Successful vegetable production in a modern competitive market requires an understanding of many more factors than the biology of crops and the production techniques involved. This major new textbook brings the science and practice of vegetable production right up to date by addressing modern culture techniques and the recent challenges of consumer demand facing producers today. It introduces vegetable production from the perspective of producing high quality produce that satisfies the needs of the modern consumer. Beginning with the basics of how vegetables are grown using high and low input methods, including organic and sustainable production techniques, the book goes on to introduce and discuss many topics covered less comprehensively in older texts, including Good Agricultural Practices to improve quality, reduce biological contamination and secure food safety; water management; cropping systems; plasticulture; protected culture and mineral nutrition. Vegetable Production and Practices also introduces the use of molecular biology for genetic improvement of crops. Issues specific to individual vegetable crops are addressed by family, including their diseases, harvesting, quality attributes and other issues of increasing importance to consumers, including the role of vegetables in human health. Professor Gregory E. Welbaum has a long history of teaching successful courses in horticulture at Virginia Tech and other universities in the US and worldwide. Vegetable Production Practices has been specifically designed to accompany courses in vegetable crop production, so is ideally suited to inspire students in crop and horticultural sciences, as well as provide a useful reference for experienced practitioners.

"Greenhouse IPM with an Emphasis on Biocontrols is designed to help greenhouse growers, crop consultants, and IPM scouts develop biological control (biocontrol) and integrated pest management (IPM) systems that will maximize yields while reducing pesticide usage in greenhouses. It begins with an introduction to IPM and its principles, information on starting an IPM/biocontrol program and using compatible pesticides, and then addresses many of the most common greenhouse pests and their biocontrols. This comprehensive guide also includes a glossary, resource list, appendixes, and more than 90 full-color photographs. Learn how to develop biological control (biocontrol) and integrated pest management (IPM) systems that will maximize yields while reducing pesticide usage in greenhouses; IPM and its principles; information on starting an IPM/biocontrol program and using compatible pesticides; and common greenhouse pests and their biocontrols."--PennState Extension website.

This bulletin, based on contributions from various contributors and edited by Dr. D.W. Roubik, introduces the reader to various aspects of natural and insect pollination. It discusses the pollinators themselves, and the ecological and economic importance of pollination, as well as applied pollination in temperate, tropical oceanic islands and mainland tropics, and alternatives to artificial pollinator populations. Prospects for the future are also discussed. Chapter 2 deals with successful pollination with pollinator populations, the evaluation of pollinators and floral biology and research techniques. The behaviour of pollinators and plant phenology and various case studies on the preparation of pollinators for use in tropical agriculture are also discussed. A glossary and various appendices regarding cultivated and semi-cultivated plants in the tropics, pollination contracts and levels of safety of pesticides for bees and other pollinators are included.

"Amber is a semi-precious gem that is formed over eons by natural forces out of the resin of trees. Human fascination with amber dates back to prehistoric times, when it was probably considered to have magical powers and was used for adornment and trade. Amber amulets and beads dating from 35,000 to 1,800 B.C. have been found, and where they have been found (for example in graves hundreds of miles from their chemically determined origins) has often helped to establish ancient trade routes." "The preservative qualities of plant resins were well known by the ancients. The Egyptians used resins to embalm their dead, and the Greeks used them to preserve their wine. Amber often preserved fossils, frequently in a pristine state, of all kinds of animal and plant organisms that made contact with the sticky substance and became trapped in it. These fossils include such fragile organisms as nematodes and mushrooms that ordinarily are not preserved under normal processes of fossilization, as well as larger organisms like scorpions and lizards, and the fossils are preserved in their full three-dimensional form, complete with minute details of scales, mouth parts, antennae, and hairs. It has even been suggested that viable DNA may persist in some amber-trapped organisms." "This book is a compendium of all that we know about life found in amber. It surveys all life forms, from microbes to vertebrates and plants, that have been reported from amber deposits throughout the world, beginning with the earliest pieces dating from some 300 million years ago. It also describes the formation of amber and the location, geological history, and early exploration of the major world amber deposits, including those still being worked today." "The book also provides practical information on how to determine fake amber containing present-day forms of life. It can serve as a beginning for tracing the geological history of a particular group of animals or plants or even reconstructing ancient paleoenvironments, and because amber fossils are preserved so completely, in a transparent medium, they can be intimately compared with related living species. Finally, the book discusses what amber fossils can tell us about evolution and speciation, cellular preservation, and paleosymbiosis." "The book is illustrated with 37 color photographs, 154 black-and-white photographs and drawings, and 8 maps."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
