Description

Most of the dairy farms in the Central Valley of Mexico have alfalfa and corn silage as major forages. Winters are mild, how­ever, yield of alfalfa is reduced and no corn can be grown. For­age crops as oats, annual ryegrass and common vetch have been grown successfully to supply winter forage (Avendano, 1978; Victoria, 1981). Annual rycgrass generally outyields oats, but a high input of nitrogen is required by annual rye grass (Ciane, 1978). The high cost of N fertilizers prevents their use and cheaper N sources should be sought. Legumes as common vetch grown with annual ryegrass can be a N source instead of a fertilizer. Herbage yield and quality of annual ryegrass grown with common vetch under different management strategies have not been extensively researched. The objective of the experiment was to determine herbage yield and crude protein of the mixture of annual rycgrass and common vetch at different seeding rates.
