The objective of this study was to evaluate the influence of Urochloa brizanthavar. Marandu on the growth and accumulation of macronutrients in the leavesof Cordia trichotomaand Guarea guidonia. Seedlings of tree species were transplanted to 18-liter pots and kept free of U. brizanthafor three months. After that period, three treatments were adopted that consisted of the control (T0), two plants of U. brizanthaper pot (T2) and four plants of U. brizanthaper pot (T4). Growth and nutrient accumulation of tree species were evaluated after 84 days of coexistence with U. brizantha. The increment in diameter, of both tree species, leaf area and shoot dry matter of G. guidoniawere significantly affected by the presence of U. brizantha, compared to the control. Significant differences were observed for the accumulation of potassium and magnesium in the leaves of C. trichotoma.Keywords:weed competition,growth of tree species, Cordia trichotomaand Guarea guidonia |
