Download or read book Integrating New Technologies for Striga Control written by Gebisa Ejeta and published by World Scientific. This book was released on 2007 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Witchweeds (Striga species) decimate agriculture in much of Africa and parts of Asia, attacking the major cereal grains and legumes, and halving the already very low yields of subsistence farmers. Several years of research have provided promising technologies, based on the fundamental biology of the parasite?host associations, for dealing with this scourge. However, there is an apparent realization that these technologies will fail because highly successful weeds such as Striga evolve resistance to all types of controls unless proven methods are integrated with each other for a more sustainable solution.Integration is often an anathema to basic scientists who typically deal with single variables and solutions. However, key leaders in the development of the new knowledge-based control strategies, already in the field and under development, recently joined forces to develop strategies and projects in order to integrate the technologies in a symposium in Ethiopia in November 2006. The encouraging results are described in this peer-reviewed book, authored by leaders in the field who have been supplying the basic biology, genetics, biochemistry, and molecular information that have offered insights and generated technologies in how to deal with Striga.

Download or read book Lost Crops of Africa written by National Research Council and published by National Academies Press. This book was released on 1996-02-14 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scenes of starvation have drawn the world's attention to Africa's agricultural and environmental crisis. Some observers question whether this continent can ever hope to feed its growing population. Yet there is an overlooked food resource in sub-Saharan Africa that has vast potential: native food plants. When experts were asked to nominate African food plants for inclusion in a new book, a list of 30 species grew quickly to hundreds. All in all, Africa has more than 2,000 native grains and fruitsâ€""lost" species due for rediscovery and exploitation. This volume focuses on native cereals, including: African rice, reserved until recently as a luxury food for religious rituals. Finger millet, neglected internationally although it is a staple for millions. Fonio (acha), probably the oldest African cereal and sometimes called "hungry rice." Pearl millet, a widely used grain that still holds great untapped potential. Sorghum, with prospects for making the twenty-first century the "century of sorghum." Tef, in many ways ideal but only now enjoying budding commercial production. Other cultivated and wild grains. This readable and engaging book dispels myths, often based on Western bias, about the nutritional value, flavor, and yield of these African grains. Designed as a tool for economic development, the volume is organized with increasing levels of detail to meet the needs of both lay and professional readers. The authors present the available information on where and how each grain is grown, harvested, and processed, and they list its benefits and limitations as a food source. The authors describe "next steps" for increasing the use of each grain, outline research needs, and address issues in building commercial production. Sidebars cover such interesting points as the potential use of gene mapping and other "high-tech" agricultural techniques on these grains. This fact-filled volume will be of great interest to agricultural experts, entrepreneurs, researchers, and individuals concerned about restoring food production, environmental health, and economic opportunity in sub-Saharan Africa.

