Resumo
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.
