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 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.

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.
