MIXTURES OF ANNUAL CROPS FOR FORAGE IN CENTRAL ALBERTA

ing on both soils. Barley yielded less and was less competitive than oats. nailey-pea mrxtures produced higher yields than pure barley on Grey-wooded soil. Triticale and wheat were least competitive and produced low yields in mixtures. Average yields of sunflowers on Black soil were 3"3 times greater than on Grey-wooded soil, and yields were extremely variable over years. The effect of the relatively high fiber content of sunflowers at42% was reflected in their lower yields of aigesiiblJenergy. Legumes and their mixtures produced the highest yields of protein, with faba beans more pioductive on Black soil and peas better on Grey-Wooded soil. Usuatly the yields of mixtures were between or below the yields of components in pure stands.
