Resumo

Foliar fertilization with macro and micro minerals for the forage grasses establishment can be a less costly alternative for the farmer, however the possible beneÀ ts of this management technique still need to be better studied. The objective with this work was to evaluate the physiological, productive and structural responses of grasses of the Urochloa genus, depending on the application or not of foliar fertilizer during the plant establishment. Four experiments were carried out, in each of which one of the following forage grasses was evaluated: Urochloa brizantha cv. Marandu, Urochloa spp. Mulatto II, Urochloa spp. Mavuno and Urochloa spp. Ipyporã. All the experiments were carried out from November 2018 to March 2019, in a completely randomized design, with four replications. The experimental area of each experiment consisted of four plots with 12.25 m², where half the area of the plots received foliar fertilizer (FH PASTAGEM FOLIAR, with 14% N; 12% P; 12% K; 0.38 % Mg; 10.2% S; 0.24% Cu; 0.18% Mn and 0.63% Zn) and the other half did not. The response variables were evaluated: spad index, leaf area index, canopy light interception, forage production and root density. In all experiments, the foliar fertilizer application during the establishment of Marandu, Mulato II, Mavuno and Ipyporã grasses did not inÁ uence (P>0,05) the spad and leaf area indexes, forage production and root density.(AU)
