Managing Your Market Response

Nursery Crops
A brief report for nurseries which offers ideas on how to overcome some of the recent challenges in the nursery industry. To facilitate that effort, Oregon State University tracked nursery sales and pricing in order to offer a fresh look at what drives sales and how the industry can respond to recent changes.

A Survey of Vaccinium Cultural Practices in Australia Emphasizing Implications for Mycorrhizal Infection

A report based on a survey conducted in Australia of 171 blueberry growers in four Australian states to collect detailed information on cultural practices that have been shown to effect the infection of commercial plantings with ericoid mycorrhizal fungi (EMF).

Differences in Growth, and Nitrogen Uptake and Storage Between Two Container-Grown Cultivars of Rhododendron

The information provided by this study will aid in the development of fertilizer management strategies for container nursery production practices that will decrease fertilizer use and production costs, improve plant quality, while minimizing N losses to the environment.

Ten-Year Growth and Survival of Douglas-fir Seedlings Treated with Plant Growth Regulating Substances at Transplant

Nursery Crops
A report on how the application of specific plant growth regulators (PGRs) and a moisture retention gel to the root systems of Douglas-fir can influence root indole-3-acetic acid (IAA) content, and tree growth and survival 10 years after planting in a clearcut.

Ebb and Flow From an Engineer's Viewpoint

Agricultural engineering specialist affiliated with the University of Connecticut discusses the benefits of using an ebb and flow irrigation system in a greenhouse environment. Examples of crops successfully grown using the ebb and flow system are provided.

Capillary Beds

Nursery Crops
A discussion about capillary beds and also a how to guide on the construction of the beds for nursery production. Topics addressed include the construction of capillary beds, costs (labor, equipment, materials), root growth and development, leaf scorch, and pathogens.

New Pesticide Rules to Protect Ground Water Adopted by Washington State Department of Agriculture

An overview of the pesticide rules adopted by the Washington State Department of Agriculture in 1989. The new rules restricted pesticides containing one of more of the 18 active ingredients identified as having potential to contaminate ground water.

Application of Ectomycorrhizal Fungi in Vegetative Propagation of Conifers

Plant Propagation
A report on the potential use of ectomycorrhizal fungi in vegetative conifer production to increase adventitious shoots and enhance root formation and/or subsequent root branching. The authors specifically discuss in vivo cutting production, in vitro organogenesis and somatic embryogenesis.

Plant Pathogens - Plant Diagnosis Clinic

Plant Disease
An overview of the B.C. Ministry of Agriculture and Fisheries plant diagnosis clinic at Cloverdale. The author discusses the history of the clinic, types of specimens examined, identified diseases and associated crops, and grower losses due to disease.

Container Spacing Strategies Modify Media Temperature and Plant Growth

Nursery Crops
Research was conducted to determine container spacing strategies to reduce the effects of media temperature increases. The study was completed at a nursery in Florida using Ilex crenata `Helleri'. The authors discuss the results and offer incites into potential spacing strategies.
