Download or read book Parthenium Weed written by Stephen W Adkins and published by CABI. This book was released on 2018-11-07 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the most important aspects of the biology, ecology and management of what is one of the world's worst weeds. Originally regarded as a major weed in Australia and India, Parthenium weed is now widespread in around 48 countries in Africa, Asia and the South Pacific, and has the potential to spread to new countries in Africa, Asia and Europe. This book, which is a collective effort by 27 members of the International Parthenium Weed Network, addresses research and knowledge gaps for different countries. It examines the weed's mode of spread, its impact on agricultural production, its effect on the environment and on human health, and its management using biological control, as well as cultural, physical and chemical approaches. It also considers the coordination of the weed's management, possible uses for Parthenium weed, its present distribution and how this is impacted by climate change. This book includes: A detailed analysis of Parthenium weed biology. Experiences with Parthenium weed worldwide. An explanation of practical management options. This book will be of interest to graduate students and researchers in universities and institutes, in the fields of plant ecology, botany, agriculture, conservation and restoration ecology.

Download or read book Biosalinity in Action Bioproduction with Saline Water written by D. Pasternak and published by Springer Science & Business Media. This book was released on 1985-11-30 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, scientists and laymen have regarded salinity as a hazar dous, detrimental phenomenon. This negative view was a principal reason for the lack of agricultural development of most arid and semi arid zones of the world where the major sources of water for biological production are saline. The late Hugo Boyko was probably the first scientist in recent times to challenge this commonly held, pessimistic view of salinity. His research in Israel indicated that many plants can be irrigated with saline water, even at seawater strength, if they are in sandy soil - a technique that could open much barren land to agriculture. This new, even radical, approach to salinity was clearly enunciated in the book he edited and most appropriately entitled 'Salinity and Aridity: New Approaches to Old Problems' (1966). A decade later, three members of the United States National Science Foundation (NSF), Lewis Mayfield, James Aller and Oskar Zaborsky, formulated the 'Biosaline Concept'; namely, that poor soils, high solar insolation and saline water, which prevail in arid lands, should be viewed as useful resources rather than as disadvantages, and that these resources can be used for non-traditional production of food, fuels and chemicals. The First International Workshop on Biosaline Research was con vened at Kiawah Island, South Carolina, in 1977 by A. San Pietro.

Download or read book Nutrient Requirements of Beef Cattle written by Subcommittee on Beef Cattle Nutrition and published by National Academies Press. This book was released on 2000-05-16 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.
Download or read book East Africa s grasses and fodders Their ecology and husbandry written by G. Boonman and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series Tasks for Vegetation Science is devoted to a variety of research aspects in vegetation science, pure as wellas applied. Of the applied problems one of the most pressing is to achieve better knowledge and improvement of the pasture vegetation in tropical and subtropical regions. As series editor I was impressed by the sheer volume of useful scientific information concerning pasture plants from East Africa collected during many years by Dr. Boonman and compiled in one manuscript. Dr. Boonman first came to East Africa in 1963 on an overland journey along the river Nile which took him from Alexandria in Egypt to Lake Victoria in Uganda and Kenya and back again. After a brief spell as a cotton agronomist in the Sudan Gezira he joined the grassland research team at Kitale, Kenya in 1966. Improvement ofseed yield oftropical grasses was his principal interest which finally led him into the fieldof breeding grasses. Well-known varieties from his work include Boma & Elmba Rhodesgrass as wellas Clone 13Elephantgrass. In 1979he was recalled to The Netherlands to head a cooperative seedcompany involved in the breeding of grasses and cereals. The author has focused this study on one region, Eastern Africa.Global application of theories runs into conflicts too easily with local types of farming, if not with bare economics. Very few books can be found that describe existing practices and seek local answers by digging deep in the stacks of old, local reports.
Download or read book Saline and Alkaline Soils in Latin America written by Edith Taleisnik and published by Springer Nature. This book was released on 2020-09-26 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first comprehensive overview of saline and alkaline soils in Latin America, known for having one of the most extensive surface of salt-affected soils in the world. It is organized along two main axes: soils and vegetation. The book discusses the occurrence of such soils in the region, focusing mainly in management strategies for their sustainable use, and it presents accounts of natural vegetation and crops in the various environments of the region. Social impacts of such conditions and ongoing projects to overcome them are considered. Likewise, the book highlights physiological mechanisms that are responsible for the negative effects these soils exert on crops and forest resources and determine vegetation distribution in them. Plant breeding challenges and new perspectives for such environments are discussed. Technologies such as irrigation and drainage are included. The readership includes soil and plant scientists, as well as policy makers.

It is not the intention to undertake to guide or to direct the choice of a particular farm, but to supply the settler with initial information concerning the region in which he would like to establish a farm home."--Page ii.
Download or read book Quality Declared Seed System written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2006 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The quality declared seed system, as set out in the FAO Plant Production and Production Paper No. 117 (1993, ISBN 9251032785) has been widely used, particularly by those working in the field of emergency seed supply and as a source of practical information on seed standards for a range of crop species. The system provided an alternative for seed quality assurance, which was less demanding than full seed quality control systems. This publication sets out a revised version, prepared by an expert consultation, which offers a more explicit recognition of the role of national policies and the impact of some recent international obligations on seed provision and a clearer explanation on how quality declared seeds can accommodate local varieties. The list of crops now includes 92 species, of which 21 include open pollinated and hybrids and one includes also a synthetic variety. In making this update, FAO sought to improve seed supplies to farmers and thus to contribute to food security.
