Download or read book Two Studies Evaluating Input Use in Soybean and Cotton Production written by Nathanael Mark Thompson and published by . This book was released on 2012 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Farmers are price takers for both inputs and outputs. Therefore, when the prices of inputs rise, as they have with many inputs used in agricultural production, optimal production practices may change. Two separate studies of the impacts of agricultural technology on input use in crop production were undertaken in this thesis. The first study evaluated economically optimal plant population considering seeding rate, maturity group, row spacing, and input-output prices in soybean production in the rolling uplands region of the upper Midsouthern United States. Data from field experiments at the University of Tennessee Research and Education Center at Milan, Tennessee during 2005, 2006, and 2007 were used to model yield response to plant population density (PPD). Given that farmers must make their planting decisions based on expected weather, original models were weighted by year based on the Angstrom weather index. Evaluation of weighted average response functions found that maturity group IV soybean cultivars planted in 38 cm rows at seeding rates necessary to achieve final PPD of 115,000 plants ha−1 would maximize farmers returns to soybean production. The second study evaluated factors influencing cotton farmers' decisions to adopt information technologies for variable-rate input application and subsequent perceptions of directional changes in the overall use of fertilizer in cotton. Data from the Cotton Incorporated 2009 Southern Precision Farming Survey were evaluated using probit models with sample selection given the sequential nature the adoption decision and farmer perceptions of directional changes in fertilizer use. Results suggest that cotton farmers in the sample who rented more of their cotton area and used picker harvest technology were more likely to perceive that overall fertilizer use declined with the use of the selected information technologies and VRT. This and other key findings of this research have implications for a wide range of audiences ranging from University Extension to policy makers given the economic and environmental impacts.

Download or read book Crop Stress Management and Global Climate Change written by José Luis Araus and published by CABI. This book was released on 2011 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture has shaped our planet into the world we know, but its continued success is threatened by changing weather patterns. Climate change is a diverse, multifactorial phenomenon and the agronomic strategies we employ to combat its effects need to be case-specific, with significant regional differences. With two major sections, the first explaining the challenges posed by climate change and the second reviewing the current research avenues employed, this book combines detailed discussion of physiological plant responses with practical experience on crop stress management and breeding. Using a number of illustrative case studies, it discusses how the stresses resulting from climate change could be overcome by assessing, measuring and predicting environmental changes and stresses, and identifying opportunities for adapting to multifactorial change. A global effort to combine climate change science with policy is desperately needed. Climate change will continue to pose many challenges to agriculture in the future but by taking an integrative approach to predicting and adapting to change, this book will inspire researchers to turn those challenges into opportunities.

Download or read book Agricultural Productivity and Producer Behavior written by Wolfram Schlenker and published by University of Chicago Press. This book was released on 2019-11-13 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural yields have increased steadily in the last half century, particularly since the Green Revolution. At the same time, inflation-adjusted agricultural commodity prices have been trending downward as increases in supply outpace the growth of demand. Recent severe weather events, biofuel mandates, and a switch toward a more meat-heavy diet in emerging economies have nevertheless boosted commodity prices. Whether this is a temporary jump or the beginning of a longer-term trend is an open question. Agricultural Productivity and Producer Behavior examines the factors contributing to the remarkably steady increase in global yields and assesses whether yield growth can continue. This research also considers whether agricultural productivity growth has been, and will be, associated with significant environmental externalities. Among the topics studied are genetically modified crops; changing climatic factors; farm production responses to government regulations including crop insurance, transport subsidies, and electricity subsidies for groundwater extraction; and the role of specific farm practices such as crop diversification, disease management, and water-saving methods. This research provides new evidence that technological as well as policy choices influence agricultural productivity.

Download or read book A Comprehensive Survey of International Soybean Research Genetics Physiology Agronomy and Nitrogen Relationships written by James E. Board and published by . This book was released on 2013 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean is the most important oilseed and livestock feed crop in the world. These dual uses are attributed to the crop's high protein content (nearly 40% of seed weight) and oil content (approximately 20%); characteristics that are not rivaled by any other agronomic crop. Across the 10-year period from 2001 to 2010, world soybean production increased from 168 to 258 million metric tons (54% increase). Against the backdrop of soybean's striking ascendancy is increased research interest in the crop throughout the world. Information in this book presents a comprehensive view of research efforts in genetics, plant physiology, agronomy, agricultural economics, and nitrogen relationships that will benefit soybean stakeholders and scientists throughout the world. We hope you enjoy the book.

