This book was released on 2020 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean [Glycine max (L.) Merr.] biomass and yield has increased over the past several decades in the midsouthern United States; therefore, a better understanding of the nutrient requirements of the crop is needed. Nutrient uptake and partitioning in soybean is fundamental to understanding the physiology of nutrient accumulation relative to crop yield. Technological advances and improved management strategies in soybean production have contributed to significant yield increases. Research was established in 2017 and 2018 in Stoneville, MS, to evaluate soybean nutrient uptake and partitioning across multiple soybean cultivars and two planting dates. Coarse- and fine-textured soils commonly cropped in Mississippi under furrow irrigation were utilized. Soybean total aboveground biomass was collected at multiple growth stages, including V4, R2, R5.5, R6.5, and R8. At reproductive stages R5.5 to R8, soybean aboveground biomass was partitioned into senesced leaves, pods, and seeds. All biomass components were analyzed for content of primary macronutrients. Two soybean cultivars for each of four herbicide-resistant technologies were selected to represent subplot treatments. The greatest yield was produced by dicamba- and glyphosate-tolerant HT, followed by glufosinate tolerant, followed by conventional HT. Soybean planted in April produced grain yield greater than May planted soybean. Averaged across four site years, field removal of total N, P2O5, and K2O partitioned into the seed at physiological maturity was approximately 175 kg N ha-1, 33 kg P2O5 ha-1, and 120 kg K2O ha-1.

Download or read book Agroecosystems Facing Global Climate Change The Search for Sustainability written by José M. Mirás-Avalos and published by Frontiers Media SA. This book was released on 2019-02-05 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global change is posing new threats to agroecosystems. First, climate modifications in the spatial and temporal distribution of rainfall increase the risks of severe droughts during the growing season of most crops. Second, conventional agriculture has led to the extension of mono-crop fields that decreased biodiversity in agroecosystems; it is possible that these fields will lack resilience when faced with changing climate. In addition, a new conscience has arisen and consumers tend to look for healthy products that, sometimes, do not match the objectives of conventional agriculture. In this context, sustainable and environmentally friendly agricultural practices that can cope with the new global change scenario are needed. This eBook compiles state-of-the-art research on the agroecosystems response to global change and on how to manage these new scenarios. Despite the broad scope of the topic, this Research Topic covers a wide range of subjects, including biodiversity, crop performance, novel agricultural practices and soil properties.

Download or read book Phosphorus Management in Crop Production written by Nand Kumar Fageria and published by CRC Press. This book was released on 2017-02-17 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world population is projected to reach nine billion by 2050, and in the coming years, global food demand is expected to increase by 50% or more. Higher crop productivity gains in the future will have to be achieved in developing countries through better natural resources management and crop improvement. After nitrogen, phosphorus (P) has more widespread influence on both natural and agricultural ecosystems than any other essential plant element. It has been estimated that 5.7 billion hectares of land worldwide contain insufficient amounts of available P for sustainable crop production, and P deficiency in crop plants is a widespread problem in various parts of the world. However, it has been estimated that worldwide minable P could last less than 40 years. For sustaining future food supplies, it is vital to enhance plant P use efficiency. To bring the latest knowledge and research advances in efficient management of P for economically viable and environmentally beneficial crop production in sustainable agriculture, Phosphorus Management in Crop Production contains chapters covering functions and diagnostic techniques for P requirements in crop plants, P use efficiency and interactions with other nutrients in crop plants, management of P for optimal crop production and environmental quality, and basic principles and methodology regarding P nutrition in crop plants. The majority of research data included are derived from many years of field, greenhouse, and lab work, hence the information is practical in nature and will have a significant impact on efficient management of P-fertilizers to enhance P use efficiency, improve crop production, promote sustainable agriculture, and reduce P losses through eluviations, leaching, and erosion to minimize environmental degradation. A comprehensive book that combines practical and applied information, Phosphorus Management in Crop Production is an excellent reference for students, professors, agricultural research scientists, food scientists, agricultural extension specialists, private consultants, fertilizer companies, and government agencies that deal with agricultural and environmental issues.

Download or read book Effect of High Temperature on Crop Productivity and Metabolism of Macro Molecules written by Amitav Bhattacharya and published by Academic Press. This book was released on 2019-06-14 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effect of High Temperature on Crop Productivity and Metabolism of Macro Molecules presents a comprehensive overview on the direct effect of temperatures defined as "high", a definition which increasingly includes a great number of geographic regions. As temperature impacts the number of base growth days, it is necessary to adapt plant selection, strategize planting times, and understand the expected impact of adaptive steps to ensure maximum plant health and crop yield. Global warming, climate change and change in environmental conditions have become common phrases in nearly every scientific seminar, symposium and meeting, thus these changes in climatic patterns constrain normal growth and reproduction cycles. This book reviews the effect of high temperature on agricultural crop production and the effect of high temperature stress on the metabolic aspects of macro molecules, including carbohydrates, proteins, fats, secondary metabolites, and plant growth hormones. Focuses on the effects of high temperature on agriculture and the metabolism of important macro-molecules Discusses strategies for improving heat tolerance, thus educating plant and molecular breeders in their attempts to improve efficiencies and crop production Provides information that can be applied today and in future research
Download or read book Nutrient Use Efficiency in Plants written by Malcolm J. Hawkesford and published by Springer. This book was released on 2014-11-14 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutrient Use Efficiency in Plants: Concepts and Approaches is the ninth volume in the Plant Ecophysiology series. It presents a broad overview of topics related to improvement of nutrient use efficiency of crops. Nutrient use efficiency (NUE) is a measure of how well plants use the available mineral nutrients. It can be defined as yield (biomass) per unit input (fertilizer, nutrient content). NUE is a complex trait: it depends on the ability to take up the nutrients from the soil, but also on transport, storage, mobilization, usage within the plant, and even on the environment. NUE is of particular interest as a major target for crop improvement. Improvement of NUE is an essential pre-requisite for expansion of crop production into marginal lands with low nutrient availability but also a way to reduce use of inorganic fertilizer.
