Este trabalho apresenta os sistemas tradicionais de plantio da cultura da mandioca, resultados de pesquisas e perspectivas para melhorar os sistemas consorciados onde essa cultura e o componente basico. A mandioca e consorciada tradicionalmente com milho e feijao (ou caupi), individualmente ou os dois ao mesmo tempo. A vantagem desta cultura no plantio consorciado em diferentes sistemas variou de 60 a 90% em relacao ao plantio isolado. O plantio de mandioca em fileiras duplas com espacamento de 2,0 m x 0,60 m x 0,60 m melhora a producao das culturas no consorcio, mas menhum estudo testou se este efeito pode ser obtido em fileiras simples com espacamentos maiores. As seguintes areas de estudo poderiam receber mais atencao em futuras pesquisas: a) identificacao de genetipos compativeis para o consorcio; b) definicao de niveis e metodos eficientes de adubacao, principalmente nas areas que tem boa precipitacao pluviometrica; c) efeito do consorcio na ocorrencia de pragas e doencas; d) perspectivas para a consorciacao com culturas alternativas como soja, amendoim, girassol e sorgo; e) possibilidade da consorciacao da mandioca colhida aos doze meses; f) comparacao de sistemas alternativos, em conjunto com diferentes praticas e manejo do solo. |

Although agriculture and livestock systems represent important sources of N2O from the soil, they may also aid in emissions mitigation, mainly when integrated systems are taken into account, such as crop-livestock-forest, for food production. This work assessed the soil N2O emissions from a tropical Oxisol under row-crop, livestock, forest monocultures, and an integrated crop-livestock-forest system in the Southern Amazon - Brazil. Soil N2O emissions were measured using static chambers from November 2014 to October 2016 in four soil use systems [row-crop, livestock, forest, and integrated crop-livestock-forest (CLF)], and in a reference area under native forest fragment. For the whole period, the average of soil N2O fluxes was 16.9, 12.2, and 15.4 ug N2O-N m-2 h-1, to row-crop, livestock, and CLF systems, respectively, all with a similar average among them. The lowest fluxes were observed in the forest system and native forest fragment, with average fluxes of 4.0 and 6.3 ug N2O-N m-2 h-1, respectively, both lower than the agricultural systems. The largest soil N2O fluxes were observed throughout the rainy seasons in the row-crop, livestock, and CLF, mostly after N-fertilizer application to the soil surface or in the planted row. As a consequence, the cumulative emissions were greater in row-crop, livestock, and CLF systems, which in the averages of two cycles emitted respectively 1.40, 1.15, and 1.27 kg N2O-N ha-1 yr-1, all different of the forest system and native forest fragment (0.33 and 0.52 kg N2O-N ha-1 yr-1, respectively). Nitrogen fertilization and soil moisture influenced soil N2O emissions of all systems assessed in the Southern Amazon. The N2O emissions took place after both factors were met, corroborating the hole-in-the-pipe model. Even with more soil use intensification, once in the same area there were three cultures in succession during a year and perennial trees, CLF did not lead to greater N2O emissions from the soil than row-crop and livestock. Thus, CLF represents a good option for N2O mitigation for the edaphic and climatic conditions of the Southern Amazon.
