Open Pollinated Forage Sorghums These forages are used for the same purposes as the hybrid forage sorghums, but have considerably lower seedling vigor (slower to germinate and emerge, less able to penetrate a soil crust) and lower overall yield potential than the Canex family of forage sorghum hybrids. Minimum germination soil temperature of 62 degrees and rising. Maximum planting depth 2 inches for most varieties in this class, Early Sumac should not be planted deeper than 1 1/2 inches. Early Hegari Released in 1940. Very early maturity variety with broad leaves and compact height of 3 to 4 feet at maturity. White grain with pink hew on open heads. Early Hegari will typically reach boot to early heading stage in 58 to 68 days, hard dough grain development in 88 to 98 days after emergence. Uses, Strategies and Suggested Planting Rates: Minimum germination soil temperature of 62 degrees and rising. Maximum planting depth 2 inches for most varieties in this class, Early Sumac should not be planted deeper than 1 1/2 inches.
