Application Of Spatial Modeling Tools To Predict Native Bee Abundance In Maine's Lowbush Blueberries, Shannon J. Chapin
Application Of Spatial Modeling Tools To Predict Native Bee Abundance In Maine's Lowbush Blueberries, Shannon J. Chapin
Electronic Theses and Dissertations
Non-native honeybees historically have been used to pollinate many crops throughout the United States, however, recent population declines have revealed the need for a more sustainable pollination plan. Native bees are a natural resource that can play an important role in pollination. I used spatial modeling tools to evaluate relationships between landscape factors and native bee abundance, with a focus on the wild native bees that pollinate Maine’s lowbush blueberries. I applied the InVEST Crop Pollination ecosystem spatial modeling tool, which predicts pollinator abundance based on available floral resources and nesting habitat, to the Downeast Maine region. The InVEST model …

Tb203: Recent Advances In The Biology And Genetics Of Lowbush Blueberry, Daniel J. Bell, Lisa J. Rowland, John Smagula, Frank Drummond
Technical Bulletins
For lowbush blueberries, this publication presents an in-depth look at the biology and genetics of lowbush blueberry. The authors provide details on its genetic composition and the outline the usefulness of various biochemical, genomic, and other markers in studying the plants genetic structure. The authors also provide an overview of the plant’s economic value to Maine, nutritional value, and its life history.

B852: Organic Wild Blueberry Production, Frank Drummond, John Smagula, Seanna Annis, David Yarborough
Bulletins
Recent research carried out under the auspices of a USDA organic transition grant resulted in a better understanding of the interaction of wild blueberry production tactics such as pruning method, soil pH reduction by sulfur (S) application, and organic fertilizer rates on wild blueberry growth, development, and yield. This bulletin is the product of what we have learned over the past four years of this research project.

Mp759: Grower Survey Of Organic Pest Management Practices For Wild Blueberries In Maine With Case Studies, Andrew C. Files, David Yarborough, Frank Drummond
Miscellaneous Publications
This report describes the results of a survey of all known organic blueberry growers in Maine conducted in December 2006. The survey included questions ranging from acreage owned and/or managed to market outlets to pruning techniques to education level of grower to methods of learning new information and was part of a larger, interdisciplinary project addressing organic pest-management strategies for lowbush blueberries.

Tb198: Economic Analysis Of Organic Pest Management Strategies For Lowbush Blueberries Using Enterprise Budgeting, Andrew C. Files, David Yarborough, Frank Drummond
Technical Bulletins
Enterprise budgets were developed for the 12 different pest management treatments of a large-plot organic blueberry transitions project in Maine, covering two prune/harvest cycles (2004–2005 and 2006–2007). Regression analysis of the plot-level yield results for the aggregate of the two prune/harvest cycles indicated that burning fields as compared to mowing fields significantly increased blueberry yields over the aggregate of two prune/harvest cycles. Similarly, adding 1,000 lbs of sulfur before the first prune/harvest cycle significantly increased blueberry yields over the aggregate of two prune/harvest cycles as compared to no addition of sulfur. The addition of fertilizer had no significant impact on …
Variation In The Severity Of Mummy Berry Disease Among Lowbush Blueberry Clones, Laura Penman
Variation In The Severity Of Mummy Berry Disease Among Lowbush Blueberry Clones, Laura Penman
Electronic Theses and Dissertations
Lowbush blueberry production is important for the economy of Maine and the Maritime provinces, and mummy berry disease, caused by Monilinia vaccinii- corymbosi, often reduces plant stand vigor and fruit production. The severity of mummy berry disease among clones of lowbush blueberry were measured in four fields over a two year period (2001 and 2002). In each of 37 clones,lO flowering stems with and without symptoms of blight were randomly selected at flowering to represent "diseased" and "healthy" stem populations, respectively. The severity of leaf and flower blight and fruit mummification was measured for each of these stems, and the …

Miscellaneous Reports
A discussion of two studies of different methods of propagating lowbush blueberry plants. These methods could be used for introducing blueberry plants into existing fields to improve field cover, or to start a blueberry field from scratch.

B780: A Cost Analysis Of Pruning Procedures In Lowbush Blueberry Production, Eric J. Hanson, Amr A. Ismail, Homer Metzger

Burning fields with fuel oil is currently the most practical method of pruning blueberries but is costly and destructive to the organic material on the surface of the soil. Fuel oil is a nonrenewable resource that is rapidly increasing in cost and, in the future, may become less readily available for this use. The need to develop alternative means of pruning lowbush bleuberries is evident. This bulletin compares the economics of six pruning procedures on operations of three sizes. The budgets are based on certain assumptions and costs which will change over time. The results will allow blueberry growers to …
