Book excerpt: Plants are important for a permanent ecosystem, because in the ecological pyramid plants support all the other living organisms at the base. Very important organization is thought to be the integral process of resource, transport, partitioning, metabolism, and production, which involves yield, biomass, and productivity in plants. Accordingly, it is important to obtain more information about the knowledge concerning yield, biomass, and productivity in plants. Soybean is one of the main crops largely contributing to our life, which is thought to be connected to our ecosystem through the above-mentioned integral process. This book focuses on the soybean, and reviews and research concerning the yield, biomass, and productivity of soybean are presented herein. This text updates the book published in 2017. Although there are many difficulties, the main aim of this book is to present a basis for the above-mentioned integral processes of resource, transport, partitioning, metabolism, and production, which involves yield, biomass, and productivity in plants (soybean), and to understand what supports this basis and the integral process. It is hoped that this and the preceding book will be essential reads.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean (Glycine max L. Merr.) planting date and plant density are agronomic decisions made simultaneously at the beginning of the growing season that can be used to maximize yield and economic return. Research on these basic soybean agronomic decisions must be conducted to support the expansion of soybean production in northern growing regions of the Northern Great Plains (NGP). The objectives of this study were to evaluate the effects of planting dates based on soil temperature on soybean emergence, maturity, and yield for short and long season varieties in Manitoba, and to determine optimum soybean plant density for early to very late planting dates in northern growing regions of the NGP. In the first experiment, calendar date had a greater influence than soil temperature at planting on soybean yield. Soybean yield declined with later planting rather than increasing soil temperature at planting. The earliest planting dates resulted in the greatest soybean yields. In the second experiment, soybean yield-density relationships were responsive to planting date. Yield-density relationships formed early/mid (May 4 to 26) and late/very late (June 2 to 23) planting date groups for combined site years. Early/mid planting dates resulted in greater maximum yields. According to the yield-density model, true yield maximization did not occur for any planting dates and site years within the range of plant densities tested in this field study. Soybean economic optimum seed densities (EOSDs) were much lower than predicted plant densities that maximized yield. Soybean EOSDs were identified as 492,000 and 314,000 seeds ha-1 by marginal cost analysis for early/mid and late/very late planting, respectfully. These values were sensitive to changes in soybean grain price and seed cost. Thus, growers need to adjust EOSDs for changes in price and cost. A combined analysis of soybean yields from both experiments using similar target plant densities determined that a significant negative linear relationship existed between soybean yield and planting date. The greatest soybean yields resulted from early planting and declined by 16 kg ha-1 for each one-day delay in planting from Apr 27 to June 16. However, yield responses varied among site years. The overall recommendation from this study would be to plant soybeans during the month of May at a profit-maximizing seed density, accounting for fluctuating grain price and seed cost.

Available in PDF, EPUB and Kindle. Book excerpt: Soybean Physiology, Agronomy, and Utilization attempts to cover and treat in logical sequence the factors that contribute to the potential and versatility of soybeans. The soybean is a major crop plant in the United States. Based on the utilization of the bean, or products therefrom, a substantial soybean industry has also developed. Its uses, agricultural and industrial, primarily depend on the high content of both protein (ca. 40%) and oil (ca. 20%) in the bean. The book begins by discussing soybean production in the United States and worldwide; the uses and economics of soybean products; and the soybean in physiological research. It explains the growth and development of soybeans. It discusses the physiological processes responsible for assimilating the plant body from the environment, namely photosynthesis, nitrogen fixation, and nitrate reduction. Subsequent chapters examine the impact of environmental variables—such as light, temperature, water, wind, and pests—on soybean plant characteristics as well as soybean breeding, production, processing, and utilization.

This book was released on 2015 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is comprised of two studies on the effects of soybean ( Glycine max (L.) Merr.) planting date (PD) and maturity group (MG) selection on producer expected returns. Having to replant soybean after early-season planting because of poor stand establishment is costly for producers. Replanting costs have increased in the last ten years as seed and other input costs for soybean have increased. Using five years of field trial results from two locations in Arkansas, the yield response to early and late season plant population density has been estimated to determine yield and future revenue potential for the purpose of determining whether or not replanting makes economic sense for a producer. Economically derived soybean replanting thresholds, defined as the number of plants at two or four weeks after planting for the initial planting below which replanting makes economic sense, were established for both locations. Sensitivity analyses on soybean price, seed cost, and producer replanting costs were performed to determine their relative importance on replanting thresholds. Deciding to replant earlier than four weeks after planting was suggested as the yield potential of earlier replanted soybean is higher. The replanting threshold counts, however, also need to be adjusted. In the second study, producer return variance or production risk associated with growing soybean of different maturity and at varying times during the planting season was analyzed. An efficient frontier where returns are maximized at varying levels of risk was calculated for a set of nine locations across six states using three years of data from field experiments. Because a producer can freely select what MG of soybean to plant and when to plant, risk return tradeoffs were studied for planting portfolios featuring soybeans from MG III to VI and PD ranging from as early as the beginning of April in some locations to mid-July. The median level of risk between minimal portfolio risk and the risk level of the return-maximizing MG and PD combination was solved for and expected return and risk was compared between the median-risk portfolio and the profit-maximizing portfolio. This comparison provided insight about the relative cost of risk reduction for the nine different locations. Water consumption, price seasonality, and seed oil and protein concentration were considered in the development of return estimates. Because producer planting risk preferences vary, a spreadsheet tool that can solve for efficient MG and PD planting portfolios is envisioned that will allow the parameters of the optimization to be customizable for the producer.
