QUESTIONS THIS PROJECT WILL ADDRESS

  • What is the ideal planting date to maximize survivability of cover crops and biomass production?
  • How does cover crop planting date affect seeding rate?
  • Which cover crops work best in a soybean/corn rotation?
  • How does cover crop termination timing affect the following crop’s stand, growth and yield?
  • Cover crops are an important tool in preserving and increasing soil productivity, stewarding water resources, suppressing weeds and retaining nutrients. However, planting cover crops coincides with the busy harvest season. Also, research to influence best practices for successful cover crops has been limited across the vast Illinois growing environments.
  • This project will implement two different trials to inform how cover crops can best fit within a soybean/corn rotation:
    • Cereal rye after corn harvest before no-till soybean
    • Different clover species after soybean harvest before no-till corn
  • The trials will assess optimal planting windows, seeding rates, and termination timing to maximize overwintering; biomass production; and rotational crop stand, growth and yield.
  • To be able to determine the relationship between seeding rate and planting date on cereal rye stand quality and biomass production to better understand how to prescribe different seeding rates based on planting date and region to achieve a desired level of biomass. Also, this research will increase understanding of how these biomass differences influence soybean stand and yield.
  • To be able to determine the optimal date window for these clovers across the state for successful winter survivability and biomass production and performance and yield of the following corn crop.
  • The SOYLEIC breeding effort is a collaboration with breeders at other universities.
  • The Illinois breeding program collaborates with the Missouri Soybean Merchandising Council (MSMC) to coordinate testing and seed increases of elite SOYLEIC experimental lines to increase the speed that varieties are released.
  • The MSMC team also works with seed companies, processors and the food industry to increase demand for SOYLEIC oil.
