Management of a double purpose wheat is not easy. Therefore, a simpler management alternative was studied: the mixture of two wheat varieties, one of long- cycle and the other one of short-cycle. Research was effected in the experimental field of the Asociación of Cooperativas Argentinas (38º 36´S, 61º 58´O and 122 m asl), 15 Km SW of Cabildo (Bs. As), in the semi-arid wheat subregion V S. At this place, forage and grain production of a suitable double-purpose wheat (ProINTA Pincén) was compared to its mixture with a short-cycle variety (Cooperación Calquín), either in the same or alternating rows. Forage production of the double-purpose wheat was overcome (P <0,01) in 128% and 98% by the mixtures. Grain production of the double- purpose wheat was 55% greater than that in the mixtures.
