WORK TO BE UNDERTAKEN. See RESEARCH AND DEVELOPMENT PLAN (Attachment A to this SCHEDULE). Subject to the RESEARCH AND DEVELOPMENT PLAN, an overview of NOBLE work includes: Objective 1 (Establishment). In the initial trials to be established in the spring of 2006, we will evaluate planting date and [***] to control [***] and other warm season weeds in order to assess the best methods for establishing the crop. One of the most advanced of the [***] ([***]) will be used as the cultivar for conducting this trial.
