Department of Agronomy
Corn Yield Response to Various Management Practices
Evaluate corn response to intensified management practices such as the use of fungicides, increased seeding rates, early season micronutrient applications and late season nitrogen applications.
Contact: Dan Quin, Malena Bartaburu Silva, Agronomy
Corn Yield Response to Planting Date x Hybrid Maturity x Fungicide
Evaluate corn response to these practices that affect have potential to affect yield - planting date, maturity of a hybrid, and applications of fungicides in a growing season.
Contact: Dan Quin, Darcy Telenko, Agronomy
Soybean Yield Response to Various Management Practices
Evaluate soybean response to intensified management practices such as various fertilizer application and rates, the use of fungicides, pesticides, and foliar fertilizer.
Contact: Shaun Casteel, Agronomy
Soybean Yield Response to Cereal Rye combined with Nitrogen and Sulfur Applications
Sulfur deficiencies in soybeans have been demonstrated since 2016 in Indiana. In 2018, several fields were responsive to sulfur when the normal rule of thumb would say “no”. The current hypothesis is that the biomass created a micro-environment that slowed mineralization (cool, wet) and higher C content immobilized the sulfur (and nitrogen).
Contact: Shaun Casteel, Agronomy
Soybean Yield Response to Sulfur Applications and Nutrients Carryover into Corn
Evaluate soybean response to sulfur fertilization and next year corn response.
Contacts: Bob Nielsen and Jim Camberato, Agronomy
Indigenous Soil Potassium (K) Supply, Fertilizer K Use-efficiency, and K Budgets in Indiana Soybean Production
Evaluate the agronomic efficiency of currently recommended Potassium (K) fertilizer rates and evaluate theoretically improved soil K tests for the ability to predict soil K supply. Contact: Jim Camberato, Agronomy
SARE - Ecology of Organic Cropping Systems
Evaluate various organic cropping systems and their effect on weed, insect, and pathogen pressure on corn, soybeans, and other small grains
