Large-Plot on-Farm Replicated Cotton Variety Trials in Oklahoma

Extension large-plot on-farm replicated cotton variety trials are an important component in germplasm evaluation.  Producer-cooperator and industry support for these trials is substantial.  These trials enable growers to observe on their operations the newest genetics and transgenic traits.  These trials are planted and harvested with producer equipment.  Multiple sites in Oklahoma have provided excellent information on which growers can base important variety selection decisions.  In 2013, large-plot replicated trials were established in several counties under non-irrigated and irrigated management.  Some sites were under no-till or strip-tillage conditions.  Results from these 3-replicate trials will be presented.
