Resumo: | The effect of zinc applied in seeds on the nutrition of sorghum is affected by the sources and applied rate. The present work aimed to evaluate zinc application, from two sources, on the nutrition and initial growth of a culture of sorghum cv. BRS 304, cultivated in sand. The treatments consisted of five rates (0, 14.3, 28.6, 57.2 and 114.4 g kg-1 of seed) and two zinc sources – sulphate (22% Zn) and oxide (50% Zn). At 25 days after sowing, the plants were cut. The aerial and root dry mass was evaluated, and the levels and accumulation of Zn in the plants were determined. The application of 14 g Zn kg-1 of seeds, in oxide form, provided adequate initial growth of sorghum cv. BRS 304. The sulphate source promoted greater absorption of Zn for the plants, reaching in its highest dosis, high levels of the nutrient in the aerial part (> 4170 mg kg-1) and developing characteristic symptoms of phytoxicity. |

O presente trabalho objetivou avaliar a aplicação de zinco, a partir de duas fontes, sobre a nutrição e o crescimento inicial da cultura do sorgo cv. BRS 304, cultivado em areia. Os tratamentos foram cinco doses (0; 14,3; 28,6; 57,2 e 114,4 g kg-1 de semente) e duas fontes de zinco, o sulfato (22% de Zn) e o óxido (50% de Zn). Aos 25 dias após a semeadura, efetuou-se o corte das plantas, e avaliou-se a massa seca da parte aérea e das raízes, e determinou-se o teor e o acúmulo de Zn nas plantas. A aplicação de 14 g Zn kg-1 de sementes, na forma de óxido, proporcionou adequado crescimento inicial do sorgo cv. BRS 304. A fonte sulfato promoveu maior absorção do Zn pelas plantas, atingindo, na maior dose, alto teor do nutriente na parte área (> 4170 mg kg-1) e o desenvolvimento dos sintomas característicos de fitotoxicidade.Universidade Estadual de Maringá2008-10-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/530010.4025/actasciagron.v30i4.5300Acta Scientiarum.
