Download or read book Pulse crops for sustainable farms in sub Saharan Africa written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-05-22 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pulses have a long history in sub-Saharan Africa due to their multiple benefits. Pulses, and legumes in general, can play an important role in agriculture because of their ability to biologically fix atmospheric nitrogen and to enhance the biological turnover of phosphorus; thus they could become the cornerstone of sustainable agriculture in Africa. In this sense, there is a body of literature that points to diversification of existing production systems – particularly legumes species, which provide critical environmental services, including soil erosion control and soil nutrient recapitalization. This publication is a review of some of the promising strategies to support the cultivation and utilization of pulses on smallholder farms in sub-Saharan Africa. The review is part of the legacy of the International Year of Pulses (IYP), which sought to recognize the contribution that pulses make to human well-being and the environment.

Download or read book Legumes for Soil Health and Sustainable Management written by Ram Swaroop Meena and published by Springer. This book was released on 2018-07-06 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable management of soils is an important global issue of the 21st century. Feeding roughly 8 billion people with an environmentally sustainable production system is a major challenge, especially considering the fact that 10% of the world’s population at risk of hunger and 25% at risk of malnutrition. Accordingly, the 68th United Nations (UN) general assembly declared 2016 the “International Year of Pulses” to raise awareness and to celebrate the role of pulses in human nutrition and welfare. Likewise, the assembly declared the year 2015 as the “International Year of Soils” to promote awareness of the role of “healthy soils for a healthy life” and the International Union of Soil Science (IUSS) has declared 2015-2024 as the International Decade of Soils. Including legumes in cropping systems is an important toward advancing soil sustainability, food and nutritional security without compromising soil quality or its production potential. Several textbooks and edited volumes are currently available on general soil fertility or on legumes but‚ to date‚ none have been dedicated to the study of “Legumes for Soil Health and Sustainable Management”. This is important aspect, as the soil, the epidermis of the Earth (geoderma)‚ is the major component of the terrestrial biosphere. This book explores the impacts of legumes on soil health and sustainability, structure and functioning of agro-ecosystems, agronomic productivity and food security, BNF, microbial transformation of soil N and P, plant-growth-promoting rhizobacteria, biofertilizers, etc. With the advent of fertilizers, legumes have been sidelined since World War II, which has produced serious consequences for soils and the environment alike. Therefore, legume-based rational cropping/soil management practices must support environmentally and economically sustainable agroecosystems based on (sequential) rotation and intercropping considerations to restore soil health and sustainability. All chapters are amply illustrated with appropriately placed data, tables, figures, and photographs, and supported with extensive and cutting-edge references. The editors have provided a roadmap for the sustainable development of legumes for food and nutritional security and soil sustainability in agricultural systems, offering a unique resource for teachers, researchers, and policymakers, as well as undergraduate and graduate students of soil science, agronomy, ecology, and the environmental sciences.

