REPRODUCTIVE PERFORMANCE IN DOMESTIC RUMINANTS

Shipka, M. P.
Situation and purpose:
Producers of domestic ruminants experience economic loss associated with inefficient reproductive managment practices. The purpose of this research is to examine the effects of extreme temperature and extreme changes in day length on a seasonal basis on high latitude domestic ruminants.
Impact:
Successful reproduction in herds of ruminant animals produced on farms in Alaska is paramount for the establishment of livestock production in the north and the economic viability and sustainability of Alaska livestock production enterprises. Results of these studies demonstrate the effectiveness of reproductive management technologies and techniques that can be used to improve reproductive efficiency on Alaskan livestock farms and ranches. Demonstrating the effectiveness of applying reproductive management techniques to diversified livestock provides the farmer low-cost tools without risking private stock. Not all technologies translate equally well from traditional livestock to more exotic species and our ability to identify those that are effective under Alaskan conditions enhances the producers ability to maximize productivity, and hence profits. The market value of the offspring (~$5000/muskox; $1500/reindeer) is a significant portion of the income generated by the Alaskan diversified livestock industry. Synchronizing and timing estrus results in highly synchronized, predictable calving, reducing costly labor, and maximizing calf survival. Enhanced understanding of reproductive biology and reproductive management of reindeer and musk ox will enhance the productive capacity of these animals and the sustainability of enterprises producing these northern latitude adapted species in Alaska.

Innovative use of natural and supplemental light for high latitude crop production

Karlsson, M. G.
Situation and purpose:
Light varies naturally from sunrise to sunset. The amount, the type or quality, and the length of light during a day are essential for plant productivity and crop yield. The purpose of this project is to learn more about the best light conditions for optimum plant growth.
Impact:
Technical, yet simple, modifications to traditional greenhouse and controlled environment production systems can significantly improve and provide for increased crop returns. Adding incandescent lamps to improve the spectral distribution of high irradiance discharge lamps results in more rapid production and increased profits. Opportunities for year-round controlled environment production of perishable high quality produce and ornamentals will be greatly increased if recommendations for optimal amount, daily duration and quality of light are known and utilized.

Cultivar Selection, Production Methods, and Market Quality of Vegetables in Alaska

Leiner, R.
Situation and purpose:
Cool season vegetables can be produced in abundance during Alaska's summer, but production costs and changing markets continue to be a challenge to local growers. The purpose of this research is to study cool season vegetables and provide data on production methods that can be used to produce profitable crops in northern latitudes.
Impact:
Salad vegetables are produced locally in cool soil and long day conditions, and production methods can be tailored to the local climate. The potential for high quality of leafy green vegetables is improved by the short time in storage and transport. Residents and visitors can include local produce in salads as part of a healthy diet.

Project Number: ALK-01-09 Hatch
PRODUCTION PRACTICES, CULTIVARS AND DISEASE OF POTATO AND OTHER HORTICULTURAL CROPS

Leiner, R., Smeenk, P. J.
Situation and purpose:
Potato, well adapted to generally cool conditions, constitute an important part of the commercial vegetable industry in Alaska. Oplopanax horridus (devil's club), a medicinal plant indigenous to Alaska has potential for economic development. To remain competitive, potato growers need to enhance productivity and quality while maintaining or reducing the cost of production. Cultivation of O. horridus would offer opportunities for existing or new farmers, whereas management and harvest of natural stands would offer opportunities for those living in more rural areas of the state.
Impact:
Data from field trials can provide local growers with information relevant to selecting varieties and production practices that forecast good yields in long cool days. Fresh market potatoes are produced locally and include niche markets for red-skinned potatoes and larger markets for white and russet skinned potatoes

Project Number: ALK-01-11 Hatch
HORTICULTURAL CROP PRODUCTION FOR ALASKA

Holloway, P. S.
Situation and purpose:
Horticulture has been the largest agricultural industry in Alaska amounting to more than 80 percent of cash receipts for all agricultural crops in the state. The purpose of this study is to provide information on landscape plant hardiness, wildflower seeds, and commercial lingonberry production to satisfy consumer and commercial demand.
Impact:
The vegetable research is designed for small market gardeners and homeowners. It provides comparative trial information that is useful in developing regional truck farms and expanding produce choices as farmers markets. Field tomato trial information was requested by Territorial Seed Co., annual and perennial vegetable trial information as well as breeders seed for Yukon Chief sweet corn, was requested by Denali Seed, Anchorage The annual and perennial flower trial research is used by seed companies, nurseries, growers, landscapers and home gardeners to identify hardy perennials, disease resistant annual flowers for home and commercial production. Specific trial information was requested by Johnnys Selected Seeds (ME), Territorial Seeds (OR), Pan American and Ball Seed Co.(IL), and Goldsmith Seeds (CA). Wildflower germination experiments were requested by Seeds of Alaska (Kenai) and will benefit anyone interested in Alaska revegetation, wildflower meadows and home landscapes.

