Book Description
Commercial nurseries often grow containerized conifer seedlings for extended periods to reach pre-determined size & shoot/root ratio targets in order to enhance field survival. This report describes a study that addresses the consequences of this practice. In the study, investigators grew white spruce, red spruce, and eastern white pine in three hard-wall container types and three mesh-covered soil plug types. Seedlings were grown either for a short period designed to produce sufficient rooting in hard-wall plugs to facilitate extraction & handling, or for an extended growing period designed to produce large seedlings with low shoot/root ratios. The results compare field growth of seedlings from the two rearing regimes and the implications for nursery practice are discussed.

Book Description
Forest regeneration is a cornerstone of managing forests sustainably. Prompt and efficient regeneration gives society the benefits of wood products, as well as the economic wealth that obtaining and processing wood creates. Good reforestation habits provide more wood from less land and increased timber productivity means that demand for wood products can be met with less impact on non-wood uses of the forest. This symposium which was attended by nearly 200 professionals included participants from Canada, the United States, Europe, and Asia had as its focus the issue of forest regeneration which is a cornerstone of managing forests sustainably. Papers presented cover a range of topics related to reforestation within the broader categories of: the status of reforestation and afforestation around the world; nursery methodologies to produce target seedlings; planting and planting site treatments to optimize regeneration; and enhancing timber production and non-timber values through stand establishment.--Document.

Book Description
This publication capitalizes on the experience of scientists from the North Africa and Near East countries, in collaboration with experts from around the world, specialized in the different aspects of greenhouse crop production. It provides a comprehensive description and assessment of the greenhouse production practices in use in Mediterranean climate areas that have helped diversify vegetable production and increase productivity. The publication is also meant to be used as a reference and tool for trainers and growers as well as other actors in the greenhouse vegetables value chain in this region.

Book Description
Tropical Nursery Manual, U.S. Department of Agriculture, Forest Service Agriculture Handbook 732, was first published in 2014.This handbook was written for anyone endeavoring to start and operate a nursery for native and traditional plants in the tropics. Because the tropics cover a vast area of the world, however, the scope of the handbook is geared toward readers in the U.S. affiliated tropics. Specifically, the U.S. affiliated tropics are a diverse area spanning two oceans and half the globe, including the nations of the Federated States of Micronesia, the Republic of Palau, and the Republic of the Marshall Islands, as well as the Territory of Guam, the Commonwealth of the Northern Mariana Islands, the Territory of American Samoa, the Common-wealth of Puerto Rico, the U.S. Virgin Islands, and the State of Hawai'i, southern California, Texas, and the southern part of Florida. Areas with similar conditions may also be served.

Book Description
Note for the electronic edition: This draft has been assembled from information prepared by authors from around the world. It has been submitted for editing and production by the USDA Agricultural Research Service Information Staff and should be cited as an electronic draft of a forthcoming publication. Because the 1986 edition is out of print, because we have added much new and updated information, and because the time to publication for so massive a project is still many months away, we are making this draft widely available for comment from industry stakeholders, as well as university research, teaching and extension staff.