Download or read book Planting Date and Maturity Group Selection to Maximize Soybean Yield and Subsequent Dry Matter and Nutrient Uptake Partitioning and Removal written by Adam Paul Gaspar and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: As soybeans have become a major U.S. crop and key component in different cropping systems over the past half century, advancements in breeding and production practices have shown gains in yield and economic profitability for producers. Important production considerations included soil fertility, proper maturity group (MG) selection, and planting date. In southern Wisconsin, maximum yields are reduced by 21.2 kg ha-1 day-1 after May 10th (Gaspar and Conley, 2015). Growers have realized this effect and gradually shifted their soybean planting earlier. However, some believe that while producers are planting earlier and experiencing a longer growing season, they have not adequately adjusted their soybean MG's. Coincident with earlier planting dates is the increased risk of sub-optimal stands and the need for replanting some years. Proper replanting methods (fill-in) and optimal final plant stands (>247,000 plants ha-1) have been determined by Gaspar and Conley (2015) but again, the proper MG to use in replant or essentially late planting scenarios to maximize yield and avoid fall frost damage is unclear. This document provides data demonstrating the importance of MG selection and the negative impact of delayed planting in the Northern Corn Belt. Economically and environmentally sustainable soil fertility programs are a necessity for modern soybean production systems. Unfortunately, soybean nutrient uptake and partitioning models are primarily built from work conducted in the early 1960's with obsolete soybean genetics and production practices (Hanway and Weber, 1971a; Hanway and Weber, 1971b). Since the 1960's, yields have nearly doubled to 2906 kg ha-1 in 2013 (USDA-NASS, 2014b) and soybean physiology has been altered with approximately one additional week of reproductive growth (Rowntree et al., 2014) and greater harvest index's (HI) (Kumudini et al., 2001) for currently cultivated varieties. More precise and accurate estimates have the potential to increase grower profitability by applying only what the crop needs while possibly decreasing the environmental impact in terms of nutrient loads in the Mississippi watershed, which accounts for more than 90% of all US soybean acres (USDA-ERS, 2014). This document highlights large changes in nutrient uptake, partitioning, and removal of current soybean genetics and production practices.

Download or read book Increasing Soybean Yields Through Management and the Role for Nitrogen Fixation written by Janelle Donahue and published by . This book was released on 2012 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high yield soybean experiment was conducted to compare the management intensive practices of recent soybean record holder, Kip Cullers, to conventional production practices in 2008 to 2010. Preplant fertilizer applications of poultry litter and mineral fertilizers were compared for their effects on soybean yield and nodulation. While soybean yields increased between 2008 and 2010, preplant treatment differences were inconsistent. Soybean nodule weight, numbers, and size decreased over the three year experiment, but differences between poultry litter and mineral fertilizer applications did not occur. Foliar fertilizers, micronutrient, and irrigation applications were also studied, but did not have significant effects on soybean yield in this experiment. Overall, differences were not observed the high input treatments and conventional practices. To assess if changes have occurred in soybean nodulation capabilities and tolerance to mineral N over time, greenhouse and field experiments were conducted in 2010 and 2011 to survey soybean cultivars released from 1930 to 2002. Results from the field study demonstrate increased soybean yields with increasing cultivar release date, but similar trends in soybean nodulation, total N and leaf ureide concentrations were not observed. These experiments do not support a novel tolerance for N inhibition or loss of nodulation capabilities over time.

Download or read book World Development Report 2020 written by World Bank and published by World Bank Publications. This book was released on 2019-11-19 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global value chains (GVCs) powered the surge of international trade after 1990 and now account for almost half of all trade. This shift enabled an unprecedented economic convergence: poor countries grew rapidly and began to catch up with richer countries. Since the 2008 global financial crisis, however, the growth of trade has been sluggish and the expansion of GVCs has stalled. Meanwhile, serious threats have emerged to the model of trade-led growth. New technologies could draw production closer to the consumer and reduce the demand for labor. And trade conflicts among large countries could lead to a retrenchment or a segmentation of GVCs. World Development Report 2020: Trading for Development in the Age of Global Value Chains examines whether there is still a path to development through GVCs and trade. It concludes that technological change is, at this stage, more a boon than a curse. GVCs can continue to boost growth, create better jobs, and reduce poverty provided that developing countries implement deeper reforms to promote GVC participation; industrial countries pursue open, predictable policies; and all countries revive multilateral cooperation.

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.
