Response of heterozygous and homozygous Imidazolinone-resistant spring wheat genotypes to Imazamox
Imidazolinone-resistant (IR) spring wheat (Triticum aestivum L.) was released commercially in Canada in 2004, providing growers with a new opportunity to selectively control a broad range of weeds in wheat, including volunteer cereals and annual grasses. Imidazolinone (IMI) herbicides inhibit acetolactate synthase in susceptible (S) plants, but IR wheat plants have an altered target site that ...

Behavior of atrazine in limited irrigation cropping systems in Colorado: prior use is important
Received for publication October 28, 2008. Glyphosate-resistant (GR) corn may be a major component of new cropping systems to optimize the use of limited irrigation water supply while sustaining production. Because atrazine is an important tool for residual weed control in GR corn, we examined atrazine binding to soil, dissipation, movement, and early season weed control in limited and full ...

Nitrogen contribution from red clover for corn following wheat in western Ohio
Inclusion of a winter legume cover crop into a crop rotation has been suggested as a method to provide a substantial portion of the N requirement of the following crop. While the benefits of winter cover crops such as reduced soil erosion, increased soil organic matter, and increased mulch cover have been well documented, the N contribution to the subsequent crop has shown to be variable. The ...

Jointed goatgrass management with Imazamox-resistant cultivars in a winter Wheat–fallow rotation
Jointed goatgrass (Aegilops cylindrica Host) is an economically important weed in winter wheat (Triticum aestivum L.)–fallow production regions of the United States. Few options exist for management of jointed goatgrass in winter wheat due to the close genetic relationship between the two species. This research evaluated use of imazamox herbicide ...

High yielding organic crop management decreases plant-available but not recalcitrant soil phosphorus
Phosphorus is a nonrenewable resource, raising concerns that agricultural practices may deplete reserves. Organic farming with low P inputs can result in deficient levels of plant-available phosphorus (available-P). The purpose of this study was to determine if common organically managed rotations are depleting P reserves or if large reserves still exist in unavailable forms. The research was ...
