The soybean is a crop of global importance and is one of the most frequently cultivated crops worldwide. It is rich in oil and protein and is used for both human and animal consumption as well as for industrial purposes, such as biofuels. Soybean crops also play an important role in crop diversification and benefit other crops due to its addition of nitrogen to the soil during crop rotation. With contributions written by researchers from around the world, "The Soybean" provides a concise coverage of recent research on all aspects of this significant crop. Chapters discuss the history and importance of soybean production in agriculture followed by details of the plant's physiology and developments in breeding and genetics. The diverse cropping systems used in production are highlighted alongside crop management and protection strategies. Technology for processing and utilization, soybean's nutritional value and the outlook for global marketing and trade are also addressed.

This book presents a simple, straightforward discussion of the principles and processes involved in the production of grain yield by agronomic crops, and how these processes underlie and influence management decisions. The focus is on grain crops, principally maize and soybean, although the general principles apply equally well to cereals, grain legumes and oil crops. Management decisions define all cropping systems - what (crop species, variety), where (climate), when (planting date), and how (row spacing and population density) are the fundamental choices. Knowledge of the fundamental processes responsible for plant growth and the accumulation of yield simplifies the decision-making process and leads to improved management decisions, higher grain yields, and cropping systems that are efficient, resilient and sustainable. The contents include: * Basic plant growth processes e.g. photosynthesis, respiration, evapotranspiration * Growth and production of yield * Crop management - seed quality, variety selection, plant date, row spacing * Crop production in the future - climate change, GMOs, precision data and new crops Intended for researchers in crop science, agronomy and plant science, and crop production practitioners, this book will enable readers to make better, more informed management decisions; decisions that will help maintain a well-fed world in the future.

This new edition of an established title examines the determination of grain crop yield from a unique perspective, by concentrating on the influence of the seed itself. As the food supply for an expanding world population is based on grain crops harvested for their seeds, understanding the process of seed growth and its regulation is crucial to our efforts to increase production and meet the needs of that population. Yield of grain crops is determined by their assimilatory processes such as photosynthesis and the biosynthetic processes in the seed, which are partly regulated within the seed itself. Providing a timely update in this field and highlighting the impact of the seed on grain crop yields, this book: * Describes all aspects of seed growth and development, including environmental and genetic effects on growth rate and length of the filling period. * Discusses the role of the seed in determining the two main yield components: individual seed weight and number of seeds per unit area. * Uses the concepts and models that have been developed to understand crop management and yield improvement. Substantially updated with new research and further developments of the practical applications of the concepts explored, this book is essential reading for those concerned with seed science and crop yield, including agronomists, crop physiologists, plant breeders, and extension workers. It is also a valuable source of information for lecturers and graduate students of agronomy and plant physiology.
