First-and second-year seedbank emergence of 23 summer annual weed species common to
US corn production systems was studied. Field experiments were conducted between 1996 …

Seed germination partly depends on both base temperature (Tb) and base water potential
(Ψb), which currently are known only for a small number of species. Laboratory experiments …

Bullied, WJ, Van Acker, RC and Bullock, PR 2012. Review: Microsite characteristics
influencing weed seedling recruitment and implications for recruitment modeling. Can. J …

Understanding the timing of weed emergence is crucial to effective management.
Management practices implemented too early may fail to completely control late-emerging …

To assess the competitive ability of plant species, ecologists describe many species from
contrasting habitats with traits that are proxies of ecophysiological functions whereas …

Stale seedbed preparation is a neglected agronomic strategy used to decrease weed seed
banks. The experiments aimed to verify the quantity-qualitative seed bank reduction after …

Enhanced understanding of soil disturbance effects on weed seedling recruitment will help
guide improved management approaches. Field experiments were conducted at 16 site …

A hydrothermal time model was developed to simulate field emergence for three weed
species in maize (common lambsquarters, johnsongrass, and velvetleaf). Models predicting …

Trials were performed to test the germination ecology of buried weed seeds as a function of
physical soil conditions such as of burial depth, texture, and compaction. Indeed, these …

Barnyardgrass is one of the most problematic weeds in Arkansas, and with the
documentation of herbicide-resistant biotypes, there is a need to gain a detailed …
