Mycorrhiza
The second edition of Mycorrhiza falls into a time period of excep tionally rapid growth in mycorrhizal research. Therefore the edi tors have been most pleased with the decision of the Springer Verlag to revise the first edition and to incorporate the remarkable advances experienced in the mycorrhizal field. The pace of discovery has been particularly fast at the two poles of biological complexity, the molecular events leading to changes in growth and differentiation, as well as the factors regulating the structure and diversity of natural populations and communities. Therefore the most significant changes introduced in the new edition of this book are found within these topics. Not only wer...
Sending Farmers Back to School
The authors evaluate the impact of farmer field schools, an intensive participatory training program emphasizing integrated pest management. Their evaluation focuses on whether participation in the program has improved yields and reduced pesticide use among graduates and their neighbors who may have gained knowledge from graduates through informal communications. The authors use panel data covering the period 1991-99 in Indonesia. Their analysis, employing a modified "difference-in-differences" model, indicates that the program did not have significant effects on the performance of graduates and their neighbors. The authors discuss several plausible explanations for this outcome and suggest recommendations for improvements.
Seed potato technology
This book provides basic knowledge on how to produce, multiply and use propagation material in seed potato production and supply systems world wide. Healthy, vigorous seed tubers are essential in potato production. Producing them used to be expensive and difficult. Multiplication rates in the field are low, seed-borne diseases are numerous and seed tubers lose quality during storage between growing seasons. Recently, novel methods of multiplication have revolutionised the seed potato industry. This has resulted in a diversity of seed production systems adjusted to the local potential and needs. This book summarises the current knowledge and assesses the efficient use of modern technology in ...

Smaller, flavorful tomatoes are becoming more popular than beefsteak tomatoes, greenhouse-grown tomatoes have entered the marketplace, and home gardeners are using the Internet to obtain information for g
Areawide Pest Management
Pest management has long been a problem for farmers worldwide and new techniques are continually being developed to reduce the adverse effects of pest populations. The use of areawide pest management has increased dramatically over the past decade and offers potential advantages to traditional and more localized approaches. Suppression over a broad area can reduce re-infestation of previously treated areas and the specific pest management techniques may be more effective when applied over larger areas. Providing the first comprehensive discussion of areawide pest management, this book will explore the theoretical development and implementation of techniques from a worldwide perspective. Areas covered include history and development, biological and ecological impacts and recent case studies of pest management programmes.
