Narrative
Highly palatable native grass with good forage value. Rapid early germination and low dormancy make this release an excellent choice for quickly establishing native grass cover following disturbances such as mechanical brush control. Generally adapted to areas south of a line drawn from Del Rio to San Antonio, and east of Interstate Hwy. 37. Performs best on loam, clay loam, and sandy loam soils. Planting on very sandy soils is not recommended. Has successfully been established by planting coated and un-coated seed. Un-coated seed cannot be planted with a seed drill unless carriers are used to aid seed flow through drill tubes. Coated seed can easily be planted with a drill. Recommended seeding rate for pure stands is 1/2 lbs. pure live seed/acre. Seed should not be planted deeper than 1/4". Seed germination averages 43-63%, dormancy 9-19%, and pure live seed 40-60%. Uncoated seed has 677,000 seeds/pound; coated seed has 127,000 seeds/pound. Seed most easily harvested with a Flail-Vac, or other brush type harvester. Seed is produced from March-October in most instatnces in S. Texas. On 30" rowed plantings, harvested 4 times annually, average yearly yield is 50 lbs. pure live seed per acre. Mowing or burning plants when dormant stimulates new growth, prevents lodging, steminess, irregular maturity and loss of plant vigor. Infestations of rice stink bugs (Oebalus pugnax) can severely reduce seed yield if not controlled diligently in dry years. Seed easiily cleaned by hammer milling, and separation from stems and trash through # 2 or # 3 screens. Cleaning or attempting to clean seed to the bare caryopsis results in a significant loss of seed quality. Plantings using coated seed have shown better stand establishment than plantings with uncoated seed.

Description:
Composite release of 12 accessions from the Rio Grande Plains of S. Texas. Accessions selected from evaluation at 4 locations in S. Texas for plant vigor, seed production, forage production, and active sed germination. Each of 12 accessions was increased in isolation so that maximum genetic diversity was preserved in the initial release. Increase of each accession was done from the original field collection.
