An Apple Rest Model For Mild Winter Conditions, Jose Ignacio Del Real Laborde

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two areas of research are reported: an experiment on the effects of warm temperature prestratification treatments on seed dormancy and a new chill unit model.

Crabapple seeds (Malus sargentii Rehd.) were allowed to imbibe water and were given warm pretreatments at temperatures of 16, 20, 24 and 28C for periods of 3, 10, 20 or 30 days before cold stratification at 4C for 20, 40, 60, 80 or 100 days. Pretreatments resulted in increased chilling requirements for seedling emergence. A short chilling period (20 days) also altered the leaf area, shoot length, internodal length and root/shoot ratio of the …

Putting A Top Quality Forage Program Together On Your Farm, Richard Brown Phillips

Kentucky Alfalfa and Stored Forage Conference

You know most of us here, and I am including myself, really don't have a super talent for predicting the future with a great deal of consistency, however, our interest doesn't have to be in predicting, but rather, just primarily in considering potentials and opportunities in the future. What do you say, let's take a little time to look at some of the opportunities in the forage industry. The nation's No. 1 cash crop.

Sampling And Testing For Quality, Buddy Sims

Kentucky Alfalfa and Stored Forage Conference

The Kentucky Department of Agriculture is preparing to implement a unique and far-reaching program to provide forage producers with a detailed analysis of the quality of hay.

This program was mandated by the Kentucky legislature in 1988 as a means to enhance the marketing of Kentucky hay. A statewide hay testing and marketing program was recommended by a special legislative task force report issued in 1987 and has the endorsement of a number of agricultural organizations, including the University of Kentucky College of Agriculture and Kentucky Farm Bureau.

Marketing Kentucky Hay — A Reality, J. Kenneth Evans

Kentucky Alfalfa and Stored Forage Conference

As I write this in early December, Kentucky does not yet have a system for marketing hay. The above title reflects an attitude which positively expects a marketing system to be in place by the 1989 season. Many details of such a system have been discussed, some decisions have already been made and more will be made by the time you read this. Literally hundreds of decisions need to be made before hay is marketed in 1989. since these decisions will be made by a group of people (a producer Board of Directors and the KY Department of Agriculture personnel) …

Equipment And Chemical Advances In Harvesting And Storing Quality Hay, Michael Collins

Kentucky Alfalfa and Stored Forage Conference

In some areas of the country, many producers have gone to silage or haylage for storage of a portion of their forage. However, hay remains the most popular storage method for forage. Hay stores well for long periods and is better suited to cash sale and transportation over substantial distances than silage. Mechanical conditioning, which gained acceptance during the 1950's is probably still the greatest single change in hay harvesting and storage technology during this century. However, a number of other noteworthy changes and innovations have occurred in recent years which have helped to reduce the extent of losses during …

Alfalfa Hay: Quality Makes The Difference, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Alfalfa "Queen of the Forage Crops" is one of t.he most important forage legumes grown in the U.S. It can be grown over a wide range of soil and climatic conditions, it has the highest yield potential and the highest feeding values of all adapted perennial forage legumes. Alfalfa is a versatile crop which can be used for pasture, hay, silage, green-chop, soil improvements and human consumption (sprouts, etc.).

Changes In Mule Deer Size In Utah, Dennis D. Austin, Robert A. Riggs, Philip J. Urness, David L. Turner, John F. Kimball

Great Basin Naturalist

Trends in age-specific, eviscerated carcass weights were determined for hunter-harvested yearling and two-year-old buck mule deer. Carcass weights declined over an 11-year period from two areas of similar management, but with independenly collected data sets. Carcass weights also declined between the opening and second weekends of the hunt. Management implications are discussed.

The Development Of An Efficient Lupin Harvesting Front, E D. Blanchard

Journal of the Department of Agriculture, Western Australia, Series 4

Harvest losses represent a significant reduction in lupin production and farm productivity.

