Available in PDF, EPUB and Kindle. Book excerpt: Wheat breeders have achieved significant results over the last fifty years in research on mankind's one of the most important crops. Classical genetic and breeding methods, far broader international cooperation than was experienced in earlier periods, and improvements in agronomic techniques have led to previously unimaginable development in the utilisation of wheat for human consumption. The contribution of wheat researchers is particularly noteworthy since these results have been achieved at a time when the world population has grown extremely dynamically. Despite this demographic explosion, of a proportion never previously experienced, thousands of millions of people have been saved from starvation, thus avoiding unpredictable social consequences and situations irreconcilable with human dignity. Despite these developments in many regions of the world food supplies are still uncertain and the increase in the world's wheat production has not kept pace with the population increase during the last decade. Due to the evils of civilisation and the pollution of the environment there is a constant decline in the per capita area of land suitable for agricultural production. Based on population estimates for 2030, the present wheat yield of around 600 million tonnes will have to be increased to almost 1000 million tonnes if food supplies are to be maintained at the present level.

Download or read book Effect of Elevated Carbon Dioxide on Nitrogen Nutrition in Wheat written by S. Lekshmy and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Availability of nitrogen (N) is a critical factor determining plant responses to high CO2. Elevated CO2 affects N metabolism, depending on the nitrogen source. However limited information is available on how various forms of N affects morphology and metabolism of plant under elevated CO2. Similarly elevated CO2 induces changes in stomatal and epidermal parameters in plants. Different N forms had profound effects on morphology both under ambient CO2 and elevated CO2. The negative effects of ammonium nutrition were manifested as reduction in root length, root surface area, chlorophyll a: b ratio, and thinner leaves, in elevated CO2 also. When ammonium nutrition was supplemented with nitrate ions, enhancement of various morphological, biochemical and anatomical parameters was more in ECO2 than when only nitrate was given. Hence supplimenting nitrate nutrition with ammonium ions might be beneficial for wheat under elevated CO2 conditions in future

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nitrogen uptake of organically selected and conventional spring wheat cultivars was assessed throughout the growing season. High protein yielding advanced lines were selected from the Agriculture and Agri-Food Canada and the University of Manitoba's joint organic breeding program. The organic breeding lines were compared with conventional check cultivars. The organic lines were found to have higher average yield, grain N yield, kernel density, HI, and NHI while the check cultivars were found to have higher average grain protein. No significant differences were observed between organic lines and the check cultivars for biomass and N biomass accumulation. The strong performance of the organic breeding lines compared to their conventional counterparts for several key parameters is a positive indication of the benefits of specialized breeding programs. The higher yield of the organic lines indicated that they were better able to cope with the environmental stresses associated with organic growing conditions.

Book excerpt: Between 1958 and 2008, the CO2 concentration in the atmosphere increased from 316 to 385 ppm. Continued increases in CO2 concentration will significantly affect long-term climate change, including variations in agricultural yields. Focusing on this critical issue, Elevated Carbon Dioxide: Impacts on Soil and Plant Water Relations presents research

Book excerpt: Since photosynthetic performance is a fundamental determinant of yield in the vast majority of crops, an understanding of the factors limiting photosynthetic productivity has a crucial role to play in crop improvement programmes. Photosynthesis, unlike the majority of physiological processes in plants, has been the subject of extensive studies at the molecular level for many years. This reductionist approach has resulted in the development of an impressive and detailed understanding of the mechanisms of light capture, energy transduction and carbohydrate biosynthesis, processes that are clearly central to the success of the plant and the productivity of crops. This volume examines in the widest context the factors determining the photosynthetic performance of crops. The emphasis throughout the book is on the setting for photosynthesis rather than the fundamental process itself. The book will prove useful to a wide range of plant scientists, and will encourage a more rapid integration of disciplines in the quest to understand and improve the productivity of crops by the procedures of classical breeding and genetic manipulation.

Download or read book Crop Production and Global Environmental Issues written by Khalid Rehman Hakeem and published by Springer. This book was released on 2015-12-08 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meeting the world’s food security challenge will require a multi-national, collaborative effort to integrate the best research from science, engineering and socioeconomics so that technological advances can bring benefits where they are most needed. The present book covers the effect of major environmental problems on crop production and how to cope with these issues for sustainable agriculture and improvements of crops. The world’s population is predicted to hit 9.6 Billion by 2050, up from today’s total of nearly 7.3 Billion, and with it food demand is predicted to increase substantially. The post-war ‘second agricultural revolution’ in developed countries, and the ‘green revolution’ in developing nations in the mid- 1960s converted agricultural practices and elevated crop yields spectacularly, but the outcome is levelling off and will not meet projected demand. Simultaneously, crop production is affected by many other factors, including industrial pollution, overuse of fertilizers and insecticides, heavy metal and radiation stresses etc. It has been noted that many pests are becoming resistant to insecticides. Estimates vary, but around 25% of crops can be lost to pests and diseases. Climate change associated with agriculture is also a global issue. Agriculture is a significant contributor to greenhouse gases and is estimated to account for 10-12% of total greenhouse gas (GHG) emissions. Many of the issues highlighted are global problems and are addressed thoroug hly in this work.

This book was released on 1991-02-01 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question of whether the earth's climate is changing in some significant human-induced way remains a matter of much debate. But the fact that climate is variable over time is well known. These two elements of climatic uncertainty affect water resources planning and management in the American West. Managing Water Resources in the West Under Conditions of Climate Uncertainty examines the scientific basis for predictions of climate change, the implications of climate uncertainty for water resources management, and the management options available for responding to climate variability and potential climate change.
