Download or read book East African Weeds and Their Control written by G. W. Ivens and published by . This book was released on 1989 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Man's agricultural activities are largely concerned with prevention of weeds taking over from his crops and in the last few decades, methods of controlling weeds have become increasingly sophisticated with the development of Weeds Science as a field of study in its own right. Identification of the plant concerned is essential. The aim of this book is to aid identification of most of the common East African weeds by providing line drawings and descriptions of them using the minimum of technical terms, and to show distribution, agricultural importance, and possibilities for their chemical control. This book has been written primarily for students, advisors and research workers in agriculture. It will also be of value to farmers, gardeners, environmentalists and all those concerned with the plants found on land used for cropping or livestock production.

Download or read book Biology and Management of Problematic Crop Weed Species written by Bhagirath Chauhan and published by Elsevier. This book was released on 2021-09-04 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weeds are the main biological constraint to crop production throughout the year. Uncontrolled weeds could cause 100% yield loss. In Australia, the overall cost of weeds to Australian grain growers was estimated at AU$ 3.3 billion annually. In terms of yield losses, weeds amounted to 2.7 million tonnes of grains at a national level. In the USA, weeds cost US$ 33 billion in lost crop production annually. In India, these costs were estimated to be much higher (US$ 11 billion). These studies from different economies suggest that weeds cause substantial yield and economic loss. Biology and Management of Problematic Weed Species details the biology of key weed species, providing vital information on seed germination and production, as well as factors affecting weed growth. These species include Chenopodium album, Chloris truncata and C. virgate, Conyza bonariensis and C. canadensis, Cyperus rotundus, and many more. This information is crucial for researchers and growers to develop integrated weed management (IWM) strategies. Written by leading experts across the globe, this book is an essential read to plant biologists and ecologists, crop scientists, and students and researchers interested in weed science. - Provides detailed information on the biology of different key weed species - Covers weed seed germination and emergence - Presents the factors affecting weed growth and seed production
Download or read book General Agriculture for West Africa written by Q.B. Olatunji Anthonio and published by Routledge. This book was released on 2019-08-06 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1979. This study examines various aspects of agriculture in West Africa. There is a strong chapter on the economics of agriculture and records, farm machinery, agricultural improvement, fish and the basics of crop and livestock production are all dealt with. The role of government policy in the improvement of agriculture is also examined. This title will be useful to undergraduates concerned with agriculture who want a good grounding before going on to their specialised fields of the applied sciences, as well as to those interested in commercial farming and policy makers in civil administration.

Download or read book Identification and Control of Common Weeds written by Zhenghao Xu and published by Springer. This book was released on 2017-11-09 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces readers to nearly 600 common weeds. In addition to essential information, each chapter includes photos for a specific type of weed to show its morphology in different growth periods, such as seedling, root, flower, fruit, and mature plant. The book also discusses control measures, including agricultural, chemical, physical, biological, and comprehensive methods. The Volume1 mainly focuses on 126 species of grass weeds and 34 species of sedge weeds. With the development of society and economics, weeds have become a recurring problem. In particular, the exotic, invasive, and quarantine weeds have spread dramatically and rapidly. On the other hand, many people, even those who are engaged in weed control, do not (or cannot) distinguish between weeds. Thus there is significant demand for illustrations of weed morphologies, as well as information on their control measures. This book offers a valuable, practical guide for all those working in the fields of crop cultivation, plant protection and quarantine management.

Download or read book Lost Crops of Africa written by National Research Council and published by National Academies Press. This book was released on 2006-10-27 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is the second in a series of three evaluating underexploited African plant resources that could help broaden and secure Africa's food supply. The volume describes the characteristics of 18 little-known indigenous African vegetables (including tubers and legumes) that have potential as food- and cash-crops but are typically overlooked by scientists and policymakers and in the world at large. The book assesses the potential of each vegetable to help overcome malnutrition, boost food security, foster rural development, and create sustainable landcare in Africa. Each species is described in a separate chapter, based on information gathered from and verified by a pool of experts throughout the world. Volume I describes African grains and Volume III African fruits.
