However, fall seedings made after October 1 are likely to provide only winter cover and are slower to produce heavy spring growth. Excessive early spring top growth can create tillage problems if the crop is not incorporated by early to mid-May. This date will vary with the location and season. The seed is readily available and is usually sold in bushel quantities of 56 lbs. Use a seeding rate of 2 bushels per acre to establish.
Sudan grass is a summer annual that requires much heat for good growth.
Seedings made in late May or early June will guarantee a more vigorous growth than seedings made in late June or early July. Hybrid sudan grasses may have larger seeds and should be planted at heavy rates. Similarly, this summer annual will recover after being cut. Due to its tall growth habit, sudan grass should be cut back when growth exceeds 20-25 inches or plowed down if a second growth is not desired. Use a seeding rate of 80 lbs. per acre.
