Resumo:   This study shows an economic analysis of 10 production systems of black- wattle which were sampled in 23 farms with know- how in cultivating this species. The analyzed systems utilizing regeneration induced by fire were: black- wattle (BW) alone (S1), BW associated with corn (S2), BW associated with beans (S3), BW associated with potatoes (S4). The planting systems analyzed were: BW alone (S5), BW alone in crop succession (S6), BW associated with water- melon (S7), BW with eans (S9), and BW with cattle (s10). For the economic analyses the following parameters were utilized: Discounted Net Worth (DNW), Soil expectation value (SEV), Benefit- cost ratio (B/C), Internal rate of return (IRR). The optimum age for rotation of the black- wattle through the maximization of the DNW, was 7 years for interest rates, varying from 6 to 10% year in all the production systems analyzed. In new areas where the dire regeneration system is not possible, the most profitable and efficient system utilized was the association of black- wattle with water- melon. Tis was due to the DNW, that in a rate of 6% per year resulted in 1, 436.06 US$/ has and B/C, that was 2.13 for sites with average productivity of 227 st/ ha wood, and 14 tons/ha of dried bark with 12% humidity at 7 years age. In areas where is possible to utilize  regneration induced by fire, the association with potatoes sites, the PNW and B/C, in a rate of 6$ per year, resulted in 1,063.99 US$/ha and 2.13 respectively.

Neste trabalho foi feita a análise econômica de dez sistemas de produção de acácia-negra, amostradas em 23 propriedades rurais localizadas nos municípios com tradição na acacicultura. Foram analisados os seguintes sistemas que utilizam a regeneração induzida pelo fogo: acácia-negra (AN) em monocultivo (S1), AN com milho (S2), com feijão (S3) e com batata inglesa (S4). Os sistemas de plantio de mudas analisadas foram: AN em monocultivo (S5), monocultivo de AN em sucessão agrícola (S6), AN em consórcio com melancia (S7), com milho (S8), com feijão (S9) e com pecuária (S10). Para a análise econômica foram utilizados os critérios do Valor Liquido Presente (VLP), Valor Esperado da Terra (VET), Razão Beneficio/Custo (RBC) e Taxa Interna de Retorno (TIR). A idade de rotação otimizada da acácia-negra através da maximização do VLP, foi igual a 7 anos para taxas de juros que variam de 6 a 10% a.a., em todos os sistemas de produção. Em áreas novas, ou onde a regeneração pelo fogo não é possível, o sistema mais eficiente e rentável foi o plantio de mudas consorciado com melancia, pois o VLP, a taxa 6% a.a., foi de 1.436,06 US$/ha e o RBC foi 2,13, para sítios com produtividades médias de 227 st/ha de madeira comercial e 14 t/ha de casca seca a 12% de umidade, aos 7 anos de idade. Em áreas onde é possível a regeneração induzida pelo fogo, o consórcio com batata inglesa é o mais rentável, pois aos 7 anos, em sítios médios o VLP e o RBC, a taxa 6% a.a., foram 1.063,99 US$/ha e 2,13, respectivamente.Universidade Federal de Santa Maria1999-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/29410.5902/19805098294Ciência Florestal; Vol. 3 No. 1 (1993); 203-240Ciência Florestal; v. 3 n. 1 (1993); 203-2401980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/294/pdfFleig, Frederico DimasSchneider, Paulo RenatoBrum, Eliege Terezinhainfo:eu-repo/semantics/openAccess2017-08-29T21:06:53Zoai:ojs.pkp.sfu.ca:article/294Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-08-29T21:06:53Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
