Differential response of Palmer amaranth (Amaranthus palmeri) seed germination and seedling emergence under variable environmental conditions

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Palmer amaranth (Amaranthus palmeri S. Watson) is a eudicot weed that is considered as one of the most problematic weed species. It is reported to overcome several environmental and management stresses under field conditions. Research was conducted in a growth chamber and greenhouse to evaluate the effects of different stress parameters such ...

Crop yield and weed community response to cover crop termination strategies under organic management in the US Mid‐South

open access: yesAgronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract Weed management is still a main drawback for the wider adoption of organic cropping systems in the Mid‐South. Holistic cropping management, which involves a combination of cover cropping, tillage practices, and integrating crop and livestock systems, is an option to overcome this challenge.
