Why do weed populations occur where they do, or do not, in agricultural areas. Research into the spatial distribution of weed species and how they correlate to soil and crop parameters observed in agricultural fields might provide insight to explain their distribution.
My research is focused on:
- Influence of cover crops on Palmer amaranth and kochia emergence, growth, and seed production in no-till crop rotations
- Influence of weed density on level of weed control with different herbicide rates
- Population dynamics of common sunflower and giant ragweed
- Weed species impacts on crop yields
- Palmer amaranth competition with corn in dryland and irrigated environments
- Palmer amaranth competition with grain sorghum at different nitrogen levels
