Crescimento de mudas de Anadenanthera macrocarpa (Benth) Brenan (angico -vermelho) em substrato fertilizado e inoculado com rizóbio Growth of Anadenanthera macrocarpa (Benth) Brenan -red antigo- seedlings in a fertilized substrate with Rhizobium inoculation

Abstract

Foram produzidas mudas de Anadenanthera macrocarpa (angico- vermelho) em sacos de polietileno (18 x 15 cm), usando-se como meio de crescimento substrato peneirado constituído de bagaço de cana-de-açúcar e torta de filtro de usina açucareira (3:2, v:v). Objetivou-se avaliar o efeito de adubação e inoculação com rizóbio, sobre a qualidade das mudas. Instalaram-se dois experimentos, conduzidos em delineamento inteiramente casualizado, com três repetições, sendo adicionado em cada um, separadamente, o sulfato de amônio e o nitrato de amônio, em diferentes doses. Aos 180 dias após a semeadura, as mudas foram avaliadas em altura (H), diâmetro do colo (D), relação H/D, pesos de matéria seca do sistema radicular e da parte aérea, área foliar e o potencial de regeneração de raízes das mudas. Concluiu-se que a inoculação com rizóbio foi suficiente para a produção de mudas de angico nesse substrato e a fertilização estudada não trouxe ganhos ao crescimento das mudas.Seedlings of Anadenanthera macrocarpa (red angico) were grown in 18 x 15 cm black polyethylene bags. The growth medium was sieved and mixed with residues of sugarcane bagasse + decomposed filter cake (3:2, v:v) The objective was the evaluation of the fertilization and inoculation with Rhizobium on the quality of the seedlings. Two experiments were carried out. In each one, separately, ammonium sulfate and ammonium nitrate were added, in three different doses. In both experiments, a specific Rhizobium species was also inoculated together with the seeds. A completely randomized design with three replicates was used. At 180 days after sowing, the seedlings were evaluated for height (H), root collar diameter (D), H/D ratio, shoot and root dry matter weights, leaf area and root regeneration potential. It was concluded that inoculation with Rhizobium was sufficient to stimulate growth of "red-angico" seedlings in this substrate. The tested fertilizers were not efficient for the stimulation of seedling growth.
