Hybrid Variation For Yield, Crude Protein, And Feed Value Of Corn, Z. Hu, C. G. Poneleit, K. O. Evans, Michael Collins, D. O. Liptrap Jul 1991

Hybrid Variation For Yield, Crude Protein, And Feed Value Of Corn, Z. Hu, C. G. Poneleit, K. O. Evans, Michael Collins, D. O. Liptrap

Agronomy Notes

The value of corn as a feed grain depends on the yield per acre, the protein content of the grain, and for some livestock, the lysine level of the protein. Most farmers are aware of yield differences among hybrid corn varieties but may not realize that protein content can also vary significantly. Grain protein level should be accounted for to determine how much protein supplementation will be needed to balance an appropriate animal diet. However, since corn protein is deficient in the amino acid lysine, which is essential for non-ruminant animals, lysine content as well as crude protein content should …

Grass Control In Corn With Accent And Beacon, W. W. Witt, Charles H. Slack, James R. Martin, Jonathan D. Green, M. A. Thompson

Agronomy Notes

The traditional method for grass control in corn is based on using herbicides applied to soil and incorporated before planting or to the soil surface after planting. This approach has been successful in controlling crabgrass, fall panicum and foxtails, but johnsongrass and shattercane control was sometimes inadequate.


Nitrogen Fertilizer Use By A High Yielding No-Till Corn Crop, Kenneth L. Wells, H. B. Rice, William O. Thom Apr 1991

Nitrogen Fertilizer Use By A High Yielding No-Till Corn Crop, Kenneth L. Wells, H. B. Rice, William O. Thom

Agronomy Notes

At the present time there is public concern about the effect which nitrogen (N) fertilizer use by farmers has on groundwater quality. This has resulted in research efforts to describe what happens to nitrogen fertilizer after it is applied to a crop. We have conducted a study for the past 3 years which enables us to make a reasonable estimate of how much fertilizer N is taken up by a high yielding corn crop. And, depending on whether the corn is harvested for silage or grain, we have estimated how much of the fertilizer N is removed from the field. …

Method For X And Y Spermatozoa Separation, Panayiotis M. Zavos, Karl A. Dawson Mar 1991

Method For X And Y Spermatozoa Separation, Panayiotis M. Zavos, Karl A. Dawson

Animal and Food Sciences Faculty Patents

A method for separating male and female determining spermatozoa includes the initial step of exposing freshly ejaculated spermatozoa in a substantially protein free diluent to an excess concentration of a monoclonal antibody directed against H-Y antigen that binds substantially exclusively with male determining spermatozoa. The method continues with the suspending of the exposed spermatozoa together with a conjugate of (1) an immunoglobulin G antibody that binds substantially exclusively to the monoclonal antibody and (2) an immunoabsorbant substrate in a substantially protein free diluent. This forms a conjugate/spermatozoa preparation. The method concludes with the recovering of the separated male and female …

Agronomy Notes

Cover crops are often used in Kentucky following the harvest of row crops such as tobacco, corn, and soybeans. Living cover crops can prevent erosion, reduce leaching of nutrients, and supply grazing, green manure, or a plant cover in which to no-till the following spring.


Curling Burley Tobacco From An Automated Harvesting System, Linus R. Walton, Larry G. Wells, James H. Casada Mar 1991

Curling Burley Tobacco From An Automated Harvesting System, Linus R. Walton, Larry G. Wells, James H. Casada

Biosystems and Agricultural Engineering Faculty Publications

If burley tobacco can be successfully cured at high density under waterproof covers in the field, a producer can expand production without the necessity of building new curing barns and can thereby more easily justify investment in the automated burley tobacco harvesting system (Wells et al., 1990a, b). Curing under waterproof covers in the field and curing on frames in the barn were evaluated over three curing seasons using two varieties (KY 14 and TN 86), two plant densities (32 and 43 plants/m2, 3 and 4 plants/ft2), position of tobacco on the frame (four levels ranging …

Grazing Alfalfa, Harlan E. White

Kentucky Alfalfa and Stored Forage Conference

Alfalfa has tremendous potential as a pasture plant. The characteristics such as high yields, high quality, persistence, and drought tolerance that make it so valuable for hay and silage production also make it extremely useful for grazing. Properly managed so it has adequate recovery periods after being grazed, it can provide grazing over a six-month grazing season.

