Book Description
Hard Red Winter (HRW) and Soft Red Winter (HRW) wheat classes (Triticum aestivum L.) and oat (Avena sativa L.) are commonly established as a source of winter and spring forage for cattle grazing in many regions of Texas and the U.S. Southern Great Plains. Small grains used in these grazed systems offer the flexibility of management for season long forage production or production of both forage and grain (dual-purpose). Many commercially available and experimental cultivars are continually evaluated on their ability to produce grain, but little yield data is available on wheat and oats under dual-purpose management systems. In forage production systems, soil fertility management is also an integral component in meeting specific yield goals that producers depend upon to sustain adequate animal performance. Current nitrogen (N) recommendations in Texas are based on heavy, moderate, and light levels of grazing. To address these issues, two-year studies were initiated at three locations in Central Texas. The objectives of these studies were; (1) to evaluate thirty wheat and ten oat cultivars based on forage production and grain yield to identify those best suited to dual-purpose management; (2) to determine winter wheat forage yield potential at varying levels of N fertility; and (3) to evaluate five minimally invasive and non-destructive methods of quantifying forage yield. Results from dual-purpose cultivar evaluations included significant differences in forage yield, nutritive value, and grain yield between cultivars and species. Overall, oat produced less forage than either class of wheat, but Mg content was generally higher in oat. For grain production, SRW performed better under irrigation, but in dryland situations both wheat classes performed equally. We also found that pre-plant N fertilizer significantly reduced stand establishment in dry environments. The 67 kg ha−1 pre-plant N and the 45 kg ha−1 top-dress rates produced the highest forage yield. Nutritive value generally increased as N application rate increased, even when no yield increase was observed. Hand clipping and canopy height both correlated very well with full plot harvest and visual ratings and NDVI had moderate relationships with full plot harvest. The relationship between ground cover and dry matter yield was variable and only weakly correlated. The electronic version of this dissertation is accessible from http://hdl.handle.net/1969.1/149556

Book Description
Small-grain cereals are widely adapted and used as annual cool-season pastures in the Southern Great Plains (SGP) of the United States, where livestock and forage production are the largest contributors to agricultural income. The advantage of growing small grains in the region is evident due to the widespread adoption and flexibility of production for grain only, forage only, or both grain and forage (i.e., dual purpose). Farmers in the SGP often prefer the use of small grains for dual purpose mainly because of alternative income options from livestock and/or grain, ensuring stable income especially when product prices fluctuate with market demands. Small-grain forage is exceptionally important during autumn, winter, and early spring when forage availability from other sources is low. By providing nutritionally high-quality forage, small grains minimize the need for protein and energy supplements. Besides being used for winter pasture, small grains also serve as cool-season cover crops. While small grains offer different advantages in the integrated crop-livestock system in the region, farming management practices can play an important role to maximize the benefit. The objectives of this chapter are to summarize the significance of small grains as winter pasture and highlight the production status of each small-grain species in the SGP of the United States.