Cicer Milkvetch, Forage Galega, and Lupinaster Clover as Potential Forage Crops for Alaska

Sparrow, S. D.
Situation and purpose:
There are currently no perennial forage legume crops which are suitable for use in Alaska. This project will test three potential new perennial forage legume crops.
Impact:
This project will provide farmers in central Alaska with expanded options by providing information about management of new forage crops.

Project Number: ALK-02-05 Hatch
Management Practices for Forage and Turfgrass

Mitchell, G. A.
Situation and purpose:
Forage grasses and legumes for animal feed and turfgrasses for recreation have been tested over the years with comparatively few demonstrating survival of the harsh arctic winters. New varieties and improved management strategies must continue to be developed and tested to meet the requirements of this subarctic region. Many perennial grasses grown at lower latitudes do not perform well in most regions of Alaska. This project will identify grass varieties and management that will enhance agricultural and recreational uses.
Impact:
Extensive damage to golf course greens over most winters results in damages in the six-figure range statewide most years. Results of this research are of immediate use to golf courses in surrounding areas. We have taken this research to an on-site demonstration of best performing cultivars to a major golf course near Anchorage. Golf course superintendents have this information, at their request, and the results of this years very cold winter will be extremely important to future turfgrass selections. Damage to fairways, other sports fields, and lawns were also very costly in 2002 and results from these trials will be useful for assessing remediation requirements.

Project Number: ALK-02-06 Hatch
Selection, Variety Testing, and Evaluation of Cultural Practices for Alternative Agronomic Crops in Alaska

Zhang, M., Sparrow, S. D.
Situation and purpose:
Agricultural crop production in Alaska is limited by insufficient infrastructure and transportation. Since farmers can't compete in world markets they are interested in local niche markets. Reliable information on high value agronomic niche crops such as hulless barleys and oats, grass seed, and oilseeds as well as horticultural niche crops like flowers, vegetables and nursery plants is important to local producers trying to fill and sustain the demand from local markets for niche crops.
Impact:
This study is a continuing collection of information that provides yearly updates on new and better adapted crop varieties, the response of agronomic crops to dryland farming conditions, and provides a database for local producers to determine the economic viability for those crops. Future studies of the effects of irrigation on these agronomic crops will broaden this information database.

Project Number: ALK-03-02 Hatch
Black spruce forest soils in boreal regions of Alaska: Their characterization, organic carbon pool and relationship to forest management

Ping, C. L.
Situation and purpose:
The Arctic and Subarctic zones are expected to sustain the greatest impact in the wake of global climate change. Because of the vast acreage in Alaska and the potentially high C storage capacity in the boreal forest zone, an understanding of black spruce dominated sites is important for both ecological modeling and for land management. Very little information exists regarding the characteristics of soils associated with black spruce and a great need exists for a soils information baseline for modeling climate change, boreal forest management, and future soil inventory.
Impact:
Soils associated with black spruce froest have never been fully characterized. This study will provide the first data set of the soil properties in black spruce forest. The soil properties will be used ti interpret the factors affecting the forest growth and yield and also help to establish forest management guidelines.

