In 2011, 21 on-farm cotton variety trials were conducted by the Mississippi State University Extension Service. 18 Roundup Ready Flex and 3 Liberty Link trials were conducted at locations throughout the Delta and hill regions of the state. The objective of our on-farm large plot testing program is to evaluate on-farm performance of commercially available cotton varieties. The on-farm testing program was designed as a supplement to small plot official variety trial data generated by MSU scientists. Results from these trials can be accessed through the link below.
