Crop Production & Range Management

Southeast Kansas is a highly diverse area. Much of the cultivated acreage is dominated by soybeans, corn, grain sorghum, and wheat. There is also a large amount of pasture and rangeland throughout the area. Southeast Kansas experiences the highest rainfall of the state. However, a large number of acres have limited water-holding capacity due to the shallow depth of topsoil. Therefore, producers have to manage both saturated and drought conditions, often in the same growing season.

The focus of applied research efforts aims to assist growers with problems relating to crop production and range management.

Research Projects
  1. Control and documentation of herbicide-resistant Italian ryegrass in wheat
  2. Feasibility of late planted double-crop sunflower
  3. Fungicide control of leaf diseases and head scab in wheat
  4. Managing fertilizer losses in wheat and corn in the high-rainfall environment of Southeast Kansas
  5. Sensitivity of alfalfa, red clover, white clover, and Korean lespedeza to pasture herbicides
  6. Weed and brush control on pasture and rangeland including sericea lespedeza, locust, and blackberry
  7. Weed control in corn, soybeans, sorghum, and wheat