Project Number: ALK-03-03 Hatch
Spatially Modeling the Distribution of Beef Cattle and Reindeer on Ranges at High Latitudes in Alaska

Harris, N. R.
Situation and purpose:
Alaska imports more than 90 percent of its food supply, including most red meat. With the current market structure, imported food is generally less expensive than Alaskan-grown food. This is principally caused by a lack of marketing and distribution infrastructures since existing ranching enterprises cannot support processing, distribution, and marketing investments. Much effort and research is currently being devoted to increasing production of meat animals, thereby stimulating economic development in Alaska.
Impact:
We expect that Alaskan livestock managers will be able to use the final animal distribution model to more effectively and efficiently manage their livestock. Through this increased efficiency, livestock producers will be able to develop strategies to allow animals to more effectively use landscape thermal patterns, thereby increasing animal weight gain and decreasing feed costs especially during the winter. The Alaskan livestock industry should prosper from this effect and grow to better provide for the needs of the growing state population. Through the use of the Alaskan animal distribution modeler, livestock impacts induced grazing and trampling will be mitigated and transferred to areas of the landscape that can better recover from their effects. This will protect the land base from degradation and decreased yields in the future thus leading to a more sustainable livestock production system. Management efforts to control erosion and point source pollution of waterways and riparian corridors caused by livestock can be model to predict the effects from these actions, thereby, allowing livestock managers to devote more energy and their limited funds to management techniques that have the prospect of being more successful. This will lead to reduce environmental liability and lessen the chances of litigation by citizens concerned with the ecological health of the watersheds.

MANAGING PLANT-MICROBE INTERACTIONS IN SOIL TO PROMOTE SUSTAINABLE AGRICULTURE

McBeath, J. H.
Situation and purpose:
In agriculture too many pesticides are being used and are detrimental to the environment and human health. To provide environmentally safe alternative means of disease control.
Impact:
The expectation of our research is to reduce the dependency of chemical fungicides in the control of plant diseases through the development of superior biological control agents and disease resistant varieties. T. atroviride is environmentally benign and safe to humans and animals.

Project Number: ALK-98-07 Hatch
FEASIBILITY OF INTENSIVELY RAISED REINDEER UTILIZING GRAZED FORAGES AND ALASKAN PRODUCED FEED INGRED

Shipka, M. P., Finstad, G. L.
Situation and purpose:
(not available)
Impact:
A palatable, digestible, and relatively inexpensive reindeer diet was developed using barley, brome hay and fish meal, feedstuffs readily available in Alaska. Female reindeer readily consumed this diet while exhibiting good weight gain and reproduction. Using barley as the main energy source in a diet for reindeer in Alaska is desirable due to its relatively low cost and availability ($153 US/metric ton; Delta Farmers Co-operative, 2003). Smooth brome grass (Bromus inermis) is successfully grown on rotational croplands in Alaska and was used as a fiber source in the reindeer diet. In Alaska, fish meal can often be priced competitively with soybean meal on a unit-protein basis ($0.71 per unit protein of soybean meal compared to $0.70 per unit protein of whitefish meal purchased in Fairbanks, AK). All components necessary to manufacture a balanced reindeer ration could be purchased from local producers and feed stores at a cost of $266.84US/metric ton for a maintenance diet and $283.29US/metric ton for a growth diet. Comparatively, a reindeer ration using components shipped into Alaska was available commercially in Anchorage, AK at a cost of $ 445.85 US/metric ton. Feed costs for reindeer can be greatly reduced if producers can mix their own rations using locally available feedstuffs. Reindeer fed a diet made from locally grown components exhibited good production. A local reindeer producer reduced his feed costs in half by using the diet formulations developed by this project.

Project Number: ALK-03-07 Animal Health
Mineral flux in Reindeer Animal Health

Finstad, G. L.
Situation and purpose:
Herd health is an important component of a productive and profitable reindeer operation in Alaska. Mineral nutrition, particularly Cu and Zn, has been shown to have profound affects on the functioning of ruminant immune systems and subsequent health. This information will benefit producers by establishing baseline seasonal mineral requirements in the diet of reindeer, reduce costs through least cost ration formulation, improve the energy balance of reindeer in winter and promote herd health through a proper functioning immune system.
Impact:
Reindeer typically lose weight during winter even if fed ad lib. The initial results of this study suggest reindeer are excreting more Cu and Zn than absorbing from a fed diet. The concentrations of trace minerals, Cu and Zn, required in the winter diet of reindeer may be well below that recommended by the NRC for ruminants. Supplemental trace minerals are added to the reindeer ration at a cost to the producer. Reducing the concentration of unnecessary minerals in the winter diet of reindeer will reduce feeding costs for the producer.

