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. Treatments will be as follows in a split-split plot design under irrigated soil in 2006: Planting Date: Feb ,April, June [***] treatment [***] treatment PRE: [***], [***], [***], [***], [***], [***], and [***] [***] ([***]): [***], [***], [***], [***], [***], [***], [***], [***], and [***]. Objective 2a (Establishment). In the fall of 2006 and spring of 2007, we will evaluate planting date and [***] to control [***] and other warm season weeds in order to assess the best methods for establishing the crop. Two of the most advanced of the [***] ([***] lowland) and ([***] upland) will be used as the cultivars for conducting this trial. Treatments will be as follows in a split-split plot design under irrigated soil in 2006 and 2007: Planting Date: Sept and May Species: upland and lowland switchgrass Seed treatment: [***], [***] ([***]), [***] ([***]), Banded [***] ([***]). [***] treatment PRE: [***], [***], [***], [***], and [***] The following measurements will be then be made: seedling counts 30 and 60 DAE and DM yield at end of growing season. Objective 3 (crop rotation). In the fall of 2006 and spring of 2007, we will evaluate switchgrass establishment where grassy weeds were controlled the previous year and where various [***] were grown and weeds were controlled Treatments will be in a strip-split design: Species: Upland and Lowland Switchgrass Planting Dates: Sept and May [***] annual reseeding [***]: [***] ([***], [***]). [***]: [***] Spray Selective grass [***] to control annual grasses

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 [***] herbicides to control [***] crabgrass and other warm season weeds in order to assess the best methods for establishing the crop. One of the most advanced of the [***] experimentals ([***]GA993) will be used as the cultivar for conducting this trial. Treatments will be as follows in a split-split plot design under irrigated soil in 2006: Planting Date: Feb ,April, June [***] treatment [***] Herbicide treatment PRE: [***]Atrazine, [***], [***], [***], [***]] amine, [***], and [***] [***] XXX ([***]): [***]Atrazine, [***], [***], [***], [***]amine, [***], [***], [***], and [***].

[***] Herbicide treatment PRE: [***]atrazine, [***], [***], [***], and [***] The following measurements will be then be made: seedling counts 30 and 60 DAE and DM yield at end of growing season. Objective 3 (crop rotation). In the fall of 2006 and spring of 2007, we will evaluate switchgrass establishment where grassy weeds were controlled the previous year and where various [***] Summer legume were grown and weeds were controlled Treatments will be in a strip-split design: Species: Upland and Lowland Switchgrass Planting Dates: Sept and May [***] Summer annual reseeding [***]legumes: [***] ([***], [***]).
