Controlling Barnyardgrass with Corn Hybrid Selection
Barnyardgrass is a summer annual grass weed with a global impact on corn production. Yield losses due to barnyardgrass competition have been estimated up to 45% or more for crops such as cotton and corn. Besides corn, it can also be a serious weed pest in rice, soybean, sugarbeet, cotton, and corn. Integrated weed management techniques can be used for control of barnyardgrass in corn. High ...

Can changes in canopy and/or root system architecture explain historical maize yield trends in the U.S. corn belt?

In this study we used a modeling approach to examine whether changes in canopy and/or root system architecture might explain the observed trends. A maize crop model was generalized so that changes in ...
