Abstract:

The zinc is a micronutrient that helps in the production of the maize in Brazil, but is a very common deficiency found in all the regions of the country. With the objective of evaluating the effect of the zinc rates in micronutrients concentration in soil, in plants and maize shoot dry matter production, an experiment was done in pots containing Haplustox (Latossolo Vermelho). It was used as a complete randomized design, with three replications of treatments; in a factorial arrangement 6x3 (six rates of zinc and three sources). It was used at following rates of zinc: 0; 0.5; 1; 2; 4 and 6 mgkg-1, and sources: ZnEDTA, Zn-lignosulfonate (Zn-LS) and zinc sulfate. It was observed zinc application increases the initial growth of maize crops, with the 90% of maximum production in 0.9 mgkg-1 zinc concentrations in soil and 16 mgkg-1 in plants. The source of Zn-lignosulfonate proportioned the highest Zn concentration in soil and plant; therefore it isn’t observed difference among the sources in nutrients absorption and dry matter production. The increased zinc rates increased concentration in plants, in soil and Zn accumulated. It was observed a few answers in dry matter production with rates application above 2 mgkg-1.
