Continued use of atrazine for weed control in sweet corn has led to the evolution of atrazine tolerant weeds. The objective of the research was to evaluate efficacy and crop tolerance of several new herbicides and several herbicide combinations at sites with atrazine tolerant pigweed.

Nitrogen Contribution of Winter Annual Cover Crops to Sweet Corn Production in Western Oregon (1994)

Report to the Oregon Processed Vegetable Commission

John Luna

There is an increasing interest among Oregon vegetable producers in the use of cover crops to improve soil quality, provide biologically fixed nitrogen to reduce fertilizer inputs, and reduce ground water contamination. Because of the cost associated with cover crop establishment and spring incorporation ($25-40/acre), the ability to account for N contribution from the cover crop and reduce fertilizer inputs could help offset the cover crop costs.
