Relay intercropping soybean into wheat has great potential in Iowa by allowing two harvests on the same land area in the same year. Wheat is planted in September and soybean is interseeded into the standing wheat in May. This system can be important for Iowa by diversifying production, increasing farm productivity, and reducing soil erosion. A three year experiment was conducted near Boone, IA, to determine the effect of soybeans planting dates and spatial arrangements on wheat and soybean in a relay intercropping system, and its relative agronomic efficiency. The experimental design was a split-plot with the main plots (planting dates) arranged in randomized complete blocks with three replications of each treatment. The soybean planting dates were: pre-heading=PD1, heading=PD2, and post-heading=PD3. Five spatial arrangements (sub-plots) were used: 1W:1S (one wheat row alternated with one soybean row), 2W:1S, 2W:2S, 3W:2S, and 4W:3S. Wheat yield was reduced on average by 33% with soybean interplanting, and was proportionally lower than the reduction of wheat plant population during implementation of the skip-row pattern (33 to 50 %). Relay intercropped soybean produced 73 % of the sole crop soybean, indicating skip-row patterns are a good alternative for higher soybean yield. Soybean planting at wheat pre-heading or at heading was the best alternative for this system. Arrangements producing the best soybean yields were not good wheat producers and vice-versa, suggesting that improvements in the yield of one crop will negatively affect the yield of the companion crop in a wheat-soybean relay intercropping system. For soybean oriented producers, 2W:2S, 3W:2S and 4W:3S are good choices due to the high soybean grain yield. Arrangement 1W:1S was intermediate for soybean and wheat yields. A land equivalent ratio (LER) of 1.46, on average, demonstrated the agronomic efficiency of relay intercropping over sole cropping.

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 40 (thesis year 1995) a total of 10,746 thesis titles from 19 Canadian and 144 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 40 reports theses submitted in 1995, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur from the molecular level to the farming system to the global level at time scales ranging from seconds to centuries. For that, scientists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable agriculture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. Because most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world. This book series gathers review articles that analyze current agricultural issues and knowledge, then propose alternative solutions. It will therefore help all scientists, decision-makers, professors, farmers and politicians who wish to build a safe agriculture, energy and food system for future generations.
