Crop Production

 

Research Program

Improving the productive capacity of agricultural systems in southeast Kansas

My research program is designed to develop agriculture in the region to its full economic potential, incorporating sound ecological and environmental principles. Through on-farm and research plot experiments, we address the challenges facing the agricultural production system and farmers in America, and develop realistic production systems and management practices for transitioning agricultural systems in southeast Kansas and the U.S. towards sustainable production. Research areas include rain-fed resource-efficient cropping systems with wheat, soybeans, corn, sorghum, other small grains, and new or alternative crops, as well as cover crops and forages. Research is designed to explore cropping systems management and integrated crop/livestock production systems, including crop rotations, insect management, and disease and weed control. Research will delineate the economic feasibility and the environmental impact of alternative management practices and production systems. Crop sequences research will explore potential alternative uses of crops, identify promising new crops, provide long term benefits of crop rotations, and allow producers to capture optimal return on investment in highly volatile markets. Research is conducted both independently and in cooperation with faculty at the research center and in multiple on-campus departments.

  1. Delineate causes of the yield gap. Potential factors contributing to the difference in yield observed between production fields and the genetic potential of crops are determined from on-farm measurements and historical production records and reports.
  2. Improve net return of crop production. Alternative agronomic methods and conservation technologies are tested for their ability to increase return on investment and improve soil health and crop resiliency to variable growing conditions.
  3. Improve yield stability and resiliency of the agronomic system. Integrated animal and crop management scenarios are tested for their potential to improve overall agronomic system performance, economic return, and soil health, while controlling or reducing negative environmental impacts.
