Available in PDF, EPUB and Kindle. Book excerpt: Weed infestations are a concern for every farmer . Depending on the type of rice production system, farmers across Asia often contend with the same or similar weed species. This group of species is relatively small, but of great importance, and includes many of the "world's worst weeds." In this guide, we have tried to collect practical information about some of the most common weeds of rice in Asia. The guide contains information about the botany, ecology, herbicide resistance, and cultural control of these species in a short text that should be easy to use in the field. In addition, it includes pictures to aid in early and accurate species identification.

Book excerpt: Responsible for a high proportion of the world's crop losses, weedstake away food that the world badly needs. They decrease thequality and quantity of vegetable fibers, wool, and hides, andinterfere with fishing, irrigation, hydroelectric power production,and the movement of shipping vessels. In order to recognize thetrue magnitude of the weed problem, and to be better equipped todesign effective weed control methods, it is vital to identify andlearn as much as possible about the many different species of thisdestructive agricultural predator. The culmination of four decades of global research, World Weedspresents comprehensive and up-to-date information on over 100weeds--addressing recent changes in such areas as crop tillagemethods, herbicide use, and agricultural runoff. This monumentalwork, featuring a wealth of original data from the authors,provides extensive coverage of the known biology of each species.Each entry contains a full botanical description, plus importantdetails on habitat requirements and distribution, seed production,ecology, physiology, crop impact, and more. Generously suppliedwith dozens of unique illustrations and species distribution mapscovering over 100 countries, this definitive resource boasts anextensive multilingual index of common names, and a massivebibliography with over 3,000 references to facilitate furtherreading and research. World Weeds is a truly masterful referencethat will be celebrated by weed and crop scientists, botanists, andothers for years to come.

Download or read book Diversity of Rice Weeds Vegetation and Its Potential as Local Forage written by Bergmeier Erwin and published by LAP Lambert Academic Publishing. This book was released on 2015-06-16 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high variation in the diversity of weed was found across the studied paddy field types. Mid-elevation paddy field is highly diverse in weeds than lowland paddy field. Results show that altitude as well as water availability may support species richness. Poaceae, followed by Asteraceae, were most common. Some effects differed between regions correlated with different agricultural management, such as weeding habits, plant cropping and cultivation time. However, environment complexity by semi natural vegetation did not influence weed number in paddy fields. Accordingly, weed biomass and nutrient content, thereby abundance of rice weeds has considerable potential as ruminant feed. Consequently, to conserve and support species diversity and ecological function in paddy field and farming system, we suggest to enhance the integrated farming system included animal husbandry. Further, varied condition of semi natural vegetation, fallows and bunds should maintain to support plant diversity and ecosystem functioning in paddy field.

Download or read book Ecology of Java Bali written by Anthony J. Whitten and published by Tuttle Publishing. This book was released on 2013-02-05 with total page 868 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ecology of Java and Bali is a comprehensive ecological survey of two of the most ecologically diverse islands in the Pacific. It also contains the results of original research, interviews and personal experience. It will be useful to resource managers, ecologists and government planners, as well as to all others interested in the region. Java and Bali are the best known of all the islands in the Indonesian archipelago. Nowhere else in the country are ecological issues of such importance, and nowhere else is there a better chance of the major development problems being solved. This is because Java has the greatest concentration of development projects, the densest population, excellent human resources, and the interest of many of the most powerful decision makers. Bali, meanwhile, has the eyes of the world on it as an important tourist destination enjoyed by both domestic and foreign visitors.

Download or read book Pest Management in Rice written by L.G. Copping and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: The four-day international Conference on Pest Management in Rice, which is the subject of this volume, was the third in an ongoing series of meetings on tropical crops organised by the Pesticides Group of the Society of Chemical Industry, London. The participants came from both the public and private sectors and from many different countries. All the major groups of pests-weeds, microorganisms, arthropods and rodents-were considered, as the organisers believe that it is necessary to address the total pest management problems in each particular growing area, and the variety of the papers indicates the importance of a multi disciplinary approach to their solution. Rice is one of the most important world crops and is the major source of food for around 60% of the world's population, with a world production of 500 million tonnes from 150 million hectares of land. Since world stocks amount to only two months supply, many people are at risk from famine. Moreover, it has been esti mated that the world requirement in 2020 will be about 760 million tonnes, an increase of 50%. This pressure of population on food makes efficient pest management vital and is the reason for bringing together experts from all over the world to this major conference.
