Abstract

Crop diversity may improve tolerance to weed interference and reduce the need for herbicides. This experiment measured weed interference in corn as affected by the preceding crop in two studies. The first study, based on interference of the resident weed community, compared dry pea, soybean, canola, and spring wheat for effect on corn tolerance to weeds. Prominent weeds were green and yellow foxtail. The second study examined corn tolerance to a uniform infestation of foxtail millet as affected by dry pea, soybean, spring wheat, and corn as preceding crops. Each plot was split into weed-free and weed-infested subplots in both studies. Corn was most tolerant to weed interference following dry pea; compared with soybean, dry pea improved corn tolerance more than twofold. Corn also yielded the highest in weed-free conditions following dry pea; compared across 4 yr, corn yielded 7 to 23% more following dry pea than following either soybean or spring wheat. Crop diversity has helped producers reduce herbicide inputs in the Great Plains and may provide an additional benefit of reducing weed impact on crop yield.

La diversidad de cultivos podría mejorar la tolerancia a la interferencia de malezas y reducir la necesidad del uso de herbicidas. Este experimento midió en dos estudios la interferencia de malezas en maíz y de cómo fue afectada por el cultivo precedente. El primer estudio, basado en la interferencia de la comunidad nativa de malezas, comparó el efecto que tuvieron el guisante seco, soya, canola y trigo de primavera en la tolerancia del maíz a las malezas. Las malezas más abundantes fueron Setaria viridis y Setaria glauca. El segundo estudio examinó la tolerancia del maíz a una infestación uniforme de Setaria italica y cómo fue afectada por el guisante seco, soya, trigo de primavera y maíz como cultivos precedentes. Cada parcela se dividió en sub-parcelas libres e infestadas de maleza en ambos estudios. Sembrado después del guisante seco, el maíz fue más tolerante a la interferencia de la maleza. En comparación con la soya, el guisante seco mejoró la tolerancia del maíz más del doble. El maíz también tuvo el mayor rendimiento en condiciones libres de maleza, seguido por el guisante seco. Promediando los cuatro años, el maíz rindió de 7 a 23% más al ser sembrado después del guisante seco que después de la soya o del trigo de primavera. La diversidad de cultivos ha ayudado a los productores a reducir las aplicaciones de herbicidas en las Grandes Planicies y puede proporcionar un beneficio adicional al reducir el impacto de las malezas en el rendimiento del cultivo.
