The states of Pohnpei and Yap in the Federated States of Micronesia currently produce limited amount of food locally. Exporting food is also limited therefore importing substantial quantities of vegetables, fruits and root crops amounts to millions of dollars annually. This is partly owing to a lack of necessary information on crop production locally to assist producers in their production. To help contribute to rectifying this situation, this manual is aimed to provide guidelines for farmers and producers on seedling production and management, plant spacing, cropping program, soil fertility and crop protection.
Comparison is a powerful cognitive research tool in science since it does "across studies" to evaluate similarities and differences, e.g. across taxa or diseases. This book deals with comparative research on plant disease epidemics. Comparisons are done in specifically designed experiments or with posterior analyses. From the apparently unlimited diversity of epidemics of hundreds of diseases, comparative epidemiology may eventually extract a number of basic types. These findings are very important to crop protection. Plant disease epidemiology, being the ecological branch of plant pathology, may also be of value to ecologists, but also epidemiologists in the areas of animal or human diseases may find interesting results, applicable to their areas of research.
