Book Description
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 dissemination 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 con cerned if the printing and distribution of the volume 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 Cor poration 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 26 (thesis year 1981) a total of 11 ,048 theses titles from 24 Canadian and 21 8 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 26 reports theses submitted in 1981, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Description
Increases in soybean productivity have been relatively small compared to other major economic crops. Wet-soil culture, a relatively new technique of growing soybeans under a high controlled water table, has increased soybean production potential under Australian conditions. Therefore, two field experiments during 1985 and 1986 seasons were conducted with U.S. adapted varieties at the Plant Science Research Center, Mississippi State University. The first study had twenty-four varieties from three different maturity groups tested in three soil moisture regimes: wet-soil culture + N, conventional irrigation and dry. The 1985 season showed low performance of soybean plants grown in wet-soil culture compared to conventional irrigation and dry grown beans. Thiswas due to the water table being higher than intended, which resulted in near flooding. Planting of flat beds contributed to this near flooding situation. By planting on elevated beds in 1986, the wet-soil culture outyielded the other two soil moisture regimes due to better water table control. The second study was a combination of two varieties, five rates of N and two times of initiating wet-soil culture. The varieties were Tracy-M and Centennial (Leflore in 1986). Nitrogen was surface applied as urea at five rates. Time of initiating wet-soil culture was V3 and V8 growth stages. The same problem of near flooding occurred in this experiment, as evidenced by stem splitting. This morphological change was not present in 1986. Seed yield was slightly (...).

Book Description
This book compiles information relevant to understanding soybean production processes and condenses it into a single volume. The authors identify production practices and bring together diverse information that suggests ways for producers to better utilize the soil and climatic resources of the midsouthern U.S. to enhance production of this valuable and versatile crop. This publication makes a special effort to focus on information that will enhance soybean production in the midsouth, where yields have been lower than those in the upper midwester n portion of the U.S., however, much of the information, such as statistics and crop models, will be applicable to other regions, from Texas to the Carolinas.

Book Description
Bringing together a wealth of knowledge, Environmental Management Handbook, Second Edition, gives a comprehensive overview of environmental problems, their sources, their assessment, and their solutions. Through in-depth entries and a topical table of contents, readers will quickly find answers to questions about environmental problems and their corresponding management issues. This six-volume set is a reimagining of the award-winning Encyclopedia of Environmental Management, published in 2013, and features insights from more than 400 contributors, all experts in their field. The experience, evidence, methods, and models used in studying environmental management are presented here in six stand-alone volumes, arranged along the major environmental systems. Features The first handbook that demonstrates the key processes and provisions for enhancing environmental management Addresses new and cutting-edge topics on ecosystem services, resilience, sustainability, food–energy–water nexus, socio-ecological systems, and more Provides an excellent basic knowledge on environmental systems, explains how these systems function, and offers strategies on how to best manage them Includes the most important problems and solutions facing environmental management today In this fourth volume, Managing Water Resources and Hydrological Systems, the reader is introduced to the general concepts and processes of the hydrosphere with its water resources and hydrological systems. This volume serves as an excellent resource for finding basic knowledge on the hydrosphere systems and includes important problems and solutions that environmental managers face today. This book practically demonstrates the key processes, methods, and models used in studying environmental management.

Book Description
In the context of improving water productivity, there is a growing interest in deficit irrigation, an irrigation practice whereby water supply is reduced below maximum levels and mild stress is allowed with minimal effects on yield. Under conditions of scarce water supply and drought, deficit irrigation can lead to greater economic gains than maximizing yields per unit of water for a given crop; farmers are more inclined to use water more efficiently, and more water-efficient cash crop selection helps optimize returns. However, this approach requires precise knowledge of crop response to water as drought tolerance varies considerably by species, cultivar and stage of growth. The studies present the latest research concepts and involve various practices for deficit irrigation. Both annual and perennial crops were exposed to different levels of water stress, either during a particular growth phase, throughout the whole growing season or in a combination of growth stages. The overall finding, based on the synthesis of the different contributions, is that deficit or regulated-deficit irrigation can be beneficial where appropriately applied. Substantial savings of water can be achieved with little impact on the quality and quantity of the harvested yield. However, to be successful, an intimate knowledge of crop behavior is required, as crop response to water stress varies considerably.

Book Description
The soybean is a crop of global importance and is one of most frequently cultivated crops worldwide. It is rich in oil and protein, used for human and animal consumption as well as for industrial purposes. Soybean plants also play an important role in crop diversification and benefit the growth of other crops, adding nitrogen to the soil during crop rotation. With contributions from eminent researchers from around the world, The Soybean provides a concise coverage of all aspects of this important crop, including genetics and physiology, varietal improvement, production and protection technology, utilization and nutritional value.
