Book Description
Weather during the growing season is critical for corn and soybean yields. Adjusting for weather in an analysis of historical U.S. corn and soybean yields is important for determining underlying trends and future yield expectations. Models for U.S. corn and soybean yields provide estimates of the effects of weather on yields for those crops, allowing an analysis of those effects to be used to derive weather-adjusted trend yields. The corn model also includes planting progress by the middle of May. The estimated models indicate that reductions in precipitation below its average result in larger declines in yields than the gains in yields resulting from increases in precipitation of equal magnitudes above its average. The yield models are used to track effects of high temperatures and drought on U.S. corn and soybean yields in 2012 and to provide estimates for expected 2013 yields. Further, the models provide a framework for assessing changes in expected yields due to planting progress and weather developments. Figures and tables. This is a print on demand report.

Response of Crops to Limited Water
Author: Lajpat AhujaPublisher: ASA-CSSA-SSSA
ISBN: 9780891181675
Category : Science
Languages : en
Pages : 456
Book Description
Water stress and heat stress are considered to be two primary factors that limit crop production in many parts of the world. Global warming appears to be increasing the water requirements of plants. Understanding the impact of water deficit on plant physiological processes and efficient water management are of great concern in maintaining food production to meet ever increasing world food demand. The book addresses various climatic soil and plant factors that contribute to the water use efficiency in plants subjected to water stress. It covers all issues related to soil, plant and climatic factors that contribute to the crop responses to water stress. The books advances the knowledge in improving and sustaining crop yields in ever increasing unpredictable climatic fluctuations This book uses crop simulation models for response of crops to limited water under various management and climatic conditions.
Review of the Draft Fourth National Climate Assessment

ISBN: 0309471699
Category : Science
Languages : en
Pages : 207
Book Description
Climate change poses many challenges that affect society and the natural world. With these challenges, however, come opportunities to respond. By taking steps to adapt to and mitigate climate change, the risks to society and the impacts of continued climate change can be lessened. The National Climate Assessment, coordinated by the U.S. Global Change Research Program, is a mandated report intended to inform response decisions. Required to be developed every four years, these reports provide the most comprehensive and up-to-date evaluation of climate change impacts available for the United States, making them a unique and important climate change document. The draft Fourth National Climate Assessment (NCA4) report reviewed here addresses a wide range of topics of high importance to the United States and society more broadly, extending from human health and community well-being, to the built environment, to businesses and economies, to ecosystems and natural resources. This report evaluates the draft NCA4 to determine if it meets the requirements of the federal mandate, whether it provides accurate information grounded in the scientific literature, and whether it effectively communicates climate science, impacts, and responses for general audiences including the public, decision makers, and other stakeholders.
Mid-Atlantic Corn and Soybean Yields Show Great Variability in Response to Precipitation During Critical Growth Stages
Author: Michel A. CavigelliPublisher:
ISBN:
Category : Corn
Languages : en
Pages : 2
Book Description
The mid-Atlantic coastal plain, where the FSP is located, has higher than average variability in corn and soybean yields compared to the most productive agricultural regions in the US. Precipitation is the primary driver of crop yield variability in this region and drought is often responsible for low yields.

Understanding Options for Agricultural Production
Author: G.Y. TsujiPublisher: Springer Science & Business Media
ISBN: 9401736243
Category : Science
Languages : en
Pages : 405
Book Description
The first premise of this book is that farmers need access to options for improving their situation. In agricultural terms, these options might be manage ment alternatives or different crops to grow, that can stabilize or increase household income, that reduce soil degradation and dependence on off-farm inputs, or that exploit local market opportunities. Farmers need a facilitating environment, in which affordable credit is available if needed, in which policies are conducive to judicious management of natural resources, and in which costs and prices of production are stable. Another key ingredient of this facilitating environment is information: an understanding of which options are viable, how these operate at the farm level, and what their impact may be on the things that farmers perceive as being important. The second premise is that systems analysis and simulation have an impor tant role to play in fostering this understanding of options, traditional field experimentation being time-consuming and costly. This book summarizes the activities of the International Benchmark Sites Network for Agrotechnology Transfer (IBSNAT) project, an international initiative funded by the United States Agency for International Development (USAID). IBSNAT was an attempt to demonstrate the effectiveness of understanding options through systems analysis and simulation for the ultimate benefit of farm households in the tropics and subtropics. The idea for the book was first suggested at one of the last IBSNAT group meetings held at the University of Hawaii in 1993.

Effects of Climate Change on Agriculture, Land Resources, Water Resources, and Biodiversity in the United States
Author: Peter BacklundPublisher: DIANE Publishing
ISBN: 143791098X
Category : Science
Languages : en
Pages : 250
Book Description
This report by the Nat. Science and Tech. Council¿s U.S. Climate Change Science Program (CCSP) is part of a series of 21 reports aimed at providing current assessments of climate change science to inform public debate, policy, and operational decisions. These reports are also intended to help the CCSP develop future program research priorities. The CCSP¿s guiding vision is to provide the Nation and the global community with the science-based knowledge needed to manage the risks and capture the opportunities associated with climate and related environmental changes. This report assesses the effects of climate change on U.S. land resources, water resources, agriculture, and biodiversity. It was developed with broad scientific input. Illus.
