Research fields and experiment stations play the long game
Tuesday, July 3, 2018
MANHATTAN, Kan. — Back in 1971, Idi Amin seized control of the African nation of Uganda. The 26th amendment to the U.S. Constitution lowered the voting age to 18. Norman Lear’s “All in the Family” debuted on CBS. And in a crop field near Topeka, Kansas State University researchers established a soybean fertility study that is still going strong today. Long–term experiments and studies are common in the field of agricultural research (no pun intended). Even a human that lives to 100 years of age is barely noticeable to a crop field that has been growing and nurturing food for one species or another, for perhaps thousands of years. University researchers established a soybean fertility study that is still going strong today. Learn more about K-State efforts...

Title: Biological Control of Insect Pests
Tuesday, February 23, 2016
Kansas grew more than 199 million bushels of sorghum for grain in 2014, enough to make it the highest-producing sorghum state in the nation. The invasive sugarcane aphid, Melanaphis sacchari, swept across much of the southern Great Plains in 2013 and caused serious yield losses in grain sorghum. Researchers at the Kansas State University Agricultural Research Center–Hays are working to decode nature and build and protect global food systems by identifying the natural enemies of sugarcane aphid and their roles in suppressing populations of this pest.
Managing Honey Locust Trees
Monday, Jan 4th, 2016
Honey locust is a deciduous tree that produces large brown seed pods and thorny appendages, and is present throughout most of the US. Dense stands of honey locust limit grass production, and if damaged or cut, honey locust is capable of producing large quantities of new sprouts from buds around the base of the trunk and along the lengths of the root system. Because of the propensity to produce sprouts, mechanical control measures also require herbicides to effectively result in tree death. Several herbicides have been labeled for honey locust control through various application techniques, including basal bark, thin line basal bark, cut stump, frill or girdle, and foliar applications.
