Synopsis

Synopsis

Performance was best at elevations between 6,500 and 9,000 feet. At lower elevations initial growth was superior but survival was low because of high temperatures, drouth, and diseases. In higher regions the short day, low temperatures, and cloudiness hindered growth. Varieties originating nearest the tropical latitude grew more rapidly as seedlings and during establishment, flowered earlier and more profusely, had higher seed yields, and produced more total forage, but were less persistent.
