This book was released on 2001-12-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen in the Environment: Sources, Problems, and Management is the first volume to provide a holistic perspective and comprehensive treatment of nitrogen from field, to ecosystem, to treatment of urban and rural drinking water supplies, while also including a historical overview, human health impacts and policy considerations. It provides a worldwide perspective on nitrogen and agriculture. Nitrogen is one of the most critical elements required in agricultural systems for the production of crops for feed, food and fiber. The ever-increasing world population requires increasing use of nitrogen in agriculture to supply human needs for dietary protein. Worldwide demand for nitrogen will increase as a direct response to increasing population. Strategies and perspectives are considered to improve nitrogen-use efficiency. Issues of nitrogen in crop and human nutrition, and transport and transformations along the continuum from farm field to ground water, watersheds, streams, rivers, and coastal marine environments are discussed. Described are aerial transport of nitrogen from livestock and agricultural systems and the potential for deposition and impacts. The current status of nitrogen in the environment in selected terrestrial and coastal environments and crop and forest ecosystems and development of emerging technologies to minimize nitrogen impacts on the environment are addressed. The nitrogen cycle provides a framework for assessing broad scale or even global strategies to improve nitrogen use efficiency. Growing human populations are the driving force that requires increased nitrogen inputs. These increasing inputs into the food-production system directly result in increased livestock and human-excretory nitrogen contribution into the environment. The scope of this book is diverse, covering a range of topics and issues from furthering our understanding of nitrogen in the environment to policy considerations at both farm and national scales.

Download or read book Corn and Grain Sorghum Comparison written by Yared Assefa and published by Academic Press. This book was released on 2013-12-16 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corn and grain sorghum (Sorghum bicolor subsp. bicolor L) are among the top cereal crops world wide, and both are key for global food security. Similarities between the two crops, particularly their adaptation for warm-season grain production, pose an opportunity for comparisons to inform appropriate cropping decisions. This book provides a comprehensive review of the similarities and differences between corn and grain sorghum. It compares corn and sorghum crops in areas such as morphology, physiology, phenology, yield, resource use and efficiency, and impact of both crops in different cropping systems. Producers, researchers and extension agents in search of reliable scientific information will find this in-depth comparison of crops with potential fit in dryland and irrigations cropping systems particularly valuable. - Presents a wide range of points of comparison - Offers important insights for crop decision making
Download or read book Deficit Irrigation Practices written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2002 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of improving water productivity, there is a growing interest in deficit irrigation, an irrigation practice whereby water supply is reduced below maximum levels and mild stress is allowed with minimal effects on yield. Under conditions of scarce water supply and drought, deficit irrigation can lead to greater economic gains than maximizing yields per unit of water for a given crop; farmers are more inclined to use water more efficiently, and more water-efficient cash crop selection helps optimize returns. However, this approach requires precise knowledge of crop response to water as drought tolerance varies considerably by species, cultivar and stage of growth. The studies present the latest research concepts and involve various practices for deficit irrigation. Both annual and perennial crops were exposed to different levels of water stress, either during a particular growth phase, throughout the whole growing season or in a combination of growth stages. The overall finding, based on the synthesis of the different contributions, is that deficit or regulated-deficit irrigation can be beneficial where appropriately applied. Substantial savings of water can be achieved with little impact on the quality and quantity of the harvested yield. However, to be successful, an intimate knowledge of crop behavior is required, as crop response to water stress varies considerably.

Download or read book Maize Stress Ecophysiology and Regulation written by Jiwang Zhang and published by Frontiers Media SA. This book was released on 2023-11-27 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: To face the double pressures from the changing environment and increasing demand of the growing population globally, maize plays an essential role in securing food safety due to its strong adaptability. With climate change, the severity of extreme environmental stresses is projected to be more frequent, which affects maize growth, physiological processes, and productivity. It is important to explore the physiological mechanisms and regulatory measures in response to abiotic stresses. The interactions between crop and environmental stresses are multistep and complex. The stress resistance response of maize is still an extremely complicated process. Studies on responses of maize growth, yield, or quality under stress conditions are growing exponentially, but the description at a physiological or biochemical level is still unclear. In addition, new knowledge of maize hybrids with adversity resistance has not been deeply excavated. Hence, it is necessary to capture current knowledge on the impact of abiotic stress on maize, especially the mechanisms and regulation of maize responses under multiple stresses, and to provide potential solutions that will ensure a sustainable supply of nutritious food to meet the demand from an increasing population under a changing climate.
