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 …


Transformation, Somatic Embryogenesis And Whole Plant Regeneration Method For Glycine Species, Glenn B. Collins, David Hildebrand, Paul A. Lazzeri, Thomas R. Adams, Wayne A. Parrott, Lynn M. Hartweck Jun 1991

Transformation, Somatic Embryogenesis And Whole Plant Regeneration Method For Glycine Species, Glenn B. Collins, David Hildebrand, Paul A. Lazzeri, Thomas R. Adams, Wayne A. Parrott, Lynn M. Hartweck

Plant and Soil Sciences Faculty Patents

A method for somatic embryogenesis of soybean, (Glycine max), Glycine soja and other Glycine species is provided using immature cotyledon tissue, preferably with the embryonic axis removed, comprising culturing said tissue on a medium containing auxin, preferably NAA at a concentration of at least about 15 mg/l. A further method for such somatic embryogenesis is provided wherein the culture medium contains a synergistically acting lowered carbohydrate and auxin concentration. Particularly embryogenic cells of such tissue are identified and improved maceration methods for contacting such cells with regeneration and transformation media are disclosed.

Methods for transforming somatic tissue from …


Method Of Reducing Odor Associated With Hexanal Production In Plant Products, David Hildebrand, Thomas R. Kemp, Roger Andersen, John H. Loughrin May 1991

Method Of Reducing Odor Associated With Hexanal Production In Plant Products, David Hildebrand, Thomas R. Kemp, Roger Andersen, John H. Loughrin

Plant and Soil Sciences Faculty Patents

A method of reducing the formation of hexanal by plant parts comprises breaking the plant parts, adding thereto an agent comprising lipoxygenase 3 enzyme and allowing the plant parts to remain in contact with the enzyme under conditions effective to attain the desired effect. A method of producing a low odor plant part meal or flour comprises breaking up the plant parts, adding an agent with lipoxygenase 3 enzyme and allowing the plant parts to remain in contact with the enzyme under conditions effective to attain the desired effect. An improved composition comprises a hexanal producing plant part meal or …


Grass Control In Corn With Accent And Beacon, W. W. Witt, Charles H. Slack, James R. Martin, Jonathan D. Green, M. A. Thompson May 1991

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 …

1990 Kentucky Winter Annual Legume Variety Test, L. M. Lauriault, Norman L. Taylor, Jimmy C. Henning, W. T. Edmonson

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 …


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.
