Abstract Heavy metal contamitantion of agricultural soils which could affect the foodchain has become one of the major concerns in the world in recent years Thisstudy investigated the effects of mixed cultivation of companion crops of bean soybean or mung bean on the uptake of cadmium by corn and sunflower from asoil contaminated with 5 mg kg cadmium For this purpose two separate potexperiments were carried out Each experiment was arranged based on acompletely randomized design with three replications Treatments in eachexperiment included co cropping of corn and bean corn and soybean corn andmung bean sunflower and bean sunflower and soybean sunflower and mungbean corn monoculture and sunflower monoculture Plants were harvested in thefirst experiment at vegetative stage 60 days after planting and in the secondexperiment at reproductive stage 90 days after planting The results show that atvegetative stage shoot dry weight of corn was decreased as a result of co croppingwith bean and soybean in comparison with corn monoculture At reproductivestage however corn shoot weight was decreased in all mixtures Sunflower shootweight was decreased when grown with any of bean soybean and mung beancompanion crops compared to sunflower monoculture in the plants harvested atboth vegetative and reproductive stages The concentration of cadmium in theplants harvested at vegetative stage was higher in corn grown with mung beancompared to that of corn monoculture and it was also higher in sunflower grownwith soybean compared to that of sunflower monoculture At reproductive stage however the concentration of cadmium in corn plants cultivated with any of bean soybean and mung bean companion crops was less compared to that of cornmonoculture At this stage also the concentration of cadmium in sunflower grownwith bean was less compared to that of sunflower monoculture The differencesbetween other mixtures with related monocultures were not significant in thisregard The concentration of zinc in the plants harvested at vegetative stage washigher in corn grown with mung bean compared to that of corn monoculture and itwas also higher in sunflower grown with soybean compared to that of sunflowermonoculture At reproductive stage however there were no significant differencesin terms of zinc concentration between co cropping treatments with relatedmonocultures The concentration of cadmium in the grains was lower in corngrown with soybean or mung bean compared to that of corn monoculture but thiswas not evident for corn and bean co cropping Mixed cropping of sunflower withany of bean soybean and mung bean companion crops also decreased cadmiumconcentration in sunflower grains There were positive correlations between thevariation in the cadmium concentration and the enzymatic activities ofglutathiyone peroxidase and glutathione reductase in both corn and sunflowerplants This was more pronunced for glutathiyone peroxidase The results obtainedfrom this study show that co cropping of bean soybean or mung bean companioncrops may significantly affect the uptake and distribution of cadmium and zinc andalso the activity of antioxidants enzymes in corn and sunflower plants
