'Red River' Crabgrass Forage Production with Irrigation and Fertilization

Table 4. Estimated Comparative Yields between 'Red River' Crabgrass, 'Midland' Bermudagrass, and 'Plains' Bluestem¹

Forage Variety	Nitrogen per Acre	Actual Weight (Lb./Ac.)	Oven-Dry Lbs. Grass/ Lb. N	CP² (%)	IVDMD³ (%)	CP (Lb./Ac.)	IVDMD (Lb./Ac.)

Red River	202	9,560	47.3	15.4	73	1,472	6,979
Plains	202	10,767	53.5	11.5	65	1,238	6,999
Midland	202	10,241	50.7	15.6	64	1,598	6,554

¹These estimated yields are based on Huneycutt's data from table 3. Calculations were made assuming all grasses received the same nitrogen level, 202 pounds per acre, had the same quality composition, and produced a certain amount of grass per pound of nitrogen applied, as presented in table 3. ²Crude protein. ³In vitro dry matter digestibility.
