WICHITA, Kan. (AP) - Some Kansas growers are carrying out experiments they helped design, evaluating questions such as how different varieties, seeding rates, nutrients and other variables work in the fields on their farms. It's a partnership with Kansas State University under a program launched last season. About 20 farmers are participating in the program. University agricultural experts help the farmers design test plots and research so the experiments yield usable data, rather than simple observations or side-by-side trials that could be influenced by outside factors. So far, the studies have been conducted on soybeans, sorghum and corn. Kansas State is showcasing the program today (MON), hosting a tour of research plots in Saline County to give other producers and agronomists a chance to learn about the program.
