Full Length Transcript Promotor From Figwort Mosaic Caulimovirus (Fmv) And Use To Express Chimeric Genes In Plant Cells, Indu B. Maiti, Robert J. Shepherd

Kentucky Tobacco Research and Development Center Faculty Patents

Use of wild type and modified viral FLt promoters of FMV in the expression of chimeric genes in plant cells. The FLt promoter from FMV is modified with duplicated enhancer domains. The FLt promoter with its single or double enhancer domains is linked to heterologous coding sequences to form chimeric gene constructs. These genes have been shown to be expressed well in plant cells.


Optimization Of Solid-State Fermentation Parameters For The Production Of Xylanase By Trichoderma Longibrachiatum On Wheat Bran In A Forced Aeration System, Elizabeth R. Ridder, Sue E. Nokes, Barbara L. Knutson Nov 1999

Optimization Of Solid-State Fermentation Parameters For The Production Of Xylanase By Trichoderma Longibrachiatum On Wheat Bran In A Forced Aeration System, Elizabeth R. Ridder, Sue E. Nokes, Barbara L. Knutson

Biosystems and Agricultural Engineering Faculty Publications

The effect of aeration on the production of xylanase by Trichoderma longibrachiatum on wheat bran in a solid-state fermentation (SSF) system has not been investigated. This study was conducted to investigate the interactive effects of aeration, initial moisture content of the substrate, and depth of the substrate on xylanase activity produced in a tray fermenter. The experiment was conducted as a split plot experiment with factorial treatments and three replications of each treatment combination. The whole plot treatment was aeration rate (0, 2.9, 5.7 L/min/kg bran). Initial moisture content (45, 55, 65% w.b.) and depth of substrate (1.0 and 2.5 …

Modeling Surface And Subsurface Pesticide Transport Under Three Field Conditions Using Przm-3 And Gleams, Robert W. Malone, Richard C. Warner, Stephen R. Workman, Matt E. Byers Sep 1999

Modeling Surface And Subsurface Pesticide Transport Under Three Field Conditions Using Przm-3 And Gleams, Robert W. Malone, Richard C. Warner, Stephen R. Workman, Matt E. Byers

Biosystems and Agricultural Engineering Faculty Publications

Contaminant transport models should be evaluated over a wide range of conditions to determine their limitations. The models PRZM and GLEAMS have been evaluated many times, but few studies are available in which predicted movement in runoff and percolate were simultaneously evaluated against field data. Studies of this type are essential because pesticide leaching and runoff are mutually dependent processes. For this reason, PRZM-3 and GLEAMS were evaluated for their ability to predict metribuzin concentrations in runoff, sediment, subsurface soil, and pan lysimeters under three field conditions (yard waste compost amended, no-till, and conventional-till) on a Lowell silt loam soil. …

Marketing Alfalfa Hay: What The Consumer Demands, Tom Keene Feb 1999

Marketing Alfalfa Hay: What The Consumer Demands, Tom Keene

Kentucky Alfalfa and Stored Forage Conference

Anytime we address selling a product to the consumer; our first objective should always be to sell a quality product. However before we get into quality, I think we need to back up and understand that quality can vary from customer to customer depending upon the type of livestock he is feeding. For instance, if you are selling hay to a dairy operation, how is the hay being utilized? Is it being fed free choice? Is it going into a milking TMR (total mixed ration)? Is it going to feed young stock, breeding heifers, or sick animals? Each group of …

How I Produce And Market Alfalfa Hay, John Nowak

Kentucky Alfalfa and Stored Forage Conference

John Nowak was born March 22, 1947, in New York City and was raised in Westchester County, just north of New York City. After graduating from Colorado State University with a B.S. degree in farm and ranch management, he entered the U.S. Army. John served on active duty from 1969 until 1978. In 1975, his Army career brought him to Fort Campbell, Kentucky, and he began farming part-time in Christian County in 1976. As with many "start-from-scratch" farmers, John's first farming efforts involved producing burley tobacco during the years 1976 through 1979. In 1979, he began a cow-calf and backgrounding …

What I Have Learned From 4 Years Of Alfalfa Grazing Tolerance Variety Trials, Jimmy C. Henning, Robert Spitaleri, Garry D. Lacefield, Charles T. Dougherty

Kentucky Alfalfa and Stored Forage Conference

There has been interest in alfalfa varieties that would tolerate grazing for some time. The spreading type alfalfas (such as Rambler, Spredor 2, Travois) have long been generally promoted as being tolerant of grazing. Over the years, most selection for tolerance to grazing was done using frequent clipping to simulate grazing.

