Abstract

Spring barley can be used to diversify and intensify winter wheat-based production systems in the U.S. Pacific Northwest. The objective of this study was to describe the effects of tillage system and weed management level (WML) on weed control and spring barley grain yield when grown in a winter wheat-spring barley-spring dry pea rotation. A long-term integrated pest management field study examined the effects of three WMLs (minimum, moderate, and maximum) and two tillage systems (conservation and conventional) on weed control and barley grain yield. Total weed biomass at harvest was 8.0 and 59.7 g m−2 for the maximum and minimum WMLs, respectively, in the conservation tillage system, but was similar and averaged 12.2 g m−2 for all three WMLs in the conventional tillage system. Despite greater weed biomass with minimum weed management in the conservation tillage system, barley grain yields averaged 5,060 and 4,780 kg ha−1 for the conservation tillage and conventional tillage systems, respectively. The benefits of conservation tillage require adequate herbicide inputs.

La cebada de primavera puede ser usada para diversificar e intensificar los sistemas de producción basados en trigo en el Pacífico Noroeste de los Estados Unidos. El objetivo de este estudio fue describir los efectos de los sistemas de labranza y el nivel de manejo de malezas (WML) sobre el control de malezas y el rendimiento de grano de cebada de primavera cuando se produjo en una rotación de trigo de invierno-cebada de primavera-guisante de primavera. Un experimento de campo de manejo integrado de plagas de largo plazo examinó los efectos de tres WMLs (mínimo, moderado, y máximo) en dos sistemas de labranza (conservación y convencional) sobre el control de malezas y el rendimiento de grano de la cebada. La biomasa total de malezas al momento de la cosecha fue 8.0 y 59.7 g m−2 para el WMLS máximo y mínimo, respectivamente, en el sistema de labranza de conservación, pero fue similar y promedió 12.2 g m−2 para todos los tres WMLs, en el sistema de labranza convencional. A pesar de que hubo una mayor biomasa de malezas con el manejo mínimo de malezas en el sistema de labranza de conservación, los rendimientos de grano de la cebada promediaron 5,060 y 4,780 kg ha−1 para los sistemas de labranza de conservación y convencional, respectivamente. Los beneficios de la labranza de conservación requieren insumos adecuados de herbicidas.
