Available in PDF, EPUB and Kindle. Book excerpt: Insufficient water is the environmental factor most limiting crop productivity in the semi-arid and dry subhumid regions of Saskatchewan. This study was undertaken to establish a framework for the development of winter wheat cultivars which are less sensitive to drought stress. Five winter wheat genotypes, 'Norstar' and 'Norwin' (products of previous breeding efforts) and three more recently selected 'CDC Kestrel-type' advanced Lines were grown in 17 field environments between 1989 and 1991. This study established that the CDC Kestrel-type lines have a higher yield potential and higher average yield than Norstar or Norwin, but they do not differ in yield under most dryland conditions. The yield advantage of the CDC Kestrel type Lines was associated with conditions that favoured the establishment of yield potential. Conversely, the elimination of the CDC Kestrel-type yield advantage was associated with conditions which suppressed the establishment of yield potential. Differences in rainfall, evaporative demand, soil water depletion, evapotranspiration and aerial biomass accumulation during four periods of crop development resulted in three temporal patterns of drought stress: (1) intermittent, (2) terminal and (3) low stress. The environmental effect on grain yield was due to crop water conditions during all development periods. Crop water conditions from heading to anthesis were particularly important to grain yield. Flag leaf water content was positively related to grain yield in the dryland trials. There was no association between aerial biomass at anthesis and grain yield. Both pre- and post-anthesis ET were of similar importance to grain yield. Soil water reserves were depleted by the time the crop had headed in the dryland trials. Consequently, flag leaf water content declined. The distribution of growing season rainfall determined the timing and intensity of drought. A relatively small genotype-environment (GE) interaction for grain yield resulted in a poor co.

Book Synopsis Screening Durum Wheat and Wild Emmer Wheat Germplasm for Drought Tolerance by :
Download or read book Screening Durum Wheat and Wild Emmer Wheat Germplasm for Drought Tolerance written by and published by . This book was released on 1992 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genetic improvement of drought resistance capacity of crop varieties is the only long-term solution to the recurrent drought conditions in Saskatchewan. An integrated approach was adopted to identify genetic sources of drought resistance in wheat, concentrating on durum wheat and its immediate wild relative, wild emmer wheat from West Asia, since most of its growth is in the drought-prone areas. About 5,000 durum and 1,200 wild emmer wheat accessions from diverse origins were evaluated for 28 characters including response to field drought conditions. This report describes the project and the methods involved.

Book Synopsis Toward Sustainable Agricultural Systems in the 21st Century by : National Research Council
Download or read book Toward Sustainable Agricultural Systems in the 21st Century written by National Research Council and published by National Academies Press. This book was released on 2010-07-25 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental, community, labor, and animal welfare standards in agriculture. Toward Sustainable Agricultural Systems in the 21st Century assesses the scientific evidence for the strengths and weaknesses of different production, marketing, and policy approaches for improving and reducing the costs and unintended consequences of agricultural production. It discusses the principles underlying farming systems and practices that could improve the sustainability. It also explores how those lessons learned could be applied to agriculture in different regional and international settings, with an emphasis on sub-Saharan Africa. By focusing on a systems approach to improving the sustainability of U.S. agriculture, this book can have a profound impact on the development and implementation of sustainable farming systems. Toward Sustainable Agricultural Systems in the 21st Century serves as a valuable resource for policy makers, farmers, experts in food production and agribusiness, and federal regulatory agencies.

Book Synopsis Non-Chemical Weed Control by : Khawar Jabran
Download or read book Non-Chemical Weed Control written by Khawar Jabran and published by Academic Press. This book was released on 2018-01-03 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-Chemical Weed Control is the first book to present an overview of plant crop protection against non-food plants using non-chemical means. Plants growing wild—particularly unwanted plants found in cultivated ground to the exclusion of the desired crop—have been treated with herbicides and chemical treatments in the past. As concern over environmental, food and consumer safety increases, research has turned to alternatives, including the use of cover crops, thermal treatments and biotechnology to reduce and eliminate unwanted plants. This book provides insight into existing and emerging alternative crop protection methods and includes lessons learned from past methodologies. As crop production resources decline while consumer concerns over safety increase, the effective control of weeds is imperative to insure the maximum possible levels of soil, sunlight and nutrients reach the crop plants. Allows reader to identify the most appropriate solution based on their individual use or case Provides researchers, students and growers with current concepts regarding the use of modern, environment-friendly weed control techniques Presents methods of weed management—an important part of integrated weed management in the future Exploits the knowledge gained from past sustainable weed management efforts

Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1990, this book analysed the sensitivity of the world food system and looked at the variety of ways in which it would be affected by climate change. It describes the effects of climate change on agriculture, estimates the impacts on plant and animal growth and looks at the geographical limits to different types of farming.

Download or read book The State of the World's Land and Water Resources for Food and Agriculture written by Food and Agriculture Organization of the United Nations and published by Routledge. This book was released on 2013-06-17 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The State of the World's Land and Water Resources for Food and Agriculture is FAO's first flagship publication on the global status of land and water resources. It is an 'advocacy' report, to be published every three to five years, and targeted at senior level decision makers in agriculture as well as in other sectors. SOLAW is aimed at sensitizing its target audience on the status of land resources at global and regional levels and FAO's viewpoint on appropriate recommendations for policy formulation. SOLAW focuses on these key dimensions of analysis: (i) quantity, quality of land and water resources, (ii) the rate of use and sustainable management of these resources in the context of relevant socio-economic driving factors and concerns, including food security and poverty, and climate change. This is the first time that a global, baseline status report on land and water resources has been made. It is based on several global spatial databases (e.g. land suitability for agriculture, land use and management, land and water degradation and depletion) for which FAO is the world-recognized data source. Topical and emerging issues on land and water are dealt with in an integrated rather than sectoral manner. The implications of the status and trends are used to advocate remedial interventions which are tailored to major farming systems within different geographic regions.
