and climate. In certain parts of the world, FV are the major dietary staple. Apart from being a rich source of vitamins and minerals, this sector also contributes significantly in economy of the region or the nation. The increased income from per unit area of FV is far ahead and can not be compared with that of cereal crops. A recent survey by the Economist revealed that the world population has - creased by 90 % in the past 40 years while food production has increased only by 25 % per head. With an additional 1. 5 billion mouth to feed by 2020, farmers worldwide have to produce 39 % more. Looking at the load of the future food requirement, the global increased production of FV during last few years has absorbed the additional food requirement and accordingly the eating habits are also changing and shifting - wards more consumption of these commodities worldwide.

Book Description
Diagnosis involves careful observation of crop with a thorough knowledge of crop behaviour as well as a complete understanding of functions of nutrients and their deficiency symptoms. Diagnostic techniques vary from crop to crop depending upon the field condition in which the deficiency occurs. Indian agriculture has entered into an era of multiple nutrient deficiencies. Realizing the gravity of emerging problem of nutrient deficiencies and to fulfill an immediate need to tackle them more efficiently, a guide on diagnosis of nutritional disorders and their corrections in crop plants has been prepared. All the new diagnostic techniques have been discussed in a simple language. The book has been designed in such a way as to improve the knowledge on diagnosis of deficiencies of mineral elements essential for normal plant growth, and of the methods by which such deficiencies may most effectively be remedied. The main feature of this book is the detailed description of the various visual deficiency symptoms exhibited by the fruit crops. The book has been written primarily for the use of the students of Horticulture and Agriculture to help uate their knowledge on nutritional and physiological disorders of fruit crops. It is also felt that the book will provide a suitable basis for those engaged in the profession of agriculture like extension workers and progressive farmers. We hope that this book will go a long way to help in increased fruit production by proper diagnosis and suitable correction of nutritional disorders in fruit crops.
