Nf02-503 Atrazine And Non-Atrazine Herbicide Comparisons In Conventional Till Corn, Fred Roeth, Alex Martin

Atrazine herbicide has been in an EPA special review since 1994 because of surface and groundwater contamination concerns. Beginning in 1997, we evaluated atrazine and non-atrazine herbicides in conventional tillage corn and no-till corn on university research farms at Clay Center and Lincoln, Nebraska. The objective was to compare some common atrazine and non-atrazine herbicides for weed control and crop response. Thirteen herbicides were selected to represent commonly used herbicide classes and treatment timings. This NebFact reports the conventional till results.

Imagine that you are entering an unknown field and would like to estimate the productivity of the unfamiliar soil. You may pick up a handful of soil to evaluate its color and texture. You also can feel how difficult it is to break a clod apart, roll it into a ball or press out a ribbon. After repeating this procedure at different field locations, soil depths and times, you get a feeling of both spatial and temporal soil variability. Some of this variability can explain the non-uniformity of crop yield. If you collect soil samples and send them to a …

Yield potential, pest resistance and seed price should be considered when selecting alfalfa varieties in Nebraska. The most important variety decision on many farms and ranches is the selection of alfalfa. The choice of alfalfa variety affects production for three to 10 or more years, whereas varieties of annual crops can be changed every year. Many alfalfa varieties are available from private and public plant breeders. Over the years, yield trials conducted at widely distributed Nebraska locations have tested most varieties sold in the state.
