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.

Book excerpt: Soybean is one of the organisms largely contributing to our life. Therefore, it is important to know soybean from various aspects. The knowledge and soybean itself will be greatly useful, if they are soundly used. The chapters constituting this book present reviews and researches especially concerning the basis of yield, biomass, and productivity in soybean. Yield, biomass, and productivity in plants are some of the bases for maintaining or improving our ecosystem which includes our life and surrounding environments. Therefore, this book is expected to be useful for many people. Of course, more researches and investigations are important to further gain the knowledge concerning the basis of yield, biomass, and productivity and make them useful for our ecosystem.

Download or read book Effect of Relative Maturity on Soybean Yield and Cover Crop Biomass Evaluation Methods written by Wayde Looker and published by . This book was released on 2019 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ohio contains many acres of continuous soybean [Glycine max (L.) Merr.] production that may benefit from the incorporation of a fall-planted cover crop. Timely planting is extremely important when establishing a fall-planted cover crop. To ensure that cover crops are planted in a timely manner, soybean varieties with an earlier relative maturity may be planted so that soybeans are harvested earlier in the fall allowing for more timely cover crop planting. However, soybean relative maturity also impacts soybean grain yield, with earlier maturing varieties yielding less compared to later maturing varieties. The objectives of this study were to evaluate the relationship between relative maturity and grain yield, plant height, seed protein content, seed oil content and number of days to anthesis and physiological maturity. This study was completed during 2017 and 2018 at the Northwest Agricultural Research Station (NWARS) in Custar, Ohio, and the Western Agricultural Research Station (WARS) in South Charleston, Ohio. Grain yield, plant height, maturity date, and grain protein and oil concentration were measured. All measurements were taken just prior to or at harvest when grain was near 13% moisture content. Soybean yields plateaued at a 2.9 maturity at NWARS and 3.2 maturity at WARS. It was also determined that the earliest maturities reached the R8 growth stage approximately one month before the latest maturities (29.9 days at NWARS and 36.5 days at WARS) while the difference was about 10 days for R1 (8.7 days at NWARS and 12 days at WARS). Plant height held a linear relationship to relative maturity and increased as relative maturity increased. Seed protein content and seed oil content also held a linear relationship to relative maturity. Biomass accumulation is a useful way to measure the amount of vegetative growth produced by a cereal rye and oat cover crop. However, biomass measurements can be slow and labor intensive and a faster method may be available to estimate the accumulated biomass. The objective of this study was to evaluate the relationship between normalized difference vegetation index (NDVI), fractional green canopy cover (FGCC), and biomass of a cereal rye and oat cover crop. This study was conducted in 2017 and 2018 at WARS and NWARS using a split plot randomized complete block design with four replications of treatments. The main plot factor was four cover crop planting dates (late September to late October) and the sub-plot factor was two cover crop termination dates (late April and early May). Normalized difference vegetation index measurements, FGCC measurements, and biomass samples were collected in the fall and spring at each location. The results showed a quadratic relationship between both NDVI and FGCC to the biomass of the cereal rye and oat cover crop. However, the adjusted R2 value and the RMSE of the FGCC was greater, suggesting that the FGCC was a better indicator of biomass compared to NDVI.

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 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Planting date plays a significant role in determining soybean growth, development and seed yield. The objectives of this experiment were to evaluate the effects of late planting date, management system, and maturity group on the growth, development and seed yield of maturity group VII and VIII soybean under dry land conditions in the Southeastern coastal plain of the United States. Plant growth and development, seed yield, yield components, and seed oil and protein concentrations were evaluated throughout the season. These experiments were conducted in South Carolina at the Edisto Research and Education Center near Blackville and the Pee Dee Research and Education Center near Florence. Soybean was planted at four weekly intervals starting on 15-June in both 2011 and 2012. Pioneer 97M50 (a MG VII determinate variety) and Prichard Roundup Ready (a MG VIII determinate variety) were selected based on their adaptation to the Southeast. The two management systems were: a strip-till (ST) system using a John Deere MaxEmerge Vaccum planter + Unverferth 300 strip till with 96-cm row spacing and a drilled no-till (NT) planting system with 19-cm row spacing. Plant growth was evaluated based on leaf area index (LAI), Normalized Difference Vegetation Index (NDVI), and plant height (HT). Plant development was calculated based on the duration (days) of growth stages. Growth stages were recorded weekly from 10 randomly selected plants in each plot. The beginning of each stage was determined when at least 50% of plants were at that stage. Overall, planting after 22 June appeared to reduce seed yield. The ST system increased the seed yield compared to the drilled NT system. Yields were greater for the MG VIII variety than the MG VII variety. LAI, NDVI, and HT at R2 and R4 were generally reduced with delayed planting dates. Later planting shortened the duration of both vegetative and reproductive growth stages for both MG VII and VIII soybeans. Shortened duration of vegetative growth and seed filling period might have contributed most to the lower yields observed in delayed planting dates. Planting date did not affect either protein or oil concentration. Protein concentration in the seed was found to be significantly higher and oil concentration lower in soybean grown in the ST system than in the drilled NT system. Positive correlations were found between: seed yield and LAI, NDVI, and HT at R2 and R4; seed yield and duration of vegetative and seed filling growth period; and seed yield and dry weight of each plant part (branches, stems, petioles, leaves, and pods).

This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.
