Resumo: The zinc application in sorghum seeds can affect the nutrition and the initial growth of the plants. Thus, the objective of their study was to evaluate the zinc application in the form of sulphate and oxide on the nutrition and on the initial growth of the plant of sorghum cv. BRS 310. The treatments had been five rates 0; 14,3; 28,6; 57,2 and 114,4 g Zn kg-1 of seeds and two zinc sources, the sulphate (22% of Zn) and the oxide (50% of Zn). The experimental units were translucent polyethylene trays a filled with 5 L of washed thick sand, with 50 seeds of sorghum cv. BRS 310. The plants were cut 25 days after the sowing, and were evaluated for dry matter of above ground parts and the roots and it was determined the content and the accumulation of Zn in the plants. The zinc application in the oxide form promoted greater increment of dry matter in sorghum plants and provided to greater efficiency of use of the micronutrient, even so, with lesser efficiency of absorption, when compared the source sulphate. The source sulphate caused reduction in the production of the mass of the dry matter of sorghum. The sources had promoted alteration in the absorption of other nutrients for the sorghum plants, being that the source sulphate developed the absorption of P, Ca, S and Mn and the source oxide bigger absorption of K, Mg, Cu and Fe.

Assim, objetivou avaliar a aplicação de zinco na forma de sulfato e de óxido sobre a nutrição e o crescimento inicial da planta do sorgo cv. BRS 310. Os tratamentos foram constituídos de cinco doses 0; 14,3; 28,6; 57,2 e 114,4 g kg-1 de semente e de duas fontes de zinco, o sulfato (22% de Zn) e o óxido (50% de Zn). Cada unidade experimental constituída de bandeja de polietileno translúcido preenchida com 5 L de areia grossa lavada, com 50 sementes do sorgo cv. BRS 310. Aos 25 dias após a semeadura, efetuouse o corte das plantas, 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 zinco na forma de óxido promoveu maior incremento de matéria seca em plantas de sorgo e proporcionou maior eficiência de utilização do micronutriente, embora, com menor eficiência de absorção, quando comparado a fonte sulfato. A fonte sulfato causou diminuição na produção da massa seca do sorgo. As fontes promoveram alteração na absorção de outros nutrientes pelas plantas de sorgo, sendo que a fonte sulfato incrementou a absorção de P, Ca, S e Mn e a fonte óxido maior absorção de K, Mg, Cu e Fe.UEL2007-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/295810.5433/1679-0359.2007v28n3p355Semina: Ciências Agrárias; Vol. 28 No. 3 (2007); 355-364Semina: Ciências Agrárias; v. 28 n. 3 (2007); 355-3641679-03591676-546Xreponame:Semina.
