Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Plant Pathology V3 written by James G. Horsfall and published by Elsevier. This book was released on 2012-12-02 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Pathology: An Advanced Treatise, Volume III: The Diseased Population Epidemics and Control deals with the epidemics of the diseased population of plants and their forecasting and control. The book highlights the public health implications of plant pathology, giving major consideration to inoculum production, dispersal, and control. This volume is organized into 14 chapters and begins with an overview of populations of inoculum and the consequences of cultivation, emphasizing the inoculum potential. The next chapters focus on the autonomous dispersal of plant pathogens through the soil, seeds, or plant parts; the inoculum dispersal by animals, humans, air, and water; and the factors and processes that trigger an epidemic. The book also introduces the reader to the physical, chemical, and biological aspects of the performance of fungicides on plants and in soil, and then concludes by discussing the genetics of disease resistance and problems associated with plant breeding. This book is a valuable resource for those who are interested in a theoretical treatment of plant pathology and in the broad ecological relationships among organisms, as well as for research workers and advanced students of applied biology.

Download or read book Genetic Improvement of Vegetable Crops written by G. Kalloo and published by Newnes. This book was released on 2012-12-02 with total page 846 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic improvement has played a vital role in enhancing the yield potential of vegetable crops. There are numerous vegetable crops grown worldwide and variable degrees of research on genetics, breeding and biotechnology have been conducted on these crops. This book brings together the results of such research on crops grouped as alliums, crucifers, cucurbits, leaf crops, tropical underground and miscellaneous. Written by eminent specialists, each chapter concentrates on one crop and covers cytology, genetics, breeding objectives, germplasm resources, reproductive biology, selection breeding methods, heterosis and hybrid seed production, quality and processing attributes and technology. This unique collection will be of great value to students, scientists and vegetable breeders as it provides a reference guide on genetics, breeding and biotechnology of a wide range of vegetable crops.

Available in PDF, EPUB and Kindle. Book excerpt: Phytoplasma-associated diseases are a major limiting factor to quality and productivity of many ornamentals, horticultural and other economically important agriculture crops worldwide. Annual losses due to phytoplasma diseases in many crops vary, but under the pathogen favorable conditions they always lead to disastrous consequences to farming community. As there is no effective cure for phytoplasma diseases, the management options emphasize on their exclusion, minimizing their spread by insect vectors and propagation materials and on development of host plant resistance. The phytoplasma associated plant diseases have a history of more than 50 years. Phytoplasmas have undoubtedly infected plants and cause diseases for centuries before they are described and proven to be the causal agents. But important progress related to identification of phytoplasmas only began after 1980’s. Phytoplasmas have emerged as the most serious constraints in the production of several crops all around the world during last four decades. Phytoplasmas constitute a major limiting factor to quality and productivity of cereals, horticultural, ornamentals and many other economically important crops all over the world. Annual losses due to phytoplasma diseases may vary, but under the pathogen favorable condition, phytoplasma disease may lead to disastrous consequences for farming and industry community. The scientific literature concerning phytoplasma occurrence, characterization, diagnosis, detection, and management is growing at a fast pace. Significant advancement in the last decades on diagnostic, biological and molecular properties, epidemiology, host-pathogen-insect interactions as well as management of phytoplasmas has been made. Till date, no authentic compilation is available to know the progress of phytoplasmas characterization major crops all over the world. The planned book will compile all the updated information available information on phytoplasmas by distinguished experts in the form of edited book entitled “Characterization and epidemiology of phytoplasma associated diseases”. The book covers recent and update information on emerging and re-emerging phytoplasma diseases affecting important crops in tropics and subtropics. It provides comprehensive information on disease distribution, occurrence, and identification of the phytoplasmas including the recent approaches for diagnostics, transmission, and information about losses and geographical distribution along with and management aspects. This volume contains 11-12 chapters contributed by the experienced and recognized experts working on different group of phytoplasmas affecting major crops all over the world. The information on various topics is at advanced as well as comprehensive level and provides the period wise developments of phytoplasma research. The book covers major chapters on an up to date progress of phytoplasma research, and then phytoplasma diseases associated with vegetable, pulse, oils crops, cereals, sugar crops, fruit crops, ornamentals, medicinal plants, palms species, forest tress and weeds. We have covered historical background, geographical distribution, identification and characterization, genetic diversity, host pathogen interaction and management aspects of important phytoplasma diseases infecting our major agricultural crops. The information on various topics is advanced as well as comprehensive, and provides thought provoking ideas for planning novel research ideas for future. This book will be useful to everyone interested in mollicutes, phytoplasma, spiroplasmas, plant pathology, disease control and plant biology and serve as an exhaustive and up-to-date compendium of references on various aspects of different groups of phytoplasmas affecting important crops worldwide.
