Tb107: Effects Of Some Naturally Occurring Chemicals And Extracts Of Non-Host Plants On Feeding By Spruce Budworm Larvae (Choristoneura Fumiferana), M. D. Bentley, D. E. Leonard, S. Leach, E. Reynolds

Technical Bulletins

The authors of this report describe a new laboratory feeding bioassay and its application to the investigation of the effect of a large number of plant extracts and various natural products on feeding by sixth stage spruce budworms.

Tb106: A Transshipment Model Of The Maine Milk Industry, Stuart Mclean, Alan S. Kezis, James Fitzpatrick, Homer B. Metzger

Technical Bulletins

A model was developed that included the cost of assembly, processing, and wholesale distribution of Class I milk within the state of Maine. Solution of the model with parameter values appropriate to current costs associated with these three aspects of the milk market yielded an achievable least cost allocation for performing the assembly, processing, and distribution of milk, adequate to meet demand, throughout the state. It is hoped that the model will prove a powerful planning and diagnostic tool.

Salt Marsh Dykes (Dikes) As A Factor In Eastern Maine Agriculture, David C. Smith, Anne E. Bridges

Maine History

The article discusses the prevalence of dykes found, primarily in Washington County, which had been built in the period 1790 – 1870 to reclaim salt marshes for agricultural purposes.

Tb104: An Analysis Of Moisture Content Variation In Eastern Spruce And Balsam Fir In Maine, James E. Shottafer, Allen M. Brackley

Technical Bulletins

This study was undertaken as an attempt to develop some estimate of the characteristic moisture content of green eastern spruce (Picea spp.) and balsam fir (Abies balsame a (L. ) Mill.), employing the methods prescribed under the Maine Weights and Measures Law. Certain procedural factors and conditions of growth were also considered, to evaluate their effect on the moisture content of the wood at the time of harvesting or shortly after cutting.

B782: Performance Evaluations Of Potato Clones And Varieties In The Northeastern States 1981, H. J. Murphy, L. S. Morrow, D. A. Young, R. A. Ashley, M. D. Orzolek, R. J. Precheur, O. S. Wells, R. Jensen, M. R. Henninger, J. B. Sieczka, J. S. Pisarczyk, R. E. Cole, R. E. Wakefield, R. J. Young

Bulletins

Cooperative variety trials were conducted at 33 locations to determine field, storage, and processing behavior of selected potato clones and varieties when grown under soil, climatic, and cultural conditions common to the potato growing areas of 12 cooperating States and the Province of New Brunswick, Canada. These trials are all contributions to Regional Project NE107 entitled, "Breeding and Evaluation of New Potato Clones in the Northeast Area."

Biological And Economic Effects Of Increasing The Minimum Legal Size Of American Lobster In Maine, James Acheson, R. Reidman

Marine Sciences Faculty Scholarship

The Northeast Marine Fisheries Board recently completed a comprehensive management plan for American lobster Homarus americanus, the most important provision of which is to raise the legal minimum size of lobsters from 81 to 88.9 mm carapace length incrementally over 5 years. Its objective is to increase egg production and recruitment, and thus reduce the likelihood of stock failure; economic benefits are anticipated for fishermen. However, a model used to analyze the frequency distributions of some 9,000 Maine lobsters demonstrates that in every year the legal minimum size is increased, smaller numbers and less weight of lobsters would be landed …

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

Bulletins

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 …
