Book Synopsis Improving Modeling Tools to Assess Climate Change Effects on Crop Response by : Jerry L. Hatfield
Download or read book Improving Modeling Tools to Assess Climate Change Effects on Crop Response written by Jerry L. Hatfield and published by John Wiley & Sons. This book was released on 2020-01-22 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crop model intercomparison and improvement are required to advance understanding of the impact of future climate change on crop growth and yield. The initial efforts undertaken in the Agriculture Model Intercomparison and Improvement Project (AgMIP) led to several observations where crop models were not adequately simulating growth and development. These studies revealed where enhanced efforts should be undertaken in experimental data to quantify the carbon dioxide × temperature × water interactions in plant growth and yield. International leaders in this area held a symposium at the 2013 ASA, CSSA, and SSSA Annual Meeting to discuss this topic. This volume in the Advances in Agricultural Systems Modeling series presents experimental observations across crops and simulation modeling outcomes and addresses future challenges in improving crop simulation models. IN PRESS! This book is being published according to the “Just Published” model, with more chapters to be published online as they are completed.
Book Synopsis Modeling Crop Response to Nitrogen by : Nanchang Yang

Book excerpt: These index values also tended to linearly relate to rates of N fertilization and were found to be very useful for identifying optimal rates of N fertilization. The concentration of nitrate required to attain the optimal N-sufficiency level in the crop was surprisingly stable across sites. Analyses showed that relationships between the index values and soil nitrate concentrations or rates of fertilization offer great potential as a tool to aid in explanation of data collected in N response trials or in interpretation of stalk nitrate concentrations in cornfields. More studies are needed to fully explore the potential and limitations of the new index.

Available in PDF, EPUB and Kindle. Book excerpt: Crop Responses to Environment discusses the principles, theories, and experimental observations concerning plant responses to environment that are particularly relevant to developing improved crop cultivars and management methods. The book illustrates the importance of considering emergent plant properties as well as reductionist approaches to understanding plant function and adaptation. Dr. Hall explains many practical applications to plant breeding, agronomy, and horticulture. He examines plant physiological and developmental responses to light and temperature as well as plant water-relations. He also describes climatic zone definitions based on temperature, rainfall, and evaporative demand in relation to plant adaptation and the prediction of crop water use. Irrigation management and crop responses to salinity and toxic levels of boron and aluminum are considered. Numerous figures and tables illustrate the climates of major agricultural zones, giving a thorough knowledge of which crop species and production systems are effective in different climates. The book concludes with an analysis illustrating the relevance of crop responses to environment to plant breeding. The practical examples in this book, some of them pulled from Dr. Hall's research, show your students the principles provided by Crop Response to Environment can be used in developing improved crop production systems.
Book Synopsis Extended Logistic Model of Crop Response to Applied Nutrients by : Kelly Hans Brock
Download or read book Extended Logistic Model of Crop Response to Applied Nutrients written by Kelly Hans Brock and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The overall intent of this research was to lend further insight into the ELM and bring it one step closer to efficacy for practical use by engineers, especially by searching for patterns in each of its five parameters and comparing results to previous findings. The research reaffirmed that the ELM is a consistently good descriptor of crop response to applied N. Results also suggested that the parameter N sub cl, the lower theoretical plant N concentration limit, is a strong function of crop type as has been found in previous studies and is affected little by water availability or fertilizer source.

Crop responses to pests and diseases as they interact with crop responses to physical and chemical aspects of the environment are examined. The book concludes with analyses illustrating the relevance of crop responses to environment to plant breeding.
Book Synopsis The Analysis of Response in Crop and Livestock Production by : John L. Dillon
Download or read book The Analysis of Response in Crop and Livestock Production written by John L. Dillon and published by Elsevier. This book was released on 2012-12-02 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of the agricultural scientist is to manipulate crop and livestock response phenomena so that they serve society's needs better, enabling countries to obtain full benefit from their agricultural resources. By producing food more efficiently, resources can be made available for non-agricultural development and other needs beyond the essentials of food and fibre. This text provides an introductory outline of the analytical principles involved in appraising the efficiency of crop-fertilizer and livestock-feed response. It provides students of both agricultural science and economics with a simple but formal exposition of the why, how and wherefore of the principles of crop and livestock analysis, thereby helping to further co-operative effort among biological and economic researchers. The third edition has been updated and revised, with additions relating to the principles of modelling, the concept of economic duality as pertinent to response processes, the appraisal of aggregate response, and the economics of response research.
Download or read book Sulphur in Plants written by Y.P. Abrol and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sulphur (S) plays a pivotal role in various plant growth and development processes being a constituent of sulphur-containing amino acids, cysteine and methionine, and other metabolites viz., glutathione and phytochelatins, co-factor of enzymes which contribute to stress repair and amelioration of heavy metal toxicity. Besides, a number of S-containing components are biologically active and, thus, a source for use as medicinal value. The basic global issue before the agricultural scientist and world community is to evolve cultivars and develop methodologies for efficient use of inputs to enhance agricultural productivity. This is particularly true of the developing countries which are going to see maximum rise in population with changing food demands and declining availability of land. Amongst the inputs, nutrients play a crucial role. The major requirement is for N, P and K followed by several micro-nutrients. In this context reports of world-wide S deficiency in the agricultural systems are relevant. The reasons are many. Broadly speaking reduction inS emission, use of S-free N, P and K fertilizers and higher biomass production contributed the maximum. Despite the need for sulphur as an essential plant nutrient and the substantial returns expected from its use, very little attention has been given to fill the gap between supply and demand of S.

