Effect Of Lime On No-Tillage Corn Yields, Robert L. Blevins, Lloyd W. Murdock
Effect Of Lime On No-Tillage Corn Yields, Robert L. Blevins, Lloyd W. Murdock
Agronomy Notes
The rapidly growing popularity and adoption of no-tillage systems of corn production have required us to re-evaluate some of our long established soil fertility practices and recommendations. Recent work by researchers at Kentucky and adjacent states show that the soil surface becomes very acid after a few years of continuous no-tillage corn production. This rapid decrease in soil pH is primarily associated with surface application of nitrogen fertilizers. Most lime recommendations and related research information for row crop production are based on plow-down application. Therefore, the effectiveness of surface-applied and unincorporated lime under no-tillage systems becomes a question of concern. …

G79-481 Setting A Realistic Corn Yield Goal (Revised January 2004), Achim Dobermann, Charles A. Shapiro
G79-481 Setting A Realistic Corn Yield Goal (Revised January 2004), Achim Dobermann, Charles A. Shapiro
University of Nebraska-Lincoln Extension: Historical Materials
Corn growers need to set a realistic corn yield goal in order to make sound decisions on corn hybrid, seeding rate, fertilizer application, and irrigation need. The goal should be the most profitable yield that can be expected for the particular set of soil, climate, and management practices. Yield goals should gradually increase over time, but cannot exceed the theoretical yield potential. This NebGuide discusses how to set a realistic corn yield goal by acknowledging climatic yield limitations of corn in Nebraska and the yield history in a field.
G79-471 Choosing Corn Hybrids, Lenis Alton Nelson
G79-471 Choosing Corn Hybrids, Lenis Alton Nelson
University of Nebraska-Lincoln Extension: Historical Materials
This publication explains what factors to consider and compare when selecting a corn hybrid and how to obtain recent hybrid test data. One of the most important decisions a corn producer makes is choosing the hybrid seed. Hundreds of hybrid names and numbers are advertised and offered for sale. Selecting the few that offer the greatest yield and profit potential requires time, effort, and study. This should be a continuous process for a corn grower because important information on new or established hybrids may be encountered at any time.
G79-430 Oat Production In Nebraska (Revised March 1992), Russell Moomaw, Charles A. Shapiro
G79-430 Oat Production In Nebraska (Revised March 1992), Russell Moomaw, Charles A. Shapiro
University of Nebraska-Lincoln Extension: Historical Materials
Information is provided for various oat production practices including seed selection, fertilizing, planting, weed control and harvest. Oats were among the first crops grown by pioneers who settled eastern Nebraska. As recently as 1950, Nebraska produced 2.7 million acres of oats. Acreage has declined steadily, however, and in 1990 there were just 300,000 acres. Oats are grown throughout the state, with the majority being in eastern Nebraska where the cool, moist climate provides for the best growth. The feed value of oats also favors its production in northeast Nebraska where swine, dairy cattle, and beef cattle production are heavy. An …
Relationship Of Weed Control And Soil Ph To No-Tillage Corn Yields, J. J. Kells, C. E. Rieck, Robert L. Blevins, Charles H. Slack
Relationship Of Weed Control And Soil Ph To No-Tillage Corn Yields, J. J. Kells, C. E. Rieck, Robert L. Blevins, Charles H. Slack
Agronomy Notes
Atrazine and simazine are used for selective control of a broad spectrum of weeds in corn. Over 80% of the U.S. corn production is treated with one or the other of these two s-triazine herbicides. In Kentucky they are used annually on over 800,000 acres of corn, including over 200,000 acres of no-tillage corn. When added to the soil these compounds are ultimately degraded to non-phytotoxic compounds. The rate of degradation is dependent upon the physical, chemical, and biological properties of the soil. Although atrazine and simazine are chemically similar, simazine is considered to degrade slightly slower than atrazine after …
