Establishment of seedlings of leguminous species introduced in lowland pastures

Abstract

The introduction of unprotected young plants of 16 leguminous tree species inta Brachiaria decumbens pastures under grazing was evaluated in three different moments of the year at the Seropedica, RJ. Nine variables related to length and number of sproutings were used for the evaluations before and after animal grazing. The statistical difference of the means by the Scott-Knott test of the 48 treatments of the principal canonical variable, suggested the formation of three groups. Difference among treatments means for each variable, calculated by Bonferroni confidence intervals, revealed that Jurema Preta (Mimosa tenuiflora) presented the greatest length and the highest number of sproutings, the shortest differences of length and number sproutings and the lowest loss in the percentage of sproutings after animal grazing. The results related to the variables after grazing obtained from Jurema Preta confirm its recommendation for the region as the leguminous tree with the highest chances of growth whether introduced into pastures under grazing without protection.