Download or read book Strigolactones Biology and Applications written by Hinanit Koltai and published by Springer. This book was released on 2019-04-02 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the exciting biology and chemistry of strigolactones. Outgrowth of shoot branches? Development of lateral roots? Interactions with beneficial microorganisms? Avoiding parasitic plants? Responding to drought conditions? These important “decisions” that plants make are all regulated by a group of hormones called strigolactones. The latest research has yielded a number of new biological concepts, such as a redefinition of plant hormones and their crosstalk, new functional diversity of receptors, hormonal “smoke and mirrors,” core signaling pathways, and even phloem transport of receptor proteins. Another important aspect of strigolactones is the related synthetic chemistry, which could pave the way for a variety of potential applications in agriculture and medicine. The book explains in detail the role that strigolactones play in plant development, and addresses the interaction of plants with soil biota and abiotic stress conditions, prospects of strigolactone biochemistry and evolution, and chemical synthesis of natural strigolactones and analogs, together with their potential applications. Including a glossary and end-of-chapter synopses to aid in comprehension, it offers a valuable asset for teachers, lecturers and (post-) graduate students in biology, agronomy and related areas..
Download or read book Food Crop Production by Smallholder Farmers in Southern Africa written by Ambayeba Muimba-Kankolongo and published by Academic Press. This book was released on 2018-02-07 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food Crop Production by Smallholder Farmers in Southern Africa: Challenges and Opportunities for Improvement evaluates traditional cultivation practices used by smallholder farmers, providing a synthesis of the latest information on increasing crop yield through adoption of research innovations. The book catalogs smallholder cultivation practices and recommends innovative strategies for improving the agriculture sector including: management practices that reduce net carbon emissions; technologies that improve soil structures and conserve the natural resources base; means of empowering female resources along value chains; and government commitment to adopt policies that enhance agriculture productivity by encouraging farmers to use environmentally sound cultivation technologies. Traditional farming techniques often produce negative impacts on the environment and ecosystem resulting in outbreaks of diseases and pests. In addition to the region's recurrent droughts, these outbreaks of numerous diseases and pests, weeds and other invasive plants put thousands at risk of poverty and hunger, as well as malnutrition. This book presents enhanced agricultural production technologies for ensuring adequate food production, safety and nutritional quality for the population of Southern Africa and forms the basis for an increased SADC regional effort in food production through which financial and trade institutions can improve stakeholder capacities, encourage micro-enterprise development and enhance employment and regional trade. - Provides a critical synthesis of data and information for increasing crop yield through adoption of research innovations - Evaluates traditional and scientific interventions that address food security issues of the poor farmers in the region - Presents agro-ecologies of countries in the region and how they relate to various cultivation practices - Catalogs smallholder cultivation practices and recommends innovative strategies for improving the agriculture sector
Download or read book Biotic Stress Resistance in Millets written by I. K. Das and published by Academic Press. This book was released on 2016-08-03 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biotic Stress Resistance in Millets presents an important guide to the disease and pest-related challenges of this vital food crop. Biotic stresses are one of the major constraints for millet production, but newly emerging and forward-thinking problems with disease and insect pests are likely to increase as a result of changing weather, making this an imperative book on best practices. Current strategies are mainly through the development of resistant cultivars, as the use of chemicals is cost-prohibitive to many of those producing millet in developing countries where it is of most value as a food source. This book explores non-chemical focused options for improving plant resistance and protecting crop yield. This single-volume reference will be important for researchers, teachers and students in the disciplines of Agricultural Entomology, Plant protection, Resistance Plant Breeding and Biotechnological pest management. - Establishes basic concepts of host resistance providing foundational insight - Synthesizes past biotic stress resistance research with the latest findings to orient research for future strategies for plant protection - Focuses exclusively on host plant resistance on all major diseases and pests of millets - Presents data and strategies that are globally applicable as millets gain importance as a health food

Download or read book Cereal Genomics written by P. K. Gupta and published by Springer Science & Business Media. This book was released on 2004-12-20 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first of its kind, where twenty chapters written by experts of international repute, cover all aspects of cereal genomics research. In recent years genomics has become a thrust area of research in life sciences, and cereals, being the most important group of crops, their genomes have been subjected to intensive/extensive analyses. The knowledge and the products generated through cereal genomics research are already being used for plant breeding through both, the marker assisted selection (MAS) and transgenic cereals. The areas covered in this book include, development and use of all kinds of molecular markers (including SNPs), construction and use of molecular maps, study of population genetics and domestication of cereals using tools of genomics research, structural and functional genomics (including whole genome sequencing in Arabidopsis and rice), comparative genomics, QTLs (including epistatic and e-QTLs) and genes for resistance against biotic and abiotic stresses, marker assisted selection (MAS), map-based cloning of genes/QTLs and the use of genomics research for crop improvement. The book, therefore, should prove useful not only for students and teachers, but also for the young research workers, who are starting their research career in the field of cereal genomics.
Download or read book Parasitic flowering plants written by Henning Heide-Jørgensen and published by BRILL. This book was released on 2008-07-31 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitic flowering plants are strikingly impressive and beautiful and hold many surprises of both general and scientific interest. Parasites also have great influence on the quality of human life when attacking crop plants. Some parasites have since early times appealed to our imagination and have been part of religious or folkloristic events and used as gifts to royalties. This beautifully illustrated book covers all parasitic families and most of the genera. It also discusses the establishment of the parasite, the structure and function of the nutrient absorption organ (haustorium), and how the parasites are pollinated and dispersed as well as their ecology, hosts, and evolution. The book is written in a mostly non-technical language and is provided with a glossary and explanatory boxes. For additional information about this book, including some sample photographs, as well as a list of corrections that have been incorporated in the 2011 reprint, please visit the author's web site. Parasitic Flowering Plants was nominated by The Council on Botanical and Horticultural Libraries for the 2010 Annual Award for a Significant Work in Botanical or Horticular Literature, in the category ‘Technical Interest’.