Studies conducted at the University of Georgia in the 1980's found that alfalfa varieties performed differently when grazed frequently compared to clipping frequently. This line of research eventually led to the release of 'AlfaGraze' alfalfa which was the first variety ever to be selected primarily by overgrazing by livestock. …


Practical And Economical Ways To Increase Alfalfa Hay Drying Rates, Michael Collins Feb 1999

Practical And Economical Ways To Increase Alfalfa Hay Drying Rates, Michael Collins

Kentucky Alfalfa and Stored Forage Conference

Hay stores well for long periods and is better suited to cash sale and transportation than silage and remains the most popular method for harvesting the alfalfa crop. Rapid drying reduces field losses by reducing respiration and by reducing the incidence of rain damage during curing. Because of these factors, harvest losses are greatest for very dry forage and are low for very wet material like direct cut silage. However, the latter is subject to excessive storage losses due to seepage and to quality deterioration. Storage losses are generally minimized by harvesting at low moisture levels.

Alfalfa Following Alfalfa: What Works And What Doesn't Work?, Monroe Rasnake

Kentucky Alfalfa and Stored Forage Conference

Farmers often would like to go directly back into alfalfa when an old stand plays out. However, research has shown that it is often difficult to get new stands established when this is done. Some of the problems may be attributed to weeds, insects and diseases that build up over time and become difficult to control. Another reason is that alfalfa plants have been shown to produce chemical compounds that can inhibit germination and growth of new seedlings. This effect is called allelopathy or autotoxicity.


Secrets To Getting A Good Stand Of Alfalfa, Jimmy C. Henning, Garry D. Lacefield Feb 1999

Secrets To Getting A Good Stand Of Alfalfa, Jimmy C. Henning, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Getting a good stand of alfalfa quickly is very important to Kentucky because it is the highest yielding, highest quality forage crop. In addition, it can be used in many different ways. Cool wet springs and hot dry falls have caused alfalfa seedings to fail in recent years. It would be easy to begin to believe that there was some 'magic' step or ingredient that has been missing. There are no magic steps to getting a good stand. Attention to a few major details can help maximize your chances of success.


What Grasses Work Best With Alfalfa?, Timothy D. Phillips Feb 1999

What Grasses Work Best With Alfalfa?, Timothy D. Phillips

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is the "queen" of forages, but many situations exist where it is desirable or necessary to grow alfalfa in a mixture with a forage grass rather in monoculture. Some of the reasons to grow grass with alfalfa are: improved yield (in terms of tons of dry matter produced), better seasonal yield distribution, better weed control, potential pest reduction, erosion prevention, bloat risk reduction, and accelerated hay-drying rates. Conversely, there are some factors that favor alfalfa monoculture. These include: lower forage quality, especially in terms of protein content; more difficult management requirements (herbicide use, fertilization, and harvest timing); and, lower …

Agronomy Notes

For several decades, farmers have experienced a common stand-establishment disease syndrome when spring-seeded alfalfa was followed by extended periods of wet weather. Seedlings affected by this syndrome exhibit severe stunting as well as yellowing and reddening of seed leaves (cotyledons), but they do not wilt or collapse, as they might from a damping-off disease. Commonly, the problem affects most or all of the field.

Based on research that began in the 1980's, we suspected that a fungus called Aphanomyces euteiches (hereafter simply called Aphanomyces) was responsible. This root-rot fungus can be found in the majority of alfalfa fields we …


Common Pokeweed Management In Corn And Soybeans With A Conservation Tillage Cultivator And Herbicides, Jonathan D. Green, William W. Witt Jan 1999

Common Pokeweed Management In Corn And Soybeans With A Conservation Tillage Cultivator And Herbicides, Jonathan D. Green, William W. Witt

Agronomy Notes

Common pokeweed (Phytolacca americana L.) is a warm-season perennial that grows well in nondisturbed areas such as fence rows and woodland borders. In recent years it has begun spreading to com and soybean fields where no-tillage practices are used. The deep taproot that is characteristic of common pokeweed, makes this weed difficult to manage, particularly in no-till plantings. The green leaves, fleshy stems, and purple berries of common pokeweed can inhibit the harvesting process and lead to discounts at the elevator for high moisture and stained seed.

The equipment industry has developed cultivators with large sweeps capable of operating …

Do Cover Crop Residue And No-Till Increase Poultry Litter Runoff?, M. A. Cooprider, Mark S. Coyne Jan 1999

Do Cover Crop Residue And No-Till Increase Poultry Litter Runoff?, M. A. Cooprider, Mark S. Coyne

Agronomy Notes

Manure and litter produced during broiler production are an environmental issue in Kentucky. The most common and practical disposal method is to apply the poultry wastes to pasture and crop land. If the wastes are incorporated by tillage immediately after application to crop land, nitrogen that might otherwise be lost by ammonia volatilization is conserved. However, incorporating wastes is not possible in no-till, which is a best management practice (BMP) used by 51% of Kentucky's farmers to control soil erosion. One question is whether surface application of poultry wastes onto no-till fields could increase fecal bacteria contamination of surrounding waterways …
