ADUBAÇÃO MINERAL DA CANDEIA (Eremanthus erythropappus DC.) McLeish)

Mineral fertilization of candeia (Eremanthus erythropappus (DC.) McLeish). This study evaluated the nutritional aspects and the effect of nutrient omission in development of candeia seedlings (Eremanthus erythropappus (DC.) McLeish). The experiment, based on missing-nutrient technique, was developed in a greenhouse, and used as substrate a low fertility oxisoil on 10 treatments, arranged in fully randomized block design, with 5 replicates and one plant per pot. It was applied a complete treatment with (N,P,K,Ca,Mg,S,B, and Zn), other eight elements with one missing element at a time (-N, -P, -K, -Ca, -Mg, -S, -B, and -Zn), and a control (natural substrate). The evaluation after 110 days measured the following variables: total height, ground level diameter, and dry matter. Based on the results allow the following conclusions: a) Candeia is strongly exigent in P and N; b) The level of natural soil's fertility did not allow the development of candeia's seedlings; c) Candeia's nutritional limitation in decreasing order is P > N > S > Mg = B > Ca > K > Zn.
