Grain Yield, Forage Yield, and Nutritive Value of Dual-Purpose Small Grains in the Central High Plains of the USA

Abstract

Dual-purpose small grains can extend the grazing period without compromising grain yield. In the Central High Plains of the USA, though vast acreages of wheat are planted each year, dual-purpose production is not common. This study evaluated the grain yield, forage yield, and forage nutritive value of two experimental lines along with a check cultivar from each of three species of small grains (rye, triticale, and wheat) in a replicated trial during 2008 to 2011. Average forage yields of rye and triticale lines were consistently greater than wheat. Forage yields of rye and triticale experimental lines were greater than the check cultivars. The check wheat cultivar Jagalene, however, produced more forage than wheat experimental lines. Wheat forage nutritive values were greater than rye, but similar to triticale. Grain yields of wheat were greater than triticale and rye. Small grains show potential for both forage and grain production in the Central High Plains.
