FORMAS DE APLICAÇÃO DE MANGANÊS NO CRESCIMENTO DO FEIJOEIRO COMUM CULTIVADO NO CERRADO

Abstract

Due to its formation process, Cerrado soils have low levels of micronutrients, including manganese. The objective of this work was to verify the effect of ways to apply manganese to common beans grown in the Cerrado. O experiment was carried out in a greenhouse at Escola Fazenda and Multi-User Natural Sciences Laboratory of the Federal Institute of Goiano - Campus Posse, Goiás. The design used was completely randomized, with four treatments and ten replications. Four forms of fertilizer were tested with Mn: soil, seed, foliar and control in common bean cultivar BRS FC 401. The variables analyzed were the height of the aerial part, stem diameter, dry mass of the aerial part, dry mass of the root, chlorophyll content and SPAD index. The data was subjected to the F test and in cases of significant effect, the means were compared using the Tukey test. The forms of Mn fertilization did not interfere in the components of bean growth under the evaluated conditions.