Since 1984, the Department's Farm Machinery Research and Liaison Unit at the Dryland Research Institute has studied the lupin harvesting operation to improve its mechanical efficiency. An experimental and a prototype harvesting front were built and tested in the field. Guidlines for efficient lupin harvesting were produced, and commercial modifications developed.

Water Relations Of Obligate Riparian Plants As A Function Of Streamflow Diversion On The Bishop Creek Watershed, S. D. Smith, J. L. Nachlinger, A. B. Wellington, C. A. Fox

Life Sciences Faculty Research

We investigated the water relations of obli-gate riparian plants on paired diverted and undiverted reaches on Bishop Creek, Eastern Sierra Nevada. Ri-parian plants on diverted reaches had reduced stomatal conductance and water potential compared to plants on undiverted reaches in a dry year, but not in a high runoff year. Juvenile plants on diverted reaches had reduced stomatal conductance and lower midday water potentials relative to surrounding mature trees, a trend that was not observed on undiverted reaches. Plants on diverted reaches possessed significantly smaller, thicker leaves and a reduced total leaf area relative to trees on streamside reaches. Reduced …

Riparian Plant Water Relations Along The North Fork Of The Kings River, California, J. L. Nachlinger, S. D. Smith, R. J. Risser

Life Sciences Faculty Research

Plant water relations of five obligate ripar-ian species were studied along California's North Fork Kings River. Diurnal stomatal conductance, transpi-ration, and xylem pressure potentials were measured throughout the 1986 growing season and in mid-season in 1987. Patterns were similar for all species although absolute values varied considerably. Maximum stomatal conductance occurred early in the day and season during favorable environmental conditions and decreased as air temperature and the vapor pressure difference between the leaf and air increased. Maximum transpiration rates occurred in mid-morning and mid-summer resulting in estimated daily water losses per unit sunlit leaf area of 163-328 mol H2O …

An Isotopic Analysis Of The Hydrology And Riparian Vegetation Water Sources On Bishop Creek, M. L. Space, J. W. Hess, S. D. Smith

Life Sciences Faculty Research

Five power generation plants along an eleven kilometer stretch divert Bishop Creek water for hydro-electric power. Stream diversion may be adversely affecting the riparian vegetation. Stable isotopic analysis is employed to determine surface water/ground-water interactions along the creek. surface water originates primarily from three headwater lakes. Discharge into Bishop Creek below the headwaters is primarily derived from ground water. The average δD and δ18O values are significantly different for surface water and ground water that an isotopic analysis can delineate between these two components of flow. Therefore isotopic shifts along the creek can determine gaining reaches. In addition, by knowing …

Erosion Potential Of Phomopsis-Resistant Lupins, D J. Carter, Paul Findlater

Journal of the Department of Agriculture, Western Australia, Series 4

During lupin harvesting, up to 20 per cent of the grain remains on the ground. This non-harvested or pilt grain is a valuable feed for sheep during early summer because the pods, leaf and stem generally provide little nutrient in the stubnbles. In addition, the more efficient the weed control, the less valuable are the stubbles.

The disease lupinosis caused by Phomopsis leptostromiformis restricts the amount of grazing from the lupin stubbles, and hence the risk of wind-erosion of stubble paddocks.

However, the introduction of lupin varieties moderately resistant to Phomopsis and with reduced potential to cause lupinosis means that …

Water Erosion On Vegetable Growing Land In South Western Australia, D J. Mcfarlane, N D. Delroy, H V. Gratte, J P. Middlemas, A M E Van Vreeswyk, I Mckissock

Resource management technical reports

The most serious erosion was found to be occurring in the Donnybrook area due to a combination of erosive winter rainfall, steep slopes and erodible soils. The most serious erosion was found to occur when storm runoff entered the vegetable plots from above, providing a transporting medium for the cultivated soil. A predictive model of erosion showed that soil texture, furrow slope, plot length, rainfall erosivity and canopy cover were significant factors affecting soil loss.