New Crops Opportunity

Lewis, C. E., Knight, C. W.
Situation and purpose:
New markets appear feasible for crops that are in the experimental phase of production or can be wild-harvested in Alaska. Value-added processing of agricultural crops in Alaska will contribute to the state's economic diversity.
Impact:
Thirteen new crop opportunity projects were funded. Valuable data was collected in all projects, with new crop potential for Alaska clearly identified in the Peony, Devils Club, Baby Green and Oilseed projects. New greenhouse and turfgrass grower information and valuable new data on black spruce has been made available. We have developed baseline data, which is moving us into competitive grants, providing direction for: our delegation in investments in UA research; federal and state policy regulation; and individual entrepreneurs. Other very valuable impacts of the New Crops Opportunities to our program include the synergy that has developed among researchers, new research directions, and the opportunities that have become available to students.

New Crops Opportunities

Lewis, C. E.
Situation and purpose:
New markets appear feasible for agricultural crops and crop derivatives, animal production, and products from the forest that are in the experimental phase of production or can be wild-harvested in Alaska. Value-added processing of agricultural crops in Alaska will contribute to the state's economic diversity.
Impact:
This research gives new direction for Alaska agricultural research and industry, enabling the state to compete in the global marketplace. The new products being developed will fill niche markets, both national and international. Controlled environment research is providing information for successful flower and fruit production to greenhouse growers. Information is now available which can assist state land managers determining wood refinery feasibility for small diameter wood and slash and commercial birch bark harvest. Baseline information for revegetation specialists working along roadsides and airports is now available. As this research continues, we expect to provide information on antioxidant levels in Alaska berries, vegetables and native plants, revegetation, livestock reproduction, commercial birch sap production, and suitable plant species for Alaska.

Project Number: ALK-02-09 Special Grant
New Crops for New Markets

Lewis, C. E.
Situation and purpose:
Value-added processing of the new and traditional raw materials from Alaska's farms and forests will contribute to the state's economy. There are a number of new agricultural and forestry products produced in Alaska that show promise in traditional consumer markets, niche markets, and emerging markets.
Impact:
The baby greens project provides market-based information on production, demand, and consumer preferences, which can be used by growers to develop niche markets. The reindeer study focuses on management tools that can assist farmers in maintaining adequate stock of healthy, reproductively sound, males. Rutting males are extremely dangerous to both humans and other male reindeer and very destructive to property. Use of MGA may offer a means to control rutting behavior in males without interfering with future breeding use of that male. This project was initiated at the request of Moose Creek Farms and will provide an environmental protocol for the production of lingonberries by tissue culture that will lead to the development of a cultivated crop. This project will provide growers and users of Alaska wheat with information with regard to appropriate uses of Alaska Grown Ingal Wheat. While baking tests may have proven that Ingal Wheat is not well suited for food, the feed tests show that it may be a valuable alternative feed source for animals. The boreal forest region as a whole generates a global benefit in the form of carbon. Forest scientists and managers can obtain a net transfer of benefits (payments or offset credits) into the region if they can identify where the uptake occurs, how much occurs, and how forest management actions can sustain or enhance carbon uptake.

Project Number: ALK-03-10 Special Grant
New Crops Opportunities IV

Lewis, C. E.
Situation and purpose:
The goal of the "New Crop Opportunities" sequence of projects is to investigate new opportunities in crops and livestock, value-added processing, and markets for Alaskan agricultural products including those from the forests of Alaska. The thread that connects these seemingly diverse projects is the economic viability of products that have potential to provide entrepreneurs with opportunities to enter markets that would not be available to them without the applied research information that the proposed projects provide. These opportunities vary from very specialized products that may remain at the small business level, to those that could provide opportunities on a large scale in national and international markets.

Project Number: ALK-03-13 Special Grant
Controlled Environment Production of Small Fruits, Berries, Floral Crops and Greenhouse Adapted Food Crops

Karlsson, M. G.
Situation and purpose:
The short growing season for traditional production and crop systems puts severe challenges and limitations on time frames, experimental setup and repeatability for research and training activities. A controlled environment facility will enable year-round work, establishment of quantitative procedures and the testing of hypothesis that may be difficult or impossible in natural ecosystems.
Impact:
Controlled environment production systems provide exceptional opportunities in areas with inclement climatic conditions to meet year-round local demand for perishable high quality fresh market berries, vegetable and floral crops. Recommendations tailored to northern conditions, infrastructure and climate are indispensable to the successful management and operation of controlled environment enterprises. To properly plan, market and schedule production, economical analyses and specifics of local market demand, consumer preferences and profit margins are needed for various crops suited to controlled environment production systems.
