Abstract Existing Christmas tree production cost and return models do not link the number and average price of merchantable trees to management practices. This model simulates number and price as functions of specific management practices accomplished within a rotation. The model allows evaluation of the trade-offs between additional management costs and resulting revenues. Using average production costs, investment of typical and intensive management scenarios in Northern New England were simulated. Real rates of return from 6 to 18% were obtained depending on the management regime and market prices. North. J. Appl. For. 5:51-55, March 1988.

Weed management remains a high priority for organic farmers, whose fields generally have higher weed density and species diversity than those of their conventional counterparts. We explored whether variability in farmer knowledge and perceptions of weeds and weed management practices were predictive of variability in on-farm weed seedbanks on 23 organic farms in northern New England. We interviewed farmers and transcribed and coded interviews to quantify their emphasis on concepts regarding knowledge of ecological weed management, the perceived risks and benefits of weeds, and the perceived risks and benefits of weed management practices. To characterize on-farm weed seedbanks, we collected soil samples from five fields at each farm (115 fields total) and measured germinable weed seed density. Mean weed seed density per farm ranged from 2,775 seeds m−2to 24,678 seeds m−2to a soil depth of 10 cm. Farmers most often reported hairy galinsoga and crabgrass species (Digitariaspp.) as their most problematic weeds. The proportion of the sum of these two most problematic weeds in each farm's seedbank ranged from 1 to 73% of total weed seed density. Farmer knowledge and perceptions were predictive of total seed density, species richness, and proportion of hairy galinsoga and crabgrass species. Low seed densities were associated with farmers who most often discussed risks of weeds, benefits of critical weed-free management practices, and learning from their own experience. These farmers also exhibited greater knowledge of managing the weed seedbank and greater understanding of the importance of a long-term strategy. Targeted education focusing on this set of knowledge and beliefs could potentially lead to improved application and success of ecological weed management in the future, thus decreasing labor costs and time necessary for farmers to manage weeds.

Abstract Mixed hardwood-balsam fir stand management has been proposed as one silvicultural technique to reduce spruce budworm damage to balsam fir. An analysis was conducted using published results from New Brunswick, Canada, and northern New England, USA, to assess whether optimum hardwood levels (percent volume) could be determined for various levels of budworm defoliation. The goal was to maximize standing balsam fir volume and to determine trade-offs between reduced damage (hence reduced volumes losses) versus the amount of fir volume lost as a result of allocating growing space to hardwood species. Optimum hardwood levels depended on severity of budworm attack. Below 45% defoliation (5 yr average), the amount of balsam fir volume lost to increased hardwood growing space exceeded the amount of volume protected. As defoliation severity increased above 45%, the optimal hardwood levels increased. At severe levels of defoliation (> 75%) optimal hardwood content was approximately 50% of initial standing volume. The results suggest that mixed stand management can potentially reduce balsam fir volume losses in areas with frequent severe spruce budworm outbreaks. North. J. Appl. For. 16(1):19-24.

Several authors have suggested that a particular managerial component was needed before cost accounting could be fully used for accountability and disciplinary purposes. They argue that the marriage of managerialism and accounting first occurred in the United States at the Springfield Armory after 1840. They generally downplay the quality and usefulness of cost accounting at the New England textile mills before that time and call for a re-examination of original mill records from a disciplinary perspective. This paper reports the results of such a re-examination. It initially describes the social and economic environment of U.S. textile manufacturing in New England in the early nineteenth century. Selected cost memos and reports are described and analyzed to indicate the nature and scope of costing undertaken at the mills in Lowell, Massachusetts, in the late 1820s and early 1830s. The paper discusses how particular cost information was used and speculates why certain more modern procedures were not adopted. Its major finding is that cost management practices fully measured up to the business complexities, economic pressures, and social forces of the day.

Abstract The equine industry is highly variable with many different sectors and management practices. To determine how the public views common management practices and discipline-specific areas of the equine industry, an online study was distributed via email and social media over a 6-week period to U.S. residents over the age of 18 (n = 1,372). Survey questions included demographics, industry connection, definition of welfare and equine classification. Respondents were asked to select the most concerning option from a series of management-related scenarios. The production livestock and equine industries were then segmented by species or discipline, respectively, and respondents were asked which sector was most problematic. To analyze the data, frequency tables (Proc FREQ) and multinomial logistic regression (Proc LOGISTIC) were used in SAS 9.4 (Cary, NC) to test the factors associated with likelihood to select a given management scenario from each series (α=0.05). Respondents who were heavily connected to the industry were four times more likely than lightly connected individuals to select that a blanketed horse or unblanketed horse in 30°F weather with unlimited access to food and water equally presented no concern than to say that a blanketed or unblanketed horse in 30°F weather with unlimited access to food and water and were concerning (OR= 4.09; 95%CL: 2.08,8.04). Of the 1,244 respondents who answered, 563 (45%) said that the gaited horse industry is the most problematic equine industry compared to the racing industry (41%) and stock horse industry (8.7%). Understanding how the public perceives the various animal industries and management scenarios in relation to an individual’s connection to the industry, classification of equines and welfare definition is important to assess and improve educational intervention strategies.

The invasive fruit fly Bactrocera dorsalis poses a major threat to the production and trade of mango in sub-Saharan Africa. Farmers devise different innovations to manage the pest in an attempt to minimize yield loss and production costs while maximizing revenues. Using survey data obtained from Embu County, Kenya, we analyzed farmers’ knowledge and perception as regards the invasive fruit fly, their innovations for the management of the pest, and the determinants of their adoption and dis-adoption decisions of recently developed and promoted integrated pest management (IPM) technologies for suppression of the pest. The results show that farmers consider fruit flies as a major threat to mango production (99%) and primarily depend on pesticides (90%) for the management of the pest. Some farmers (35%) however use indigenous methods to manage the pest. Though farmers possess good knowledge of different IPM strategies, uptake is relatively low. The regression estimates show that continued use of IPM is positively associated with the gender and education of the household head, size of a mango orchard, knowledge on mango pests, training, contact with an extension officer, and use of at least one non-pesticide practice for fruit fly management, while IPM dis-adoption was negatively correlated with the size of the mango orchard, practice score and use of indigenous innovations for fruit fly management. We recommend enhancing farmer′s knowledge through increased access to training programs and extension services for enhanced adoption of sustainable management practices for B. dorsalis.
