Nurse Cropping In Potato Systems, John M. Jemison Jr.
Nurse Cropping In Potato Systems, John M. Jemison Jr.
Cooperative Extension - Agriculture
In the summer of 2016, a study was conducted at the Rogers Farm in Stillwater, Maine to study the effect of short-term nurse crops on potato yield and quality. The study was designed as a randomized complete block design with six replications. The study compared two sowing rates (winter rye at 100 vs. 200 lbs/ac) to 20 lbs of annual ryegrass or a check plot (no nurse crop). In addition, each of the winter rye treatments was either killed with an herbicide prior to one-pass hilling or just hilled. To address the question of how long to grow a NC, …

Use Of Endomaxx Mycorrhizal Seed Treatment To Improve Potato Production In Maine, John M. Jemison Jr.
Cooperative Extension - Agriculture
With the increasing cost of fertilizer and the ever-decreasing supply of apatite worldwide, improving phosphorus (P) uptake should be a goal for all producers. Due to our high levels of iron and aluminum oxides in Maine soils, P efficiency is very poor. As a result, potato farmers tend to over apply P to ensure that their crop will have adequate P. Over time, this has led to increasing plant available soil test P levels. I recently requested the Maine Soil Test Lab director for potato soil tests over the past ten years. The percentage of soils testing above 40 lbs/ac …
The Enhancement Of Wild Bees (Hymenoptera: Apoidea) For Pollination Security, Eric M. Venturini
The Enhancement Of Wild Bees (Hymenoptera: Apoidea) For Pollination Security, Eric M. Venturini
Electronic Theses and Dissertations
The acreage of pollinator-dependent crops continues to expand across the globe. Simultaneously, honey bee hives – an annually rented commodity that growers rely on – are more expensive every year and in some cases, scarce. In response, pollinator-dependent growers seek alternative pollinators. One approach is installing bee pasture on farms, a strategy that enables systems-based farmers to become in-situ farm-scale habitat managers. This thesis first presents a review of the literature on bee pasture plantings and provides a brief overview of some methods for assessing their impacts on the pollinator community. There are three major gaps in current bee pasture …
An Economic Analysis Of Wild Bee Pollination In Lowbush Blueberry Production, Francis A. Drummond
An Economic Analysis Of Wild Bee Pollination In Lowbush Blueberry Production, Francis A. Drummond
University of Maine Office of Research Administration: Grant Reports
The purpose of this project is to determine the relative economic values of wild bee pollinators and commercial honeybees in lowbush blueberry production for individual Maine farms. The lowbush blueberry requires insect pollination in order to set fruit. Most farmers rent colonies of the non-native honeybee for pollination services, but wild, native bees are also effective pollinators. This project aims to provide growers with the means to assess the pollination needs of individual fields and to understand the levels of pollination possible if honeybees are not available. In order to achieve these goals, the relative abundance and species diversity of …

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 …

The bulletin reports on the first four years of the Maine Potato Ecosystem Project, a long-term, multidisciplinary study of alternative crop management strategies. The study site is a 15-acre tract on the northern boundary of the University of Maine's Aroostook Farm in Presque Isle, Maine, divided into 96 main plots that are grouped into four blocks. Each block is an area where soil survey data show similar soil characteristics. Thus, given the same production inputs, the crop output is expected to be the same on each plot within a block. Within each block there are 24 plots to which the …

Dickey-Lincoln School Lakes Project
Construction of the proposed Dickey-Lincoln School Lakes Project in Aroostook County, Maine will result in the isolation of an area of land due to the impoundment behind Dickey Dam. This land area is located between the United States - Canadian border, the Little Black River, the impoundment (elevation = 913 feet), the Big Black River, and the Shields Branch of the Big Black River, and comprises 183,768 acres of land. A previous report (ERT, 1977) determined the forest types within two miles of the impoundment but did not extend to the Canadian border. This report addresses the forest types
