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

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