Summary in the original language of the document
O objetivo deste trabalho foi avaliar o desenvolvimento de leguminosas herbáceas perenes semeadas na época das águas no sul do Tocantins, onde foram utilizadas: cudzu tropical (Pueraria phaseoloides), siratro (Macroptilium atropurpureum) e centrosema (Centrosema pubescens). O estudo foi conduzido na Universidade Federal do Tocantins, no município de Gurupi-TO, com delineamento experimental em blocos casualizados com quatro repetições avaliando: velocidade de emergência; capacidade de cobertura do solo; supressão sobre as plantas invasoras; decomposição e acúmulo de nutrientes na parte aérea. O siratro apresentou maior velocidade de emergência, enquanto o cudzu tropical obteve crescimento mais lento, porém reduziu maior número de plantas invasoras. Não foi observada diferença significativa entre os tratamentos na decomposição dos resíduos. A centrosema proporcionou maior aporte de N e P, e quanto aos demais macronutrientes, não foi observada diferença estatística.
Summary translation
This research has the aim of generate informations about perennial herbaceous leguminous cultivated during rainy season. The leguminous studied were: kudzu (Pueraria phaseoloides), siratro (Macroptilium atropurpureum) and centrosema (Centrosema pubescens). The research was settled in Federal University of Tocantins, in Gurupi. The experimental design were randomized blocks with four repetitions, being evaluated: sowing speed in days, soil coverture in percentage, suppression of weeds capacity through number of species and its dry biomass, dry biomass of leguminous decomposition using straw weight during time and nutrients in aerial biomass. The siratro showed the highest rate of emergency, while the tropical kudzu had slower growth, but decreased as many weeds, and there was no statistical difference between treatments concerning decomposition of waste. The centrosema has provided major input of N and P, though the other macronutrients, there was no statistical difference.