Book Synopsis Impacts of Global Change on the Hydrological Cycle in West and Northwest Africa by : Peter Speth
Download or read book Impacts of Global Change on the Hydrological Cycle in West and Northwest Africa written by Peter Speth and published by Springer Science & Business Media. This book was released on 2010-08-12 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa is highly vulnerable to the impacts of climate change. In particular shortage of fresh water is expected to be the dominant water problem for West and Northwest Africa of the 21th century. In order to solve present and projected future problems concerning fresh water supply, a highly interdisciplinary approach is used in the book. Strategies are offered for a sustainable and future-oriented water management. Based on different scenarios, a range of management options is suggested with the aid of Information Systems and Spatial Decision Support Systems for two river catchments in Northwest and West Africa: the wadi Drâa in south-eastern Morocco and the Ouémé basin in Benin. The selected catchments are representative in the sense: "what can be learnt from these catchments for other similar catchments?
Book Synopsis Crop Responses and Adaptations to Temperature Stress by : Amarjit Basra
Download or read book Crop Responses and Adaptations to Temperature Stress written by Amarjit Basra and published by CRC Press. This book was released on 2023-04-28 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examine the ways in which various plants respond when exposed to high and low temperatures! The growing demand for food makes breeding for high-yielding crops with built-in resistance against environmental constraints one of the most important challenges for plant breeders today. Crop Responses and Adaptations to Temperature Stress investigates the adaptive mechanisms plants have evolved in response to unfavorable temperature conditions. It describes gene transfer technology and other tolerance improvement techniques that aid in developing stress-tolerant plants. Adverse environmental stress conditions, such as extreme temperatures, affect the productivity of important world food crops by inhibiting plant growth and development. Crop Responses and Adaptations to Temperature Stress provides valuable information on the mechanisms of stress tolerance in plants that encourage growth and enhance yield performance. Agriculture professionals, researchers, and plant breeders will benefit from the ideas shared on such topics as: mechanisms of chilling injury and tolerance injury and acclimation of root system functions during chilling temperatures mechanisms of cold acclimation signal transduction under low-temperature stress mechanisms of thermotolerance in crops control of the heat shock response in crop plants the effects of heat stress on cereal yield and quality Crop Responses and Adaptations to Temperature Stress presents detailed discussions on the effects and outcomes of crop exposure to low and high temperatures. The textual information is liberally supplemented with visual representations of field experiment data as well as comprehensive tables and schematic drawings. In addition to a detailed review of current knowledge on the molecular biology of plant responses to temperature stress and an introduction to biotechnological advances in improving crop tolerance, Crop Responses and Adaptations to Temperature Stress suggests avenues for further study and speculates on the implications of such work for the future of food production.

Book Synopsis Crop Responses to Global Warming by : Dinesh Chandra Uprety
Download or read book Crop Responses to Global Warming written by Dinesh Chandra Uprety and published by Springer. This book was released on 2016-09-13 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: The monograph entitled “Crop responses to Global warming” describes the normal historical shifts in the earth’s atmospheric temperature and weighs the evidence concerning anthropogenic induced changes in the level of temperature. The unprecedented increase in the earth’s temperature after pre industrial period has been possibly related to the anthropogenic activities. This monograph will give an overview of the global as well as Indian crops productivity in relation to the rise in the earth’s surface temperature. A chapter in this monograph is on the technologies to study the response of crop plants to the elevated temperature. The impact assessment analysis of rising temperature on crops such as wheat, rice, maize, soybean, cotton and brassica are described, reviewed and discussed in separate chapters as case studies. The responses of physiological processes and biochemical reactions to the elevated temperature in crop plants are described crop wise. The monograph also includes the impact of elevating temperature on crop weed interaction, pest and diseases and soil dynamics for each crop species independently. The mitigation technologies to counter the adverse effect of high temperature stress are described for each crop according to their cultivation and climatic conditions. The future research strategies for each crop to meet the threat of elevating temperature on crop productivity and food security is described and discussed. The description of temperature enrichment technologies will help researchers and scientists to study the responses of biological materials to rising temperature. The monograph will be the main text for teaching climate change, global warming and environmental botany as no such book is currently available relating to the rising atmospheric temperature on crop plants. Therefore, the monograph will be highly useful for students of global climate change, environmental botany and agricultural sciences, scientists, researchers, farmers and policy makers
Book Synopsis Crop Physiology Case Histories for Major Crops by : Victor Sadras
Download or read book Crop Physiology Case Histories for Major Crops written by Victor Sadras and published by Academic Press. This book was released on 2020-12-05 with total page 780 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crop Physiology: Case Histories of Major Crops updates the physiology of broad-acre crops with a focus on the genetic, environmental and management drivers of development, capture and efficiency in the use of radiation, water and nutrients, the formation of yield and aspects of quality. These physiological process are presented in a double context of challenges and solutions. The challenges to increase plant-based food, fodder, fiber and energy against the backdrop of population increase, climate change, dietary choices and declining public funding for research and development in agriculture are unprecedented and urgent. The proximal technological solutions to these challenges are genetic improvement and agronomy. Hence, the premise of the book is that crop physiology is most valuable when it engages meaningfully with breeding and agronomy. With contributions from 92 leading scientists from around the world, each chapter deals with a crop: maize, rice, wheat, barley, sorghum and oat; quinoa; soybean, field pea, chickpea, peanut, common bean, lentil, lupin and faba bean; sunflower and canola; potato, cassava, sugar beet and sugarcane; and cotton. A crop-based approach to crop physiology in a G x E x M context Captures the perspectives of global experts on 22 crops
