Available in PDF, EPUB and Kindle. Book excerpt: The prime objective of plant breeding is to increase productivity to meet the increasing food requirements of people. Estimation of genetic progress from a breeding program and periodic evaluation of advancement in the genetic gain of a crop through released varieties is required to understand changes and success produced by past breeding activities. Since its inception Ethiopian Agricultural Research, Crop Research Sector in which field pea was included as one component of food legume improvement program has been working much on development of new technologies contributing to sustainable development. As a result, more than 30 field pea (Pisum sativum L.) improved varieties have been developed in Ethiopia, from 1979 to 2010. This work presents the impact of breeding field pea on seed yield, associated traits and their related changes in Ethiopia due to past pea breeding activities. The work also provides information on the potential for improvement of the crop and points out future directions for improvement of the crop.

Download or read book Grain Legumes written by Antonio M. De Ron and published by Springer. This book was released on 2015-08-27 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to grain legumes and include eight chapters devoted to the breeding of specific grain legume crops and five general chapters dealing with important topics which are common to most of the species in focus. Soybean is not included in the book as it is commonly considered an oil crop more than a grain legume and is included in the Oil Crops Volume of the Handbook of Plant Breeding.Legume species belong to the Fabaceae family and are characterized by their fruit, usually called pod. Several species of this family were domesticated by humans, such as soybean, common bean, faba bean, pea, chickpea, lentil, peanut, or cowpea. Some of these species are of great relevance as human and animal food. Food legumes are consumed either by their immature pod or their dry seeds, which have a high protein content. Globally, grain legumes are the most relevant source of plant protein, especially in many countries of Africa and Latin America, but there are some constraints in their production, such as a poor adaptation, pest and diseases and unstable yield. Current research trends in Legumes are focused on new methodologies involving genetic and omic studies, as well as new approaches to the genetic improvement of these species, including the relationships with their symbiotic rhizobia.

Download or read book Plant Genetic Resources of Ethiopia written by Jan Engels and published by Cambridge University Press. This book was released on 1991-03-21 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the world centers of crop evolution and origin, Ethiopia has long been recognized as an important area of diversity for several major and various minor crops. Based on an international conference held in Addis Ababa, this book describes how plant genetic diversity in Ethiopia is of vital importance in breeding new varieties of crops with desirable characteristics, such as increased resistance to pests and diseases and greater adaptation to heat and drought. The three main sections in the book consider the Ethiopian center of diversity, germ plasm or genetic material collection and conservation in Ethiopia, and the evaluation and utilization of Ethiopian genetic resources. A broad range of food and feed crops and plants of medicinal and industrial importance are discussed, both at a national and international level. A brief account of conservation strategies and gene bank problems unique to Ethiopia is also given. The importance of Ethiopia's plant genetic resources to world agriculture has been demonstrated on more than one occasion. Plant breeders, geneticists, and botanists throughout the world will, therefore, find this unique book a valuable source of information and an essential reference work.

Download or read book Legumes in Cropping Systems written by Donal Murphy-Bokern and published by Cabi. This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on contributions from members of the Legumes Future research consortium and complemented by articles from other research teams, this book provides a comprehensive overview of knowledge relevant to developing legume-supported cropping systems in Europe. It reflects the growing interest in using legumes to improve cropping and the current debate over the imbalance in European systems where the low use of legumes has caused concern in the agricultural policy community. This book supports informed debate and decision-making that addresses the associated challenges. Legumes in Cropping Systems presents current knowledge on this subject across 15 coordinated chapters. Each chapter addresses a specific aspect of legume cropping and provides insight into the relevant literature to help support understanding and explore the underlying processes that influence cropping system development. This book includes coverage of: · the role of legumes in cropping systems; · the role of legumes in European protein supplies; · environmental effects of grain and forage legumes; · current status of the major grain and forage legume crops; · economic effects; and · policy development. Written by an international team of expert authors and presented in full-colour throughout, this book is an invaluable resource for researchers in agronomy and crop sciences, agricultural professionals, policy makers, and students.
Download or read book Soil Organic Matter in Sustainable Agriculture written by Fred Magdoff and published by CRC Press. This book was released on 2004-05-27 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recognition of the importance of soil organic matter (SOM) in soil health and quality is a major part of fostering a holistic, preventive approach to agricultural management. Students in agronomy, horticulture, and soil science need a textbook that emphasizes strategies for using SOM management in the prevention of chemical, biological, and physical problems. Soil Organic Matter in Sustainable Agriculture gathers key scientific reviews concerning issues that are critical for successful SOM management. This textbook contains evaluations of the types of organic soil constituents—organisms, fresh residues, and well-decomposed substances. It explores the beneficial effects of organic matter on soil and the various practices that enhance SOM. Chapters include an examination of the results of crop management practices on soil organisms, organic matter gains and losses, the significance of various SOM fractions, and the contributions of fungi and earthworms to soil quality and crop growth. Emphasizing the prevention of imbalances that lead to soil and crop problems, the text also explores the development of soils suppressive to plant diseases and pests, and relates SOM management to the supply of nutrients to crops. This book provides the essential scientific background and poses the challenging questions that students need to better understand SOM and develop improved soil and crop management systems.
