Use Of Bacterial Acetate Kinase And Their Genes For Protection Of Plants Against Different Pathogens, Arthur G. Hunt, Glenn B. Collins, Qingshun Li, Santanu Dasgupta

Kentucky Tobacco Research and Development Center Faculty Patents

An isolated gene fragment that encodes for acetate kinase, which confers disease resistance in plants is disclosed. The gene can be cloned into an expression vector to produce a recombinant DNA expression system suitable for insertion into cells to form a transgenic plant transformed with the gene fragment. A method for conferring disease resistance in plants that consists of growing plant host cells transformed with the expression system and expressing the gene conferring disease resistance to impart such resistance to host cells is also disclosed.

Use Of The Full Length Transcript (Flt) From Mirabilis Mosaic Caulimovirus To Express Chimeric Genes In Plants, Indu B. Maiti, Nrisingha Dey, Robert J. Shepherd

Kentucky Tobacco Research and Development Center Faculty Patents

A full-length transcript promoter from mirabilis mosaic caulimovirus (MMV) is identified and its DNA sequence given. The promoter functions as a strong and uniform promoter for chimeric genes inserted into plant cells. This strong promoter function is exhibited by histochemical assay in seeds and floral organs and by reproductive scores of transgenic plants including the promoter. The promoter preferably includes a 3′ untranslated region that may be from the MMV itself or from a heterologous source with respect to the promoter. The promoter is used in a chimeric gene and in methods for transforming plant cells to obtain transgenic plants, …

A Reduced–Cost Mechanized System For Handling And Curing Mechanically–Harvested Burley Tobacco, Greg A. Camenisch, Larry G. Wells, Timothy D. Smith, George A. Duncan

Biosystems and Agricultural Engineering Faculty Publications

An experimental system was tested in which mechanically harvested burley tobacco plants placed onto steel slotted receivers were retrieved from a field, transported to a field curing structure, and placed onto the structure for air curing by a single worker. The system consisted of a tractor–towed, trailer mechanism that engaged and hoisted loads of approximately 360 burley plants of approximately 1 Mg mass. Ten slotted steel rails, 3.05 m long, holding 36 notched plants were placed onto parallel wooden beams suspended at a height of 2.13 m by wooden posts set in the ground. Burley tobacco was cured in this …

Package Options For Alfalfa, Michael Collins

Kentucky Alfalfa and Stored Forage Conference

Most of the hay crop in Kentucky is harvested as dry hay and stored in round bales of various sizes for feeding on the farm. Most of the round-baled hay in Kentucky is used on-farm in feeding beef and dairy cattle. When alfalfa hay in round bales is left outside without protection from the weather, large losses in DM yield and in forage quality usually result. We routinely measure DM losses in the range of 20- 35% for a normal length hay storage season. Our research has shown that several economical storage options exist for protecting this hay from weathering. …

Marketing Kentucky Hay, Billy Ray Smith

Kentucky Alfalfa and Stored Forage Conference

The production of hay and pasture crops is essential to a profitable future for Kentucky agriculture. The Commonwealth ranked seventh in the nation in hay production in the year 2000 with 6.2 million tons. These forages provide the bulk of the feed supply for our livestock industry. In addition, a significant portion of our hay crop is marketed, both to in-state and out-of-state buyers.

Innovative Loading And Stacking Systems For Custom Hay Sales, Tom Keene

Kentucky Alfalfa and Stored Forage Conference

As the face of agriculture continues to change, so does the hay industry. What was standard operating procedure twenty years ago is now no longer economically feasible in the cash hay industry. This is especially true in the loading and stacking end of the business.

The business has changed because new technology along with the dramatic decrease in the availability of "hand labor" has helped to drive the need for new loading and stacking systems for the hay industry. These two phenomenon will continue to drive us toward total mechanization in the hay industry in fact many hay producers are …

Designing A Grazing System For Alfalfa, Ken Johnson

Kentucky Alfalfa and Stored Forage Conference

As we think about grazing alfalfa, we should decide why we are considering alfalfa and where it fits. I want to address some of these issues from my prospective as a grazer with several years experience and as an agriculture employee working with many grazers over the years. Alfalfa is the most productive, high quality grazing forage we can grow in Kentucky; we need to be using it more.

Grazing Alfalfa At The Western Kentucky University Farm, Byron Sleugh, Raquel Stiles, David K. Stiles, Amanda Canty, Curtis Mitchell

Kentucky Alfalfa and Stored Forage Conference

Alfalfa has been around for centuries. In all this time, it was used in many different ways to provide high quality forage to livestock. In fact, in the area where alfalfa originated, the word actually means "horse power". We have come a long way since then and alfalfa is used for a wide range of animals, from rabbits to rhinos.

In order to maximize the efficiency of utilization of alfalfa, it has become necessary to graze it. Grazing is preferred over harvesting and storage for several reasons: less equipment and thus lower cost, less harvest loss, and greater quality forage …

Managing Alfalfa For Yield-Quality-Persistence, Garry D. Lacefield

Advances In Alfalfa Breeding — What Will The Alfalfa Variety Of The Future Smell, Taste, Look And Act Like?, Jimmy C. Henning

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is the highest quality, highest yielding and arguably the highest value forage crop in Kentucky and in the US. It is useful as hay, haylage or pasture for a variety of species of livestock. It is well adapted to Kentucky and is an important part of the forage/livestock system.

Alfalfa breeders are actively working to develop varieties that will meet and exceed farmer expectations for yield and persistence. In addition, other traits are sought after to make the variety meet a special need or to have better marketability or attraction to the customer.

So what will the alfalfa of …

Stripping Burley Tobacco Into Grades, Gary K. Palmer

Agronomy Notes

Stripping burley tobacco into different grades has been a controversial topic for many years. The one-price years in the mid to late 80’s provided no incentive to the producer to strip into the appropriate grades. However, with the advent of contracting in the year 2000, many companies are suggesting four grades but still get a high percentage of three-grade tobacco. Tobacco companies can utilize a small percentage of mixed stripped tobacco, but the handling characteristics of the four stalk positions differ substantially during processing. As the companies make their blends, they look for specific characteristics that differ from grade to …

Phosphorus Soil Test Change Following The Addition Of Phosphorus Fertilizer To 16 Kentucky Soils, William O. Thom, James E. Dollarhide

“Burn Down” Management Of Winter Cereal Cover Crops For No-Tillage Burley Tobacco Production, Robert C. Pearce, David C. Ditsch, Jack M. Zeleznik, Wade Turner

Agronomy Notes

Recent developments in the design of no-till transplanters and significant improvements in weed control have made no-till tobacco production a feasible option for burley tobacco growers. No-till production reduces soil erosion when tobacco is grown on sloping land. This helps maintain the long term productivity of the soil and may provide the grower with more options for crop rotation, by allowing sloping land to be utilized for tobacco production.
