%X The Cd concentration in the seed of crops depends on various soil factors including parent material, texture, pH, soil redox, and salinity. Cadmium accumulation also varies among crop species and cultivars within a species. Cadmium and Zn may have either an antagonistic or a synergistic effect on plant uptake that can be influenced by the soil Cd and Zn concentrations. The objective was to determine the effect of Zn fertilizer additions on the seed Cd of nine crops commonly grown in North Dakota, USA. Studies were conducted at five North Dakota locations representing different soil series during 1994 and 1995. In Experiment 1, nine crops common in North Dakota were grown with and without the addition of 25 kg ha-1 Zn fertilizer. Among crops evaluated, the greatest seed Cd accumulation occurred in flax (Linum usitatissimum L.) followed by sunflower (Helianthus annuus L.), soybean (Glycine max [L.] Merr.), and durum wheat (Triticum turgidum L. var. durum). In Experiment 2, two durum wheats and one flax cultivar were grown under three Zn treatments of 0, 5, and 25 kg ha-1. In Experiment again flax had the higher seed Cd level compared with the two durum varieties. Based on the results from both studies, addition of Zn fertilizer did not consistently reduce seed Cd content, and even when statistically significant, the level of reduction was small and not likely to impact marketability of Cd accumulating crops such as flax, sunflower, soybean, and durum. La concentraci車n de Cd en semillas depende de varios factores, tanto del suelo como de la planta. Cadmio y Zn pueden tener efectos antag車nicos o sin谷rgicos en la absorci車n de la planta dependiendo de las concentraciones de Cd y Zn existentes en el suelo. El objetivo de este estudio fue determinar el efecto de la fertilizaci車n con Zn en la acumulaci車n de Cd en la semilla de diversos cultivos com迆nmente producidos en Dakota del Norte, EE.UU. Dos estudios fueron realizados en cinco localidades en Dakota del Norte que representaban diferentes series de suelo durante 1994 y 1995. Experimento 1, nueve cultivos fueron evaluados con y sin la adici車n de 25 kg Zn ha-1. Entre los cultivos evaluados, la acumulaci車n m芍s alta de Cd en las semillas ocurri車 en lino (Linum usitatissimum L.) seguido por girasol (Helianthus annuus L.), soya (Glycine max [L.] Merr.), y trigo duro (Triticum turgidum L. var. durum). Experimento 2, dos cultivares de trigo duro y un cultivar de lino fueron evaluados bajo tres tratamientos de fertilizaci車n, 0, 5, y 25 kg Zn ha-1. En este estudio nuevamente la acumulaci車n de Cd fue m芍s alta en lino.
