Effect of Rye or Oat Cover Crop on Corn Growth and Development in a Rain-Fed, Wheat-Corn Rotation March 12, 2019

Cover crop species and planting date are two factors that could affect the following crop. In this student study the effects on corn of cover crop species and planting dates were evaluated.

Soil Microbial Communities under Cover Crops March 12, 2019

This study examined impacts of using a cereal rye cover crop in corn systems in eastern Nebraska and found that it boosted the microbial community in the upper two inches of the soil. This may improve soil aggregation, nutrient cycling, and other soil health benefits.

Planting Date Impact on Corn Growth and Ear Issues March 12, 2019

Do delayed planting dates affect plant growth (leaf height, stem diameter, and internode length) and ear formation issues in corn? See what this student researcher learned from trials conducted near Clay Center in summer 2018.
