Riviera Bermuda Grass Seed
CROP FAILURE FOR 2019
Riviera bermuda grass is a new generation cold-tolerant turf-type seeded bermuda grass produced by Johnston Seed Company. Riviera is a revolutionary product developed by the Oklahoma State University Turf grass Development Team, with financial support from the United States Golf Association. It is the result of many years of selection for improved turf quality, cold tolerance, seed production and disease resistance in the transition zone. The transition zone offers a unique weather pattern with periods of extreme cold, extreme heat, and drought. Bermuda grasses produced in the Southwestern United States typically suffer from severe winter injury and cool-season grasses produced in the Northwestern United States struggle with the summer’s heat, drought and disease pressure. Riviera was developed for the turf manager who wants to manage grass and not constantly replant his grass.
The seed of Riviera is grown in Northwestern Oklahoma, not a place that first comes to mind when you think bermuda grass, at least not yet. Approximately 98% of the world’s production of bermuda grass is grown in Southern California and Arizona, a region where the climate is tepid. In contrast, Oklahoma is the land of extremes with temperatures ranging from 110 F with high humidity in the summer and reach below 0 F during the winter with extreme drought conditions.
Remarkably fast grow-in time: Riviera plantings on golf courses as far north as Warrensburg, Missouri have proven playable in only 7 to 8 weeks after seeding, with cart traffic allowed 8 to 9 weeks post seeding. Remarkably fast grow-in is easily achieved with good seed bed preparation, irrigation, and fertilization as needed to promote germination of seed and vigorous growth of plants.
Further extends the playing season: Riviera has provided excellent winter survival in the transition zone. Because of its excellent winter hardiness, Riviera can be seeded later in the bermuda growing season without suffering injury during the following winter. Add to that Riviera’s early green-up, and your course gains a serious business advantage in early, long and late playability.
Rich color and texture that boldly endure: Its top-ranked overall turf quality, rich green color, texture, uniformity and density are only the start. Riviera is also exceptionally tolerant of cold winters, drought during growing season and disease resistant. Moreover, it’s a leader in wear tolerance and divot recovery — highly resilient under heavy use and quick to recover from injury and abuse.
The viable alternative to cool-season turf: Compared to bermuda grass, cool-season grasses typically are more difficult to maintain because of less drought tolerance, greater susceptibility to many diseases and slower recovery from wear or divot injury. Now at latitudes where bermuda grass has never been an option, Riviera makes the benefits of bermuda grass possible — with cold tolerance that makes it practical. Riviera’s greater disease resistance can eliminate or dramatically reduce the need for and cost of applying fungicides. And its excellent drought tolerance can substantially reduce irrigation costs.
Its credentials are exceptional: Riviera was ranked first overall for five consecutive years in NTEP trials, acclaimed unsurpassed for bermuda grass wear tolerance at the University of Kentucky, and continues to be featured in articles in the golf course industry’s leading publications and online resources.
Seeding Rate & Planting: For best results with this grass, Riviera should be planted in areas of full sunlight when soil temperatures reach 65 F and are on the rise. Plant 2 to 3 pounds of coated Riviera seed per 1000 square feet in a well -prepared firm seedbed. Cover seed with no more than 1/4 inch of soil. Maintain adequate soil moisture around seed using frequent but light irrigation. Riviera is well adapted to the transition zone as well as all regions where Bermuda grass is currently grown. Coated seeds are easier to spread and retain moisture better which improves germination.
