This book was released on 2012-06 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yield response of three wheat (Triticum aestivum L.) cultivars (Gemmieza 7, Sakha 93 and Giza 168) to various sowing times was studied during the two 2006/2007 and 2007/2008 seasons. Three sowing dates were 5th November, 20th November, and 5th December. A split-split plot design was used. Wheat plants were sown on 20th November gave the highest values of the most of characteristics such as plant height, leaf area index, crop growth rate, spike length, number of spikes m-2, 1000- kernel weight, grain yield (Mg ha-1), harvest index and protein grains content in both seasons. Increasing N- fertilization rates up to 288 kg N ha-1 led to increased growth parameters, yield and yield components. 288 kg N ha-1 recorded the highest values of the most parameters in both seasons. Gemmieza 7 had highest values for most of growth characters, yield and its components compared with the other cultivars (Sakha 93and Giza 168). Sowing on 20 Nov. with 288 kg N ha-1 had significantly increased on most studied characteristics. There was no fungal diseases infection as affected by different sowing dates and nitrogen fertilization level of the three wheat cultivars during two sowing seasons.

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 Determination of Optimum Fall and Spring Nitrogen Fertilizer Rate for Maximizing Grain Yield of Soft Red Winter Wheat Sown at Variable Planting Dates written by Lucas Vasconselos Vieira and published by . This book was released on 2016 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: An optimum planting date is important for winter wheat nitrogen (N) management as it dramatically changes the growing environment including temperature and moisture, ultimately affecting fertilizer efficiency and grain yield (GY). In Arkansas, high precipitation in the fall often forces farmers to delay planting and current Arkansas recommendations include the application of fall N when soft red winter wheat (SRWW) is sown later than optimum, despite the lack of data supporting this practice. This study evaluated the effect of rate and timing of N application on GY of SRWW sown at variable planting dates in Arkansas. Granular urea was split applied between the fall (F), late winter (LW) and/or early spring (ES) and compared to N only applied in the spring (LW, or LW + ES). Experiments were conducted at the Newport Research Station (NPRS), Pine Tree Research Station (PTRS), and Rohwer Research Station (RWRS), representing the diverse wheat growing regions in Arkansas. Wheat was sown at three planting dates and supplied with total N rates of 67, 101, 135, 169, and 202 kg N ha-1. Fall-N rates equal to 0, 34, 67 kg N ha-1 were applied after planting at Feekes 3 and spring-N rates equal to 67, 101, 135 and 169 kg N ha-1 were applied at Feekes stage 4 or 5. There was no statistical difference between spring (LW and ES) and split N applications at NPRS where there was low precipitation and the highest residual soil-N and thus decreased potential for volatilization and denitrification. A split fall and spring application was important for maximizing GY on the latest planting date at both PTRS and RWRS and increased mean GY by 1122 and 544 kg ha-1 compared to spring only application, respectively. Overall, results suggest that splitting fertilizer-N between fall and spring has the potential for increasing GY in late-planted wheat in fine-textured soils when there is high precipitation, which favors N loss.

Download or read book Agriculture and the Nitrogen Cycle written by Arvin Mosier and published by Island Press. This book was released on 2013-04-10 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is an essential element for plant growth and development and a key agricultural input-but in excess it can lead to a host of problems for human and ecological health. Across the globe, distribution of fertilizer nitrogen is very uneven, with some areas subject to nitrogen pollution and others suffering from reduced soil fertility, diminished crop production, and other consequences of inadequate supply. Agriculture and the Nitrogen Cycle provides a global assessment of the role of nitrogen fertilizer in the nitrogen cycle. The focus of the book is regional, emphasizing the need to maintain food and fiber production while minimizing environmental impacts where fertilizer is abundant, and the need to enhance fertilizer utilization in systems where nitrogen is limited. The book is derived from a workshop held by the Scientific Committee on Problems of the Environment (SCOPE) in Kampala, Uganda, that brought together the world's leading scientists to examine and discuss the nitrogen cycle and related problems. It contains an overview chapter that summarizes the group's findings, four chapters on cross-cutting issues, and thirteen background chapters. The book offers a unique synthesis and provides an up-to-date, broad perspective on the issues of nitrogen fertilizer in food production and the interaction of nitrogen and the environment.
