Resumo: This work was carried out in a greenhouse to evaluate the growth and Zn efficiency of maize cultivars of different technologies submitted to Zn rates, relating the plants’ response to Zn level in both soil and plant. The experiment had a factorial arrangement 4 x 3 [four Zn rates (0, 1, 2, and 3 mg kg-1) and three cultivars (variety Al-Manduri, double-cross hybrid C 701, and triple-cross hybrid P 3041)] in a completely randomized design. Hybrids C 701 and P 3041 needed higher Zn rates than the Al-Manduri variety to express maximum dry matter production of the plant shoot, which was associated with different requirements of each cultivar for available Zn in soil. On the other hand, Al-Manduri and P 3041 cultivars presented a higher Zn use efficiency than the C 701 cultivar. The hybrids had Zn critical level higher than the variety, both in soil and plant.

O experimento consistiu de um fatorial 4 x 3 [quatro doses de Zn (0, 1, 2 e 3 mg kg-1) e três cultivares (variedade Al-Manduri, hídrido duplo C 701 e híbrido triplo P 3041, definidos comercialmente como sendo de baixa, média e alta tecnologia, respectivamente)] em delineamento inteiramente casualizado. Os híbridos C 701 e P 3041 necessitaram de doses mais elevadas de Zn do que a variedade Al-Manduri para expressarem a produção maxima de massa seca da parte aérea, o que foi associado à exigência diferenciada de cada cultivar em Zn disponível no solo. Por outro lado, os cultivares Al-Manduri e P 3041 foram mais eficientes no uso em Zn do que o cultivar C 701. Tanto no solo como na planta, os híbridos apresentaram nível crítico de Zn mais elevado do que a variedade.Universidade Estadual de Maringá2007-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/x-forcedownloadhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/25610.4025/actasciagron.v29i2.256Acta Scientiarum.
