Integrated weed management involving ways that biotic and abiotic factors affect weed population and community dynamics, and seed dormancy. Weed control recommendations, herbicide residues and resistant biotypes.
Examination of the factors and mechanisms which regulate seed dormancy, long-term storage and germination for seeds and other systems of plant propagation.
Integrative Crop and Soil Management
Evaluation of environmental, biotic, and management interactions that influence the growth, development, yield, and quality of corn, soybeans, and wheat. Management of forages for maximum economic returns and minimum soil erosion and nitrate losses with environmentally safe management practices.
Field experiments to develop methods for measuring and improving forage quality, production, and animal performance; best management practices for corn, soybeans, and wheat.
Examination of agronomic and economic sustainability of grass as a bioenergy source.
Crop Physiology and Molecular Biology
Mechanisms by which drought and other environmental stresses and climate change factors arrest sink-organ development (especially kernels and other storage organs), affect flowering and reproductive organ development, alter phytohormone levels and modify the expression of gene products involved in environmental responses. Mechanisms used to detoxify heavy metals; genes involved in synthesis, transport and regulation of interacting pathways.
Nutrient management using spatial information and field-based analytical instruments for use in precision agriculture.