Hay Testing And Marketing Update, Jimmy C. Henning

Kentucky Alfalfa and Stored Forage Conference

The hay testing program of the Kentucky Department of Agriculture continues to be actively involved across the state. Presently, there are stationary NIR labs in Frankfort, Glasgow, and Paducah. These labs operate somewhat differently from traditional forage testing labs because, for the price of analyzing the forage sample ($10), they will actually come to the farm and sample your hay! To get your forage analyzed, call the Department of Agriculture in Frankfort at 1-800-248-4628. They will find a convenient time to meet with you at your bam for sampling. The KDA. samplers will also rate your hay for several visual …

Management Options For Thinning Alfalfa Stands, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Alfalfa "Queen of the Forage Crops", is the most important forage legume grown in the United States. It is widely adapted and is grown over a wide range of soil and climatic conditions. Alfalfa has the highest yield potential and highest feeding value of all adapted perennial forage legumes. It is a versatile crop which can be used for pasture, hay, silage, green-chop, soil improvements and human consumption (sprouts, etc.). As a result of this crops many merits, especially yield, quality and versatile use, it can be used successfully in many animal feeding programs.


Alfalfa Varieties, Jimmy C. Henning Feb 1991

Alfalfa Varieties, Jimmy C. Henning

Kentucky Alfalfa and Stored Forage Conference

Few areas of forage agriculture are changing faster than variety development in alfalfa. The 1990 revised "Alfalfa Varieties" publication of the Certified Alfalfa Seed Council listed 26 new alfalfa varieties. Of the available certified alfalfa varieties, only 10 to 15% are public varieties. The remainder are developed and marketed by commercial companies such as Agripro, Dairy land, FFR, Pioneer, Vista, W-L Research, and others. The need for yield and performance information on alfalfa varieties therefore increases yearly. In 1990, the alfalfa variety testing program was re-started under the leadership of the University of Kentucky and Western Kentucky University (WKU). Three …


Procedures For No-Till Alfalfa, Harlan E. White Feb 1991

Procedures For No-Till Alfalfa, Harlan E. White

Kentucky Alfalfa and Stored Forage Conference

Technology is now available to successfully establish new stands of alfalfa without the need for tillage and preparation of a fine seedbed. Establishing new stands of alfalfa no-till essentially eliminates the threat of soil erosion while the new seeding is becoming established as well as the resulting ruts and gullies which damage equipment and can be dangerous to equipment operators. In addition to conserving soil, no-till seedings conserve moisture already present in the seedbed. This, plus the dramatic reduction in water run-off, improves the moisture supply for new seedlings. Less time and fuel are required to seed using no-till methods …

1990 Kentucky Red Clover Variety Test, L. M. Lauriault, Norman L. Taylor, Jimmy C. Henning, W. T. Edmonson Feb 1991

1990 Kentucky Red Clover Variety Test, L. M. Lauriault, Norman L. Taylor, Jimmy C. Henning, W. T. Edmonson

Agronomy Notes

Red clover is a high quality, shortlived perennial legume that is used in mixed or pure stands for pasture, hay, silage, green chop, and soil improvement. This species is adapted to a wide range of climatic and soil conditions and therefore is very versatile as a forage crop. Stands are generally productive for two or three years with the highest yields occurring in the year following establishment. Red clover is used primarily as a renovation legume for grass pastures. It is the dominant legume in Kentucky because it is high in seedling vigor, quality, yield, and animal acceptance.