Download or read book Broadening the Genetic Base of Crop Production written by H. David Cooper and published by . This book was released on 2001 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the previously neglected interface between the conservation of plant genetic resources and their utilization. Only through utilization can the potential value of conserved genetic resources be realized. However, as this book shows, much conserved germplasm has to be subjected to long-term pre-breeding and genetic enhancement before it can be used in plant breeding programs.The authors explore the rationale and approaches for such pre-breeding efforts as the basis for broadening the genetic bases of crop production. Examples from a range of major food crops are presented and issues analyzed by leading authorities from around the world.
Download or read book Recent Advances in the Diagnosis and Management of Plant Diseases written by L.P. Awasthi and published by Springer. This book was released on 2015-11-19 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of the most challenging and significant chapters on the diagnosis and management of important bacterial, fungal, viral, viroid, phytoplasma, non parasitic diseases and various physiological disorders, in various crops. The chapters have been contributed by eminent plant pathologists, having wide experience of teaching and research on various crops with different types of diseases, which cause great economic losses. The book would be very useful for students, teachers and researchers of plant pathology. This book highlights recent advances made in the development of new types of resistance in host plants and alternative strategies for managing plant diseases to improve food quality and reduce the negative public health impact associated with plant diseases. Having entered into 21st century advancements in the Diagnosis of Plant Pathogens and Plant Disease Management need to be closely examined and adequately applied, so that newer challenges facing plant pathology could be adequately addressed in attaining food security for the growing population. Substantial advancements have been made in terms of expanding knowledge base of the biology of plant-microbial interactions, disease management strategies and application and practice of Plant Pathology. Application of molecular biology in Plant Pathology has greatly improved our ability to detect plant pathogens and in increasing our understanding, their ecology and epidemiology. Similarly, new technologies and resources have been evolved for the development of sustainable crop protection systems by different control strategies against various pests and pathogens that are important components of the integrated pest management programme. Natural products and chemical compounds discovered as a result of basic research and molecular mechanisms of pathogenesis have led to the development of “biorational” pesticides. Biological control has been found to be the most significant approach to plant health management during the twentieth century and promises using modern biotechnology, to be even more significant in the twenty-first century.
Download or read book Guide for Field Crops in the Tropics and the Subtropics written by Agency for International Development and published by . This book was released on 2005-01-01 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the tropical and subtropical areas of the world, food grains make up the bulk of the diet for most people. Food grains together with fiber and specialty crops are also principal cash producers. It is with these commodities that this Guide for Field Crops in the Tropics and Subtropics concerns itself. The Guide deals with general situations; local applications are beyond the range of this moderate-size volume, but the basic information presented will permit area-by-area adaptations. This concise, up-to-date Guide is composed of 40 chapters. The first four are general introductory chapters, and treat rather extensively the important subjects of climate, soil, cropping, and farming systems as related to the tropics and subtropics. The other 36 chapters are divided as follows: 6 on cereal crops, 9 on food legumes, 6 on oil crops, 7 on root or tuber crops and bananas, 6 on major fiber crops and 2 on other cash crops. These chapters do not attempt to deal with the factors of providing inputs such as national supplies of fertilizer, insecticides and fungicides.

Download or read book Environmental Stress in Plants written by Joe H. Cherry and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental stresses represent the most limiting factors to agricultural productivity worldwide. Their impact is not only on presently cultivated crops, they are also significant barriers to the introduction of crop plants in noncultivated areas. A significant global problem in the improvement of agriculture is the major variation in annual crop yields due to variations in environmental stresses such as drought, flooding, salinity, and temperature variations. This summary presents current background and research knowledge on all important environmental stresses and their respective influence on plant growth, development and crop yield as well as on biochemical and physiological events within plant tissues in reaction to changing environmental conditions.
Download or read book Altered Ecologies written by Simon Haberle and published by ANU E Press. This book was released on 2010-11-01 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: Like a star chart this volume orientates the reader to the key issues and debates in Pacific and Australasian biogeography, palaeoecology and human ecology. A feature of this collection is the diversity of approaches ranging from interpretation of the biogeographic significance of plant and animal distributional patterns, pollen analysis from peats and lake sediments to discern Quaternary climate change, explanation of the patterns of faunal extinction events, the interplay of fire on landscape evolution, and models of the environmental consequences of human settlement patterns. The diversity of approaches, geographic scope and academic rigor are a fitting tribute to the enormous contributions of Geoff Hope. As made apparent in this volume, Hope pioneered multidisciplinary understanding of the history and impacts of human cultures in the Australia- Pacific region, arguably the globe's premier model systems for understanding the consequences of humans colonization on ecological systems. The distinguished scholars who have contributed to this volume also demonstrate Hope's enduring contribution as an inspirational research leader, collaborator and mentor. Terra Australis leave no doubt that history matters, not only for land management, but more importantly, in alerting settler and indigenous societies alike to their past ecological impacts and future environmental trajectories.
