This book was released on 2024-05-22 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: The improvement in global crop production over the past several decades has been associated with increased use of nitrogen (N) fertilizer. However, on average, less than 50% of the nitrogen added to croplands globally is harvested as crop product. Inefficient use of N fertilizer by crops will result in substantial agricultural nitrogen losses, posing threats to human and ecosystem health. Crop production must increase dramatically to meet the growing demand for food and biofuels projected for 2050. To boost crop yield with lowered environmental cost, the use of high-potential crop cultivars and efficient nitrogen fertilizer management are required. Recent advances in N management practices, such as enhanced-efficiency fertilizer use, improved manure management and machine deep placement of fertilizer have opened up new strategies to achieve improved crop production with N use reduction. A better understanding of the key crop traits and regulatory processes in response to N fertilizer managements will facilitate the increase in crop yield, N use efficiency while minimizing impacts on the environment.

Book excerpt: From climate change to farming systems to genetic modification of organisms, Crop Physiology, Second Edition provides a practical tool for understanding the relationships and challenges of successful cropping. With a focus on genetic improvement and agronomy, this book addresses the challenges of environmentally sound production of bulk and quality food, fodder, fiber, and energy which are of ongoing international concern. The second edition of Crop Physiology continues to provide a unique analysis of these topics while reflecting important changes and advances in the relevant science and implementation systems. Contemporary agriculture confronts the challenge of increasing demand in terms of quantitative and qualitative production targets. These targets have to be achieved against the background of soil and water scarcity, worldwide and regional shifts in the patterns of land use driven by both climate change and the need to develop crop-based sources of energy, and the environmental and social aspects of agricultural sustainability. - Provides a view of crop physiology as an active source of methods, theories, ideas, and tools for application in genetic improvement and agronomy - Written by leading scientists from around the world - Combines environment-specific cropping systems and general principles of crop science to appeal to advanced students, and scientists in agriculture-related disciplines, from molecular sciences to natural resources management

Book excerpt: Efforts to increase efficient nutrient use by crops are of growing importance as the global demand for food, fibre and fuel increases and competition for resources intensifies. The Molecular and Physiological Basis of Nutrient Use Efficiency in Crops provides both a timely summary of the latest advances in the field as well as anticipating directions for future research. The Molecular and Physiological Basis of Nutrient Use Efficiency in Crops bridges the gap between agronomic practice and molecular biology by linking underpinning molecular mechanisms to the physiological and agronomic aspects of crop yield.

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.

Book excerpt: Climate change is expected to have a drastic impact on agronomic conditions including temperature, precipitation, soil nutrients, and the incidence of disease pests, to name a few. To face this looming threat, significant progress in developing new breeding strategies has been made over the last few decades. The first volume of Genomics and Breeding for Climate-Resilient Crops presents the basic concepts and strategies for developing climate-resilient crop varieties. Topics covered include: conservation, evaluation and utilization of biodiversity; identification of traits, genes and crops of the future; genomic and molecular tools; genetic engineering; participatory and evolutionary breeding; bioinformatics tools to support breeding; funding and networking support; and intellectual property, regulatory issues, social and political dimensions.

This book was released on 1999 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rotating wheat with other crops is a common practice in the Willamette Valley of western Oregon. Depending upon previous crop and soil type, current N fertilizer recommendations for wheat in the Willamette Valley vary widely. Excessive fertilizer poses environmental risk, whereas lower N inputs than required by the crop represent economic losses to growers. Growers and their advisors face the challenge to minimize the environmental risk, and at the same time to maintain or increase economic returns. Questions are often raised concerning the efficient use of N fertilizer and accurately predicting the amount of N needed by wheat following different crops. The first study measured growth, N uptake and N use efficiency (NUE) of winter wheat grown after either a legume or oat for three years. In all three growing seasons, winter wheat showed higher biomass, N uptake and NUE when grown after a legume than after oat. The contribution of legume was evident before the wheat was fertilized in spring, indicating that legume N had mineralized in fall or winter. Contribution of soil N to wheat suggested that fertilizer N can be reduced by 44 kg N ha−1 if a legume is grown previously. Nitrogen use efficiency estimated 50 to 70 days after N application by isotopic method (24 to 94%) was comparable with that estimated simply by difference (21 to 94%) at the same time. The second study predicted gross mineralization rates using analytical models. Comparable N mineralization was predicted by a model assuming remineralization and a model assuming no remineralization, suggesting that remineralization was negligible. In the spring, mineralization-immobilization turnover was at a lower pace than expected in both rotations. In two growing seasons, gross mineralization rates were higher where the previous crop was legume (0.37 to 0.74 kg−1 ha−1 day−1) as compared to where oat was grown previously (0.14 to 0.6 kg−1 ha−1 day). Negative net mineralization indicated that fertilizer N was immobilized in the oat-wheat rotation. The third study evaluated calibration and digestion techniques used to determine elemental concentration in grasses. Use of a dry ashed standard to calibrate the ICP spectrometer generated highly variable calibration curves and was not a viable calibration method. Good agreement was found between chemical and microwave digested standards. Dry ashing resulted in considerable S and Mn losses, whereas, perchloric acid digestion and microwave digestion showed similar results. Our study suggests that if routine analysis are to be performed for macro nutrients or involve trace level work, the best method is microwave digestion with chemical standard calibration of ICP spectrometer.
