Book Synopsis Crop Evolution, Adaptation and Yield by : L. T. Evans
Download or read book Crop Evolution, Adaptation and Yield written by L. T. Evans and published by Cambridge University Press. This book was released on 1996-05-02 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this major 1993 work, Lloyd Evans provides an integrated view of the domestication, adaptation and improvement of crop plants, bringing together genetic diversity, plant breeding, physiology and aspects of agronomy. Considerations of yield and maximum yield provide continuity throughout the book. Food, feed, fibre, fuel and pharmaceutical crops are all discussed. Cereals, grain legumes and root crops, both temperate and tropical, provide many of the examples, but pasture plants, oilseeds, leafy crops, fruit trees and others are also considered. After the introductory chapter, the increasing significance of crop yields to the world's food supply is highlighted. The next three chapters consider changes to crop plants over the last ten thousand years, including domestication, adaptation and improvement. Aimed at research workers and advanced students in crop physiology and ecology, agronomy and plant breeding, this book also reaches conclusions of relevance to those concerned with developmental policy, agricultural research and management, environmental quality, resource depletion and human history.

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.

Book Synopsis By-plant Sidedress Nitrogen in Corn (Zea Mays L.) Based on Plant Height and Normalized Difference Vegetation Index by : Jeremiah Lee Mullock
Download or read book By-plant Sidedress Nitrogen in Corn (Zea Mays L.) Based on Plant Height and Normalized Difference Vegetation Index written by Jeremiah Lee Mullock and published by . This book was released on 2012 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current methods of applying nitrogen (N) fertilizer do not treat small scale variability that is known to exist. Variations in corn grain yield can be found from one plant to the next. With knowledge that yield potential can be predicted by-plant, this in turn can be used to adjust fertilizer N rates for individual plants. This study was conducted in 2010 and 2011 to evaluate by-plant sidedress N using plant height and normalized difference vegetation index (NDVI) sensor readings. Treatments included preplant N rates of 0, 45, 90, and 180 kg N ha-1 with 180 kg N ha-1 as a reference strip. Sidedress N was applied as a variable rate on a by-plant basis, uniform rate on a by-plant basis, and uniform rate on the entire row with a non-fertilized check included. By-plant sidedress N applications increased yields when the preplant N rate was optimized. When preplant N rates exceeded the optimum needed for maximum grain yields, no benefits of by-plant N fertilization were observed.
Book Synopsis Fertilizers Boost Yields of Small Grains, Grasses and Legumes by : Lewis Bailey Nelson
Download or read book Fertilizers Boost Yields of Small Grains, Grasses and Legumes written by Lewis Bailey Nelson and published by . This book was released on 1949 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Corn is king in Iowa. But corn should not be grown continuously. It should be rotated with small grains, clover or alfalfa. Such a rotation insures a good nitrogen level in the soil, cuts down on erosion, and helps keep the soil in good tilth. These factors in turn result in higher corn yields. Too often we neglect or omit our small grains and seedings because they don't give us the high cash return of corn.One way to make them more profitable is to increase their yields. You can give the yields a real boost with fertilizers. There are two ways to use fertilizers on small grains and forages, the right and the wrong. Among other things, the right way involves using the correct kind and amount of fertilizer, applying it effectively to the soil at the best time. You must know how to do these things. They will determine the returns you will get from your fertilizer. To give you the best possible information on these points, the Iowa Agricultural Experiment Station has conducted several hundred experiments on the fields over the state during the past few years.It is the purpose of this bulletin to give you the information gathered from these experiments along with the other points to help you in your fertilizer." -- p.

Book Synopsis Nitrogen Use and Behavior in Crop Production by : L. Fred Welch
Download or read book Nitrogen Use and Behavior in Crop Production written by L. Fred Welch and published by . This book was released on 1979 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most plants absorbmore nitrogen than any other nutrient. Because the amount needed is so large and easily be lost from many soils, nitrogen is usually the most limiting nutrient for plant growth. Although about 79 percent of the atmosphere is nitrogen, only nitrogen-fixingplants such as legumeswith their associated bacteria are able to use this abundant source. The nonleguminous grain crops must receive supplemental nitrogen to produce satisfactory yields. Until the last few decades the supply of available nitrogen in the soil was increased primarily by legumes and manure. These sources should be used when economically feasible, but many important grain-producing areas of the world must now rely on commercial fertilizer nitrogen. For economic reasons researchers and growers have been interested for many years in improving yields from each unit of nitrogen. Recently, however, the efficient use of nitrogen has become an environmental issue as well, because high nitrate concentrations in water may be harmful to humans, especiali infants, and to livestock. If plants absorb more of the addedfertilizer nitrogen, then less is likely to leach from fields into drinking water. Improving nitrogen efficiency has also become crucial in order to conserve dwinling supplies of natural gas, which is used in large quantities to manufacture nitrogenfertilizers.
