Book Synopsis Yield Gains in Major U.S. Field Crops by : Stephen Smith
Download or read book Yield Gains in Major U.S. Field Crops written by Stephen Smith and published by John Wiley & Sons. This book was released on 2020-01-22 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: When humankind began to save seed to plant for the next season, they did so hoping to secure a food supply for the future. With that came the inevitable question: Will it be enough? Scientists today are still asking that question. Our dependence on domesticated cultivated varieties has never been greater, even as increasing populations strain our resource base. This book provides a fascinating snapshot-in-time account of the productivity status of all major U.S. field crops. Each crop has a different story to tell. Plant breeding, biotechnology, and agronomy have shaped these stories. It is imperative that we learn from them to ensure continued productivity. The solution is long-term stewardship and the most effective use of our critical resources—water, soil, genetic resources, and human intellect.

Available in PDF, EPUB and Kindle. Book excerpt: Outlining successful breeding techniques to augment the yields of the world's major crops, this reference analyzes the physiological and genetic basis for past and potential future increases in crop yields.;Covering crops with wide differences in morphology, photosynthetic rates, and nitrogen metabolisms, Genetic Improvement of Field Crops: investigates the changes produced by breeders in the physiological attributes affecting wheat grain yield and nitrogen content during the last century; discusses those crop characteristics of oats that have already been altered or might be manipulated through breeding to further increase yield potential; describes several genetic factors responsible for both yield potential and stress resistance in barley; offers insights into the relationship between increases in the yield potential and stress tolerance of corn; examines the evolution of sunflower crop yields and yield stability and estimates the contribution of improved cultivars; evaluates the effects of breeding on tuber characteristics related to the crop growth and yield of the potato; elucidates the possibilities for simultaneous improvement of yield and fiber strength in cotton; and identifies the features to be considered in the development of high yielding varieties of rice for different agricultural systems.;Providing nearly 1600 key literature citations allowing further in-depth study of particular topics, Genetic Improvement of Field Crops is for plant physiologists and breeders, crop and agricultural scientists, agronomists, biochemists, geneticists, biotechnologists, microbiologists, and upper-level undergraduate and graduate students in these disciplines.

Book Synopsis Yield gap analysis of field crops by : Food and Agriculture Organization of the United Nations
Download or read book Yield gap analysis of field crops written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-06-29 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: To feed a world population that will exceed 9 billion by 2050 requires an estimated 60% increase over current primary agricultural productivity. Closing the common and often large gap between actual and attainable crop yield is critical to achieve this goal. To close yield gaps in both small and large scale cropping systems worldwide we need (1) definitions and techniques to measure and model yield at different levels (actual, attainable, potential) and different scales in space (field, farm, region, global) and time (short and long term); (2) identification of the causes of gaps between yield levels; (3) management options to reduce the gaps where feasible and (4) policies to favour adoption of sustainable gap-closing solutions. The aim of this publication is to critically review the methods for yield gap analysis, hence addressing primarily the first of these four requirements, reporting a wide-ranging and well-referenced analysis of literature on current methods to assess productivity of crops and cropping systems.
Book Synopsis Seed Biology and Yield of Grain Crops, 2nd Edition by : Dennis B Egli
Download or read book Seed Biology and Yield of Grain Crops, 2nd Edition written by Dennis B Egli and published by CABI. This book was released on 2017-02-23 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new edition of an established title examines the determination of grain crop yield from a unique perspective, by concentrating on the influence of the seed itself. As the food supply for an expanding world population is based on grain crops harvested for their seeds, understanding the process of seed growth and its regulation is crucial to our efforts to increase production and meet the needs of that population. Yield of grain crops is determined by their assimilatory processes such as photosynthesis and the biosynthetic processes in the seed, which are partly regulated within the seed itself. Substantially updated with new research and further developments of the practical applications of the concepts explored, this book is essential reading for those concerned with seed science and crop yield, including agronomists, crop physiologists, plant breeders, and extension workers. It is also a valuable source of information for lecturers and graduate students of agronomy and plant physiology.

Book Synopsis Population, Agriculture, and Biodiversity by : J. Perry Gustafson
Download or read book Population, Agriculture, and Biodiversity written by J. Perry Gustafson and published by University of Missouri Press. This book was released on 2020-05-04 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely collection of 15 original essays written by expert scientists the world over addresses the relationships between human population growth, the need to increase food supplies to feed the world population, and the chances for avoiding the extinction of a major proportion of the world's plant and animal species that collectively makes our survival on Earth possible. These relationships are highly intertwined, and changes in each of them steadily decrease humankind’s chances to achieve environmental stability on our fragile planet. The world population is projected to be nine to ten billion by 2050, signaling the need to increase world food production by more than 70 percent on the same amount of land currently under production—and this without further damaging our fragile environment. The essays in this collection, written by experts for laypersons, present the problems we face with clarity and assess our prospects for solving them, calling for action but holding out viable solutions.

Book Synopsis Genetically Engineered Crops by : National Academies of Sciences, Engineering, and Medicine
Download or read book Genetically Engineered Crops written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-01-28 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.
