Book excerpt: Cereal Grains: Assessing and Managing Quality, Second Edition, provides a timely update to this key reference work. Thoroughly revised from the first edition, this volume examines the latest research and advances in the field. New chapters have been added on alternative grains, including ancient grains and pseudocereals, biosecurity, and industrial processing of grains, amongst others. Quality and food safety are important throughout the value-addition chain, from breeding, production, harvest, storage, transport, processing, and marketing. At all stages, analysis is needed so that quality management can proceed intelligently. These considerations are examined for each of the major cereal species, including wheat (common and durum), rye and triticale, barley and oats, rice, maize (corn), pseudocereal species, sorghum, and the millets. Divided into five sections, the book analyses these for the range of cereal species before a final section summarizes key findings. - Documents the latest research in cereal grains, from their nutraceutical and antioxidant traits, to novel detection methods - Provides a complete and thorough update to the first edition, analyzing the range of major cereal species - Presents detailed advice on the management of cereal quality at each stage of production and processing
Download or read book Effect of Nitrogen Fertilization of Wheat Triticum Spp on Chemical and Biochemical Composition and Performance of Seeds written by Adriel Edgardo Garay and published by . This book was released on 1975 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: High protein wheat seeds frequently perform better than low protein seeds of the same variety. Protein content of seeds can be increased by management practices, the most important of which is rate and timing of N applications. The purpose of this study was to determine the chemical, biochemical and physiological changes that occur in seeds as a result of nitrogen fertilization, and to relate these changes to seed performance. Seeds of Yamhill, Paha and Hyslop soft white winter wheat were produced with N applications of 0 to 450 kg/ha. Applications were made at planting, flower initiation, and anthesis. Supplemental irrigation was supplied. Applications of 150 and 300 kg N /ha increased the grain yield and protein yield per hectare, seed size, and percent and amount of protein per seed of Yamhill wheat. N applications caused several biochemical changes in the food reserve of the seeds. These included increases in the amounts of gluten, each amino acid studied and free amino acids. The amount of soluble sugars decreased slightly and starch remained constant with high rates of N.N also caused several biochemical changes in embryos. These included increases in: free amino acids and soluble sugars; protein concentrations and amount per embryo; ADP, ATP and energy charge. Regardless of protein concentration, the quantities of solubles and adenylate phosphates were higher in larger embryos. Biochemical changes in seedlings associated with N applications and higher protein content included: more sugars and free amino acids; higher amounts of ATP, ADP and total AP; and faster rate and higher net translocation of food reserves. Small seeds contained a higher concentration of ash, some mineral elements, soluble sugars and free amino acids. The total amount of these compounds per seed, however, was related to protein content and seed size. The large seeds with high protein concentration produced seedlings with the highest ADP, ATP and total AP content, energy charge and growth potential. Smaller seeds absorbed water and germinated faster than larger seeds. Seedlings from small seeds produced longer roots and shoots during the early stages of growth, but their growth rate was slower at later stages. High protein seeds of Hyslop, Paha and Yamhill outyielded low protein seeds by 12 to 17%. Yield differences were obtained when N was added to the crop, but not in the absence of added N. These and other studies indicate the potential for improving wheat seed and quality by applying specialized management practices for seed production rather than managing for grain production.

This book was released on 2022-06-07 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable Crop Productivity and Quality under Climate Change: Responses of Crop Plants to Climate Change explores the physiological, biochemical, and molecular basis of the responses of major crop plants to a range of climate change scenarios. From the development of climate-resilient crop varieties which lead to enhanced crop productivity and quality to better utilization of natural resources to ensure food security through modern breeding techniques, it presents insights into improving yield while securing the environment. Understanding the impact of climate on crop quality and production is a key challenge of crop science. Predicted increases in climate variability necessitate crop varieties with intrinsic resilience to cooccurring abiotic stresses such as heat, drought, and flooding in a future climate of elevated CO2. This book presents a much-needed mechanistic understanding of the interactions between multiple stress responses of plants that is required to identify and take advantage of acclimation traits in major crop species as a prerequisite for securing robust yield and good quality. This book is an excellent reference for crop and agricultural scientists, plant scientists, and researchers working on crop plant ecophysiology/stress physiology and future crop production. - Includes breeding strategies for developing climate-resilient crop varieties - Presents a comprehensive overview of the current challenges, approaches, and best practices - Authored by frontline researchers and experts who work at the fields of climate change impacts on crop productivity

Available in PDF, EPUB and Kindle. Book excerpt: Global crop production must substantially increase to meet the needs of a rapidly growing population. This is constrained by the availability of nutrients, water, and land. There is also an urgent need to reduce the negative environmental impacts of crop production. Collectively, these issues represent one of the greatest challenges of the twenty-first century. Sustainable cropping systems based on ecological principles are the core of integrated approaches to solve this critical challenge. This special issue provides an international basis for revealing the underlying mechanisms of sustainable cropping systems to drive agronomic innovations. It includes review and original research articles that report novel scientific findings on improvement in cropping systems related to crop yields and their resistance to biotic and abiotic stressors, resource use efficiency, environmental impact, sustainability, and ecosystem services.

Available in PDF, EPUB and Kindle. Book excerpt: Agronomic crops have been a source of foods, beverages, fodders, fuels, medicines and industrial raw materials since the dawn of human civilization. Over time, these crops have come to be cultivated using scientific methods instead of traditional methods. However, in the era of climate change, agronomic crops are increasingly subjected to various environmental stresses, which results in substantial yield loss. To meet the food demands of the ever-increasing global population, new technologies and management practices are being adopted to boost yield and maintain productivity under both normal and adverse conditions. To promote the sustainable production of agronomic crops, scientists are currently exploring a range of approaches, which include varietal development, soil management, nutrient and water management, pest management etc. Researchers have also made remarkable progress in developing stress tolerance in crops through various approaches. However, finding solutions to meet the growing food demands remains a challenge. Although there are several research publications on the above-mentioned problems, there are virtually no comprehensive books addressing all of the recent topics. Accordingly, this book, which covers all aspects of production technologies, management practices, and stress tolerance of agronomic crops in a single source, offers a highly topical guide.

Download or read book Effect of Droplet Size and Nitrogen Rate on Protein Content of Hard Red Winter Wheat Triticum Aestivum L written by Ethan Cord Wyatt and published by . This book was released on 2013 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: In past years, grain protein concentration (GPC) has been highly variable from one location to the next. Many factors, environmental and genetic, contribute to the percent protein levels in the grain (Kramer, 1978). Along with increasing prices of inputs (land prices, machinery, fertilizer, and seed) producers continually need to adopt more efficient practices to ensure that GPC is at adequate levels so as to avoid potential dockage and/ or realize potential premiums. This study was conducted to determine the effect of droplet size and late-season nitrogen application on grain protein concentration. The effects of late season foliar N applications (post-anthesis) and droplet size on protein concentration were investigated on hard red winter wheat (Triticum aestivum L.) at three winter wheat sites in Oklahoma, Efaw (Stillwater), Lake Carl Blackwell, and Perkins. Foliar N was applied at two rates 11.2 and 22.4 kg ha−1 with three different droplet sizes per N rate; the 11.2 kg ha−1 N rate consisting of an adjuvant tank-mixed treatment and a non-adjuvant treatment. For most locations and years grain protein concentration was increased linearly with higher rates of foliar N applied. Use of the fine droplet size with a foliar N rate of 11.2 kg N ha−1 applied post anthesis and with the addition of an adjuvant resulted in the highest grain protein concentration.
