Alfalfa: The Queen Of Forage Crops, It Don't Get Any Better, Warren C. Thompson

Kentucky Alfalfa and Stored Forage Conference

For anyone who has grown or used alfalfa, there is no question but that alfalfa is the best forage crop they have dealt with. Perhaps that is one reason that we in professional agriculture have given so much special interest to the crop and why it is held in such high esteem and the position it demands in research and refinement investments over the years at the private and public sectors.

Alfalfa: Crop For The Future, N. P. Martin, R. D. Hatfield, D. R. Mertens, P. J. Weimer

Kentucky Alfalfa and Stored Forage Conference

Alfalfa use by dairy cattle has decreased in recent years because of excessive nonprotein nitrogen and low fiber digestibility. Ideal attributes for plant modification of alfalfa may include those that increase milk potential per acre and/or per ton, enhance digestible NDF, improve protein content and amino acid balance, improve agronomic traits for insect protection (safer forage supply), herbicide tolerance, virus resistance, drought tolerance, cold tolerance, improved mineral availability and enhanced yield. Progress in attaining these attributes will accelerate with the use of biotechnology. Livestock and hay enterprises will benefit from alfalfa that is less prone to contain mycotoxins or toxic …

History Of Roundup Ready Alfalfa, Mark Mccaslin

Kentucky Alfalfa and Stored Forage Conference

In late 1997 Forage Genetics International (FGI) and Monsanto began a joint project to develop Roundup Ready alfalfa. FGI collaborated with Montana State University to produce the first transgenic Roundup Ready alfalfa plants. The same CP4 glyphosate tolerance gene that has been effectively used in developing multiple other Roundup Ready crops, was successfully inserted into an elite FGI alfalfa plant in early 1998.

Growing Alfalfa For Wildlife, Don Ball

Kentucky Alfalfa and Stored Forage Conference

Alfalfa has long been recognized as a superb forage crop, which is why it is widely grown for dairy cattle, horses, sheep, and many other types of domesticated forage-consuming animals. Reasons for its popularity include wide adaptation, excellent nutritive value, good yield potential, perennial growth habit, a long growing season, and the fact that (in association with Rhizobium bacteria) it is a nitrogen-fixing legume that does not require periodic applications of nitrogen fertilizer.

Progress Towards Sclerotinia--Resistant Varieties, Paul C. Vincelli

Kentucky Alfalfa and Stored Forage Conference

Sclerotinia crown and stem rot (SCSR), caused by the fungus Sclerotinia trifoliorum, is one of the most important factors limiting the success of late-summer alfalfa seedings in the region. Infections of S. trifoliorum that progress into the crown of a fall-sown alfalfa plant can kill it during winter or spring green up. Stand losses by the following spring may be insignificant (1-3%) or nearly total, with 95-99% of the stand being dead (and often even rotted away and gone by spring green-up).

Alfalfa Hay For Horses (And Horse Owners!), Laurie Lawrence, Bryan Cassill

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is one of the most common hays fed to horses in Kentucky. Other hays that are often used include timothy and orchardgrass. As a legume, alfalfa has many nutritional advantages over timothy or orchardgrass. Alfalfa hay contains more protein and calcium than grass hays and thus is an excellent source of these nutrients for broodmares and growing horses. Another legume that may be useful as a hay for horses is red clover. Nutritionally, red clover has many of the same advantages as alfalfa. However, red clover has some non-nutritional characteristics which have traditionally limited its popularity with horse owners. …

Advances In Alfalfa Seed Coating, Bill Talley

Kentucky Alfalfa and Stored Forage Conference

Seed coating for alfalfa has been available since the mid to late 70’s. Over the last 30 years, advances in the industry have made it the choice of many producers. The purpose of the coatings at that time was mainly to add weight to increase the ballistic properties and to be a carrier for the rhizobia. Through research and new technology, coatings have evolved and shown great agronomic benefits. Seed coating can provide an opportunity to supply effective quantities of needed materials to each seed, which can influence both the physical property, and the microenvironment of the seed. Coatings can …

Impact Of Alfalfa In Lincoln County, Dan Grigson

Kentucky Alfalfa and Stored Forage Conference

Lincoln County is located 45 miles south of Lexington, Kentucky. It is part of 3 geographical regions of the state-the outer Bluegrass, the Knobs, and the Eastern Pennyroyal area. Thus the land ranges from moderate sloping fields that can be row cropped to fields that are nearly too steep to mow. The majority of the land is best suited for hay and pasture production. The soil fertility is moderately high with limestone, sandstone, shale and siltstone parent material. The land is very well suited to growing very productive forage crops.

Teaching Stand Management Using Virtual Alfalfa Plants, S. Ray Smith, Lars Muendermann, Av Singh

Kentucky Alfalfa and Stored Forage Conference

A ‘virtual’ alfalfa plant model was developed at the University of Manitoba in Canada as part of a comprehensive grazing research project. This model shows an alfalfa plant ‘growing’ on a computer screen and the plant’s response to grazing (similar to time-lapse photography). The original model was designed and constructed by Av Singh to show the research potential of visually modeling alfalfa plant growth. The ability to visually ‘grow’ a plant on a computer screen also provides an excellent teaching and extension tool.

Mole Drainage For Increased Productivity In The South West Irrigation Area, D L. Bennett, Richard George, Bill Russell

Bulletins 4000 -

Heavy soils, with low rates of soil-water movement, such as those found in the South-West Irrigation Area (SWIA), require closely spaced (2-6 m apart) subsoil drainage systems to provide sufficient water movement to control the effects of salt-waterlogging on pastures. Such close spacing using traditional buried pipe or tile drainage systems is impractical. As a result, mole drainage systems, used in other parts of the world for over 50 years, have gained popularity in the SWIA in recent years.

This Bulletin Farmnote reports the current ‘best-bet’ mole draining technique for SWIA conditions gathered from observations over a number of years …

Evaluation Of A Mechanical System For Reconstructing Soil On Surface Mined Land, John P. Fulton, Larry G. Wells

Biosystems and Agricultural Engineering Faculty Publications

The existence of excessive soil compaction has hindered the surface mining industry from returning land to pre−mining productivity after reclamation, especially on prime farmland soils. Heavy earthmoving equipment used during reclamation tends to generate root−limiting bulk densities that adversely affect plant growth thereby decreasing yields. Therefore, the purpose of this study was to evaluate a mechanism, called the ‘Soil Regenerator,’ which reconstructs soil media at minimum bulk density during surface mine reclamation. The prototype soil forming mechanism was mounted on the front of a conventional bulldozer. Soil was placed in long narrow windrows by a scraper or bulldozer. As the …
