The aim of this study was to evaluate the influence of different spacing arrangement between plants (12.5, 15.0, 17.5 and 20.0 cm) and types of broiler manure (with base residue shavings and rice hulls added in soil cover and without the addition of broiler manure), in the productivity and profitability of tannia. The treatments were arranged in a 4 x 3 factorial scheme, in a randomized complete block design, with four replications. The highest yields were obtained in the smallest spacing (12.5 cm), presenting maximum values of 1.25 t ha-1, for the mother cormel and 4.20 t ha-1, for commercial cormels, with increases of 0.59 and 2.78 t ha-1, respectively, in relation to the spacing of 20 cm between plants, which was the one that obtained the lowest productive means. The costs estimated to produce 1.0 ha of tannia as a function of the treatments under study varied by R1,619.06betweenthehighestcost(R 9,917.36), determined for cultivation in spacing of 12.5 cm and the lowest cost (R 8,298.30),forcultivationat20cmspacingwithouttheadditionofbroilermanuretothesoil.Inordertoobtainhigheryieldsandhighergrossandnetincomeofcommercialcormelsoftannia,thecultivationshouldbedoneataspacingof12.5cmbetweenplantsandwithadditionofbroilermanurewithofricehuskbaseresidueOobjetivodestetrabalhofoiavaliarainflue^nciadediferentesespac\c​amentosentreplantas(12,5;15,0;17,5e20,0cm)etiposdecamadefrangoadicionadasaosolo(combasesmaravalhaecascadearrozesemcamadefrango),naprodutividadeerentabilidadedomangarito.Ostratamentosforamarranjadosnoesquemafatorial4x3,nodelineamentoexperimentalblocoscasualizados,comquatrorepetic\c​o~es.Asmaioresprodutividadesforamobtidassobomenorespac\c​amento(12,5cm),apresentandovaloresmaËŠximosde1,25tha−1,pararizomama~ee4,20tha−1,pararizomafilhocomercializaËŠvel,comaumentosde0,59e2,78tha−1,respectivamente,emrelac\c​a~oaoespac\c​amentode20cmentreplantas.Oscustosestimadosparaproduzir1,0hademangaritovariaramemR 1.619,06, entre o maior custo (R9.917,36),paraocultivosobespac\c​amentode12,5cmeomenorcusto(R 8.298,30), sob espaçamento de 20 cm, sem a adição de cama de frango.
